## Title
Real time video special effects system and method

## Abstract

The present technology is a graphical user interface for a video recording system and method of recording a video while applying special effects in real time prior to and/or while recording. The interface is associated with an electronic device including a processor in communication with a camera and a memory unit. Inputs from the interface are utilized by the processing unit to determine if the native speed rate of the raw video data is to be changed, and if so then modifies at least one frame in the raw video data to create a modified video data at a modified speed rate that is different to the native speed rate. The system then generates an output video feed that is displayed in the graphical user interface. This allows for the continuous recording of video from the camera or video feed at different speed rates without altering camera operations or settings.

BACKGROUND
Technical Field
The present technology relates to a real time video special effects graphical user interface, system and method for use in connection with controlling or creating special effects in video recordings while recording is in progress. More particularly, the present technology relates to an interface associated with a system and method of decoding and altering a speed rate of a video stream from a device live or in real time prior to being recorded and written to long term memory storage with no post editing.
Background Description
Modern video formats utilize a variety of frame rates. Film, which was almost universally shot at 24 frames per second, could not be displayed at its native frame rate, which required pulldown conversion, often leading to “judder”. For example, to convert 24 frames per second into 60 frames per second, every odd frame is doubled and every even frame is tripled, which creates uneven motion. Other conversions have similar uneven frame doubling. Newer video standards support 120, 240, or 300 frames per second, so frames can be evenly multiplied for common frame rates such as 24 frames per second (fps) film and 30 fps video, as well as 25 and 50 fps video in the case of 300 fps displays. These standards also support video that is natively in higher frame rates, and video with interpolated frames between its native frames.
Native camera applications (app) in devices running on electronic devices, such as smartphones, can record in regular time and then process the video data stream to create slow motion and in speed up time or time-lapse. However, these known systems or methods do not utilize a user interface where the user can manually control the “time special effects” within the video in real time while recording. For example, the native camera app in the Samsung Galaxy S9+® has a special effect feature where the camera changes the frames per second capture rate when the app detects that the an object has crossed inside a portion of the screen, as indicated with a box outline in the middle of the screen in this case.
Third party apps like Instagram®, Facebook® and Snapchat® uses cameras from mobile devices, but these apps have no feature that allows the user of the app to modify the slowing down or speeding up of the recording speed in real time while recording is in progress.
With higher end feature-rich camera apps like FILMiC Pro®, users can preset the recording frame rate speed and playback frame rate speed independently of each other, thus, creating slow motion and speed up effects in the final produced video.
Time remapping of optical flow is known like with Premiere Pro CC 2015, which enables users to achieve smooth speed and framerate changes by interpolating missing frames. Optical Flow interpolation modifies the speed of clips containing objects with no motion blur that are moving in front of a mostly static background that contrasts highly with the object in motion.
Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid and to compensate for display motion blur.
It can be appreciated that the use of motion interpolation as it reduces motion blur produced by camera pans and shaky cameras and thus yields better clarity of such images. It may also be used to increase the apparent framerate of video game software for a more realistic feel, though the addition of input lag may be an undesired side effect. This “video look” is created deliberately by the Video Field Interpolation Restoration Effect (VidFIRE) technique to restore archive television programs that only survive as film telerecordings. VidFIRE is a restoration technique intended to restore the video-like motion of footage originally shot with television cameras now existing only in formats with telerecording as their basis. The main differences between an artificially and naturally high framerate (via interpolation versus in-camera), are that the latter is not subject to any of the aforementioned artifacts, contains more accurate (or “true to life”) image data, and requires more storage space and bandwidth since frames are not produced in real time.
Motion compensation is an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current picture. The reference picture may be previous in time or even from the future. When images can be accurately synthesized from previously transmitted/stored images, the compression efficiency can be improved.
Motion compensation exploits the fact that, often, for many frames of a movie, the only difference between one frame and another is the result of either the camera moving or an object in the frame moving. In reference to a video file, this means much of the information that represents one frame will be the same as the information used in the next frame.
Using motion compensation, a video stream will contain some full (reference) frames; then the only information stored for the frames in between would be the information needed to transform the previous frame into the next frame.
Frame Blending may be another technique known to those skilled in the art. In some footage, using Optical Flow for creating smoother motion may not produce the desired results. In such scenarios, you can use one of the other time interpolation options—Frame Sampling or Frame Blending. Frame Sampling repeats or removes frames as needed to reach the desired speed. Frame Blending repeats frames, and it also blends between them as needed to help smooth out the motion.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a real time video special effects system and method that allows creating special effects in video recordings while recording is in progress.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.
It is known that video recordings are made up a series of frames or group of pictures displayed at a speed rate to create motion. These frames of images or video can be characterized as digital frame data, which can be buffered in the playing back of the video. The frame rate (expressed in frames per second or fps) is the frequency (rate) at which these consecutive frames appear on a display. This can be applied equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the frame frequency, and be expressed in hertz.
Real-time recording and/or playback of video is typically performed at a rate of thirty (30) fps. It is desirable in several situations to speed up or slow down the playback of the video. This is typically conducted while keeping the recording and playback frames per second at 30 fps in order to maintain compatibility with the existing components, such as the display devices, etc. For example, if a viewer wanted to speed up the playback of a video by a certain percentage from the standard real-time playback speed while keeping 30 fps, the information or data of a specific number of frames is required to be played back in a time segmented for 30 frames. A scheme to create this is to skip one frame, from the recorded video, out of every predetermine number of frames so that the appropriate number of frames of video are displayed at 30 fps. It is noted that these known systems and methods are provided as a post-recording process, which skips frames from a 30 fps recording. The recording is initially written to memory in real time at 30 fps, with no special effects.
The present technology solves the problem of requiring “post production editing” to insert the time modification special effects, which can be time and resource costly, especially for amateur filmmakers.
Furthermore, the present technology solves the problem of pre-setting the motion recording speed to either fast motion or slow motion where user cannot adjust the motion recording speed in real time during the recording process.
Even still further, the present technology solves the problem of presetting the motion recording speed where a user cannot adjust the motion recording speed continuously and vary from fast motion to slow motion in real time during the recording process.
The present technology alleviates and solves the issue requiring hardware support for every device. By using the software algorithm to simulate slow motion, it is not device dependent and the resulting file is much smaller than hardware supported slow motion video.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned devices or systems do not describe a real time video special effects system and method that allows creating special effects in video recordings while recording is in progress. The present technology additionally overcomes one or more of the disadvantages associated with the prior art by adding or removing frames from the frame strip provided by the camera in real time.
Still further, there is no known interface for the user to change the speed of recording and the duration to apply the special effects in real time while recording is in progress. Furthermore, the scene has to be relatively fixed, with the camera not panning or following the action. The algorithm associated with this known system uses a motion sensor while the camera remains steadily fixed on a scene and the subject has to traverse the scene while the rest of the scene remains fixed.
The present technology can utilize a graphical user interface associated with the electronic device that modifies the frames from a camera in real time prior to recording or saving.
A need exists for a new and novel real time video special effects system and method that can be used for creating special effects in video recordings while recording is in progress. In this regard, the present technology substantially fulfills this need. In this respect, the real time video special effects system and method according to the present technology substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of creating special effects in video recordings while recording is in progress.
Users of the present technology can in “real time” produce videos that contain the special effect of user controlled variable time modification, aka fast motion or slow motion, by using the user interface programmed into the device's apps that run on their supported operating systems, and other embedded devices. The produced video is taken in one-shot, with all of the time modification commands entered in real time while recording.
For exemplary purposes, the present technology can utilizes a set video frame rate to 30 fps, resulting in 30 frames per second while recording.
In some embodiments of the present technology, a user can utilize a fast forward option of the present technology, which results in dropping frames according to the set fast forward rate (like 1×, 2×, 3×, etc.). If the user sets 2× fast forward video then the present technology can append the 1st frame in writer and skips the 2nd frame, then write the 3rd frame, and then skip the 4th frame and so on. The resultant video that is recorded is at the predefined fast forward speed in real time while retaining a 30 fps.
In some embodiments, a user can utilize a slow motion option of the present technology, which results in appending a same frame twice thereby repeating this frame so the final video that is recorded is in slow motion. For example, if the user sets 2× slow video then the present technology can append the 1st frame in writer, and the same frame append to the next time/frame slot. The resultant video that is recorded is at the predefined slow motion speed in real time while retaining a 30 fps.
The present technology allows the user to control the recording device's (and any other video recording device) recording speed and other camera settings while recording through the use of the custom user interface, such that when the user plays the video immediately after the present technology algorithm has processed the commands, the playback speed of the scenes correspond with the commands during recording. The present technology accomplishes this with software simulation without having to increase the recording device's frame rate and is not device dependent and works across all platforms.
An additional aspect of the present technology can be to increase the frame rate of the recording device while recording is in progress. This requires application programming interface (API) access to limited number of supported hardware and there is no industry standard API, which limits the number of supported devices. The display shows the current time recording rate, from normal speed to 3× faster, or −3× slower (can be 4×, 5× or more). The user can control the recording rate by utilizing the interface.
Numerous advantages exist with the present technology, such as an easy to use custom user interface, wherein the user can add special effects of time modification into the video in real time while recording is in progress. This is an advantage over existing technology because the user can produce a video with the special effects (variable fast and slow motion recording speeds) while recording of that video is in progress. This reduces the time and costs to produce videos with these kinds of special effects by not requiring a separate video editing software and or paying a video editor to edit and produce a comparable video. User can enjoy viewing the videos they created with the special effects immediately once they have completed recording and brief processing time for the device to process adding the special effects and automatically producing a new video with the special effects implemented.
Another advantage of user's manual control of the special effect in real time is that the user can pan along with the movement of the scene, and capture the peak moment of the action and use continuously variable slow/fast motion at just the right time and for as long as desired, and then return back to normal speed as the user is recording.
Still another advantage is that the present technology is not hardware dependent for the slow or fast motion special effect to work. The software algorithm simulates the slow or fast motion.
Even still another advantage is that with the manual user interface, the camera does not have to remain stationary while pointing at a stationary scene for an AI software to determine the “action” to apply the special effects thereto.
Another advantage is that the present technology can accept input from, but not limited to, a remote camera feed, a joystick, a retina scanner, a body suit controller, on-screen subject gestures and a tactile user interface.
In some embodiments, the present technology can also be applied to add time modifying special effects to pre-existing videos. The user can control the time variable in the playback by using the same familiar easy to use left-right on a compatible device, such as a smartphone or tablet, to control and modify the values for the playback time value, from −3× to 4× in this case. It can be appreciated that there are additional abilities to the factor of time modification once digital processing technology has advanced sufficiently to be able to interpolate data and images in between frames captured one the video.
When the user slides towards the 4×, the recorded speed is played back faster than normal, up to 4× faster. When the user slides towards the −3×, the recorded speed is played back slower than normal, up to 3× slower.
In some embodiments, the raw video data can include data such as, but not limited to, streaming video data, video, audio, depth, object identification, histogram, and combination thereof.
In some aspects, the processing unit can be configured or configurable to preclude the raw video data from being written to the memory unit from the camera, such that the present technology can intercept the raw video data.
In some embodiments, the input can be one or more desired speed rate values that the modified speed rate is based on. Where the modified speed rates can be one of less than the native speed rate or greater than the native speed rate.
If the modified speed rate is less than the native speed rate, then the processing unit can be configured or configurable to add at least one frame to the raw video data to create the modified video data.
If the modified speed rate is greater than the native speed rate, then the processing unit can be configured or configurable to remove at least one frame from the raw video data to create the modified video data.
If the input is not a request to change the native speed, then the processing unit can be configured or configurable to keep all the frames from the raw video data and write the raw video data to memory.
In some embodiments, the interface can be a graphical user interface including a portion configured or configurable to generate the input that is associated with the native speed rate or the modified speed rate. The graphical user interface can be configured or configurable to display the output video recording data in real time with receiving the raw video data from the camera. The output video recording data can be configured or configurable to include a combination of the raw video data and the modified video data, with a transitioning between the raw video data and the modified video data being dependent on the input. It can be appreciated that the interface can be a joystick or can utilize a joystick.
In yet another aspect, the interface can be operable associated with at least one computer-readable storage media storing instructions that, when executed by the processing unit or a processor of a computer system, causes the processing unit to direct the raw video data from the camera to the processing unit and as well as to the memory unit in real time with receiving the raw video data from the camera, and to write the raw video data from the processing unit to the memory unit or apply at least one algorithm to the raw video data to create the modified video data and write the modified video data from the processing unit to the memory unit.
According to yet another aspect of the present technology, the present technology can be a method of recording a video at one or more speed rates in real time with receiving the raw video data from the camera.

