Abstract
A multitrack architecture for computer-based editing of multimedia sequences is disclosed herein. The multimedia sequences are formed of a plurality of collated segments representing audio or video scenes. The architecture contains sequence tracks for ordering the segments of the multimedia sequence and process tracks for applying transformations and/or animations to some of these segments. The output of the process tracks may be supplied to other process tracks and/or to a sequence track. Scope controls are provided to determine which portion of the output of a process track is supplied to another process track and/or to a sequence track.
