The video editing system is also constituted by the video editing device 10 including the video selecting section 13 for selecting the video material from the digital VTR for reproduction 1 and the video camera 2, the audio selecting section 14 for selecting the audio material from the digital VTR for reproduction 1 and the video camera 2, the HDD 12 as a non-linearly accessible recording medium for storing the video material selected by the video selecting section 13 and the audio material selected by the audio selecting section 14, the input operating section 18 including the keyboard and the mouse, the editing control section 11 for controlling the video editing device 10 in accordance with the operation information from the input operating section 18, the display section 17 for displaying editing material information, the special effect unit 16 for carrying out special effect processing on the video material, and the audio mixer 15 for processing the audio material. The video editing system is further constituted by the digital VTR for recording 5 as another external equipment.
For editing the video material and the audio material by using the above-described editing device, the following two methods are considered.
A first method is to determine in advance materials necessary for a program by the video editing device 10 and then actually shoot video materials and audio materials based on the determined information. After the end of shooting, the materials are recorded on the video editing device 10 while it is confirmed whether the materials determined in advance before shooting have been actually shot. The materials are edited so as to produce a material for broadcasting by the VTR for recording 5.
A second method is to store all the first shot materials into the video editing device 10, then select and edit materials necessary for a program, and output the edited materials to the VTR for recording 5.
The first method is to shoot predetermined materials and then carry out editing by the editing device 10, while the second method is to randomly collect materials and select necessary materials therefrom. In the present embodiment, the second method is employed as an editing method of video materials and audio materials by the editing device 10. Also, in the present invention, recording of materials to the editing device 10 from the VTR for reproduction 1 and editing of materials are carried out on a GUI (graphic user interface) displayed on the display section 17 of the video editing device 10. Therefore, each screen displayed on the display section 17 of the editing device 10 will be first described, and the operating method of each screen will be described subsequently.
FIG. 2 shows each screen displayed on the display section 17 of the video editing device 10 and the relation between the respective screens. As shown in FIG. 2, there are six types of screens, that is, an initial screen 21, a program selection screen 22, a program configuration screen 23, an editing screen 24, a material screen 25 and a utility screen 26. The initial screen 21 enables transition to three types of screens, that is, the program selection screen 22, the material screen 25 and the utility screen 26. Also, transition from these three types of screens to the initial screen 21 is possible. In addition, transition between the program selection screen 22, the program configuration screen 23 and the editing screen 24 is possible. The above-described six types of screens are stored in an advance in a ROM, not shown, of the editing control section 11 and are displayed on the display section 17. Operation of each screen and transition between the respective screens may be carried out by operating the input operating section 18. Such operation will be described later in detail.
Each of the initial screen 21, the program selection screen 22, the program configuration screen 23, the editing screen 24, the material screen 25 and the utility screen 26 will now be described.
The initial screen 21 is displayed on the display section 17 when the power of the video editing device 10 is turned on or when the video editing device 10 is reset. As a matter of course, the initial screen may be displayed through transition from the other screens. The operator may shift from this initial screen 21 to the other screens by actually operating the input operating section 18.
On the initial screen 21, as shown in FIG. 3, three title bars are displayed, that is, a title bar 31 displaying “PROGRAM SELECTION/CONFIGURATION/EDITING”, a title bar 32 displaying “MATERIAL”, and a title bar 33 displaying “UTILITY”.
By operating the input operating section 18, for example, clicking the mouse constituting the input operating section 18 to select one of the three title bars, the operator may shift to the corresponding screen. Specifically, if the title bar 31 displaying “PROGRAM SELECTION/CONFIGURATION/EDITING” is selected, the screen shifts to the program selection screen 22. If the title bar 32 displaying “MATERIAL” is selected, the screen shifts to the material screen 25. If the title bar 33 displaying “UTILITY” is selected, the screen shifts to the utility screen 26.
The program selection screen 22 will now be described. The program selection screen 22 may be opened from the initial screen 21 or the program configuration screen 23 and the editing screen 24.

The material having the material ID “T001-00” of the second row is a material for carrying out DSK as the background of the material having the material ID “V005-03” of the first row, and is discriminated by the initial letters “T” and “S” of the material ID. The above-described series of operation is carried out at a time point before the coverage for actually shooting the material, and the cameraman shoots the material based on the material ID registered on the program configuration screen 23. Specifically, immediately before shooting the material of the registered material ID, the cameraman inputs the material ID to a shooting equipment such as a VTR-loaded camera, by operating an operating button or GUI of this camera so as to record the material ID on the memory cassette of the material tape cassette 101. By this shooting method, the material and the material ID are recorded on the material tape cassette in the corresponding manner.
