1. A method, comprising:
generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV1) and a 0-phase motion vector (MV0), each MV1 and MV0 having an associated depth value, to thereby form an MV1 texture and an MV0 texture;
converting the MV1 texture to a set of MV1 blocks and converting the MV0 texture to a set of MV0 blocks; and
outputting the set of MV1 blocks and the set of MV0 blocks for image processing.
