BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing apparatus, and more particularly to an editing apparatus suitable for applying to an editing apparatus capable of creating an edit list based on video and / or audio materials recorded on a plurality of types of recording media. Things.

[0004]

2. Description of the Related Art Conventionally, when a video / audio signal is edited, first, an image and a voice based on the video / audio signal are displayed on a display and output from a speaker, and an operator confirms the voice and places a desired portion in a plurality of places. After that, an editing list is created which defines the editing order in which order and how to connect these specified video and audio.

If the clips overlap in time when the editing list is created, the overlapping portion of each clip is subjected to crossfading processing, and at this time, the overlapping portion of the clip that precedes in time is faded out and the time is reduced. A process for fading in a subsequent overlapping portion of a clip (hereinafter, this process is referred to as a crossfading process) has been performed.

Next, an editing process is performed on the basis of the edit list, and a desired editing sound is obtained by performing a mixing process on the editing sound among the editing video and the editing sound thus obtained.

[0007]

At the time of creating such an edit list, a frame corresponding to a clip is formed on the audio track displayed on the screen, and at a desired time on the time axis within the frame of the clip. There has been proposed an editing list creating method that can freely adjust the audio level. According to this editing list creation method, a desired audio level is set at the time point desired by the operator even in the overlapping portion between the clip frames to be subjected to the crossfading process.

However, in the conventional crossfade processing, the frames of clips overlapping in time are simply faded out and faded in. Therefore, the audio level set by using the above-described editing list creation method is reflected in the crossfade processing period. There is a problem that will not be.

In order to solve such a problem, a method of manually adjusting the audio level at a desired point in time in the frame of the clip to be subjected to the crossfading process according to the operation of the operator is conceivable. However, in this method, since the adjustment of the sound level at a desired point in the cross-fade processing period is performed while fading out or in, the operator needs to repeatedly adjust the sound level at the desired point in time to approach the desired level. As a result, there is a problem that the editing work becomes complicated.

Further, there is a possibility that it may be difficult for the operator to sufficiently distinguish whether or not the fade-out and the fade-in are actually performed in the overlapping portion of the clip frame to be cross-fade processed.

The present invention has been made in view of the above points, and an object of the present invention is to propose an editing apparatus capable of significantly improving the efficiency of editing work.

[0012]

According to the present invention, there is provided an editing system for editing data which defines editing contents for obtaining an editing audio in which first and second audio materials are connected in accordance with an external operation. When the level of each audio material is set by external operation in the editing device that creates
An edit data creating means for creating edit data reflecting the setting also at the time of crossfading is provided.

As a result, even when the first and second audio materials overlap each other on the time axis when the edited data is created,
The first and second audio materials can be faded out or faded in while maintaining the level set at each desired point in the overlapping portion. Thus, when the level adjustment in the overlapping portion is manually performed by the operator, The complicated editing work can be avoided.

nd) Displayed as a display section 80C and a lead display section 80D.

By directly inputting numerical values using the dialog of the fader point window 80, it is possible to make detailed settings which are difficult to make on the main screen 30.

Here, when the editing list is created, one of the first or second (third or fourth) audio tracks 35 is created.
The frame of the clip in G or 35H (35I or 35J) and the frame of the clip in the other second or first (fourth or third) audio track 35H or 35G (35J or 35I) are the time scale 35A. If there is an overlap with the above time code, a process for lowering the audio level of the preceding clip and raising the audio level of the succeeding clip for the overlapping time code (hereinafter referred to as cross-fade processing) is executed. It has been made to be.

The first to fourth audio tracks 35G-
When the execution or cancellation of the crossfading process is set for 35J, a title portion represented by a setting (Setting) of a plurality of title bars 70 provided in the upper part of the main screen 30 (hereinafter, referred to as a setting title) ) When 70D is selected by mouse operation,
As shown in FIG. 16, a pull-down menu 82 is superimposed and displayed below the setting title 70D.

When an option (Option) mode 82A of the pull-down menu 82 is selected by operating the mouse, a dialog for the option mode 82A opens to open a window at a predetermined position on the main screen 30 (hereinafter referred to as an option window). Call) 83 is superimposed.

In this option window 83, FIG.
Auto crossfade (Auto C
ross Fade) button 83A is displayed, and it is possible to select whether or not to execute the above-described cross-fade processing by clicking with a mouse operation.

That is, the auto cross fade button 83
When A is turned on, there is a case where the time code overlaps between the clip frames between the first and second audio tracks 35G and 35H or between the third and fourth audio tracks 35I and 35J. , The crossfade processing is automatically executed for the respective overlapping portions.

As a result, as shown in FIG. 18, the audio track to be subjected to the crossfade processing on the edit list creating section 35 has the upper end to the lower end of the audio track according to the time change from the start time to the end time of the crossfade processing. (Or from the lower end to the upper end) with a straight line (hereinafter referred to as a cross-fade line)
CFL1 or CFL2 is displayed (FIG. 1
9). This cross fade line CFL1 or CFL2
Represents the rate of fade-out or fade-in in accordance with the passage of the cross-fade processing time.

