Current partition checking starts from small sizes, and then goes up to large sizes. This experiment uses the small partitions' motion estimation result, which is already available, to speed up the large partition's motion estimation. We can decide to skip some patition checkings if they are unlikely choices. We could use the motion vector(MV) result as current partition's prediction MV, limit the search range and reference frame. Current result at speed 1: psnr loss: 1.19% for stdhd, 0.287% for derf. speed gain: 14% for sunflower(hd), 11% for akiyo. Further improvement will be done later.
