Abstract

Methods, graphical user interfaces, computer apparatus and computer readable medium for merging different versions of multimedia project (e.g., movie) are disclosed. For example, modifications separately and concurrently made to multimedia assets of a multimedia project in production can be efficiently and intelligently merged. The multimedia assets can be audio, video or graphical elements.

7. A computer-implemented method as recited in claim 5, wherein said identifying (e) of the change region information identifies contiguous regions of clips that have been deleted or moved between the first and second sequences.

8. A computer-implemented method as recited in claim 7, wherein when a particular clip has been added to the first sequence as compared to the base sequence, the change region information determines the proposed positioning for the particular clip in the resultant sequence.

9. A computer-implemented method as recited in claim 1,

wherein said method further comprises (e) analyzing media content used with at least one of the clips to provide media content information, and

wherein said determining (c) of the probable placement of at least a plurality of clips from the first sequence and the second sequence for the resultant sequence is based on not only the categorizations of the clips but also the media content information.

10. A computer-implemented method as recited in claim 1, wherein said categorizing (b) of the clips comprises:

selecting a particular one of the clips in the base sequence;

obtaining a unique identifier for the selected clip;

identifying one or more clips in the first sequence that include the unique identifier associated with the selected clip; and

categorizing the one or more identified clips into one of each of the predetermined categories.

11. A computer-implemented method as recited in claim 10, wherein the predetermined categories include same, modified, added and deleted.

12. A computer-implemented method as recited in claim 1, wherein multiple possible placements are identified for at least a plurality of the clips in the resultant sequence.

13. A computer-implemented method as recited in claim 12, wherein a confidence is calculated for each of the identified possible placements.

14. A computer-implemented method as recited in claim 13, wherein at least one clip in the resultant sequence is identified as having a conflict if one of the identified possible placements does not have a substantially higher confidence than the other possible placements.

15. A computer-implemented method as recited in claim 12, wherein said method further comprises:

(e) receiving a user input of one of the identified possible placements.

16. A computer-implemented method as recited in claim 15, wherein said method further comprises:

(f) recalculating possible placements for the clips in response to receiving the user input of one of the identified possible placements.

17. A computer-implemented method as recited in claim 1, wherein said categorizing (b) of the clips comprises:

selecting a particular one of the clips in the base sequence;

matching one or more of the clips in the first sequence and/or the second sequence to the selected clip in the base sequence; and

categorizing the one or more identified clips into one of each of the predetermined categories based on said matching.

18. A computer-implemented method as recited in claim 17, wherein said matching is based on unique identifiers associated with the clips.

19. A computer-implemented method as recited in claim 17, wherein said matching is based on a heuristic comparison of properties of the clips.

20. A computer-implemented method as recited in claim 19, wherein the properties include at least two of start time, length, offset, and media.

21. A method for merging changes made with respect to a first sequence of digital media elements and a second sequence of digital media elements into a resultant sequence of digital media elements, the first sequence and the second sequence being derived from a base sequence, said method comprising:

categorizing each digital media element in the first sequence into one of a set of predetermined categories in relationship to the base sequence;

categorizing each digital media element in the second sequence into one of a set of predetermined categories in relationship to the base sequence; and
