     DETAILED DESCRIPTION 
     Enjoying music videos has long been a source of entertainment for music fans. The availability of low-cost WebCams, microphones, mobile phones with video-recording capabilities, and broadband connections now allows video enthusiasts to create and share their own videos. This technology also allows people to combine multiple videos, for example to combine videos of individual musicians performing the same song. For example, a user might combine four such videos into a single video with four panes, with each pane containing one of the videos. In such videos, users can collaborate on vocal ensembles or piece together instrumental components of a song. 
     While this content format shows promise, current tools for creating such videos are difficult to use. First the user must create multiple videos, or coordinate the recording of multiple videos with collaborators. Each video must be timed well with the previously recorded video to ensure all videos are keeping the same time. Then the user must stitch those videos together using a desktop video editing tool, adjust the volume and audio of the clips, align them so the timing across the videos makes sense, and format the layout of the component videos to be visually compelling. Finally, the user must export the resulting creation to a format that is suitable for sharing, share the video on the user&#39;s preferred network, and draw attention to it. These difficulties inherently limit the number of creators of such content because the process requires access to, and knowledge of, complex video editing software. Furthermore, the time investment can be considerable, with some well-known creators reporting hundreds of hours of video-editing time. 
     Various embodiments of the disclosed technology address these difficulties, providing a simple and fun tool for creating collaborative videos in only minutes. The disclosed collaboration tool can be used quickly and without any special knowledge on any computer, smart phone, or similar electronic device. For clarity and concision of description, embodiments for making and using music videos are described. However, it should be understood that the disclosed technology applies to any type of video, for example including comedy, visual arrangements, beauty, dance, and any other type of video that can benefit from synchronization of multiple videos from different contributors. 
     In the disclosed embodiments, a library hosted by a remote server stores collections of music video clips, where all of the music video clips in one collection have the same duration, and are associated with a particular piece of music. As used herein, the term “video” is used to denote a combination of images and sound, for example such as images and sound of a musician performing. A user may use the tool, which may be implemented on an electronic device, such as a smart phone, to select one or more of the music video clips. In response, the collaboration tool downloads the selected music video clips, and loops and displays the downloaded music video clip(s) according to the minimum duration across all clips. In the case of multiple downloaded music video clips, the collaboration tool loops and displays the clips in unison, such that they are synchronized. For example, for a particular song, the user may use the tool to download and display one clip of a drummer playing the chorus of a song, and another clip of a singer singing the chorus. In this example, because the two clips are displayed synchronized, the drummer and singer appear to be playing together on the collaboration tool user interface. 
     The app may operate in a mixing mode, where the user can use the user interface to swap out the clips for other clips. Continuing the above example, the user can replace the drummer with a bass player, also playing the chorus of the song. When the user is happy with the clips that are looping, the user can then publish the combination of the clips as a collaboration. For example, the user can cause the app to upload the collaboration to the collaboration library. Other users of the collaboration tool can find and enjoy the collaboration in the collaboration library. The user can also advertise the collaboration in other ways, for example by exporting or linking to the collaboration and sharing it to the user&#39;s social network. The collaboration tool has numerous other features, which are described in detail below. 
     In some embodiments, a user may export the collaboration in a format suitable for sharing the collaboration to other platforms. For example, the user may export the collaboration in a rendered format, where the clips are joined together. 
     The app may operate in a recording mode, where the user can record a music video clip to go with the looping clips. As those clips continuously loop, the app may record the user singing and/or playing a musical instrument, for example with the smart phone&#39;s front-facing or rear-facing camera, and may display the recording along with the looping clips. The user can record for as many repetitions of the looping clips as desired. 
     When the user stops recording, the collaboration tool may automatically segment the recording into takes, each having the same duration as the looping clips, and being synchronized with them. The user can then create a collaboration by selecting one of the takes, which the tool may associate with the downloaded clips. The user can then publish the collaboration. For example, the user can cause the app to upload the selected take to the collaboration library, where it is associated with the downloaded clips, which of course are still stored in the collaboration library. Other users of the collaboration tool can find, play back, and enjoy the collaboration in the collaboration library, and can download the selected take to use in their own collaborations. The user can also advertise the collaboration, for example as described above. The collaboration tool has numerous other features, which are described in detail below.

