Multimedia file format
An automatically readable medium encoded with a time-based media file which comprises a factory object which uniquely identifies the instantiation of an object of a particular type. The factory object can be one of the following: a scene object; a behavior object; or a filter object. The scene object can include at least one of the following: global setting for the scene; or the last settings used to render to a resulting time-based media file. The scene object can ultimately contain a reference to media used by the object. A scene object can include a reference to another scene object.
1. A computer-readable medium encoded with a time-based media file comprising a factory object which uniquely identifies the instantiation of an object of a particular type wherein said factory object is one of the following:
an object that represents a scene, wherein the scene object comprises a reference to media used by the scene object;
an object that represents a behavior; or
an object that represents a filter.
2. The computer-readable medium of claim 1 wherein said scene object includes at least one of the following:
global setting for the scene; or
last settings used to render to a resulting time-based media file.
3. The computer-readable medium of claim 1 wherein said scene object includes another scene object.
4. A computer-readable data structure, encoded on a computer-readable medium, for representing a multimedia file comprising factory objects which uniquely identify the instantiation of an object of a particular type, the structure comprising:
factory descriptions for describing factory objects;
an object that represents a scene, wherein the scene object comprises a reference to media used by the scene object; and
settings for user interface parameters specifying how the scene object is displayed.
5. The data structure of claim 4 , wherein the settings for the user interface parameters are readable by user interface elements comprising at least one of a viewer, project panel, timeline, curveeditor, and audioeditor for presentation to a user.
6. The data structure of claim 4 , wherein the settings for the user interface parameters are writeable by user interface elements comprising at least one of a viewer, project panel, timeline, curveeditor, and audioeditor.
7. The data structure of claim 4 , wherein the scene object comprises at least one of audio tracks, scene settings, export settings, layers, and footage used in the scene.
8. The data structure of claim 7 , wherein the scene settings comprise global settings for a scene.
9. The data structure of claim 7 , wherein the scene settings comprise last settings used to render to a resulting multimedia file.
10. The data structure of claim 4 , wherein a factory description comprises an image.
11. The data structure of claim 4 , wherein a factory description comprises a master.
12. The data structure of claim 4 , wherein a factory description comprises a throw.
13. The data structure of claim 4 , wherein a factory description comprises a filter.
14. The data structure of claim 7 , wherein the export settings specify a multimedia format for viewing a resulting multimedia file.
15. The data structure of claim 14 , wherein the multimedia format comprises a QuickTime format.
16. The data structure of claim 7 , wherein the layers comprise scene objects.
17. The data structure of claim 7 , wherein the layers comprise filter objects.
18. The data structure of claim 7 , wherein the layers comprise behavior objects.
19. The data structure of claim 4 , wherein the scene object is associated with a behavior.
20. The data structure of claim 4 , wherein the scene object is associated with a filter.
21. The data structure of claim 19 , wherein the behavior comprises a throw behavior.
22. The data structure of claim 20 , wherein the filter comprises a contrast filter.
23. The data structure of claim 7 , wherein the footage can be used by multiple scene objects.
24. The data structure of claim 4 , wherein the user interface parameters are organized hierarchically.
25. A method for processing a multimedia data file, the method comprising:
reading a multimedia data file organized according to a data structure comprising:
factory descriptions for describing factory objects;
an object that represents a scene, wherein the scene object comprises a reference to media used by the scene object; and
settings for user interface parameters specifying how the scene object is displayed;
parsing the data file according to the data structure; and
displaying the data file.
26. A computer program product comprising:
a computer-readable medium having computer program code embodied therein for processing a multimedia data file, the computer program code adapted to:
read a multimedia data file organized according to a data structure comprising
factory descriptions for describing factory objects;
an object that represents a scene, wherein the scene object comprises a reference to media used by the scene object; and
settings for user interface parameters specifying how the scene object is displayed;
parse the data file according to the data structure; and
display the data file.