FIG. 8 shows the state that recording of each material classified by the material ID and the material name onto the HDD 12 of the video editing device 10 is being carried out in the program configuration screen 23.
In the material name display screen 63 of FIG. 8, in the monitor columns 47 of the materials of the material ID “V005-03” in the first row, the material ID “T001-00” in the second row, the material ID “V000-00” in the third row, and the material ID “V001-00” in the fourth row, images of the materials are displayed by overlook display. It is thus indicated that these materials are already recorded on the HDD 12. Since the material having the material ID “T001-00” in the second row is a still picture, a single image thereof is provided instead of overlook display.
The items of material time and recording time in the material name display screen 63 are items to be inputted when a video material is recorded. Therefore, the recording time and the recording date of the materials corresponding to their respective material IDs and material names are displayed in the first to fourth rows in the material name display screen 63, as shown in FIG. 8. Since the material having the material ID “T001-00” in the second row of the material name display screen 63 is a still picture, the item of the material time is left blank with no display.
For recording a material, a row indicating a desired material registered in the material name display screen 63 is selected by operating the input operating section 18, and the “REC” button 44 of the operation menu 35 is selected by operating the input operating section 18. Thus, recording of the material is started.
In the example of FIG. 8, a material corresponding to the material ID “V002-00” and the material name “COVERAGE CUT 1” in the fifth row of the material name display screen 63 is selected and recorded. The “REC” button 44 is also highlighted in display with respect to the selected material, thus indicating that the corresponding row is selected. The material of the fifth row is being recorded, and its image is displayed by overlook display in the monitor column 47 so as to display the status of recording. Therefore, the status of recording of the video material may be known in real time. In the present embodiment, the overlook display of the image is provided by extracting an image every predetermined period from a series of images of the corresponding material and displaying the extracted images in an overlapping manner.
When recording of the material corresponding to the material ID in the fifth row of the material name display screen 63 is completed, all the images displayed by overlook display of the corresponding material appear in the monitor column 47 in the material name display screen 63 so that completion of recording of the video material and confirmation of the contents of the video material may be carried out. Before the material corresponding to the material ID is recorded on the HDD 12 of the video editing device 10, only frames referred to as index pictures are displayed as in the seventh and eighth rows of the material name display screen 63 shown in FIG. 8. However, during recording onto the HDD 12 by the above-described method or at the time of completion of recording, the images displayed by overlook display are shown in the monitor column 47 of the material name display screen 63.
Specifically, after the input to the material name display screen 63 of the program configuration screen 23 shown in FIG. 7 is completed, actual shooting of the material is carried out. When the material tape cassette 101 completed in shooting is inserted and reproduced in the digital VTR for reproduction 1, frames before and after the interval between materials and frames before and after a scene change (referred to as index pictures as described above) are displayed in the monitor column 47 of the program configuration screen 23, as in the seventh and eighth rows of FIG. 8, so that these frames are automatically displayed in a list. That is, only the index pictures corresponding to the material ID are first displayed in the monitor column 47 of the program configuration screen 23. This is because the shooting equipment has a function to record the above-described index pictures so that the index pictures are first reproduced by the digital VTR for reproduction 1. When recording onto the HDD 12 of the video editing device 10 is completed by the above-described operation, the images displayed by overlook display are displayed in the monitor column 47 of the program configuration screen 23.
As described above, only the material corresponding to the material ID displayed on the material name display screen 63 of the program configuration screen 23 may be automatically recorded onto the recording medium of the video editing device 10 by operating the “REC” button 44 of the operation menu 35. The recording medium used in the present embodiment is the HDD (hard disc drive) 12 as shown in FIG. 1. The reason the material corresponding to the material ID on the program configuration table may be thus recorded on the recording medium of the video editing device 10 is that the material and its material ID are associated with each other by recording the material ID in the cassette memory (memory in cassette or MIC) before actually shooting the material.
