Abstract

This invention realizes an editing system and control method thereof capable of significantly improving working efficiency of editing work. A proxy editing terminal device creates an EDL with low-resolution video/audio data, resulting in reducing time to create the EDL. Further, the low-resolution video/audio data and high-resolution video/audio data having the same contents and different resolutions are previously stored, so that the creation of a final edit list with the high-resolution video/audio data based on the EDL can be started in a short time after the EDL is created with the low-resolution video/audio data. Thus working efficiency of the editing work can be significantly reduced with reducing time to create the EDL and the final edit list.

Claims

1. An editing system comprising:

first storage and retaining means for storing and retaining high-resolution video data of edit material;

second storage and retaining means for storing and retaining low-resolution video data of said edit material;

first edit list creation means for creating a first edit list specifying edit details of rough editing by using said low-resolution video data;

second edit list creation means for creating a second edit list specifying edit details of actual editing by using said high-resolution video data; and

a network for connecting said first edit list creation means and said second edit list creation means, wherein

said second edit list creation means reads said first edit list from said first edit list creation means via said network and creates said second edit list based on the first edit list.

2. The editing system according to claim 1, wherein

said second edit list creation means makes said first storage and retaining means automatically read high-resolution video data corresponding to said low-resolution video data when reading said first edit list.

3. The editing system according to claim 1, wherein

said second edit list creation means makes said first storage and retaining means preferentially read high resolution video data around edited points of said edit material out of said high-resolution video data.

4. The editing system according to claim 2, wherein

said high-resolution video data automatically read from said first storage and retaining means is written in third storage and retaining means.

5. The editing system according to claim 3, wherein

said high-resolution video data preferentially read from said first storage and retaining means is written in third storage and retaining means.

6. The editing system according to claim 2, wherein

said second edit list creation means makes said first storage and retaining means preferentially read high-resolution video data around edited points of said edit material out of said high-resolution video data.

7. The editing system according to claim 6, wherein

said high-resolution video data preferentially read from said first storage and retaining means is written in third storage and retaining means.

8. A control method of an editing system, comprising:

a first step of storing high-resolution video data of edit material in first storage and retaining means;

a second step of storing low-resolution video data of said edit material in second storage and retaining means;

a third step of creating a first edit list specifying edit details of rough editing by using said low-resolution video data in first edit list creation means; and

a fourth step of reading said first edit list from said first edit list creation means via a network, and creating a second edit list specifying edit details of actual editing by using said high-resolution video data based on the first edit list in second edit list creation means.

9. The control method according to claim 8, wherein

said fourth step makes said first storage and retaining means automatically read high-resolution video data corresponding to said low-resolution video data when reading said first edit list.

10. The control method according to claim 8, wherein

said fourth step makes said first storage and retaining means preferentially read high-resolution video data around edited points of said edit material out of said high-resolution video data.

11. The control method according to claim 9, wherein

said high resolution video data automatically read from said first storage and retaining means is written in third storage and retaining means.

12. The control method according to claim 10, wherein

said high-resolution video data preferentially read from said first storage and retaining means is written in third storage and retaining means.

13. The control method according to claim 9, wherein

said fourth step makes said first storage and retaining means preferentially read high-resolution video data around edited points of said edit material out of said high resolution video data.

14. The control method according to claim 13, wherein

said high-resolution video data preferentially read from said first storage and retaining means is written in third storage and retaining means.
