Abstract
A system for video compositing is comprised of a storage device for storing a composite timeline file. A timeline manager reads rendering instructions and compositing instructions from the stored file. A plurality of filter graphs, each receiving one of a plurality of video streams, renders frames therefrom in response to the rendering instructions. 3D hardware is responsive to the rendered frames and the compositing instructions for creating a composite image. A frame scheduler is responsive to the plurality of filter graphs for controlling the frequency at which the 3D hardware creates a new composite image. An output is provided for displaying the composite image. Methods of generating a composite work and methods of generating the timeline file are also disclosed. Because of the rules governing abstracts, this Abstract should not be used to construe the claims.