Playing a collaboration may include looping (that is, repeatedly and continuously playing) one or more music video clips associated with a particular piece of music. When the collaboration includes multiple music video clips, all of the music video clips may be associated with the same piece of music, may be of the same duration and tempo, and may be played in unison, that is, synchronously. For example, all of the music video clips in the collaboration may be 15 seconds in duration and may all have a tempo of 120 beats per minute. And all of the music video clips in the collaboration may start and stop at the same places in the piece of music. With some or all these features, the music video clips of the collaboration combine to form a pleasing musical ensemble that repeats as long as the user likes. In some embodiments, the tool may create pools of songs based on underlying characteristics like tempo and key, to allow users to combine different songs to make creative mashups that sound good together. The tool may allow users to search within the app for clips according to these underlying characteristics. 
       FIG. 4  is an example screenshot  400  that may be produced by the collaboration tool in the feed mode according to some embodiments of the disclosed technology. In the example of  FIG. 4 , a collaboration  402  is shown that includes three music video clips looping together: a person playing a synthesizer, at  404 ; a person singing, at  406 ; and a person playing a keyboard, at  408 . In the described embodiments, the collaborations have three video clips, all having the same aspect ratio. In other embodiments, a collaboration may have a different number of video clips, video clips of differing aspect ratios, or both. Several icons are shown in the screenshot  400 , at  410 , which allow the user to share or flag the collaboration  402 , for example to share the collaboration to an Instagram™ story, a Facebook™ page, and the like. 
     Returning to  FIG. 3 , the collaboration tool detects and responds to user input. For example, in response to detecting a vertical swipe on a touch screen of a smart phone, at  304 , the collaboration tool selects another collaboration, at  306 . In some embodiments, each time a new collaboration is selected, the tool starts to play the music video clips in the selected collaboration in unison, starting at time 0. The tool may also display gestures the user can make for controlling the tool.  FIG. 5  is an example screenshot  500  that may be produced by the collaboration tool in the feed mode in response to a swipe up according to some embodiments of the disclosed technology. In response to the swipe up, the collaboration tool scrolls the display up to replace the current collaboration  402  with a new collaboration  502 . The new collaboration  502  may be associated with the same piece of music, or with a different piece of music. In some embodiments, during the scrolling, the collaboration tool causes the sound of the old collaboration to fade out while the sound of the new collaboration fades in, creating a smooth blending effect. 
     Returning to  FIG. 3 , in response to detecting a tap on one of the music video clips in a collaboration, at  308 , the collaboration tool shows metadata for that clip, at  310 . The metadata may include, for example, the name of the piece of music associated with the collaboration, the username of the contributor of the clip, and the like. In response to detecting a horizontal swipe on one of the music video clips in a collaboration, at  312 , the collaboration tool enters the remixing mode, at  314 . 
       FIG. 6  depicts a process  600  for a remixing mode  212  of a music video collaboration tool according to some embodiments of the disclosed technology. The process  600  may be performed by one or more elements of the example system  100  of  FIG. 1 . Referring to  FIG. 6 , the process  600  may include replacing the music video clip horizontally swiped, at  312  in  FIG. 3 , with another music video clip associated with the same piece of music, at  602 , thereby creating a new collaboration for the same piece of music. In some embodiments, the collaboration tool causes the sound of the old clip to fade out while the sound of the new clip fades in, creating a smooth blending effect. The tool then plays the collaboration, for example in the manner described above with reference to  FIG. 2 . The user may then horizontally swipe any of the music video clips in the looping collaboration. 
       FIG. 7  is an example screenshot  700  that may be produced by the tool in the remixing mode according to some embodiments of the disclosed technology. In the example of  FIG. 7 , a collaboration  702  is shown that includes three music video clips looping together: a person singing, at  704 ; a person playing guitar, at  706 ; and a person playing drums, at  708 . Also shown in the screenshot  700 , are a “+” button  710  and a “Publish” button  712 . 
     The tool monitors user input. Returning to  FIG. 6 , responsive to detecting a horizontal swipe, at  606 , the collaboration tool replaces the swiped music video clip with another music video clip associated with the same piece of music, at  602 , and then begins looping the new collaboration, at  604 . In some embodiments, the collaboration tool causes the sound of the old clip to fade out while the sound of the new clip fades in, creating a smooth blending effect. The tool may start the collaboration at time 0, or may continue the looping from the time of the swipe. This process may be repeated as many times as the user likes. 
     The user may place the collaboration tool in the recording mode at any time. Responsive to detecting a tap on a “+” button  710 , at  608 , the collaboration tool may enter the recording mode, at  610 . In some embodiments, the tool may enter the recording mode when a user swipes left on a music video clip, and select a new music video clip when a user swipes right.