Referring now to some embodiments in more detail, new and novel real time video special effects system and method 10 of the present technology for creating special effects in video recordings while recording is in progress is illustrated and will be described with reference to FIG. 1. More particularly, the real time video special effects system and method 10 can include a camera 12, an image processor or processing unit 14, a user interface 30 associated with the processing unit, a storage or memory unit 18, a display unit 20. At least one RAM memory and/or at least one non-volatile long term memory can be operably connected or connectable with the processing unit 14. It can be appreciated that the camera 12 can be any device capable of capturing images and/or video, and can be associated or integrated with a microphone 16. The image processing unit 14 is in operable communication with the camera 12, microphone 16, the memory unit 18 and/or the display unit 20. The image processing unit 14 intercepts the raw video data from the camera 12 and/or microphone 16, processes the raw video data in real time in possible accordance with at least one algorithm, and then records output/final video recording data in the memory unit 18 and/or displays the output/final video recording data in the display unit 20.
It can be appreciated that the system 10 can be configured or configurable as a complete video system of an electronic device having one or more video cameras 12, one or more display devices 20, and one or more integrated circuits or processors. Alternatively, it can be appreciated that the imaging processing unit 14 can be configured or configurable as a module or integrated circuit chip embedded in the electronic device or with a component of the electronic device.

With reference to FIG. 2, the processing unit 14 can be configured or configurable to receive an input of a user selection of a requested recording speed. The raw video data from the camera 12 can be diverted to the imaging processing unit 14, where the program and/or algorithm modifies or retains the raw frames contained in the raw video data from the camera 12.

When actuated or while in operation, the imaging processing unit 14 intercepts the raw video data 22 from the camera 12, which includes a series of frames #1-#n at a native frame rate for proper presentation by the display unit 20. For exemplary purposes, the frame rate shown in FIG. 3A can be 30 fps. The imaging processing unit 14 receives the raw frames 22 and then can modify or retain the raw frames dependent on one or more inputs signals received by the imaging processing unit 14.

Raw frame #1 can be appended in writer, the raw frames #2 and #3 can be skipped/dropped, then raw frame #4 can be written, then raw frames #5 and #6 can be skipped/dropped, and then raw frame #7 can be written, and so on until a modified or output video recording data 24 is generated in 3× fast motion speed. This process is conducted in real time, and the fast motion output video is recorded in place of the raw video data 22, and/or displayed in real time.
For example, if the imaging processing unit 14 receives a special effect input signal associated with a slow motion recording operation, which represents a slow down or slow motion displaying at −2× the native frame rate. Upon which, the raw frames 22 are processed using algorithm wherein every frame is duplicated/repeated, as best illustrated in FIG. 3D. Raw frame #1 can be appended in writer, then raw frame #1 is duplicated and written, then raw frame #2 is written, then raw frame #2 is duplicated and written, then raw frame #3 is written, and then raw frame #3 is duplicated and written, and so on until a modified or output video recording data 24 is generated in −2× slow motion speed. This process is conducted in real time, and the slow motion output video is recorded in place of the raw video data 22, and/or displayed in real time or immediately after recording has stopped and the post recording algorithm has completed processing the commands entered while recording.
In some embodiments, if the imaging processing unit 14 receives a special effect input signal associated with a slow motion recording operation, which represents a slow down or slow motion displaying at −3× the native frame rate, then the imaging processing unit 14 appropriately modifies the raw video data 22. Upon which, the raw frames are processed using algorithm wherein every frame is duplicated/repeated at least twice, as best illustrated in FIG. 3E. Raw frame #1 can be appended in writer, then raw frame #1 is duplicated twice and each is written, then raw frame #2 is written, then raw frame #2 is duplicated twice and each is written, then raw frame #3 is written, and then raw frame #3 is duplicated twice and each written, and so on until a modified or output video recording data 24 is generated in −3× slow motion speed. This process is conducted in real time, and the slow motion output video is recorded.
In some embodiments, if the imaging processing unit 14 receives a special effect input signal associated with a slow motion recording operation, which represents a slow down or slow motion displaying at −2× the native frame rate. Upon which, the raw frames 22 are processed using algorithm wherein new frames are created as a result of “blending” of two adjacent frames, as best illustrated in FIG. 3F. Raw frame #1 can be appended in writer, then raw frame #1 is “blended” with raw frame #2 to create 1 new frame, #1a, and then #1a is written, then raw frame #2 is written, then raw frame #2 is “blended” with raw frame #3 to create 1 new frame, #2a, and then #2a is written, then raw frame #3 is written, then raw frame #3 is “blended” with raw frame #4 to create 1 new frame, #3a, and then #3a is written, and so on until a modified or output video recording data 24 is generated in −2× slow motion speed. This process is conducted in real time, and the slow motion output video is recorded in place of the raw video data 22, and/or displayed in real time or immediately after recording has stopped and the post recording algorithm has completed processing the commands entered while recording.

