ABSTRACT:
A method for encoding video, comprising the steps of (A) encoding a number of frames of a video signal using a first sub-set of encoding parameters, (B) analyzing the encoded frames to find and mark reference frames that are used more than a predetermined number of times, and (C) re-encoding the video signal using a second sub-set of encoding parameters different than the first sub-set of encoding parameters when re-encoding the marked reference frames.