On the other hand, when the auto cross fade button 83A is turned off, between the first and second audio tracks 35G and 35H and between the third and fourth audio tracks 35I and 35J. The crossfade processing is not executed regardless of whether or not there is a portion where the time code overlaps between the clip frames. As a result, as shown in FIG. 20, the above-described crossfade lines CFL1 and CFL2 displayed on the audio track to be crossfaded on the edit list creating section 35 are deleted.

In a clip where a cross fade has already been set, the auto cross fade button 83 is set.
The crossfading process is not canceled only by turning A off. In this case, as shown in the order of FIGS. 21A to 21D, after the clip frame is moved to eliminate the cross-fade portion (cross-fade lines CFL1 and CFL2), automatic adjustment of the cross-fade is performed. Do
Further, when the overlap of the time codes between the clip frames is eliminated and the time codes overlap as before, the cross-fading lines CFL1 and CFL1 and CFL1 are similar to the other new clip frames.
FL2 does not occur.

Here, in practice, when the frames of each clip displayed on the edit list creating section 35 have overlapping portions in the time code on the time scale 35A, the CPU 20 sets the overlapping portions to each other. Rather than simply executing the crossfade processing, the crossfade processing is executed while retaining the audio level of the rubber band set for each clip in the overlapping portion.

In this case, the CPU 20 inserts the above-mentioned cross-fade line C into the frame of the audio track to be cross-fade processed on the edit list creating section 35.
In a state where FL1 or CFL2 is displayed, the fade-out or fade-in rate of the cross-fade line located at the same time code as the fader point is set to the sound level of each fader point set on the rubber band. The multiplication is performed, and the result of the multiplication is written to the RAM 22 as crossfade data.

At this time, the fade-out or fade-in ratio of the cross-fade line displayed in the clip frame of the audio track is simply the ratio of the height to the track width without performing decibel conversion. As a result, if the position of the predetermined time code on the cross fade line is in the middle of the track width, the ratio of the fade out or fade in of the cross fade line is 50.
[%], And the audio level of the fader point corresponding to the time code is multiplied by 0.5.

If a fader point is not set in the fader track, the original sound, which is the default value, is the fade-out or fade-in ratio of the cross-fade line displayed in the clip frame of the audio track to be cross-fade processed. Crossfade data is generated by multiplying the audio level.

Thus, for example, FIG.
As shown in FIG. 3 (A) and FIG. 24 (A), in a state where the cross fade line CFL1 is displayed in the clip frame of the first audio track 35G, the corresponding first
The audio level of the fader point on the rubber band in the fader track 73A in FIG. 22 (B) and FIG. 23 (B) respectively depends on the ratio of the crossed-out line CFL1 to be faded out in the cross-fade processing target portion.
24, and gradually decreases as shown in FIG.

Here, assuming that the ratio of the cross-out line in the audio track to be cross-fade processed is f [%], the cross-fade data val is given by the following equation.

[0125]

(Equation 1)

Is represented by However, if the operator sets data by operating the mouse on the main screen 30,
In this state, even at the fader point set at the lowermost end of the rubber band, since the internal data is -18 [dB], that is, the internal data is 127, a slight sound may be output. Therefore, the audio level of the fader point positioned at the lowermost end of the rubber band on the main screen is set to -60 [dB], that is, 0 for the internal data.

When the operator operates the option window 83,
Is opened and the decibel [dB] is selected from the unit buttons 83B, the cross-fade data val can be converted to decibel [dB]. At this time, if the decibel value is decibel, formula

[0128]

(Equation 2)

Is represented by On the other hand, when the percentage [%] is selected from the unit buttons 83B, the crossfade data val can be converted into the percentage [%]. At this time, if the value of the crossfade data val is P, the following equation is obtained.

[0130]

(Equation 3)

Is represented by

In fact, the result of performing the above-described crossfading processing on the first and second fader tracks 73A and 73B shown in FIG. 18 is shown in FIG. 25, respectively.
It is shown in a chart as shown in (A) and (B). According to this chart, the time code changes from "01: 00.05: 00" to "0
1: 00.09: 00 ”during the crossfade processing period
It can be seen that the fader track 73A fades out and the second fader track 73B fades in.

(4) Cross-Fade Data Generation Setting Procedure Here, the CPU 20 actually executes the edit list creation section 35 in accordance with the cross-fade data generation procedure RT1 shown in FIG.
The frame of each clip displayed on the time scale 35
In the case where the time code has an overlapping portion on A, the above-described cross-fade data is generated by executing the cross-fade processing while maintaining the audio level of the rubber band set for each clip in the overlapping portion.