Referring now in more to methods for controlling a special effects operation of live video capturing data in real time. As outline, in some embodiments, the methods comprise capturing a video of real world scene with the camera; playing at normal speed on a graphical user interface the video being captured; changing the playing speed on the graphical user interface of the video being recorded from the normal playing speed to a modified playing speed in response to a user interface input received by the graphical user interface. Reference will now be made in more detail to specific processes according to some embodiments for controlling special effects operations of live video capturing data in real time.
A possible process of the software application or interface is illustrated in FIGS. 6, 7 and 24. The interface and/or software application allows the user to select a predefined video recording speed rate in real time, without altering the raw speed rate provided by the camera. This makes the present technology not camera or device dependent. FIG. 6 illustrates an overall process of the present technology including the user interface, the device, and the subroutines associated with the overall process.
Referring to FIG. 7, the process of the present technology is described which determines if any special effects option has been requested for raw video data stream from the camera. For exemplary purposes, the special effects can be the changing of video speed rate by modifying of frames in the raw video data. The process can be configured or configurable to initiate subroutines and/or subprocesses to assist in the overall process.
The present technology software application is initiated and the user interface is provided to the user. An initial step can be for the user to opens the App 50. After which, step 51 allows the user to go into Camera Settings and selects either to use the electronic device's camera or a remote video feed. The process then proceeds to step 52 wherein the user starts the recording process. The camera or electronic device receives a “start” command 53 to initiate audio/video recording. It can be appreciated that the camera “start” command can be initiated by the present technology software application, a camera application, any other application associated with the electronic device or with a remote device in communication with the electronic device or camera.
Step 54 in the process can be to determine if the user has appropriate permission to proceed with the process. At step 56, permission attributes can be obtained from separate user settings, profiles, databases, keys, accounts, and the like. The permission attributes can be obtained from a user database 58.
Step 60 determines if the user has the appropriate permission, and if the user does not have the appropriate permission, then the process is stopped or ends (step 94). If the user does have appropriate permission then the process proceeds to step 62, which will get the device's supported settings, including a maximum recording frame rate frames per second (fps). Then the process sets the local or remote device's recording fps based on user permission and device support in step 64, and then opens an input stream from the device in step 66.
Once the raw data input stream from the camera is communicated to the image processing unit, then the process will then determine if the video data stream from the camera is opened in step 68, while receiving information from step 62. This request can be utilized to check if image processing unit is receiving the raw video data from the camera. The raw video data stream may include an integral or peripheral microphone, and can be passed to the image processing unit and not to the memory unit or video recording device. If the process determines that the input stream is not opened, then the process is stopped or ends (step 94).
If the input stream is open, then the process proceeds to step 70 to determine if the raw video data should be saved/recorded. If the raw video data is to be saved, then the process proceeds to step 72 to initiate a new parallel process utilizing the write video stream subroutine as illustrated in instance 1 in FIG. 8. Additional input data from the recording device (step 74) can be saved with the raw video data.
If it was determined in step 70 that the raw video data is not to be saved, then process proceeds to step 76 to determine if while the video input stream is open, and if it is open then the process proceeds to step 76 to determine if a special effect command has been entered by the user (step 82). The special effect command can be entered in this process by way of the interface. If the user entered a special effect command, then step 84 is initiated to apply a special effect subroutine, as best illustrated in FIG. 9. Additional input data from the recording device (step 86) can be included with the application of special effects in step 84.
If the user has not entered a request for a special effect in step 82, such as a change in video speed rate, then step 88 is initialized which applies other commands, such as input data from the recording device (step 90) and/or input processed video and audio data with special effects (step 92). Step 88 can include other information from step 84.
If the video input stream is determined to be closed in step 76, then the process proceeds stops or ends (step 94).
If necessary, step 78 can initiate a new parallel process utilizing the write video stream subroutine as illustrated in instance 2 in FIG. 8. Additional processed video and audio data (step 80) can be saved with the video data from step 78. The new parallel process of step 78 can be initiated separately and independently from steps 84 and/or 88. After step 78 the process proceeds back to step 76.
This process can write the raw video stream using the write video stream subroutine after the raw video data stream has been either processed using apply special effect subroutine or has retained the raw video data stream.
Referring to FIG. 8, the write video stream subroutine is describe which provides the process to write/save/record the video data stream to one or more internal memory, to one or more removable memory in communication with the electronic device, to one or more external devices, and/or to upload to one or more cloud devices or accounts.
The present technology process determines in sequence which device or devices is the video data stream to be written to, and if the user has appropriate permission for each of the steps associated with the write video stream subroutine. If the user does have the appropriate permission to write to that particular device or devices, then the process writes the video data stream to that particular device or devices in accordance with any user preferences.
This subroutine starts (step 104) upon initiation by a command from the process in FIG. 7. This subroutine then proceeds to obtain user's preferences and permissions (step 102) from the process in FIG. 7 or a database (steps 104 and 106). After step 102, this subroutine acquires the raw video data stream from the camera as an input (step 108). The raw video data stream can be audio/video stream from the electronic device, the camera and/or the microphone, as per step 110 and/or audio/video stream from the device's RAM memory and/or non-volatile long term memory, as per step 112.
After acquisition of the raw video data stream, step 114 of this subroutine is initiated which determines if the user has permission to write to internal memory. If the user does have the appropriate permission and if the user preferences allows for a write/copy action to internal memory (step 116), then a new process is started at step 118 which writes the video data stream to the internal memory.
If the user does not have permission to write to the internal memory from step 114, or if the user preferences in step 116 do not allow the write/copy action in step 116, or after starting the process in step 118, then this subroutine continues to determine if the user has permission to write to removable memory (step 120). If the user does have the appropriate permission and if the user preferences allows for a write/copy action to removable memory (step 122), then a new process is started at step 124 which writes the video data stream to the removable memory.
If the user does not have permission to write to the removable memory from step 120, or if the user preferences in step 122 does not allow such an action, or after starting the process in step 124, then this subroutine continues to determine if the user has permission to write to external devices (step 126). If the user does have the appropriate permission and if the user preferences allows for a write/copy action to external devices (step 128) is requested, then a new process is started at step 130, which writes the video data stream to the external devices.
If the user does not have permission to write to the external devices from step 126, or if the user preferences in step 128 do not allow the write/copy action in step 128 does not allow such an action, or after starting the process in step 130 is completed, then this subroutine continues to determine if the user has permission to write to cloud (step 132). If the user does have the appropriate permission and if the user preferences allows for a write/copy action to the cloud (step 134), then a new process is started at step 136 which writes the video data stream to the cloud.
If the user does not have permission to write to the cloud from step 132, or if the user preferences from step 134 does not allow such an action, or after starting the process in step 136, then this subroutine stops or ends (step 138).
Referring to FIG. 9, the apply special effects subroutine is described which determines if a special effects option has been requested and to the specific operation of the special effects request. This subroutine starts (step 140) upon initiation by a command from the process in FIG. 7. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 142). The raw video data stream can be audio/video stream from the electronic device, the camera and/or the microphone, as per step 146.
After acquisition of the raw video data stream, step 148 is initiated, which determines if the current speed is equal to the normal or native speed, such as but limited to Recording_fps is greater than the Playback_fps. If the user has made a speed change request, then step 150 initiates an advanced slow motion subroutine, as best illustrated in FIG. 12. After the completion of step 150, this subroutine stops or ends (step 168).
If the user has not made a speed change request such that the new speed is not set to normal, such as if the Recording_fps is not greater than the Playback_fps or if the Recording_fps is equal to the Playback_fps, then this subroutine proceeds to step 152 which determines if the current speed is equal to the normal or native speed. If the user has made a speed change request or if user has set the speed back to normal from a previously modified speed setting, then this subroutine continues to step 154 to write video stream to RAM memory and/or non-volatile long term memory buffer, as per FIG. 3A. After step 154 is completed, the subroutine proceeds to step 164 to return video buffer (RAM memory and/or non-volatile long term memory) to a calling function, which can be as step to determine if the video stream is open or this subroutine stops or ends (step 168).
If the user has not made a speed change request such that the new speed is not set to normal, this subroutine will then proceed to step 156, which determines if the speed change request is faster or slower than the normal speed of the raw video data stream. This can be accomplished by determining if the current speed is greater than normal. If the current speed is greater than the normal spend, then this subroutine will initiate a speed up subroutine (step 158), as best illustrated in FIG. 10. After the speed up subroutine is completed, this subroutine will then initiate step 164 to return video buffer (RAM memory and/or non-volatile long term memory) to the calling function.
If the requested current speed is not greater than the normal speed, then this subroutine continues to step 160 to determine if the current speed is to be less than normal. If the current speed is less than the normal spend, then this subroutine will initiate a slow down subroutine (step 162), as best illustrated in FIG. 13. After the slow down subroutine is completed or if the current speed is not to be less than normal, then this subroutine will initiate step 164 to return video buffer (RAM memory and/or non-volatile long term memory) to the calling function.
Referring to FIG. 10, the speed up subroutine is described which determines if a frame dropping option and/or other plugins are required. This subroutine starts (step 170) upon initiation by a command from the apply special effects subroutine (FIG. 9, step 158). After starting, this subroutine acquires the raw video data stream from the camera and/or from streamed input from a remote video feed as an input (step 172). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 174.
After acquisition of the raw video data stream, step 176 of this subroutine is initiated which determines if the video data input stream from the camera is open. If it is not open then this subroutine proceeds to step 189, which stops or ends this subroutine.
If the input stream is open then this subroutine determines if frame dropping is required (step 178), and if required then continues to step 180 that initiates a frame dropping subroutine as best illustrated in FIG. 11.
If frame dropping is not required from step 178 or after the frame dropping subroutine of step 180 is completed, then this subroutine proceeds to step 181 to determine if the use of time compression or expansion is requested, and if required then continues to step 182 that initiates a time compression and expansion subprocess as best illustrated in FIG. 20.
If frame time compression and/or expansion is not required from step 181 or after the time compression and/or expansion subprocess of step 182 is completed, then this subroutine proceeds to step 183 to determine if the use of variable FPS playback is requested, and if required then continues to step 184 that initiates a variable FPS playback subprocess as best illustrated in FIG. 21.
If frame variable FPS playback is not required from step 183 or after the variable FPS playback subprocess of step 184 is completed, then this subroutine proceeds to step 185 to determine if other plugins or applications are requested.
In the case that other plugins or application is requested, then this subroutine proceeds to step 186 to execute the other plugins or applications and apply their functions to the raw video stream from step 178 or modified video stream from any of steps 180, 182 and/or 184. For example, other plugins or applications can be, but not limited to, smoothing technology and the like. These other plugins or applications can be integrated with the present technology software application, or can be remote from the present technology but accessible and operable with present technology software application.
In the case the user does not request the use of other plugins or applications from step 185 or after the other plugin process of step 186 is completed, then this subroutine will continue to step 188 to return data to a calling function that loops back to step 176 to determine if the video input stream is open. Step 188 can receive video/audio streams from RAM memory and/or non-volatile long term memory (step 187).
It can be appreciated that this apply special effects subroutine includes a looped subprocess including steps 178, 180, 185, 186 and 188 until the input stream is determined to not be open in step 176.
With reference to FIG. 11, the frame dropping subroutine is described which determines if and which frames are dropped to simulate the requested fast motion video. An exemplary case for this subroutine can be if the Record_fps is equal to the Playback_fps. This subroutine starts (step 190) upon initiation by a command from the speed up subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 192). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 194.
After acquisition of the raw video data stream, step 196 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 196 determines that the input stream is not open, then this subroutine proceeds to step 198, which returns data to a calling function being step 180 in FIG. 10. Step 198 can receive data of the video/audio frames from RAM memory and/or non-volatile long term memory (step 200). After the step 198 is completed, then this subroutine stops or ends (step 202).
While the input stream is open from step 196, this subroutine determines if the speed equals 2 times faster than normal (step 204). If so then step 206 is initialized which will drop the next frame, as per FIG. 3B. After which, this subroutine proceeds to step 220 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 220, this subroutine returns to step 196.
If the speed does not equal 2 times faster than normal (step 204), then this subroutine determines if the speed equals 3 times faster than normal (step 208). If so then step 210 is initialized which will drop the next 2 frames, as per FIG. 3C. After which, this subroutine proceeds to step 220 and then returns to step 196.
If the speed does not equal 3 times faster than normal (step 208), then this subroutine determines if the speed equals 4 times faster than normal (step 212). If so then step 214 is initialized which will drop the next 3 frames. After which, this subroutine proceeds to step 220 and then returns to step 196.
If the speed does not equal 4 times faster than normal (step 212), then this subroutine will sequentially continue to determine if the speed equals “n” times faster than normal (step 216). If so then each “nth” step will initialize a drop the next (n−1) frames action (step 218). After which, this subroutine proceeds to step 220 and then returns to step 196.
It can be appreciated that this frame dropping subroutine determines if a frame should or should not be dropped on a frame-by-frame basis. The result is a modified video stream with specific frames removed to simulate a fast motion video of predetermined speed. This modified video stream is then written/saved to memory in real time.
