Abstract:
1. A method, comprising: computing on a transcoding system a threshold based on an average sum of absolute residual (SAR) values and a standard deviation, each SAR corresponding to the sum of absolute values of the residual signal of a non-intra encoded macroblock in a frame of a first video stream encoded according to a first video specification; decoding on the transcoding system the macroblocks of the frame; comparing on the transcoding system a SAR of one of the macroblocks to the threshold, the one of the macroblocks having a first motion vector; and providing from the transcoding system the first motion vector for encoding the one of the macroblocks according to a second video specification if the SAR of the one of the macroblocks is less than the threshold.
