MERGING AND SPLITTING OF MEDIA COMPOSITION FILES

摘要

During the production of a time-based media project, it is often desirable for editors to work with media files or reels of a given size, both in terms of the temporal duration of media represented in each file and the number of tracks in a file. During the course of editing, files may become longer, or incorporate additional tracks, making them cumbersome to handle. A super-file view that displays multiple files simultaneously provides a framework for an editor to rebalance files during the course of media production. A graphical user interface permits users to adjust the content of the various files, including moving tracks among multiple files that comprise a given reel, as well as media between files belonging to different reels.

主权项

1. A method of allocating time-based media essence among a set of media essence files that comprise a media composition, each media essence file having a corresponding compositional metadata file, the method comprising:
displaying a graphical representation of the set of compositional metadata files, each compositional metadata file of the set of compositional metadata files representing multiple elements of time-based media essence corresponding to a given time span within the media composition, and wherein a temporal relationship among the time spans of the set of media essence files is reflected in a displayed spatial arrangement of the representation of the compositional metadata files; and enabling a user to interact with the displayed graphical representation of the set of compositional metadata files to:
change time spans of the set of media essence files by adjusting a graphically represented boundary between a pair of compositional metadata files representing media essence files comprising media essence corresponding to temporally adjacent time spans of the media composition; andchange a set of elements within one or more of the media essence files by moving a graphical representation of the set of elements within a first compositional metadata file corresponding to a first time span within the media composition to a second compositional metadata file corresponding the first time span within the media composition.