It can be appreciated that this frame dropping subroutine includes a looped subprocess including steps 204-220 until the input stream is determined to not be open in step 196.
Referring to FIG. 12, the advanced slow motion subroutine is described which determines if a frame adding option or other plugins are required. This subroutine starts (step 222) upon initiation by a command from the apply special effects subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 224). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 246.
After acquisition of the raw video data stream, step 248 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 248 determines that the input stream is not open, then this subroutine proceeds to step 270, which stops this subroutine.
While the input stream is open from step 248, this subroutine determines if frame adding is required (step 250), and if required then continues to step 252 that initiates a frame adding subroutine, as best illustrated in FIG. 13.
If frame adding is not required from step 250 or after the frame adding subroutine from step 252 is completed, then this subroutine proceeds to step 254 to determine if an increase in frames rate recording speed is required. If so, then this subroutine continues to step 256, which initiates a variable frame rate subroutine or an increase frame rate subroutine, as best illustrated in FIG. 14.
If increase in frames rate recording speed is not required from step 254 or after the variable frame rate subroutine from step 256 is completed, then this subroutine proceeds to step 258 to determine if a constant high frames rate recording speed is to be used. If so, then this subroutine proceeds to step 260, which initiates a constant high frame rate subroutine, as best illustrated in FIG. 15.
If frame constant high frames rate recording speed is not required from step 258 or after the constant high frames rate recording speed subroutine of step 260 is completed, then this subroutine proceeds to step 261 to determine if the use of time compression or expansion is requested, and if required then continues to step 262 that initiates a time compression and expansion subprocess as best illustrated in FIG. 20.
If frame time compression and/or expansion is not required from step 261 or after the time compression and/or expansion subprocess of step 262 is completed, then this subroutine proceeds to step 263 to determine if the use of variable FPS playback is requested, and if required then continues to step 264 that initiates a variable FPS playback subprocess as best illustrated in FIG. 22.
If frame variable FPS playback is not required from step 263 or after the variable FPS playback subprocess of step 264 is completed, then this subroutine proceeds to step 265 to determine if other special effects enhancement is requested. In the case that other special effects enhancement is requested, then this subroutine proceeds to step 267, which can execute the other special effects subroutine and apply their functions to the raw or modified video stream. This other special effects subroutine can be integrated with the present technology software application, or can be remote from the present technology but accessible and operable with present technology software application.
In the case the user does not request the use of other special effects enhancement from step 265 or after the other special effects subroutine from step 267 is completed, then this subroutine will continue to step 266 to return data to a calling function that loops back to step 248 to the determine if the video input stream is open. It can be appreciated that other processed audio/video data can be part of the data returned to the calling function, as per step 268.
It can be appreciated that this advanced slow motion subroutine includes a looped subprocess including steps 250-266 until the input stream is determined to not be open in step 248.
With reference to FIG. 13, the frame adding subroutine associated with the slow down subroutine of FIG. 12 is described which determines if and which frames are added to simulate the requested slow motion video. This subroutine assumes that recording fps=playback fps. This subroutine starts (step 272) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 274). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 276.
After acquisition of the raw video data stream, step 274 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 278 determines that the input stream is not open, then this subroutine proceeds to step 298, which returns data to a calling function being step 252 in FIG. 12. Step 298 can receive data of the video/audio frames from RAM memory and/or non-volatile long term memory (step 300). After step 298 is completed, then this subroutine stops or ends (step 302).
While the input stream is open from step 278, this subroutine determines the type of frame adding to utilize in step 280, either simple frame copying (step 281) or a more CPU intensive frame blending (step 282). If the user has selected frame copying, then the process proceeds to step 281 and the algorithm and its description are unchanged. However, if the user selected “Frame Blending” and their hardware supports it, then the process proceeds to step 282 and the algorithm can include new or additional steps.
It can be appreciated that if frame copying was selected during step 280 then for each of the speed “checks”, logically, the process will proceed along the left algorithm path. It can be further appreciated that if frame blending was selected during step 280 then for each of the speed “checks”, logically, the process will proceed along the right algorithm path.
The subroutine continues to determine if the speed equals 2 times slower than normal (step 283). If so, for the frame copying path, then step 284 is initialized which will copy the frame 1 time for a total of 2 of the identical frames, as per FIG. 3D. After which, this subroutine proceeds to step 296 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 296, this subroutine returns to step 278. For the frame blending path, then step 285 is initialized which will blend the current frame with the next frame for a total of 1 new “blended” frame, as per FIG. 3F. After which, this subroutine proceeds to step 296.
If the speed does not equal 2 times slower than normal (step 283), then this subroutine determines if the speed equals 3 times slower than normal (step 286). If so, for the frame copying path, then step 287 is initialized which will copy the frame 2 times for a total of 3 of the identical frames, as per FIG. 3E. After which, this subroutine proceeds to step 296 and then returns to step 278. For the frame blending path, then step 288 is initialized which will blend the current frame with the next frame for a total of 2 new “blended” frames, as per FIG. 3G. After which, this subroutine proceeds to step 296.
If the speed does not equal 3 times slower than normal (step 286), then this subroutine determines if the speed equals 4 times slower than normal (step 289). If so, for the frame copying path, then step 290 is initialized which will copy the frame 3 times for a total of 4 of the identical frames. After which, this subroutine proceeds to step 296 and then returns to step 278. For the frame blending path, then step 291 is initialized which will blend the current frame with the next frame for a total of 3 new “blended” frames. After which, this subroutine proceeds to step 296.
If the speed does not equal 4 times slower than normal (step 289), then this subroutine will continue to determine if the speed equals “n” times slower than normal (step 292). If so, for the frame copying path, then each “nth” step will copy the frame (n−1) times for a total of “n” of the identical frames. After which, this subroutine proceeds to step 296 and then returns to step 278. For the frame blending path, then step 295 is initialized which will blend the current frame with the next frame for a total of (n−1) new “blended” frames. After which, this subroutine proceeds to step 296.
It can be appreciated that this frame adding subroutine includes a looped subprocess including steps 280-296 until the input stream is determined to not be open in step 278.
With reference to FIG. 14, an example of the variable high recording fps subroutine (120 FPS) associated with the variable frame rate subroutine of FIG. 12 is described. This variable frame rate subroutine can be utilized for simulating slow motion, such as but limited to, slow motion range=recording speed/playback fps=120 fps/30 fps=4.
This subroutine starts (step 304) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 306). The raw video data stream can be audio/video stream from the electronic device, the camera and/or the microphone, as per step 308.
After acquisition of the raw video data stream, step 310 of this subroutine is initiated to set the device's recording frame rate, for example to Recording_Frame_Rate=120 fps. After which, step 312 sets the device's playback frame rate, for example to Playback_Frame_Rate=30 fps.
Step 314 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 314 determines that the input stream is not open, then this subroutine proceeds to step 332, which returns data to a calling function being step 256 in FIG. 12. Step 332 can receive data of the video/audio frames from RAM memory and/or non-volatile long term memory (step 334). After step 332 is completed, then this subroutine stops or ends (step 336).
While the input stream is open from step 314, this subroutine determines if the recording speed equals “−4×” (step 316), which can be a slow motion range of 4. If so then step 318 is initialized which sets the recording frame rate to 120 fps. After which, this subroutine proceeds to step 330 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 330, this subroutine returns to step 314.
If the recording speed does not equal “−4×” (step 316), then this subroutine determines if the recording speed equals “−3×” (step 320). If so then step 322 is initialized which sets the recording frame rate to 90 fps. After which, this subroutine proceeds to step 330 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 330, this subroutine returns to step 314.
If the recording speed does not equal “−3×” (step 320), then this subroutine determines if the recording speed equals “−2×” (step 324). If so then step 326 is initialized which sets the recording frame rate to 60 fps. After which, this subroutine proceeds to step 330 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 330, this subroutine returns to step 314.
If the recording speed does not equal “−2×” (step 324), then this subroutine will set the recording frame rate to 30 fps (step 328), which can be a recording speed equal to or less than “normal”. After which, this subroutine proceeds to step 330 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 330, this subroutine returns to step 314.
It can be appreciated that this variable high recording fps subroutine includes a looped subprocess including steps 316-330 until the input stream is determined to not be open in step 314.
With reference to FIG. 15, an example of the constant frame rate slow motion subroutine associated with the constant high frame rate subroutine of FIG. 12 is described. This constant frame rate slow motion subroutine can be utilized for simulating slow motion.
This subroutine starts (step 340) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 342). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 346.
After acquisition of the raw video data stream, step 348 of this subroutine is initiated which gets the video stream's recording frame rates (recording fps), and then continues to step 350 that gets the video stream's playback frame rates (playback fps).
With the recording and playback frame rates acquired, this subroutine then determines if the recording_fps=playback_fps*2 (step 352). If so, then it proceeds to step 354 to initiate a constant high frame rate subroutine at 60 fps, as best illustrated in FIG. 16. After which, this subroutine stops or ends (step 368).
If is not found that the recording_fps=playback_fps*2, then this subroutine proceeds to step 356 to determine if the recording_fps=playback_fps*4. If so, then it proceeds to step 358 to initiate a constant high frame rate subroutine at 120 fps, as best illustrated in FIG. 17. After which, this subroutine stops or ends (step 368).
If is not found that the recording_fps=playback_fps*4, then this subroutine proceeds to step 360 to determine if the recording_fps=playback_fps*8. If so, then it proceeds to step 362 to initiate a constant high frame rate subroutine at 240 fps, as best illustrated in FIG. 18. After which, this subroutine stops or ends (step 368).
If is not found that the recording_fps=playback_fps*8, then this subroutine proceeds to step 364, which is generic for all other cases and initiates a constant high frame rate subroutine at higher fps. After which, this subroutine stops or ends (step 368).
With reference to FIG. 16, an example of the constant high recording fps subroutine (60 FPS) associated with the constant high frame rate subroutine of FIG. 15 is described. This constant high frame rate subroutine can be utilized for simulating slow motion, such as but limited to, slow motion range=recording speed/playback fps=60 fps/30 fps=2. “Slow motion range” is defined as the multiple factor that a slow motion effect can be created with the record and playback fps settings such that the algorithm does not have to use “frame adding” of any type.
This subroutine starts (step 370) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 372). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 374.
After acquisition of the raw video data stream, step 376 of this subroutine is initiated which set the device's recording frame rate, for example to Recording_Frame_Rate=60 fps. After which, step 378 sets the device's playback frame rate, for example to Playback_Frame_Rate=30 fps.
Step 380 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 380 determines that the input stream is not open, then this subroutine proceeds to step 398, which returns data to a calling function being step 354 in FIG. 15. Step 398 can receive data of the video/audio frames from RAM memory and/or non-volatile long term memory (step 400). After step 398 is completed, then this subroutine stops or ends (step 402).
While the input stream is open from step 380, this subroutine determines if the recording speed equals “−4×” (step 382). If so then step 384 is initialized which copies each frame in the stream 2 times for a total 3 identical frames as per FIG. 3E or blended frames as per FIG. 3G. After which, this subroutine proceeds to step 396 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 396, this subroutine returns to step 380.
If the recording speed does not equal “−4×” (step 382), then this subroutine determines if the recording speed equals “−3×” (step 386). If so then step 388 is initialized which copies each frame in the stream 1 time for a total 2 identical frames as per FIG. 3D or blended frames as per FIG. 3F. After which, this subroutine proceeds to step 396 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 396, this subroutine returns to step 380.
If the recording speed does not equal “−3×” (step 386), then this subroutine determines if the recording speed equals “−2×” (step 390). If so then step 392 is initialized which passes thru an unchanged video stream. After which, this subroutine proceeds to step 396 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 396, this subroutine returns to step 380.
If the recording speed does not equal “−2×” (step 390), then this subroutine will drop 1 of 2 frames (1/2) (step 394) for a recording speed equal to “normal”. After which, this subroutine proceeds to step 396 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 396, this subroutine returns to step 380.
It can be appreciated that this constant high recording fps subroutine (60 FPS) includes a looped subprocess including steps 382-396 until the input stream is determined to not be open in step 380.
With reference to FIG. 17, an example of the constant high recording fps subroutine (120 FPS) associated with the constant high frame rate subroutine of FIG. 15 is described. This constant high frame rate subroutine can be utilized for simulating slow motion, such as but limited to, slow motion range=recording speed/playback fps=120 fps/30 fps=4.
This subroutine starts (step 404) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the camera as an input (step 406). The raw video data stream can be audio/video stream from the local electronic device including the camera and/or microphone, from a remote device including the camera and/or the microphone, or from other audio/video feeds, as per step 408.
After acquisition of the raw video data stream, step 410 of this subroutine is initiated which sets the device's recording frame rate, for example to Recording_Frame_Rate=120 fps. After which, step 412 sets the device's playback frame rate, for example to Playback_Frame_Rate=30 fps.
Step 414 of this subroutine is initiated which determines if the video data input stream from the camera is open. If step 414 determines that the input stream is not open, then this subroutine proceeds to step 448, which returns data to a calling function being step 358 in FIG. 15. Step 448 can receive data of the video/audio frames from RAM memory and/or non-volatile long term memory (step 450). After step 448 is completed, then this subroutine stops or ends (step 452).
While the input stream is open from step 414, this subroutine determines if the recording speed equals “−8×” (step 416). If so then step 418 is initialized which copies the frame 4 times for a total 5 identical frames or blended frames. After which, this subroutine proceeds to step 446 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 446, this subroutine returns to step 414.
If the recording speed does not equal “−8×” (step 416), then this subroutine determines if the recording speed equals “−7×” (step 420). If so then step 422 is initialized which copies the frame 3 times for a total 4 identical frames or blended frames. After which, this subroutine proceeds to step 446 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 446, this subroutine returns to step 414.
If the recording speed does not equal “−7×” (step 420), then this subroutine determines if the recording speed equals “−6×” (step 424).

