Claim 13:
14. A video processing apparatus comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
partition a video block of a current picture into a first set of sub-blocks according to a first pattern;
partition the video block into a second set of sub-blocks according to a second pattern, wherein at least one sub-block in the second set has a different dimension than a sub-block in the first set; and
determine a prediction block for the video block, wherein the prediction block is a combination of a first intermediate prediction block generated from the first set of sub-blocks and a second intermediate prediction block generated from the second set of sub-blocks,
wherein the partitioning the video block into the first set of sub-blocks is performed for a motion compensation of the video block based on a reference picture in a first reference picture list, and the partitioning the video block into the second set of sub-blocks is performed for the motion compensation of the video block based on a reference picture in a second reference picture list, wherein reference pictures in the first reference picture list are temporally at a different side of the current picture than reference pictures in the second reference picture list.