The process  800  may be performed by one or more elements of the example system  100  of  FIG. 1 . Referring to  FIG. 8 , the process  800  may include detecting a tap on one of the music video clips in the collaboration, at  802 . Responsive to detecting such a tap, the collaboration tool shows video of the user in place of the tapped music video clip, at  804 . The video of the user may be captured, for example, by a front-facing camera of a smart phone executing the collaboration tool. 
       FIG. 9  is an example screenshot  900  that may be produced by the collaboration tool on entering the recording mode  214  according to some embodiments of the disclosed technology. Referring to  FIG. 9 , the collaboration tool may number each of the music video clips, and may prompt the user to select which one to replace with the user&#39;s recording. In the drawings of these screenshots, cross-hatching is used to indicate parts of the screen that are dimmed. 
       FIG. 10  is an example screenshot  1000  that may be produced by the collaboration tool after the user has tapped one of the music video clips according to some embodiments of the disclosed technology. In the example of  FIG. 10 , the user has tapped the clip numbered  2 , and the collaboration tool has replaced that clip with live video of the user. The music video clips may continue to loop during this process. To prevent feedback, the tool may prompt the user to wear headphones, at  1002 . The user may proceed by tapping a “Next” button  1004 . 
     In some embodiments, the tool allows the user to adjust the playback volume of each of the music video clips by vertically swiping each video clip.

The user may proceed by tapping a “Next” button  1106 . 
     In some embodiments, the collaboration tool automatically compensates for latencies introduced by a headset when recording. The latencies may be obtained from headset manufacturing specifications or other sources, may be determined empirically, or the like. In particular, during recording, the playback of images may be started later than the playback of sound, by an amount substantially equal to the input latency of the headset, so that the image and sound playbacks appear synchronized to the user. Similarly, the recorded sound may be shifted forward in time so as to be synchronized with the recorded images, and with the playback sound and images. In particular, the capture of images of the user may be started later than capture of sound of the user, by an amount substantially equal to the output latency of the headset. In this manner, the latencies introduced by the headset may be accommodated. 
       FIG. 12  is an example screenshot  1200  that may be produced by the collaboration tool at the next step according to some embodiments of the disclosed technology.

       FIG. 17  depicts a block diagram of an example computer system  1700  in which various of the embodiments described herein may be implemented. The computer system  1700  may be implemented in any device. For example, the computer system  1700  may be implemented in a smartphone, tablet, laptop, automotive head unit, and the like. In some embodiments, parts of the computer system  1700  may be implemented in the cloud. 
     The computer system  1700  includes a bus  1702  or other communication mechanism for communicating information, and one or more hardware processors  1704  coupled with bus  1702  for processing information. Hardware processor(s)  1704  may be, for example, one or more general purpose microprocessors. 
     The computer system  1700  also includes a main memory  1706 , such as a random access memory (RAM), cache and/or other dynamic storage devices, coupled to bus  1702  for storing information and instructions to be executed by processor  1704 . Main memory  1706  also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by processor  1704 . Such instructions, when stored in storage media accessible to processor  1704 , render computer system  1700  into a special-purpose machine that is customized to perform the operations specified in the instructions. In particular, the instructions may implement the disclosed embodiments. 
     The computer system  1700  further includes a read only memory (ROM)  1708  or other static storage device coupled to bus  1702  for storing static information and instructions for processor  1704 . A storage device  1710 , such as a magnetic disk, optical disk, or USB thumb drive (Flash drive), etc., is provided and coupled to bus  1702  for storing information and instructions. 
     The computer system  1700  may be coupled via bus  1702  to a display  1712 , such as a liquid crystal display (LCD) (or touch screen), for displaying information to a computer user. An input device  1714 , including alphanumeric and other keys, is coupled to bus  1702  for communicating information and command selections to processor  1704 . Another type of user input device is cursor control  1716 , such as a mouse, a trackball, or cursor direction keys for communicating direction information and command selections to processor  1704  and for controlling cursor movement on display  1712 . In some embodiments, the same direction information and command selections as cursor control may be implemented via receiving touches on a touch screen without a cursor. 
     The computing system  1700  may include a user interface module to implement a GUI that may be stored in a mass storage device as executable software codes that are executed by the computing device(s). This and other modules may include, by way of example, components, such as software components, object-oriented software components, class components and task components, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. 