With reference to FIG. 23, an example of a variable playback speed playback subroutine is illustrated and will be described, which provides a flow chart algorithm for playing a video file with slow motion and fast motion special effects by speeding up or slowing down the playback frame rate while video playback is in progress. An application employing the algorithm in FIG. 23 is required to play a video produced by the algorithm in FIGS. 20 and 21. This application must be capable of decoding the information in the metadata and/or an accompanying “video project file” and applying the speed up and slow down commands to the playback frame rate while the video is playing. A video project contains the video file plus an accompanying file that has the special effects commands to be executed, that a custom player can decode and apply in real-time playback.
If the video is played with an incompatible player, then the speed up and slow down special effects commands in the metadata are ignored and the video plays continuously in the same speed.
This subroutine starts (step 622) upon initiation by a command from the slow down subroutine. After starting, this subroutine acquires the raw video data stream from the video project file residing in device's memory as an input (step 624).

If so then step 340 is initialized which sets the segment playback fps to equal the recording fps for that video section (Segment FPS=Record_FPS). After which, this subroutine proceeds to step 646 to write frame(s) to buffer (RAM memory and/or non-volatile long term memory). After step 646, this subroutine returns to step 632.

A possible method of using the present technology is illustrated in FIG. 24. A user can launch an application software (App) on a device capable of running the App, utilizing a user interface of the present technology. The App can open in an image composition screen, which can be as a default setting. Favorite or predetermined settings can optionally be selectable by the user. Device settings are applied and the device is in a ready state, while optionally still in the image composition screen.
The user can the start recording, utilizing the device's camera, a remote camera or a remote video stream, by touching or activating a “Record” icon associated with the App or user interface. Optionally, the user can touch and hold the Record icon or button continuously to continue recording. One aspect can be that the icon or a button associated with the icon can be animated to indicate a live recording is active.
While the recording is in progress, the user can enter special effect commands being to zoom in or zoom out. The video being displayed by the device is configured or configurable to show the zooming in or out special effect associated with the video in real time.
While the recording is in progress, the user can enter special effect commands being to create slow motion and/or fast motion. One aspect is that there is no difference in the speed of the display of the live video on the device.
The user can end recording by releasing or removing the touching of the Record icon or button. After which, the App stops recording, displays a “Review” screen, completes processing the special effect, and provides an option to save or autosave the processed video.
After saving, the newly produced video can be viewed by the device or a remote device after the processing has been completed. The video can play continuously and restart after ending. The App can provide a suite of editing tools that can be utilized to further edit or modify the raw or processed video. Optionally, the video can be edited to fine tune the slow motion and fast motion effects, along with other custom design elements, and post the video. This process can be repeated until a desired video result is created.
The App completes processing any new elements in the video and play back to the user after each edit is completed. This process can be repeated until a desired video result is created.
After processing the video and/or any additional editing to the video is complete, the App can save a final video or edit. The App can save the final video to the device's internal memory, to an external memory and/or to the cloud.
The App can further provide an option allowing the user to post the final video to social media platform. The App can upload the final video onto additional platforms and/or clouds, and display the composition screen allowing the user to start recording a new video.
With reference to FIG. 25, at least a portion of the interface 30 is described. The interface 30 can be, but not limited to, a GUI interface capable of providing a screen for device optimized parameters or variables. The GUI 30 can be configured or configurable to include a recording start/stop control 32 provided anywhere on the screen, and a speed selection region 34 provided anywhere on the screen that can provide a default or predefined frame rate speed that is used to manipulate the frame in the raw video data from the camera 12. The speed selection region 34 can include a speed control indicator 35 that can travel along the speed selection region 34 via control by the user to indicate the current or selectable speed. The GUI interface 30 can also include regions anywhere on the screen for controlling zoom 36, zoom and fast motion speed rate 38, and/or zoom and slow motion speed rate 40.
In some embodiment, a user can touch and/or hold the start/stop control 32 to initiate, stop or pause the recording function of the camera. Additionally, a user can interact with the speed selection region 34 by touching the region with a finger or stylus-like device, and making a sliding motion along the region in any direction. The processing unit can be configured or configurable to interpret this sliding movement as a special effect input command. For example, sliding from a central area of the speed selection region 34 toward the right could change the speed rate from the native speed rate to 2×, 3×, 4×, “n”× the native speed rate, depending on how far right the sliding motion travels on the speed selection region 34. Sliding from the central area of the speed selection region 34 toward the left could change the speed rate from the native speed rate to −2×, −3×, −4×, −“n”× the native speed rate, depending on how far left the sliding motion travels on the speed selection region 34.
In some embodiments, a user could control the zoom function of the camera by making a vertical sliding motion from a lower region of the GUI toward an upper region. A user could further control a combination of zoom and speed rate by making a curving vertical sliding motion from a lower region of the GUI toward an upper right or left region, depending if a zoom and fast motion or slow motion effect is desired.
Alternatively, the GUI interface 30 can be configured or configurable to include areas, icons or windows where functions, attributes, operations, settings and/or characteristics of the camera and/or display can be controlled. Examples of these functions, attributes, operations, settings and/or characteristics can be, but not limited to, flash, hands free, timer, mute, selfie, broadcast, sharing, filters, media, stop/start recording, and the like. The GUI interface 30 can be configured or configurable to be used to preset a minimum, a maximum or a range of the speed rate of the raw video.
Still further and optionally, the GUI interface 30 can be configured or configurable to include areas, icons or windows providing editing options to the video data stream. The editing options can include, but not limited to, adding text, adding drawings, adding sounds, face filters, adding decorations, creating a video loop, adding a cover, and the like.
The GUI interface 30 can be configured or configurable to include a display of the output video recording data, which can be the raw video data and/or the modified video data, or the edited video data stream can be displayed. It can be appreciated that the output video recording data displayed by the GUI interface 30 can be dynamically changing in real time due to changes in the input. Thus, the present technology can display, in real time, a seamless transition between the raw video data, any number of the modified video data or subsets thereof, while the camera acquires the video and while recording is in progress. The modified video data can include any number of fast to slow motion subsets, and these subsets can be in combination with subsets of the raw video data. The displaying of the raw video data and/or any number of modified video data is accomplished live or in real time as the camera is capturing images associated with the raw video data. It can be appreciated that the present technology renders the displayed output video data as the camera captures the images and while the output video is written to memory. Consequently, allowing the user to move, pan, zoom, etc. the camera while still capturing the video and at the same time applying and displaying any number of special effects to the raw video data.
In some embodiments, the user of the device implementing the present technology and GUI 30 is able to access operational functions of the present technology and/or device and/or camera and/or saved video by entering login credentials associated with a user account.
FIG. 26 illustrates an embodiment of the GUI 30 of the present technology utilized on an electronic device displaying an implementation of GUI of the present technology on a touch screen. FIG. 26 is an exemplary “Camera View” of the device employing the GUI 30 while recording in normal “1×” speed. In this normal speed setting, the raw video stream from the camera is not changed and displayed in real time in the GUI 30.
In some embodiments, the screen shot contains a number of icons representing various functions or affordances that the user can select. These affordances change icons as different “states” settings are selected for each affordance by the user. These affordances can be, but not limited to: a “Flash” affordance 700, which when activated (e.g. via a tap gesture), enables the user of the device to select a flash or light of the device to be on, off or automatically activated depending on light levels detected by or inputted into the device implementing the present technology; a “Hands Free” affordance 702, which when activated (e.g. via a tap gesture), enables the user of the device to control aspects of the present technology utilizing gestures on the device, remote control units, speech recognition, and/or a preprogrammed sequence or scheme so that the user can initiate continuously recording without requiring the user to constantly touch with the device (A “Hands-On” mode means the user must touch the record button continuously to continue recording. Once the user releases the record button, recording stops); a “Timer” affordance 704, which when activated (e.g. via a tap gesture), enables the user of the device to start and/or stop recording at a predetermined time(s) of day and/or for a predetermined time duration(s); a “Mute” affordance 706, which when activated (e.g. via a tap gesture), enables the user of the device to mute or deactivate a microphone associated with the device and/or camera; a “Selfie” or “Rear” affordance 708, which when activated (e.g. via a tap gesture), enables the user of the device to switch to a rearward facing or secondary camera associated with the device implementing the present technology; a “Setting” affordance 710, which when activated (e.g. via a tap gesture), enables the user of the device to control operational settings of the GUI, device and/or camera; a “Go Live” affordance 712, which when activated (e.g. via a tap gesture), enables the user of the device to transmit the video feed from the present technology to a remote device or server; a “Friend” affordance 714, which when activated (e.g. via a tap gesture), enables the user of the device to search and/or invite friends or contacts to make a social connection; a “Media” affordance 716, which when activated (e.g. via a tap gesture), opens a media folder that enables the user of the device to open and load videos from a folder created in memory of the device or a remote device or a cloud storage; a “Face Filters” affordance 718, which when activated (e.g. via a tap gesture), enables the user of the device to initiate a subprocess or a third-party application that applies filtering with “Augmented Reality” (AR) functions to the video; a “Scene Filters” affordance 720, which when activated (e.g. via a tap gesture), enables the user of the device to initiate a subprocess or a third-party application that applies filtering functions to the video; and/or an “Upgrades” affordance 722, which when activated (e.g. via a tap gesture), enables the user of the device to upgrade aspects of the present technology and/or memory storage. It can be appreciated that additional icons, functions or affordances can be implemented with or on the GUI. Any number of the icons or affordances 700-722 can be positioned or positionable in predetermined or customizable locations in the GUI 30.
The recording start/stop control 32 can be provided as a button anywhere on the screen that allows the user to start, stop and/or pause the recording of video (e.g. via a tap or touch holding gesture), and the speed selection region which can be a slide bar 34 can be provided anywhere on the screen as a slide bar with circles and/or other shapes and markers indicating selectable playback speeds of the portion of the video in playback. The slide bar 34 enables the user to control the special effects aspect of the video (e.g. via a sliding gesture). The current speed indicator in FIG. 26 is set at “1×” indicating the record speed is “normal”. This speed factor is inputted into step 82 of the process illustrated in FIG. 7. In this example, since the user has not entered a special effects command (speed factor “1×” or “normal”), then the process would proceed to step 88, dependent in part of preceding steps.
If the user activated any of the additional operation functions 700-722, then these inputs are determined by step 88, and the appropriate or corresponding parallel processes are initiated in step 78. The record button 32, the speed selection button 35, the speed selection region 34, the zoom level indicator/controller 748, and any icons can be activated utilizing the touchscreen of the user device.
In FIG. 26, the video feed displayed in a first region of the GUI 30 is a live video feed from the respective camera or a remote video feed. Any editing or modified video stream from any initiated operation functions 700-722 can be displayed in one or more additional regions of the GUI 30. These display regions in the GUI 30 can be separate and independent regions, can in part overlap, or can be overlaid. In some implementations, the video feed displayed in any of the regions may be previously recorded video footage. In other implementations, the video displayed in any of the regions of the GUI 30 can be, for example, any position on an event timeline associated with the displayed video feed. The timeline can be manipulated by the user by sliding a timeline bar causing the present technology to display the video feed from that point in time forward in any of the regions.
Additionally, the raw video stream and/or editing video stream can be saved to an appropriate memory indicated by the user using the GUI 30. The memory or memory devices selected by the user using the GUI 30 is inputted into the write video stream subroutine in FIG. 8 and the video stream(s) are written or copied appropriately.
FIG. 27 illustrates an exemplary embodiment “Camera View” of the electronic device employing the GUI 30 of the present technology while recording in slow motion “−2×” speed. In this slow motion speed setting, the frame adding subroutine is utilized and the apparent playback speed is twice as slow as a normal video. In the “Hands-Free” mode example, the user can tap a desired speed marker or slide an indicator to a desired speed marker located on the speed selection region 34. In “Hands-On” mode, the user can press and hold the “Record” button 32 and slide his finger to the left and the button follows directly under the user's finger, so that the button is vertically above the “−2×” affordance label in this example. It can be appreciated that the speed marker 35 can automatically move along the speed selection region 34 to follow the movement of the “Record” button 32.
In some embodiments, a window 724 can be implemented in the GUI 30 that displays the raw video stream, while a majority of the GUI 30 displays the slow motion video stream. In the alternative, it can be appreciated that the window 724 can display the slow motion video stream, while the majority of the GUI 30 displays the raw video stream. In another alternative, it can be appreciated that the window 724 can display the slow motion video stream or a still frame “cover” image of the video stream, while the majority of the GUI 30 displays the live video stream.
The current speed indicator in FIG. 27 is set at “−2×” indicating the record speed is slow motion. This speed factor is inputted into step 82 of the process illustrated in FIG. 7. In this example, the user has entered a special effects command (speed factor “−2×” or “slow motion”), then the process would proceed to step 84 wherein the process would initiate the special effects subroutine in FIG. 9.
If the user activated any of the additional operation functions 700-722, then these inputs are determined and the appropriate or corresponding parallel processes are initiated in step 78.
With the speed factor set to “−2×” using the GUI 30, the apply special effects subroutine is initiated which determines if the input from the GUI 30 represents a fast motion command (step 156 in FIG. 9) or a slow motion command (step 160 in FIG. 9), or go to advanced slow motion subroutine command (step 150 in FIG. 9). The process then initiates the appropriate subroutines corresponding to the input by the user on the slide bar 34. In this example, the frame adding subroutine illustrated in FIG. 13 would be initiated.
As the raw video stream is modified per the initiated subroutine, the GUI 30 displays in real time the resultant slow motion video via the device's display. The raw video stream can also be displayed via the GUI 30, in conjunction with the resultant slow motion video. Additionally, the resultant slow motion video and/or the raw video stream can be saved to an appropriate memory indicated by the user using the GUI 30. The memory or memory devices selected by the user using the GUI 30 is inputted into the write video stream subroutine in FIG. 8 and the video stream(s) are written or copied appropriately.
