A to 14D are recorded on a video tape.

In the case of the editing apparatus 1 in addition to the above configuration,
At the time of the preview mode or the recording mode, the CPU 20 performs the preview process or the recording process as shown in FIG. 8 based on the edit list created or in the process of being created by using the edit list creating unit 35 of the main screen 30. Editing range T ₀
Until clip appears to be reproduced by the same video tape recorder 14A~14D within (period T _1),
By controlling each of the video tape recorders 14A to 14D and the hard disk device 2 sequentially and continuously, the video signal and / or the audio signal of the necessary clip are sequentially and continuously reproduced.

Further, the CPU 20 reproduces the necessary clipped video signal and / or audio signal in this manner in succession, and again within the remaining editing range (period T ₂ ) by the same video tape recorders 14A to 14D. Each video tape recorder 14A-1 until the clip to be reproduced appears.
By sequentially and continuously controlling the 4D and hard disk device 2, the video signal and / or the audio signal of the necessary clip are sequentially and continuously reproduced, and thereafter, the same processing is sequentially repeated.

As described above, in the editing apparatus 1, at the time of the preview mode or the recording mode, each video tape recorder 1A until the clip reproduced by the same video tape recorder 14A to 14D appears based on the edit list.
4A to 14D and the processing for controlling the hard disk device 2 in a continuous manner are repeated sequentially as necessary. Thus, the same video tape recorders 14A to 14D are used.
The reproduction process until the clip reproduced by D appears can be performed in real time.

(4) Continuous Control Processing Procedure Here, in the preview mode and the recording mode, the CPU 20 controls the video tape recorders 14A to 14D and the hard disk device 2 according to the continuous control processing procedure RT1 shown in FIG. Control.

0D, confirms the location of the front end of the time code value is smallest clip video signal and or audio signal in the time line 35A of 61A to 61D (video tape or hard disk device 2), the editing range at next step SP4 T ₀ It is determined whether or not the storage locations of all the clips included in the folder have been confirmed.

If a positive result is obtained in step SP4, the CPU 20 proceeds to step SP9. If a negative result is obtained, the CPU 20 proceeds to step SP5, and the storage location of the video signal and / or audio signal of the clip is determined by any video tape recorder. It is determined whether it is a video tape loaded in 14A to 14D.

Then, the CPU 20 executes this step SP5
If a negative result is obtained in step SP3, the process returns to step SP3. Until a positive result is obtained in step SP4 or step SP5, the time code at the front end of the frames 60A to 60D and 61A to 61D corresponding to the clip to be confirmed in step SP3 is changed. The loop of steps SP3-SP4-SP5-SP3 is repeated while changing the order from the smallest one.

Then, the CPU 20 eventually proceeds to step SP
If an affirmative result is obtained in step 5, the program proceeds to step SP6, in which the video tape recorder 1 loaded with the video tape on which the video signal and / or audio signal of the clip is recorded.
The numbers 4A to 14D are stored, and thereafter, the process proceeds to step SP7 to determine whether or not the numbers have appeared before.

Obtaining a negative result in step SP7 means that there is no clip reproduced by the same video tape recorders 14A to 14D as the clip reproduced at a time earlier than the clip at the time of preview or recording. Means that the CPU 20
Returns to step SP3, and thereafter repeats steps SP3 to SP7 in the same manner as described above.

On the other hand, obtaining an affirmative result in step SP7 means that the same video tape recorders 14A to 14D as the clips are reproduced in the clips which are reproduced earlier during the preview or during the recording. It means that there is a clip, then C
The PU 20 proceeds to step SP8 and determines a continuous editing range (periods T ₁ and T ₂ in FIG. 8) assuming that continuous reproduction processing is performed from the first clip to that clip.

Thereafter, the CPU 20 proceeds to step SP
In step 9, the corresponding video tape recorders 14A to 14D and the hard disk device 2 are controlled via the system control unit 4 so that the video signal and / or audio signal of the corresponding clip can be found.

Further, the CPU 20 thereafter controls the corresponding video tape recorders 14A to 14D, the video input unit 5, the video output unit 6, the digital video / audio input / output unit 7, the video special input / output unit via the system control unit 4 as described above. By controlling the effect processing unit 8, the audio input / output / mixer unit 9 and / or the disk control unit 10 at a predetermined timing as necessary, the continuous editing range determined in step SP8 is
In the preview mode, the edited video based on the editing list is displayed on the monitor 16 and the edited audio is output from the speaker. In the recording mode, the edited video and audio are recorded on the video tape via the corresponding video tape recorders 14A to 14D. Let it.

[0092] The CPU20 may eventually this Purebiyu processing or recording processing is completed, whether having conducted the Purebiyu processing or recording processing for all the clips in the edit range T ₀ detected at step SP2 proceeds to step SP10 to decide.

If the CPU 20 obtains a negative result in step SP10, it proceeds to step SP11, and the respective video tape recorders 14 stored in step SP6.
After resetting the numbers of A to 14D, the process returns to step SP2, and the confirmation of the storage location of the video signal and / or audio signal of each clip is restarted from the last clip subjected to the continuous editing processing in step SP9. The processing is performed while sequentially repeating step SP11 in the same manner as described above.

Further, the CPU 20 will eventually execute step SP.
If a positive result is obtained in step 10, the process proceeds to step SP12 to end the continuous processing procedure RT1.
