Abstract
Frames of a video stream can be partitioned using source difference variance based partitioning before encoding. Variances between blocks of a current video frame and blocks of a previous unencoded video frame are determined. The current video frame can be partitioned into varying block sizes depending upon the magnitude of the variances. Blocks with low variance may be combined with other low variance blocks to form larger blocks, while blocks with high variance may be further partitioned into smaller blocks to improve encoding efficiency of the blocks. In cases where partitioning of a frame is unlikely to provide improved efficiency, the variation calculations may be skipped in favor of using fixed partitioning.