FIG. 28 illustrates an exemplary embodiment “Camera View” of the device employing the GUI 30 of the present technology while recording in fast motion “3×” speed. In this fast motion speed setting, the frame dropping subroutine or time compression subroutines is utilized and the apparent playback speed is three times as fast as a normal video without frame dropping. In this example, a “Hands-Free” mode can be utilized where the user can tap a desired speed marker or slide an indicator to a desired speed marker located on the speed selection region 34. In a “Hands-On” mode, the user can press and hold the record button 32 to record continuously and slide his finger left and right to indicate desired speed and the speed marker 35 located on the speed selection region 34 moves accordingly.
In some embodiments, the user can utilize a “One-Touch” mode to manipulate the video's time. In this mode, recording operation can be initiated by touching the screen, and taking a finger off the screen will stop recording operation. Alternatively, recording is in operation while touching the screen. Exemplary operation can include: moving the touching finger to the left of a middle of the screen will slow down video's time; moving the touching finger to the middle of screen returns video's time to normal speed; moving the touching finger to the right left of the middle of the screen will speed up video's time; the touching finger can quickly go from extreme left to extreme right (and vice-versa); moving the touching finger up will initiate a zoom in (telephoto) operation; moving the touching finger down will initiate a zoom out (wide angle) operation; and adjusting other settings separately live, such as but not limited to, flash 700, mute 706, etc., with other finger while recording is in progress and while the touching finger is on the screen.
Still further, some embodiments can include a “Multiple Touch” mode that allows the user to individually select functions through user interface whilst video is being recorded is shown in the user interface.
In some embodiments, the window 724 can be implemented in the GUI 30 that displays the raw video stream, while the majority of the GUI 30 displays the fast motion video stream. In the alternative, it can be appreciated that the window 724 can display the fast motion video stream, while the majority of the GUI 30 displays the raw video stream. In another alternative, it can be appreciated that the window 724 can display the fast motion video stream, while the majority of the GUI 30 displays the live video stream. In another alternative, it can be appreciated that the window 724 can display the still frame “cover image” for the fast motion video stream, while the majority of the GUI 30 displays the live video stream.
The current speed indicator in FIG. 28 is set at “3×” indicating the record speed is fast motion. This speed factor is inputted into step 82 of the process illustrated in FIG. 7. In this example, the user has entered a special effects command (speed factor “3×” or “fast motion”), then the process would proceed to step 84 wherein the process would initiate the special effects subroutine in FIG. 9.
If the user activated any of the additional operation functions 700-722, then these inputs are determined and the appropriate or corresponding parallel processes are initiated in step 78.
With the speed factor set to “3×” using the GUI 30, the apply special effects subroutine is initiated which determines if record fps=playback fps and if the input from the GUI 30 represents a fast motion command (step 156 in FIG. 9) or a slow motion command (step 160 in FIG. 9). The process then initiates the appropriate subroutines corresponding to the input by the user on the slide bar 34. In this example, the speed up subroutine illustrated in FIG. 10 would be initiated. If record fps>playback fps and if the input from the GUI 30 represents a fast motion command or a slow motion command, the process then initiates the appropriate subroutines corresponding to the input by the user on the slide bar 34. In this case, the speed up subroutine illustrated in FIG. 12, step 262 initiates subroutine illustrated in FIG. 20.
As the raw video stream is modified per the initiated subroutine, the GUI 30 displays in real time the resultant fast motion video via the device's display. The raw video stream can also be displayed via the GUI 30, in conjunction with the resultant slow motion video. Additionally, the resultant fast motion video and/or the raw video stream can be saved to an appropriate memory indicated by the user using the GUI 30. The memory or memory devices selected by the user using the GUI 30 is inputted into the write video stream subroutine in FIG. 8 and the video stream(s) are written or copied appropriately.
FIG. 29 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the user has stopped recording and the system displays a review screen for the user to review and edit the captured video. The GUI can highlight the icons by removing the background image example.
In some embodiments, the review screen can contain a number of icons representing various functions or affordances that the user can select. These icons, functions or affordances can be, but not limited to: a “Display Cover” affordance 726 which displays the still frame “cover image” of the video, a “Text” affordance 728, which when activated (e.g. via a tap gesture), enables the user of the device to add text to the video; a “Draw” affordance 730, which when activated (e.g. via a tap gesture), enables the user of the device to add images, clipart's and/or draw to the video; a “Sound” affordance 732, which when activated (e.g. via a tap gesture), enables the user of the device to add sound or music to the video; the “Face Filter” affordance 718; a “Decor” affordance 734, which when activated (e.g. via a tap gesture), enables the user of the device to add decorations such as stickers and emoji's to the video; a “Loop” affordance 736, which when activated (e.g. via a tap gesture), enables the user of the device to create loop sequence of a selected segment of the video; a “Cover” affordance 738, which when activated (e.g. via a tap gesture), enables the user of the device to use a frame or segment of the video as a cover page for the video a “Tag” affordance 739, which when (e.g. via a tap gesture), enables the user of the device to identify and tag other users who may nor may not appear in the video, and add “hashtags” for search engine optimization; a Media” affordance 716 which when activated (e.g. via a tap gesture), enables the user of the device to save the video to a folder on the device or in the cloud; a “Notes” affordance 740, which when activated (e.g. via a tap gesture), enables the user of the device to save the video to a “Notes” folder or application associated with the device; a “Project” affordance, which when activated (e.g. via long press “a touch and hold” gesture on the “Notes” affordance), enables the user of the device to save the video to a “Projects” folder or application associated with the device for collaboration between other users; a “Chat” affordance 742, which when activated (e.g. via a tap gesture), enables the user of the device to send the video to a contact or friend; a “Feed” affordance 744, which when activated (e.g. via a tap gesture), enables the user of the device to post the video to the user's channel's timeline in the social media aspect of the app, which can also be configured to post to the user's Web or RSS feed; and/or a “Story” affordance 746, which when activated (e.g. via a tap gesture), enables the user of the device to post the video to the user's story or social media page within the app or shared externally to other social media apps like Instagram®, Facebook®, Twitter®, etc. In some embodiments, when the Notes affordance 740 is pressed, a list of icons or “Projects” folders appear, each representing an available project the user can post the video to.
For example, the user can add decorations in the video, as well as set other properties for social media upload into the cloud. The user can elect to save the videos in the user's “Media” folder, save to the user's “Notes” location, save to the user's “Projects” location, send the video to a “Chat” contact or group, post to their “Feed”, or post to their “Story”. The system saves the story and takes appropriate action, utilizing any one of the subroutines and/or subprocesses associated with the present technology.
FIG. 30 illustrates an exemplary embodiment “Screen Shot” of FIG. 29 where the user has stopped recording and the system displays the review screen for the user to review the captured video. It can be appreciated that multiple windows 724 can be utilized, each displaying a different edited video stream or still frame cover image of the edited video stream.
FIG. 31 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays a composition screen before recording has started. The speed range can be displayed from “−3×” to “3×” normal speed, but additional speeds and ranges can be utilized and displayed.
In some embodiments, the composition screen can include a zoom setting region 748, which can control a zoom function of the camera (e.g. via a sliding and/or tap gesture or pinch-to-zoom). The zoom setting region 748 can be a zoom slid bar having an indicator moveable by the user by way of touching and sliding the indicator to a desired zoom operation. For example, the zoom slid bar 748 can be a vertically orientated slide bar located on the left or right side of the GUI 30. It can be appreciated that any gesture interface can be utilized in place of the exemplary slide bar. As the user slides his finger from top to bottom and back on the zoom slide bar 748, the “zoom factor” adjusts zoom in and zoom out accordingly as illustrated. In another example, using the “pinch-to-zoom”, the user uses a multi-touch gesture to quickly zoom in and out, while the “zoom factor” adjusts up and down accordingly.
The record button 32 can be located in a lower middle section of the GUI, with the “time speed” side bar 34 located therebelow. It is appreciated that the GUI 30 is not limited to specific locations of the record button 32, speed slide bar 34 and any of the icons as illustrated herewith. The record button 32, speed slide bar 34 and any of the icons can be located anywhere in the GUI, and can also be reconfigured, sized and/or moved by the user. For example, the user can provide a touch and hold gesture to any of the affordances, which thus enables the user to move or resize that selected affordance.
In FIG. 31, the user has tapped the “1×” speed marker or slid the indicated to the “1×” speed marker, which means the raw video is being displayed at normal speed with no special effects. It can be appreciated that the indicator “1×” can be substituted with other speed indicators such as, but not limited to, “Normal”.
The user can selectively set the location of the record button 32 before recording commences, to set the zoom 748 and the speed factors 34 for the device once recording starts. As the user move the moveable record button, the zoom and speed factors move accordingly. As the user slides his finger side to side on the speed slide bar 34, the “time speed” adjust faster or slower accordingly as illustrated.
FIG. 32 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays a recording screen while recording has started. In this example, the zoom factor is set to zero “0”, and the speed factor is set to fast motion “2×” being two times faster than normal speed.
In some embodiments, while the recording operation is active, the present technology can enlarge the record button 32 to be visible even underneath the user's finger. A radial progressive bar can be utilized with the record button 32 to indicate recording has started and/or a time duration of the recording. The record button 32 can be colored inside to assist in viewing by the user, and it can be appreciated that the size, configuration and/or color of the record button 32 can be configurable by the user.
In the alternative, the record button 32 can be moved to a location adjacent to the selected speed factor (e.g. via a touch holding gesture). In this present example, above the highlighted “2×” in the “speed scale” 34. The record button 32 can be configurable to follow the user's finger movements as long as the user is touching the screen.
The selected recording FPS, playback FPS and/or speed factor can be displayed in the GUI, as illustrated by the indicator “240 I--I--” and “Fast 2X” 750 in the center near the top of the GUI. The FPS and/or speed factor indicator can be animated or blinking prominently to alert the user of the FPS and/or recording speed. In another embodiment, the indicator 750 is the maximum time length for the video segment.
In some embodiments, the GUI 30 can also include “speed guidelines” 752 utilized and displayed vertically in dashed lines. The guidelines 752 are configured or configurable to guide the user's finger or pointing device to indicate when the user's touch point is approaching and then crossing the boundary for speed change.
Upon the user sliding or tapping to the desired speed factor, the application program of the present technology initiates the appropriate subroutine and/or necessary algorithm to create the fast or slow motion special effect associated with the selected speed factor received by the GUI.
FIG. 33 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays a “Slow Motion Resolution” settings screen. In this example, the slow motion resolution is the slow motion factor supported by hardware, without frame adding.
In some embodiments, the GUI 30 can include a scrollable selection 754 of multiple speed factor values. The selectable speed factor values in scrollable selection 754 (e.g. via a slide gesture) are the settings for the maximum video quality that the device supports. The selected speed factor can be highlighted to indicated which speed factor selected.
FIG. 34 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays an alternative advanced “Slow Motion Resolution” settings screen. In this example, the GUI 30 can display and utilize multiple slide bars, each controlling a different aspect or operation (e.g. via a slide gesture). When the value of one of the slides is adjusted, the corresponding values of the other slides change accordingly.
In some embodiments, the slide bars can be horizontally stacked or vertically spaced. The slide bars can be associated with a “Video Resolution” affordance 756, which when activated (e.g. via a slide gesture), enables the user to set a resolution size of the resulting video. The higher the resolution, the bigger the file, and the larger the bandwidth required to serve the files. Revenue can be received by charging users a fee relating to the desired resolution. With higher video resolution, higher rates can be charged for hosting and bandwidth costs.
Another slide bar can be associated with a “Max Slow Motion” affordance 758, which when activated (e.g. via a slide gesture), enables the user to set the maximum slow motion speed factor. As Video Resolution increases, the Maximum Slow Motion Effect (Max SlowMo) decreases and the Record Frames Per Second (Record FPS) decreases proportionally. Playback Frames Per Second (Playback FPS) is an independent variable and remains unchanged.
Another slide bar can be associated with a “Record Frames Per Second” affordance 760, which when activated (e.g. via a slide gesture), enables the user to set the recording FPS. The record FPS is the rate of which frames are captured by the camera. The higher the frame rate, the higher the slow motion effect with respect to a constant Playback FPS. As Record FPS increases, Max SlowMo increases and Video Resolution decreases proportionally.
As Record FPS decreases, Max SlowMo decreases and Video Resolution increases proportionally. As the user adjust the Record FPS 758 higher and lower, the values for the Max SlowMo and Video Resolution automatically adjust accordingly. Playback Frames Per Second (Playback FPS) is unchanged. The user can manually override and adjust the Video Resolution and Max SlowMo to lower the maximum selected by the software.
Still another slide can be associated with a “Playback Frames Per Second” affordance 762, which when activated (e.g. via a slide gesture), enables the user to set the playback FPS. The Playback FPS is the rate of which frames are played by the device. The higher the Playback FPS, the lower the slow motion effect with respect to a constant Record FPS.
The Playback FPS can be independent set without affecting either Recording Frames Per Second or Video Resolution.
As Playback FPS increases, Max SlowMo decreases proportionally.
As Playback FPS decreases, Max SlowMo increases proportionally.
As the user adjust the Playback FPS 762 higher and lower, the values for the Max SlowMo automatically adjust accordingly. Record FPS and Video Resolution are unchanged.
As Video Resolution decreases, the Max SlowMo increases and the Record FPS increases proportionally. Playback Frames Per Second (Playback FPS) is unchanged.
As the user adjust the Video Resolution 756 higher and lower, the values for the Max SlowMo and Record FPS automatically adjust accordingly. Playback FPS is unchanged.
User can select to create the original footage in high resolution but upload a lower resolution video to save on bandwidth and storage costs. The user has the option to save the high resolution original video to the local device, and/or upload to cloud for storage. Once uploaded, video files of high resolution can be resized into the proper format to optimize speed and size for the viewing device.
The maximum slow motion effect (Max Slow Motion 758) is a ratio of Record FPS to Playback FPS. The maximum slow motion effect uses existing frames only to create the slow motion effect when played in “real time” given the Playback FPS. It does not use frame adding or other digital enhancements or interpolated and extrapolated frames.
Max SlowMo is the maximum end of the range of usable slow motion effect that is available for the user. The user may choose to use a smaller slow motion range that is less than the Max SlowMo value.

