Original Abstract Submitted
in one example, a video encoder divides a superblock of a video frame into subblocks. the dividing includes dividing the superblock according to a first and second partitioning schemes to generate a first and second combination of subblocks, respectively. the number of non-zero residuals in each subblock in the first and second combinations of subblocks is less than a corresponding threshold set for a size of the subblock. the encoder determines the subblocks for the superblock as the first combination of subblocks based on a first cost value associated with the first combination of subblocks being lower than a second cost value associated with the second combination of subblocks. the encoder further encodes the superblock into a video bitstream representing the video by encoding the subblocks.
