Abstract

Some embodiments provide a method for defining a data structure for representing a media file imported into a media-editing application. The method defines a reference to an original version of a media file. The method defines references to one or more transcoded versions of the media file. Each of the transcoded versions has a different resolution. The method defines a set of metadata storing information regarding the media file. In some embodiments, the media file includes both audio and video. The method defines a video clip data structure for the media file that references the first data structure and an audio clip data structure for the media file that also references the asset data structure. The method defines a media clip data structure that contains the video clip data structure and the audio clip data structure. The media clip data structure is for editing into a composite video presentation.

Claims

1. A method for defining a data structure for representing a media file imported into a media-editing application, the method comprising:

defining a reference to an original version of a media file;

defining references to one or more transcoded versions of the media file, each of the transcoded versions having a different resolution; and

defining a set of metadata storing information regarding the media file.

2. The method of claim 1, wherein the method further comprises defining a references to one or more analysis data files that store analysis data generated for the media file.

3. The method of claim 2, wherein the analysis data comprises color balancing data for images of the media file.

4. The method of claim 2, wherein the analysis data comprises shake detection data that comprises (i) data indicating whether the media file comprises images captured by a shaking camera and (ii) data defining how to correct the shake.

5. The method of claim 2, wherein the analysis data comprises data indicating the presence of people in images of the media file.

6. The method of claim 1, wherein the transcoded versions of the media file comprise versions of the media file optimized for editing.

7. The method of claim 1, wherein the data structure is a first data structure, the method further comprising defining a second data structure for a media clip that references the first data structure.

8. The method of claim 7, wherein the first and second data structures are defined within a third data structure that contains data structures for a plurality of different media files.

9. The method of claim 7, wherein the media file comprises both audio and video and the second data structure is for a video clip, the method further comprising defining a third data structure for an audio clip that references the first data structure.

10. The method of claim 1, wherein the data structure is defined upon import of the media file into the media-editing application.

11. A computer readable medium storing a media editing application for execution by a processor, the media editing application comprising sets of instructions for:

upon import of a media file comprising media content, generating (i) a low-resolution version of the media content and (ii) a high-resolution version of the media content;

storing (i) a copy of the media file in a first folder in a particular file structure along with additional original media, (ii) the low-resolution version of the media content in a second folder in the particular file structure along with additional low-resolution versions of media content, and (iii) the high-resolution version of the media content in a third folder in the particular file structure along with additional high-resolution versions of media content.

12. The computer readable medium of claim 11, wherein the first folder, second folder and third folder are sub-folders of a fourth folder.

13. The computer readable medium of claim 11, wherein the second folder and third folder are sub-folders of a fourth folder, and the first folder and the fourth folder are sub-folders of a fifth folder.

14. The computer readable medium of claim 11, wherein the computer program further comprises sets of instructions for:

analyzing the media file to generate at least one analysis data file storing data about the media file; and

storing the analysis data file in a fourth folder in the particular file structure along with additional analysis data files storing information about other media content.

15. The computer readable medium of claim 11, wherein the copy of the media file, the low-resolution version of the media file, and the high-resolution version of the media file all have the same file name.

16. The computer readable medium of claim 11, wherein the computer program further comprises sets of instructions for creating a data structure that represents the media file in the media-editing application, the data structure comprising references to the copy of the media file, the low-resolution version of the media file, and the high-resolution version of the media file.

17. A method for defining a set of data structure for a media file imported into a media-editing application, the media file comprising both audio and video, the method comprising:

defining a first asset data structure for the media file, the asset data structure comprising references to at least one version of the media file;

defining a video clip data structure for the media file that references the asset data structure;

defining an audio clip data structure for the media file that also references the asset data structure;

defining a media clip data structure that contains the video clip data structure and the audio clip data structure, the media clip data structure for editing into a composite video presentation.

18. The method of claim 17, wherein the media clip data structure comprises an array containing the video clip data structure.

19. The method of claim 18, wherein the audio clip data structure is anchored to the video clip data structure within the media clip data structure such that the audio and video clips are edited in unison.

20. The method of claim 17 further comprising defining a sequence data structure containing the media clip data structure, wherein the sequence data structure comprises a plurality of video properties metadata.

21. The method of claim 17 further comprising:

receiving instructions to add the media clip to a composite presentation;

duplicating the media clip data structure, including the video and audio clip data structures that reference the asset data structure;

adding the duplicated media clip data structure to a second media clip data structure that comprises a plurality of media clip data structures to define the composite presentation.

22. The method of claim 21, wherein the duplicated media clip data structure is anchored to a third media clip data structure within the second media clip data structure.
