Abstract
A method, apparatus, and article of manufacture for traversing a process tree in a digital video editing system. A process tree is loaded into a digital video-editing system. The process tree has parent nodes that are dependent on output data from child nodes. Each parent node and each child node represents a digital video processing task to be performed during a traversal of the process tree. Each parent node declares a data definition and data default values. The data definition defines a structure of the data used by that parent node. For each parent node processed, a determination is made regarding whether the data definition for the output data received from a dependent child node is compatible with the data definition declared for that parent node. If the data definition is incompatible, the parent node utilizes the data default values.
