Abstract
Scene changes that are done pleasingly and without user input or control. Based on the number of speakers and changes in speakers, either to a different individual or movement by the same speaker, based on the locations of the speakers and based on the overlap of the current and intended scenes, a decision is made whether to perform a smooth transition or do a cut. It has been determined that the decision on cut versus smooth transition is preferably based on the location of the center of the intended new scene versus the boundaries of the current scene, a cut used if the center is outside the boundaries and a smooth transition if inside. If a smooth transition, an easing function, such as ease in ease out, is performed to change the scene. A preferred value for the smooth transition is to perform the transition over 80 frames.
