Abstract
A system and method for increasing the performance of a compositing system when compositing images represented as a directed acyclic graph. The method comprises identifying at least one critical path, determining a set of input nodes to each critical path, and caching the images at each of the input nodes to each critical path. The critical paths may comprise all nodes between and including the edit nodes on one end and the view node at another end. The method may also include receiving a user designation of at least one view node and at least one edit node, receiving a request to view the video presentation at a view node, processing data at the view node responsive to the request, and displaying the video presentation at the view node. Caching may be implemented when processing nodes such that when processing a node, a determination is made whether the node is an input node to one of the critical paths. If a node is an input node to one of the critical paths, the cache memory is checked to determine if the node is already cached. If the node is cached, the node is retrieved from cache memory; if the node is not in the cache, the node is processed and the resulting data is cached.