Max SlowMo=Record FPS/Playback FPS

The user can set the Playback FPS 762 independently of all other variables. In this example, keeping the Playback FPS constant illustrates the function of the feature.
As the Max SlowMo increases, Record FPS increases and Video Resolution decreases proportionally.
As the Max SlowMo decreases, Record FPS decreases and Video Resolution increases proportionally.
As the user adjust the Max SlowMo 758 higher and lower, the values for the Record FPS and Video Resolution automatically adjust accordingly. Playback Frames Per Second (Playback FPS) is unchanged.
For example, recording fps=120, playback fps=30.
Maximum slow motion effect=4 times slower than normal speed.
The GUI 30 can further include an “Optimize” affordance 764, which when activated (e.g. via a slide gesture), enables the user to optimize the camera and/or playback settings to maximize the best video quality that the device can deliver. The user can select to optimize for video quality, file size, maximum slow motion effect, and combinations thereof.
The values in the Optimize 764 operations can be the settings for the maximum video quality and minimum size that the device supports. These are the “limits” for the range of values that are available for the user to select from.
To assist in understanding the utilization of the GUI 30 implementing at least in part some of the subroutines of the present technology, the following examples are provided, assume the following device supported recording frame rates:

    
    
        8K at 240 fps
        4 k at 480 fps
        2K at 960 fps
        1080 at 1920 fps
    
    


The UI automatically selects the values from the sets of values based on optimize routine selected. Optionally, the selected values are automatically highlighted and aligned vertically (left, middle, right) side of the screen.

