Abstract
Method, video encoders, and digital systems are provide in which motion vector determination includes selecting a plurality of candidate motion vectors for a macroblock using a cost function including both a block distortion measure and a motion vector cost measure for single-partition motion vectors in the plurality of candidate motion vectors and using a cost function including a distortion measure without a motion vector cost measure for multi-partition motion vectors in the plurality of candidate motion vectors, and refining the plurality of candidate motion vectors to obtain a refined plurality of candidate motion vectors, wherein multi-partition motion vectors of the plurality of candidate motion vectors are refined using a cost function including a distortion measure without a motion vector cost measure and single-partition motion vectors of the plurality of candidate motion vectors are refined using a cost function including both a block distortion measure and a motion vector cost measure.