Specifically, the material ID is recorded in the MIC of the material cassette tape 101 immediately before shooting the material, and then, the actual material corresponding to the material ID is recorded on the tape of the material cassette tape 101 by a camera-loaded VTR or the like. Then, the material tape cassette 101 is inserted in the digital VTR for reproduction 1, and the information operated by the input operating section 18 is outputted to the memory read section 1b of the digital VTR for reproduction 1 through the editing control section 11. The material ID corresponding to the operated information is read out from the MIC by the memory read section 1b. Since information about the position on the tape where the actual material corresponding to the material ID is recorded is provided within the MIC, the actual material is searched and recorded onto the HDD 12.
Thus, only the material corresponding to the material ID may be recorded onto the HDD 12 by operating the input operating section 18 on the above-described program configuration screen 23 displayed on the display section 17. Recording of each material displayed on the program configuration screen 23 with respect to each program registered on the above-described program selection screen 22 may also be automatically carried out on the basis of the registered material ID displayed on the material name display screen 63.
Referring to FIG. 8, if a material is shot with a material ID appended thereto though there is no material corresponding to the material ID, a material selection screen 230 as shown in FIG. 9 is displayed on another window on the program configuration screen 23 at an arbitrary time point, for example, at a time point before recording the material corresponding to the each material ID onto the HDD 12 of the video editing device 10 using the program configuration screen 23. In this material selection screen 230, an index picture 232 is displayed with a material ID 231 appended thereto. The material ID 231 and the index picture 232 corresponding to the material ID 231 represent a material displayed on the material selection screen 230 with its material ID not being appended on the material name display screen 63 of the program configuration screen 23. When the material ID 231 on the material selection screen 230 is newly registered to the material ID on the material name display screen 63, the material automatically recorded onto the HDD 12 of the video editing device 10. The time point when the material selection screen 230 is displayed as another window on the program configuration screen 23 may be an arbitrary time point, for example, a time point when recording of a material ID registered on the program name display screen 63 onto the HDD 12 is completed (as shown in FIG. 11).
The material registered on the program configuration screen 23 is not entirely recorded at a time. The material which cannot be recorded is not recorded from the digital VTR for reproduction 1 onto the HDD 12 and is recorded onto the digital VTR for recording 5 through the HDD 12. This is because the HDD 12 has a limited recording capacity. For example, with respect to a material having a material time exceeding 15 minutes, which is displayed in the material time column 46 of the material name display screen 63, the material portion corresponding to the time up to 15 minutes is recorded on the HDD 12 and the remaining material portion exceeding 15 minutes is directly recorded on the digital VTR for recording 5 and displayed on the display section 17 through the editing control section 11 from the digital VTR for recording 5.
FIG. 10 shows the state that the material is monitored on the program configuration screen 23.
In the state shown in FIG. 10, recording of the materials is completed except for a material corresponding to a material ID “V004-00” and a material name “COVERAGE CUT 2” in the seventh row of the material name display screen 63. The incompletion of recording of the material corresponding to the material ID “V004-00” may be known from the blank material time column in the seventh row of the material name display screen 63 and the monitor column 47 where only the index picture (IP) is displayed.
For monitoring the recorded video material, the corresponding row in the material name display screen 63 is selected by operating the input operating section 18 in accordance with the material ID and the material name of the desired material, and the “MONI” button 51 of the operation menu 35 is selected by operating the input operating section 18, for example, clicking the mouse. In FIG. 10, the material ID “V002-00” and the material name “COVERAGE CUT 2” in the fifth row of the material name display screen 63, and the “MONI” button 51 of the operation menu 35 are highlighted in display. Thus, it is indicated that the material in this row and the “MONI” button are selected.
For monitoring the selected video material, images of the corresponding material displayed by overlook display in the monitor column 47 are displayed entirely with the lapse of time. In FIG. 10, a video material 52 corresponding to the material ID “V002-00” in the fifth row (the highlighted row) of the material name display screen 63 is entirely displayed in a sequential manner. Since the image sequentially shifts in accordance with the progress of recording to the video editing device 10, the position of the monitored video may be known in real time. The status of video monitoring is indicated by the position of a scroll button 43a of the monitor scroll bar 43.
FIG. 11 shows the state that recording of each material displayed on the program configuration screen 23 to the video editing device 10 is completed.
The completion of recording of all the materials may be known from the overlook display of the images corresponding to each material in the monitor column 42 in the material name display screen 63 and the display of the material time of each video material in the “MATERIAL TIME” column in the material name display screen 63. Since the material corresponding to the material ID “T001-00” and the material name “NO.72” in the second row is a still picture, the “MATERIAL TIME” column is blank.
