Abstract

Some embodiments provide a method for processing metadata associated with digital video in a multi-state video computer readable medium. The method specifies a set of rules for propagating the metadata between different states in the video computer readable medium. It then propagates the metadata between the states based on the specified set of rules.

Claims

1. For a video-editing application, a method for recapturing media items for a composite presentation, the method comprising:

identifying a media item that was previously imported from a first storage to a media-editing application data storage as one of a missing, corrupted, and incomplete media item, wherein the identified media item is part of the composite presentation and associated with a particular duration of the composite presentation;

recapturing the media item from the first storage and storing the recaptured media item in a media file on the media-editing application data storage;

identifying a set of metadata associated with the particular duration of the composite presentation, the set of metadata comprising an associated set of recapture rules; and

storing the identified metadata set with the recaptured media item in the media file when the associated set of recapture rules specifies that the metadata set should be stored with the media item during a recapture operation.

2. The method of claim 1, wherein the set of metadata is a first set of metadata and the set of recapture rules is a first set of recapture rules, the method further comprising:

identifying a second set of metadata associated with the particular duration of the composite presentation, the second set of metadata comprising an associated second set of recapture rules; and

storing the second metadata set with the recaptured media item when the associated second set of recapture rules specifies that the second metadata set should be stored with the media item in the media file during the recapture operation.

3. The method of claim 2, wherein the second set of metadata is not stored with the media item when the second set of rules specifies that the second metadata set should not be stored with the media item during the recapture operation.

4. The method of claim 1, wherein the method is performed by the media-editing application executing on a computer.

5. The method of claim 1 further comprising editing a plurality of different media items to create the composite presentation.

6. The method of claim 1 further comprising storing the recaptured media item in the media file without the identified metadata set when the associated set of recapture rules specifies that the metadata set should not be stored with the media item during the recapture operation.

7. The method of claim 1 further comprising storing the recaptured media item in the media file with a subset of the identified metadata set when the associated set of recapture rules specifies that only the subset of the metadata set should be stored with the media item during the recapture operation.

8. The method of claim 1, wherein a plurality of different sets of metadata is associated with a plurality of different durations of the composite presentation, wherein each set of metadata comprises data that describes media content associated with a corresponding duration of the composite presentation.

9. The method of claim 1, wherein recapturing the media item from the first storage comprises recapturing the media item from a tape and storing the media item in the media file on a disk.

10. The method of claim 9, wherein storing the identified metadata set with the recaptured media item comprises storing the metadata set in the media file on the disk.

11. The method of claim 9, wherein recapturing the media item further comprises linking the media file to the media-editing application data storage.

12. The method of claim 1, wherein the metadata set is stored in a metadata track of the composite presentation and has a start time and an end time in the presentation that correspond to the particular duration.

13. The method of claim 1, wherein the metadata set is stored in a user data element that includes a metadata container and an index that associates the set of metadata with the media item in the composite presentation.

14. A non-transitory computer readable medium storing a computer program executable by at least one processing unit, the computer program comprising sets of instructions for:

identifying a media item that was previously imported from a first storage to a media-editing application as one of a missing, corrupted, and incomplete media item, the identified media item for use in a particular portion of a composite presentation created by the media-editing application;

recapturing the media item from the first storage and storing the recaptured media item in a media file on a second storage local to the media-editing application;

determining whether a particular metadata set associated with the recaptured media item has an associated set of recapture rules for processing the particular metadata set during the recapturing operation;

when the particular metadata set has an associated set of recapture rules, determining whether to store the particular metadata set in the media file according to the associated set of recapture rules; and

when the particular metadata set does not have an associated set of recapture rules, storing the particular metadata set in the media file with the recaptured media item.

15. The non-transitory computer readable medium of claim 14, wherein the computer program further comprises sets of instructions for, when the particular metadata set has an associated set of recapture rules:

storing the particular metadata set in the media file with the recaptured media item when the associated set of recapture rules specifies to store the particular metadata set; and

storing the recaptured media item in the media file without the particular metadata set when the associated set of recapture rules specifies the particular metadata set should not be stored with the recaptured media item.

16. The non-transitory computer readable medium of claim 14, wherein the particular metadata set comprises information about a creation of the media item.

17. The non-transitory computer readable medium of claim 14, wherein the computer program further comprises a set of instructions for editing, in the media-editing application, a plurality of different media items to create the composite presentation.

18. The non-transitory computer readable medium of claim 14, wherein the associated set of recapture rules is organized in an XML document.

19. A non-transitory computer readable medium storing a computer program executable by at least one processing unit, the computer program comprising sets of instructions for:

identifying a media item that was previously imported for a composite media presentation as one of a missing, corrupted, and incomplete media item;

recapturing the media item for use in a particular portion of the composite media presentation, the particular portion having an associated set of metadata that comprises a set of recapture rules;

identifying, based on the set of recapture rules for the set of metadata, a subset of the associated set of metadata to store with the recaptured media item; and

storing the identified subset of the metadata set with the recaptured media item.

20. The non-transitory computer readable medium of claim 19, wherein the media item is a first media item, the particular portion is a first portion, the set of metadata is a first set of metadata, and the set of recapture rules is a first set of recapture rules, wherein the computer program further comprises sets of instructions for:

identifying a second media item that was previously imported for the composite media presentation, as one of a missing, corrupted, and incomplete media item;

recapturing the second media item for use in a second portion of the composite media presentation, the second portion having an associated second set of metadata that comprises a second set of recapture rules;

identifying, based on the second set of recapture rules, a subset of the second set of metadata to store with the second recaptured media item; and

storing the identified subset of the second metadata set with the second recaptured media item.

21. The non-transitory computer readable medium of claim 19, wherein the computer program further comprises a set of instructions for editing a plurality of different media items to create the composite media presentation.

22. The non-transitory computer readable medium of claim 19, wherein the particular portion has an associated second set of metadata that comprises a second set of recapture rules, wherein the computer program further comprises sets of instructions for:

identifying, based on the second set of recapture rules for the second set of metadata, a subset of the associated second set of metadata to store with the recaptured media item; and

storing the identified subset of the second metadata set with the recaptured media item.