     In general, the word “component,” “engine,” “system,” “database,” data store,” and the like, as used herein, can refer to logic embodied in hardware or firmware, or to a collection of software instructions, possibly having entry and exit points, written in a programming language, such as, for example, Java, C or C++. A software component may be compiled and linked into an executable program, installed in a dynamic link library, or may be written in an interpreted programming language such as, for example, BASIC, Perl, or Python. It will be appreciated that software components may be callable from other components or from themselves, and/or may be invoked in response to detected events or interrupts. Software components configured for execution on computing devices may be provided on a computer readable medium, such as a compact disc, digital video disc, flash drive, magnetic disc, or any other tangible medium, or as a digital download (and may be originally stored in a compressed or installable format that requires installation, decompression, or decryption prior to execution). Such software code may be stored, partially or fully, on a memory device of the executing computing device, for execution by the computing device. Software instructions may be embedded in firmware, such as an EPROM. It will be further appreciated that hardware components may be comprised of connected logic units, such as gates and flip-flops, and/or may be comprised of programmable units, such as programmable gate arrays or processors. 
     The computer system  1700  may implement the techniques described herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computer system causes or programs computer system  1700  to be a special-purpose machine. According to one embodiment, the techniques herein are performed by computer system  1700  in response to processor(s)  1704  executing one or more sequences of one or more instructions contained in main memory  1706 . Such instructions may be read into main memory  1706  from another storage medium, such as storage device  1710 . Execution of the sequences of instructions contained in main memory  1706  causes processor(s)  1704  to perform the process steps described herein. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions. 
     The term “non-transitory media,” and similar terms, as used herein refers to any media that store data and/or instructions that cause a machine to operate in a specific fashion. Such non-transitory media may comprise non-volatile media and/or volatile media. Non-volatile media includes, for example, optical or magnetic disks, such as storage device  1710 . Volatile media includes dynamic memory, such as main memory  1706 . Common forms of non-transitory media include, for example, a floppy disk, a flexible disk, hard disk, solid state drive, magnetic tape, or any other magnetic data storage medium, a CD-ROM, any other optical data storage medium, any physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, NVRAM, any other memory chip or cartridge, and networked versions of the same. 
     Non-transitory media is distinct from but may be used in conjunction with transmission media. Transmission media participates in transferring information between non-transitory media. For example, transmission media includes coaxial cables, copper wire, and fiber optics, including the wires that comprise bus  1702 . Transmission media can also take the form of acoustic or light waves, such as those generated during radio-wave and infra-red data communications. 
     The computer system  1700  also includes a communication interface  1718  coupled to bus  1702 . Network interface  1718  provides a two-way data communication mechanism coupling to one or more network links that are connected to one or more local networks. For example, communication interface  1718  may be an integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, network interface  1718  may be a local area network (LAN) card to provide a data communication connection to a compatible LAN (or WAN component to communicated with a WAN). Wireless links may also be implemented. In any such implementation, network interface  1718  sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information. 
     A network link typically provides data communication through one or more networks to other data devices. For example, a network link may provide a connection through local network to a host computer or to data equipment operated by an Internet Service Provider (ISP). The ISP in turn provides data communication services through the world wide packet data communication network now commonly referred to as the “Internet.” Local network and Internet both use electrical, electromagnetic, or optical signals that carry digital data streams. The signals through the various networks and the signals on network link and through communication interface  1718 , which carry the digital data to and from computer system  1700 , are example forms of transmission media. 
     The computer system  1700  can send messages and receive data, including program code, through the network(s), network link and communication interface  1718 . In the Internet example, a server might transmit a requested code for an application program through the Internet, the ISP, the local network and the communication interface  1718 . 
     The received code may be executed by processor  1704  as it is received and/or stored in storage device  1710 , or other non-volatile storage for later execution. 
     Each of the processes, methods, and algorithms described in the preceding sections may be embodied in, and fully or partially automated by, code components executed by one or more computer systems or computer processors comprising computer hardware. The one or more computer systems or computer processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). The processes and algorithms may be implemented partially or wholly in application-specific circuitry. The various features and processes described above may be used independently of one another, or may be combined in various ways. Different combinations and sub-combinations are intended to fall within the scope of this disclosure, and certain methods or process blocks may be omitted in some implementations. The methods and processes described herein are also not limited to any particular sequence, and the blocks or states relating thereto can be performed in other sequences that are appropriate, or may be performed in parallel, or in some other manner. Blocks or states may be added to or removed from the disclosed example embodiments. The performance of certain of the operations or processes may be distributed among computer systems or computers processors, not only residing within a single machine, but deployed across a number of machines. 
     As used herein, a circuit might be implemented utilizing any form of hardware, software, or a combination thereof. For example, one or more processors, controllers, ASICs, PLAs, PALs, CPLDs, FPGAs, logical components, software routines or other mechanisms might be implemented to make up a circuit.