The editing screen 24 will now be described.
The editing screen 24 is adapted for carrying out editing of a video material recorded to the video editing device 10 through the above-described program configuration screen 23 and an audio material corresponding to the video material, for example, setting of special effects of the video material, setting of DSK, trimming, and recording and mixing of the audio material.
The editing screen 24 may be opened from the program configuration screen 23 by selecting the “Q-SHEET” button of the operation menu 35 in the program configuration screen 23 by operating the input operating section 18, for example, clicking the mouse.
The editing screen 24 includes a program display section 42, a source name display screen 64, an operation menu 35, and a scroll bar 36, as shown in FIG. 12.
The program display section 42 has the same constitution as the program display section 42 in the program configuration screen 23, and the same contents as those of the program display section 42 of the program configuration screen 23 are displayed in this section. That is, the program display section 42 is displayed on the uppermost part of the editing screen 24 and includes a program ID 24a and a program name 24b. 
The source name display screen 64 includes 11 items of “SOURCE”, “VIDEO A” 53, “VIDEO B” 54, “VIDEO EFFECT”, “DSK (digital still keying)” 55, “VIDEO A” (further divided into first and second rows), “VIDEO B” (further divided into first and second rows), “AUDIO EFFECT”, “ANNOUNCE”, “SOUND EFFECT 1”, and “SOUND EFFECT 2” sequentially from top to bottom in the leftmost column. These 11 items will be later described in detail.
The operation menu 35 is displayed on the lowermost part of the editing screen 24, and includes 11 buttons of “DSK NEW”, “AUDIO NEW”, “DELETE”, “ALTER”, “SAVE”, “REC”, “MONI”, “STOP”, “AUTOMATIC EFFECT PROCESSING”, “PROGRAM REPRODUCTION”, and “END” sequentially from left to right. These 11 buttons will be later described in detail.
The scroll bar 36 is displayed on the lower side of the source display screen 64. The scroll button 36a can be caused to scroll the source name display screen 64 in left and right directions by operating the input operating section 18.
The example shown in FIG. 12 is the editing screen 24 related to the program having the program ID “0003” and the program name “IN-HOUSE NEWS NO.72”.
In the “VIDEO A” row 53 and the “VIDEO B” row 54 of the source name display screen 64, the video material corresponding to each material is displayed by overlook display. Specifically, in the “VIDEO A” row 53, the video material displayed by overlook display corresponding to the material ID “V005-03” and the material name “OPENING TITLE” is displayed, and the material ID and the material name of this video material are displayed on the upper part of the video material. In addition, the video materials corresponding to the material IDs “V001-00” and “V003-00”, and the material IDs and the material names corresponding to these video materials are displayed similarly. In the “VIDEO B” row 54, too, the material ID, the material name and the video material are displayed by overlook display similar to that in the “VIDEO A” row 53. Using the videos displayed in the “VIDEO A” row 53 and the “VIDEO B” row 54, video special effects are made as later described.
In FIG. 12, the material corresponding to the material ID “T001-00” and the material name “NO.72” is displayed in the “DSK” row 55. In this “DSK” row 55, an image (still picture) for keying is displayed. Actual keying from this “DSK” row 55 will be described later.
In addition, on the source name display screen 64 of FIG. 12, “VIDEO A” 591, “VIDEO B” 592, “AUDIO EFFECT” 59, “ANNOUNCE” 593, “SOUND EFFECT 1” 594, and “SOUND EFFECT 2” 595 for audio processing are displayed.
In the VIDEO A row 591 and the VIDEO B row 592, audio materials corresponding to “VIDEO A” 53 and “VIDEO B” 54 are displayed, respectively. Level display of the audio material is made, or the audio material ID or audio material name is displayed. That is, in FIG. 12, the audio material is displayed in the VIDEO A row 591, corresponding to the video material name “OPENING TITLE” in the VIDEO A row 53, and the audio material is displayed in the VIDEO B row 592, corresponding to the video material name “HEADLINE” in the VIDEO B row 54. In the present embodiment, since there are two output channels of the audio material, the display of each of the VIDEO A row 591 and the VIDEO B row 592 is divided in two rows.
The AUDIO EFFECT row 59 displays an icon for setting a special effect of the audio material so that the audio effect is actually made. The audio effect will be described later.
