Abstract

Complexity for a video frame after a special event is estimated and used for encoding the frame. The complexity for a key frame of a special event is estimated based on its intra activity and a complexity of a previously encoded key frame in the video stream prior to the special event. The complexity for a dependent frame after a special event is estimated based on a motion estimation cost for the dependent frame and a complexity of a previously encoded dependent frame prior to the special event.