FIG. 35 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays an alternative “Slow Motion Resolution” settings screen. In this example, the GUI 30 has all of the same features as the embodiment illustrated in FIG. 34. The difference is in the presentation of the controls to the end user. All functions are accessible through both embodiments.
In some embodiments, the UI automatically selects the values from the sets of values based on optimize routine selected. Optionally, the selected values are automatically highlighted and aligned in the same row at the top, middle or bottom of the screen.
In this example in FIG. 35, the GUI 30 can display and utilize multiple scrollable sections, with each being associated with “Video Resolutions”, “Max Slow Motion”, “Record FPS” and “Playback FPS” affordances. Each affordance can be activated by moving the scroll to the desired value (e.g. via an up-down slide gesture). The slide bars can be horizontally stacked or vertically spaced. The scrollable sections can highlight the selected value, respectively.
FIG. 36 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays a “Slow Motion Scale” screen. In some embodiments, the user can set custom settings for how the Slow Motion Scale control appears on the app and it's programmatic behavior in response to the user's input (e.g. via a left-right slide gesture).
In this example, a slide bar or number line 766 represents the slow motion factor levels available for the user. The range displayed is from “Normal” to “7×”. There can be a “>” symbol besides the last scale value, in this case“7×”, to represent that there are additional slow motion multipliers available but not displayed. The user can then scroll through the available slow motion multipliers and select how much or how little to limit the range of slow motion factor while recording.
The user can pinch at the number line and include more of the range of the slow motion to include in the live recording screen.
The user can set the orientation of the button to move right or left on the line 766 to control the speed. As exemplary illustrated, “Normal” is on the left and “Max” is on the right. The user would then slide his/her finger on the recording control from left to right to increase the slow motion factor.
A “Reverse” affordance 768 can be utilized and displayed on the GUI, which when activated (e.g. via a tap gesture), enables the user to reverse the display of the slide bare 766. If the user selects the “Reverse” option, then “Normal” would be on the right side, and “Max” is on the left. The user's motion is to slide from right to left on the line 766 to increase the slow motion factor.
FIG. 37 illustrates an exemplary embodiment “Screen Shot” of the device employing the GUI 30 of the present technology while the system displays an alternative Slow Motion Scale screen. In this example, the GUI 30 has all of the same features as the embodiment illustrated in FIG. 36. The difference is in the presentation of the slide bar or line 768 to the end user. In this example, the slide bar 768 is orientated in a vertical configuration along a left or right side of the GUI 30. All functions are accessible through both embodiments. The user can set custom settings for how the Slow Motion Scale control appears on the app and it's programmatic behavior in response to the user's input.
In some embodiments, there can be a “{circumflex over ( )}” symbol above the last scale value, in this case“11×”, to represent that there are additional slow motion multipliers available but not displayed. The user can then scroll through the available slow motion multipliers and select how much or how little to limit the range of slow motion factor while recording.
In any of the embodiments of the GUI, the user can return to a previous screen or proceed to the next screen by a sliding gesture across the screen in a left or right direction, or by a tap gesture on an icon or affordance indicating the direction of screen progression.
Alternatively, the GUI 30 can be configured or configurable to utilize additional user feedback associated with the device implementing the present technology. This feedback can use vibration frequency and intensity, and 3D tactile to indicate the zoom, speed factors, and/or other operational factors.
In use, it can now be understood that a user could initiate a camera operation using an electronic device that includes or is operably associated with the present technology software application, or the user could initiate camera operation using present technology software application that is operably associated with the camera.
Upon operation of the present technology software application, a user interface is provided to the user for controlling the functions of the present technology software application and/or the camera.
The user can initiate a recording function of the camera using the interface, at which time the present technology software application would receive any raw video data from the camera or remote video feed, which can be associated with a microphone or a peripheral microphone(s). During this operation, the raw video data from the camera and/or microphone is diverted to the present technology software application instead of a memory unit, which would normally receive the raw data from the camera.
The interface provides a simple input from the user to control the recording speed rate of the raw video data received from the camera. For exemplary purposes, this input by the user on the interface can be movement across a portion of a touchscreen or pressure applied to a portion of the touchscreen. It can be appreciated that this input can come in a variety of forms such as, but not limited to, movement of a cursor, voice commands, activation of icons, operation of switches or buttons, on-screen gestures, infrasonic devices, and the like.
If the user does not provide input to change the speed rate, then the raw video data from the camera is displayed and is written to memory.
Alternatively, if the user does provide input to change the speed rate, then the raw video data is processed using the present technology software application and its associated algorithms in real time. The raw video data includes one or more frames, and these frames processed to create in a final video data stream that corresponds to the speed rate inputted by the user.
This is accomplished utilizing the present technology software application to create a modified video data stream. This modified video data stream can be created by dropping specifically identified frames from the raw video data or adding frames to the raw video data by copying specially identified frames and adding these copied frames adjacent to their original frame or by “frame blending”, which interpolates one or more frames in between two reference frames. The number of dropped frames or added frames can be determined and repeated by the present technology software application until the desired speed rate is achieved.
The present technology software application can then write the raw video data or the modified video data stream to memory, thereby providing to be displayed a video in a normal speed rate, a fast motion speed rate or a slow motion speed rate.
It can be appreciated that the speed rate of the video is not modified after writing to memory, thereby recording the video in real time with or without special effects and omitting the need for postproduction editing to change the video speed rate.
The present technology can be configured or configurable so that the algorithm creates a smoother time modification of the video data stream. For example, the algorithm could fill in video gaps when the user jumps from one speed to another. The algorithm can interpolate data between two or more data points, thus creating even more smoothness, for example, when going from −3× slow to 4× fast.
During playback, the video can be very abrupt. This can be algorithmically corrected to smooth out the video to enhance the viewer's experience with perceived higher resolution during the transition into the beginning of each special effect, during each special effect and the transition from the special effect to normal time—occurring while the user is moving around and panning the camera as a user would need while capturing special moments (peak moments) in an active sporting event.
An example of “Peak moment” is when an object being videoed jumps, it is the instant where there is no more upward momentum, but the person has not yet begun to fall. Artificial intelligence (AI) can be utilized to calculate “peak moment” of the action in a scene being recorded, and take a predetermined desired action, such as using slow motion slightly before and slightly after the “peak moment”.
The present technology can be embedded to any camera device, such as action cameras like GoPro®, DSLR's, mirrorless cameras, Pro Level video gear, gimbals, tripods, on the camera and remotely triggered flash lighting, eye glass cameras, drones, webcams. The present technology can be embedded into remote controls and connected through Bluetooth® or other protocols, to existing electronic gear that does not have the present technology embedded.
The user interface of the present technology can be represented in 3-D or 2-D. The user can slide a finger or stylus side to side on the touchscreen of the electronic device in one plane of motion. With a 3-D user interface, the electronic device can sense the changes in depth of the user's controllers, the amount of pressure the user is applying, and adjust the special effects appropriately. Joysticks can be employed and utilized with the present technology.
The user interface could be pressure sensitive so that the user could press harder or softer on the device and the device would interpret these as controls to modify the playback speed with the fast forward and slow motion special effects.
The present technology can allow for recording at sufficiently high frames per seconds with the resulting “raw” unedited video (recorded with no special effects applied) can be edited post recording, and the slow motions will remain smooth because the high recording frame rate supports it relative to a slower playback fps.
It can be appreciated that brainwave sensing devices, implanted or surface attachment, or wireless remote sensing, can be utilized with the present technology to directly control the time speed special effects with a thought.
Compression technology can be utilized with the present technology to improve recording at even higher frame rate to record finer details in the scenery and reduce file size. Device performance can improve and users can therefore record at even higher frame rate to record finer details in the scenery while reducing the file size.
Audio processing algorithms can be utilized with the present technology to give the clearest and most understandable audios to the videos during segments where the scene speeds up and slows down. 3rd party API's from companies such as Dolby Labs, DTS, Inc., Fraunhofer Institut, Philips, Technicolor, IMAX, Sony, and others can be utilized to perform the audio processing.
Data encryption algorithms can be utilized with the present technology to provide secure transmission and storage of the videos.
Cryptography and blockchain technology algorithms can be utilized with the present technology to create a distributed ledger to record the original content creator of the videos produced with the present technology. The videos can be accessed by requiring cryptographic tokens to be “redeemed” for access permission.
It should be understood that the particular order in which the operations in the figures have been described is merely an example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods and/or processes described herein are also applicable in an analogous manner to the method described above with respect to the figures.
For situations in which the systems, interfaces and/or methods discussed above collect information about users, the users may be provided with an opportunity to opt in/out of programs or features that may collect personal information (e.g., information about a user's preferences or usage of a smart device, biometric data, and environmental data such as location). In addition, in some implementations, certain data may be anonymized in one or more ways before it is stored or used, so that personally identifiable information is removed. For example, a user's identity may be made anonymous so that the personally identifiable information cannot be determined for or associated with the user, and so that user preferences or user interactions are generalized (for example, generalized based on user demographics) rather than associated with a particular user. Data encryption can also be utilized and “tokenized” access using the blockchain technology can also be utilized to further obfuscate the user's identity.
Although some of various drawings illustrate a number of logical stages in a particular order, stages that are not order dependent may be reordered and other stages may be combined or broken out. While some reordering or other groupings are specifically mentioned, others will be obvious to those of ordinary skill in the art, so the ordering and groupings presented herein are not an exhaustive list of alternatives. Moreover, it should be recognized that the stages could be implemented in hardware, firmware, middleware, software, API's or any combination thereof.
While embodiments of the real time video special effects system and method have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the present technology. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the present technology, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present technology. For example, any suitable sturdy material may be used instead of the above described. And although creating special effects in video recordings while recording is in progress have been described, it should be appreciated that the real time video special effects system and method herein described is also suitable for change frame attributes, change record frame rate, change playback frame rate, and time compression and expansion and other real-time special effects associated with any data stream in real time.
Therefore, the foregoing is considered as illustrative only of the principles of the present technology. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the present technology to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the present technology.