In the ANNOUNCE row 593, the audio material recorded together with the video material at the time of shooting is not displayed, and an audio material which is generated with respect to the recorded video material by an announcer viewing the video material is displayed, if any. The display is made by level display or band display, which indicates post-recording.
The SOUND EFFECT 1 row 594 and the SOUND EFFECT 2 row 595 display any sound effects reproduced by the sound effect reproducing section 4 of FIG. 1. The display thereof is similar to that of ANNOUNCE 593.
The editing screen 24 shown in FIG. 12 is in a state before carrying out various effect processing.
The program display section 42, the source name display screen 64, the operation menu 35 and the scroll bar 36 in the editing screen 24 are thus described.
A method of setting a video special effect and a method of setting an audio effect using the editing screen 24 will now be described. First, the video special effect setting method will be described.
FIG. 13 shows the state that setting of the video special effect is being carried out on the editing screen 24.
The setting of the video special effect is carried out in the VIDEO EFFECT row 56 of the source name display screen 64 in the editing screen 24. That is, when the special effect is not carried out, each icon displayed in the VIDEO EFFECT row 56 is blank like an icon 56d. 
All the blank icons are shifted to the position where the special effect is intended to be carried out. Specifically, when dissolve processing is intended to be carried out so that the image of the material name “OPENING” gradually fades away while the next image of the material name “HEADLINE” gradually appears, a blank icon is shifted to the position of the first frame in the VIDEO B row 54 where the material name “HEADLINE” is displayed. That is, icons displayed in the VIDEO EFFECT row 56 is displayed in a time series from left to right, corresponding to the VIDEO A row 53 and the VIDEO B row 54.
Next, when the blank icon is shifted to the desired position, what type of special effect is to be made is determined. Specifically, as the blank icon is selected by operating the input operating section 18, for example, clicking the mouse, a video effect selection window 57 is displayed. The video effect selection window 57 shows icons indicating types of special effects, as shown in FIG. 13, and a rightmost scroll bar 57d and a lowermost scroll bar 57e in the window 57 can be caused to scroll the video effect selection window 57 by operating the input operating section 18, for example, clicking the mouse.
In this embodiment, the above-described dissolve processing effect is intended to be made at the position of an icon 56a in VIDEO EFFECT 56, between the material name “OPENING” and the material name “HEADLINE”. Therefore, a dissolve processing icon 57a in the video effect selection window 57 is selected by operating the input operating section 18, for example, clicking the mouse, so that the blank icon in the VIDEO EFFECT row 56 turns into the icon 57a like the icon 56a of FIG. 13. That is, the special effect is set to carry out dissolve processing between the material name “OPENING” in VIDEO A and the material name “HEADLINE” in VIDEO B, at the position of the icon 56a in the VIDEO EFFECT row 56 of FIG. 13. By similar operation, at the position of an icon 56b and an icon 56c as displayed in the VIDEO EFFECT row 56 of FIG. 13, special effect displayed in the icons are made.
The icon 56d is left blank in FIG. 13. This indicates the state that what type of special effect is to be made is not determined and that no icon in the video effect selection window 57 is selected. Therefore, no special effect is made at this position.
In the video effect selection window 57, icons for making various effects are displayed other than the icon 57a for making the dissolve effect. In the case of FIG. 13, an icon 57b for performing multi-effector processing, an icon 57c for performing slide processing of an image, and an icon 57e for performing wipe processing of an image are displayed. As a matter of course, other icons for performing various special effect processing are displayed.
Subsequently, time setting of the video material for the special effect is carried out. FIG. 14 shows the state that the effect time is being set.
The blank icon displayed in the VIDEO EFFECT row 56 in the source name display screen 64 becomes an icon indicating a special effect of the video effect selection window 57, and then, the input operating section 18 is operated, for example, “15” is inputted by the keyboard, so as to display the number of frames 15 on the lower part of the icon 56d in the VIDEO EFFECT row 56 of FIG. 14. This number of frames indicates the number of frames on which a video effect is to be made. With the icon 56d shown in FIG. 14, the dissolve processing between the video material names “STUDIO RECORDING 2” in VIDEO A 53 and “COVERAGE CUT 1” in VIDEO B 54 is carried out at the position indicated in FIG. 14 on the previous 15 frames (in this case, the material name “COVERAGE CUT 1”) so that the image is dissolved to the image of the material name “STUDIO RECORDING 2”. In the case where the effect time is not set, the effect time is determined by predetermined time setting.
