Abstract:
Systems, methods and computer readable mediums are presented for encoding a stream of input video frames, in which the input video frames are down sampled and the down sampled frames are encoded in a first encoding pass to generate a set of first pass coded frames forming a single first pass I frame and a plurality of first pass P frames formed into first pass sub-groups of pictures (SUB-GOPs). First pass encoding statistics are generated for individual first pass SUB-GOPs, and the statistics are used to encode the input video frames in a second encoding pass to generate a set of second pass coded frames.

Claim (Index 7):
The method of  claim 1 ,\n wherein the second pass SUB-GOPs individually including at least one second pass bipredictive coded frame (B frame) that includes motion-compensated difference information relative to two other second pass coded frames; wherein generating the first pass encoding statistics for individual first pass SUB-GOPs of the first pass P frames includes computing an integer number N first pass mean motion vectors individually corresponding to the individual first pass P frames; and wherein encoding the input video frames in the second encoding pass includes:\n scaling the first pass motion vectors according to an amount of down sampling performed on the video frames of the first video stream to generate scaled first pass motion vectors, \n for the individual second pass B frames of the individual second pass SUB-GOPs, computing a second pass mean motion vector according to the scaled first pass mean motion vectors for the first pass coded frames to which the individual B frame is referenced and any intervening first pass coded frames, and \n for the individual second pass P frames of the individual second pass SUB-GOPs, computing a second pass mean motion vector as a cumulative sum of the scaled first pass mean motion vectors for the first pass coded frames of the corresponding second pass SUB-GOP.
