Abstract
A system method and computer program product for creating a composited video frame sequence for an application. A current scene state for the application is compared to a previous scene state wherein each scene state includes a plurality of objects. A video construction engine determines if properties of one or more objects have changed based upon a comparison of the scene states. If properties of one or more objects have changed based upon the comparison, the delta between the object's states is determined and this information is used by a fragment encoding module if the fragment has not been encoded before. The information is used to define, for example, the motion vectors for use by the fragment encoding module in construction of the fragments to be used by the stitching module to build the composited video frame sequence.
