Abstract
Systems, devices, and methods of performing inter-frame prediction in video compression. A method includes: partitioning a video frame into superblocks, each superblock includes a plurality of macroblocks; determining an upper boundary on attributes that are associated with residual blocks of the plurality of macroblocks, based on pre-defined constraints on the total number of bits allocated for motion vector descriptions in a superblock; for each macroblock in a superblock, determining a partition size and a motion vector resolution which yield, for all macroblocks in the superblock, a motion vector description and a corresponding residual with attributes less than or equal to the upper boundary.
