Claim:
1. A motion refinement section for use in a video processing device that processes a video input signal that includes a plurality of pictures each having a plurality of macroblock pairs, the motion refinement section comprising: a partition subset selection module that, when a macroblock adaptive frame and field indicator indicates a macroblock adaptive frame and field mode is selected, generates a selected subset of partitions of a macroblock pair of the plurality of macroblock pairs as a first subset of available partitions, and when the macroblock adaptive frame and field indicator indicates the macroblock adaptive frame and field mode is deselected, generates the selected subset of partitions as a second subset of available partitions, wherein the first subset is different from the second subset; and a motion refinement module, coupled to the partition subset selection module, that generates refined motion vectors for the macroblock pair, based on the selected subset of partitions for a macroblock pair, by refining motion search motion vectors for the macroblock.