An editing point input method will now be described, in which an editing point of the video material on which a video special effect should be made is inputted so as to make the video special effect.
FIG. 15 shows the editing screen 24 in the state that an editing point is being inputted.
The input of an editing point is carried out by operating a part of the input operating section 18 which is referred to as a jog/shuttle dial shown in FIG. 16, or a display on the editing screen 24 or on a screen different from the editing screen 24. In the following description, a part of the input operating section 18 is operated. The details of this operation will be described later.
First, when an image displayed by overlook display in the VIDEO A row 53 or the VIDEO B row 54 of the source name display screen 64 on the editing screen 24 shown in FIG. 15 is selected by operating the input operating section 18, for example, clicking the mouse, the jog/shuttle dial 7 shown in FIG. 16 becomes effective. The jog/shuttle dial 7 shown in FIG. 16 includes an in-button 7a, an out-button 7b, and a dial 7c. The dial 7b is a so-called jog dial and shuttle dial.
By operating this dial 7c of the jog/shuttle dial 7, the position of an image on which a special effect is to be made is adjusted. For example, with respect to the material name “COVERAGE CUT 1” 54b in VIDEO B 54 on the editing screen 24 of FIG. 15, the position of the video material 54d which is currently selected and displayed entirely may be operated by the dial 7c of the jog/shuttle dial 7. Specifically, the position where a special effect is to be made with respect to the video material indicated by the material name “COVERAGE CUT 1” may be adjusted by rotating the dial 7c to the left or to the right. That is, an in-point of the video material on which the special effect is to be made (the first frame on which the special effect is to be made) is determined by rotating the dial 7c to move the image indicated by the video material name “COVERAGE CUT 1” in VIDEO B 54 and pressing the in-button 7a of the jog/shuttle dial 7 at an appropriate position. Similarly, an out-point (the last frame on which the special effect is to be made) is determined by pressing the out-button 7b of the jog/shuttle dial 7.
The method of inputting the video editing point for the special effect by operating the jog/shuttle dial 7 is described above. In the above-described example, the jog/shuttle dial 7 is a part of the input operating section 18. It may also be considered that a window displaying the jog/shuttle dial 7 is displayed on the editing screen 24 or on another screen. In such case, the in-button 7a, the out-button 7b and the dial 7c are selected or rotated by operating the input operating section 18, for example, clicking the mouse, so that the input of the editing point may be realized similarly to the above-described example.
The special effect setting method for the video material by utilizing the editing screen 24 is described above.
A method of setting an audio effect on an audio material will now be described.
An audio effect on an audio material is made in the AUDIO EFFECT row 59. Similar to the operation in VIDEO EFFECT 56 on the video material, a blank icon is selected and moved to a position where an audio effect is to be made, by operating the input operating section 18, for example, clicking the mouse. As the blank icon at this position is selected by operating the input operating section 18, for example, clicking the mouse, an audio effect window 58 shown in FIG. 17 is displayed as another window on the editing screen 24. In this audio effect window 58, as a desired audio effect icon is selected, the selected audio effect icon is displayed in the blank icon as displayed in the AUDIO EFFECT row 59 of FIG. 18. The audio effect window 58 shown in FIG. 17 displays audio effect icons 58a, 58b, 58c and 58d for cross-fading. The vertical axis of each audio effect icon corresponds to the audio level, and the horizontal axis corresponds to the time. The display of a function corresponds to an audio material at an out/in-point.
When the selected audio effect icon is displayed in AUDIO EFFECT 59, the effect time is set similarly to the operation for the video special effect. For setting the effect time, the input operating section 18 is operated, for example, the numeral “10” is inputted by the keyboard, similarly to the setting of the effect time of the video special effect, so that an audio effect indicated by the audio effect icon is made on the audio material of the video material of preceding and succeeding five frames. When the effect time is not operated by the operation of the input operating section 18, the audio effect is made on the audio material corresponding to a predetermined number of frames.
