Abstract
A method and apparatus are described for performing video encoding mode decisions. A down-scaled frame is received that includes a macroblock corresponding to a first subset of macroblocks of a first area in a full-scale frame. A first average motion vector is calculated for the first subset of macroblocks, and a second average motion vector is calculated for a second subset of macroblocks of a second area surrounding the first subset of macroblocks. A comparison of a threshold to a distance measure between absolute values of the first and second average motion vectors is performed. A prediction mode for the macroblock in the down-scaled frame is determined based on the comparison to generate predicted blocks.
