ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for determining validity of cached frames of a compositing hierarchy as a composition tree of a digital video composition is edited. The techniques use interval lists associated with nodes in a compositing tree to determine which cached frames of a composition hierarchy are guaranteed to be valid in the face of arbitrary edits to the hierarchy.