The above-described video special effect setting method and audio effect setting method are carried out as follows. That is, the video material recorded on the video editing device 10 is stored in the video special effect unit 16 from the HDD 12 under the command from the editing control section 11 by the above-described series of operations on the editing screen 24 displayed on the display section 17. The actual special effect such as dissolve processing is made by the video special effect unit 16, and the processed video material is recorded again on the HDD 12. Also, the audio material recorded on the video editing device 10 is stored in the audio mixer 15 from the HDD 12 under the command from the editing control section 11 by the above-described series of operations on the editing screen 24 displayed on the display section 17. The actual audio effect is made by the audio mixer 15, and the processed audio material is recorded again on the HDD 12.
Keying processing of the video material as shown in FIG. 18 will now be described.
Keying processing is processing for changing the color of a background or a line of a still picture or a frame. A method of setting a video keying effect will now be described.
First, in the source name display screen 64 on the editing screen 24, a DSK material 55a displayed in the DSK (digital still keying) row 55 is selected by operating the input operating section 18, for example, clicking the mouse. When the DSK material 55 is selected, a DSK effect setting window 60 is displayed on the editing screen 24. In this DSK effect setting window 60, the setting necessary for keying processing is carried out. The DSK effect setting window 60 includes a pattern setting section 60a, an execution time setting section 60b, a mat color setting section 60c, and a border color setting section 60d, as shown in FIG. 18.
The pattern setting section 60a is adapted for setting a keying effect pattern. Each pattern is displayed as an icon, with the vertical axis representing the keying level and the horizontal axis representing the time. A desired pattern is selected by operating the input operating section 18, for example, clicking the mouse. As the execution time setting section 60b, an execution time for carrying out keying processing is displayed below the icon displaying each pattern, and is set by operating the input operating section 18, for example, inputting a numeral by the keyboard.
The mat color setting section 60c is adapted for setting the color of a predetermined region of a video region, mainly, the background of the image. Specifically, when a set color alter button 600c of the mat color setting section 60c is selected by operating the input operating section 18, a color setting window, not shown, is displayed on the DSK effect setting window 60. This color setting window displays icons of various colors, and when a desired color is selected by operating the input operating section 18, the selected color is displayed in the set color section of the mat color setting section 60c. 
The border color setting section 60d is adapted for setting the color of a region, mainly, the line of the image. Specifically, similar to the operation of the mat color setting section 60b, a “SET COLOR ALTER” button of the border color setting section 60d is operated and a desired color is selected from a color setting window. Also, the width of the border is set in this section. In the example shown in FIG. 17, the width of the border is four dots.
Trimming at a position for carrying out keying processing is carried out by the jog/shuttle dial 7, which is used for inputting the editing point in the above-described video special effect. Specifically, in the case where keying processing is to be carried out on the material of the material name “OPENING”, a desired frame in VIDEO A 53 on the editing screen 24 is selected by the dial 7c, and the in-button 7a of the jog/shuttle dial 7 is operated.
If the configuration of the program is altered, the trimming state of the material is returned to the initial state.
The case where additional setting of key processing is carried out on the editing screen 24 will now be described with reference to FIG. 19.
In the source name display screen 64 on the editing screen 24, as the “DSK NEW” button 351 of the operation menu 35 is selected by operating the input operating section 18, a DSK material window 61 shown in FIG. 19 is displayed. In the DSK material window 61, an image (still picture) different from the material displayed on the DSK row 55 is displayed as an icon. When one of the icons is selected by operating the input operating section 18, the icon is newly displayed in the DSK row 55 so that the above-described operation of keying processing may be carried out on the selected new icon, that is, the new material.
The DSK material window 61 displays the above-described image as an icon. In FIG. 19, DSK materials such as a material ID “T001-00” and an icon display 61a of an image (still picture) indicated by the material ID, and a material ID “T002-00” and an icon display 61b of an image (still picture) indicated by the material ID are displayed in a list. A scroll bar 61d is displayed on the lowermost part of the DSK material window, and a button 6 le can be caused to scroll the DSK material window 61 on this window screen by operating the input operating section.
In the DSK material window 61 thus constituted, an image (still picture) as a new target of keying processing may be inserted in the DSK row 55 as follows. That is, when the “DSK NEW” button 351 of the operation menu 35 is selected on the editing screen 24 by operating the input operating section 18, the DSK material window 61 is displayed. A desired icon is selected from the icons displayed in the DSK material window 61 on the editing screen 24 by operating the input operating section 18, and a position where keying processing is intended to be executed is selected in the DSK row 55 in the source name display screen 64 on the editing screen 24 by operating the input operating section 18.