That is, when the CPU 20 sequentially sets a clip frame at a desired position on the time scale 35A in the first to fourth audio tracks 35G to 35J in the edit list creating unit 35 on the main screen 30, the CPU 20 executes a cross-over process. The fade data generation procedure RT1 is started in step SP0, and in the following step SP1, the first and second steps are performed.
If there is a portion where the time code overlaps between the clip frames between the audio tracks 35G and 35H, or between the third and fourth audio tracks 35I and 35J, the time scale of the overlapping portion is displayed on the time scale 35A. The time information of the start time and the end time is sequentially stored in the RAM 22.
In the database.

Next, the CPU 20 proceeds to step SP2, and executes the first to fourth audio tracks 35G to 35J.
At the lower ends of the first to fourth feeder tracks 73A, respectively.
When a fader point is set at a desired position on the rubber band in the corresponding fader track in a state where .about.73D is selectively displayed, time information indicating the time point on the time scale 35A for the corresponding fader point is displayed. , And data representing the sound level at that time are sequentially stored in R
It is stored in the database of AM22.

Thereafter, the CPU 20 proceeds to step SP3, determines whether or not the auto cross fade button 83A has been selected while the option window 83 is displayed on the main screen 30, and if a negative result is obtained. Returning to step SP1, the above processing is repeated.

On the other hand, if an affirmative result is obtained in step SP3, the CPU 20 sets and displays a cross-fade line in each of the frames of the clip whose time code overlaps between the audio tracks, and sets the time at the start of the cross-fade processing. Information and the time information of each fader point during the crossfade processing period
The data is read from the database of M22 and rearranged (sorted) in time order along the time scale 35A. As a result, the time list of the crossfade data within the crossfade processing period is determined.

Subsequently, in step SP5, the CPU 2
0 selects the first time (the earlier of the start time of the crossfading process or the time of the earliest fader point) in the time list of the crossfade data and initializes the database in the RAM 22. Thereafter, the process proceeds to step SP6.

In this step SP6, the CPU 20
Creates cross-fade data for each fader point within the cross-fade processing period. At this time, the cross fade data is stored not only in the time list, but also in the audio level (-60 to +6 [dB]) of each fader point, the fade out or fade in of the cross fade line located at the same time code as the corresponding fader point. Cross-fading data (unit is [dB]) by multiplying each by the ratio (0 to 100 [%])
Is also created.

Thereafter, the CPU 20 proceeds to step SP7, determines whether or not the above-described arithmetic processing of step SP6 has been executed for all the fader points in the crossfading processing period. If a negative result is obtained, the CPU 20 proceeds to step SP7. Proceeding to SP8, the arithmetic processing is executed for the fader point provided at the next time point. On the other hand, if a positive result is obtained in step SP7, the CP
U20 stores the created cross-fade data in the database in the RAM 22, and then proceeds to step SP1 as it is.
The process proceeds to 0, and the crossfade data generation procedure RT1 ends.

(5) Operation and Effect of Embodiment In the above configuration, in the editing apparatus 1, the operator operates the track map window 72 by operating the mouse while the main screen 30 is displayed on the display 12 when the editing list is created. When a fader track corresponding to a desired audio track is selected from the track map window 72, a rubber band is set for each clip below the audio track displayed in the edit list creating section 35. The resulting fader track is displayed on the time scale 35A.

In this state, the operator sets a fader point sequentially to a desired time code on a rubber band in a desired fader track, thereby setting a fader for a desired clip in an audio track corresponding to the relevant fader track. can do.

When the editing list is created, if the clip frame in one audio track and the clip frame in the other audio track have an overlapping part in the time code on the time scale 35A, the operator operates the mouse by operating the mouse. When the auto crossfade button 83A is selected from the displayed option window 83, a crossfade line is displayed during the crossfade processing period which is the overlapping portion of the clip frame in the audio track.

At this time, the sound level of each fader point within the cross fade processing period in the fader track is sequentially multiplied by the fade-out or fade-in rate of the cross fade line located at the same time code as the corresponding fader point. Crossfade data (edit data) can be created for audio levels between the frames of the clip to be crossfaded.

Thus, when the frames of the clips displayed on the edit list creating section 35 have overlapping portions in the time code on the time scale 35A, the audio level of the rubber band set for each clip in the overlapping portion is changed. Cross-fade processing by fade-out or fade-in can be performed without any loss.

According to the above configuration, when an edit list is created, a fader track for setting a fader is displayed on the main screen 30 in correspondence with the audio track, and each clip frame displayed on the edit list creating section 35 is displayed. In the case where each has an overlapping portion in the time code on the time scale 35A, the audio level of the rubber band set for each clip in the overlapping portion is also reflected at the time of the crossfading process. It is possible to prevent the audio level set for the clip from being impaired, and thus to realize an editing apparatus that can significantly improve the efficiency of editing work.
