Abstract

Digital video (DV) formatted image streams may be converted into an intermediate format having a lower resolution than the original image streams. A user may then edit the intermediate formatted image streams to generate a sequence of edit commands. The edit commands may then be processed to generate an output image stream based on the original image streams. The output image stream may be in any desired format, including DV format. The sequence of edit commands may also be processed to generate a preview image stream in the intermediate format.

Claims

1. A method comprising:

receiving a compressed frame of video data;

generating from said compressed frame of video data a command; and

video editing said compressed frame of video data based on the command.

2. The method of claim 1, including capturing uncompressed video data.

3. The method of claim 2, including:

processing said uncompressed video data to generate said compressed frame of video data wherein said compressed frame of video data to be of a relatively less data density than that of said uncompressed video data.

4. The method of claim 3, including generating an edit command to transform said uncompressed video data into said compressed frame of video data.

5. The method of claim 4, including editing said compressed frame of video data based on the edit command.

6. The method of claims 4, including decompressing said compressed frame of video data to generate an image stream.

7. The method of claim 2, further including lowering the resolution of said uncompressed video data to enable a frame-based editing thereof.

8. The method of claim 7 including incorporating a sequence of edit commands into said compressed frame of video data to cause said frame-based editing of said uncompressed video data.

9. An apparatus comprising:

an interface to receive an uncompressed digital video signal;

a device operably coupled to said interface to transform the uncompressed digital video signal into a compressed frame of video data; and

an editor operably coupled to said device to receive said compressed frame of video data to generate a command therefrom to cause video editing of said compressed frame of video data.

10. The apparatus of claim 9, said interface to capture said uncompressed digital video signal to derive a stream of frame-based video data.

11. The apparatus of claim 9, said editor to process said compressed frame of video data, wherein said compressed frame of video data to be of a relatively less data density than that of said uncompressed digital video signal.

12. The apparatus of claim 11, said device to generate an edit command to transform said compressed frame of video data.

13. The apparatus of claim 12, said editor to perform editing of said compressed frame of video data based on the edit command.

14. The apparatus of claim 13, said editor to decompress said compressed frame of video data to generate an image stream.

15. The apparatus of claim 10, said device to lower the resolution of said uncompressed video data to enable a frame-based editing thereof.

16. The apparatus of claim 15, said editor to incorporate a sequence of edit commands into said compressed frame of video data to cause said frame-based editing of said compressed frame of video data.

17. An article comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising:

receiving a compressed frame of video data;

generating from said compressed frame of video data a command; and

video editing said compressed frame of video data based on the command.

18. The article of claim 17, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising capturing uncompressed video data.

19. The article of claim 18, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising:

processing said uncompressed video data to generate said compressed frame of video data, said compressed frame of video data to be of a relatively less data density than that of said uncompressed video data.

20. The article of claim 17, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising generating an edit command to transform said compressed frame of video data.

21. The article of claim 17, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising editing said compressed frame of video data based on the edit command.

22. The article of claim 17, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising decompressing said compressed frame of video data to generate an image stream.

23. The article of claim 17, comprising a medium storing instructions that, if executed enable a processor-based system to perform steps comprising lowering the resolution of said uncompressed video data to enable a frame-based editing thereof.

24. The article of claim 23, comprising a medium storing instructions that, if executed, enable a processor-based system to perform steps comprising incorporating a sequence of edit commands into said compressed frame of video data to cause said frame-based editing of said uncompressed video data.

25. An image editing device comprising:

an interface to receive an uncompressed digital video signal;

a device operably coupled to said interface to transform the uncompressed digital video signal into a compressed frame of video data; and

an editor operably coupled to said device to receive said compressed frame of video data to generate a command therefrom to cause video editing of said compressed frame of video data.

26. The image editing device of claim 25, said interface to capture said uncompressed digital video signal to derive a stream of frame-based video data.

27. The image editing device of claim 25, said editor to process said compressed frame of video data, wherein said compressed frame of video data to be of a relatively less data density than that of said uncompressed digital video signal.

28. The image editing device of claim 27, said device to generate an edit command to transform said compressed frame of video data.

29. A processor-based system comprising:

an interface to receive an uncompressed digital video signal;

a device operably coupled to said interface to transform the uncompressed digital video signal into a compressed frame of video data; and

an editor operably coupled to said device to receive said compressed frame of video data to generate a command therefrom to cause video editing of said compressed frame of video data.

30. The processor-based system of claim 29, said interface to capture said uncompressed digital video signal to derive a stream of frame-based video data.

31. The processor-based system of claim 29, said editor to process said compressed frame of video data, said compressed frame of video data to be of a relatively less data density than that of said uncompressed digital video signal.

32. The processor-based system of claim 31, said device to generate an edit command to transform said compressed frame of video data.
