Abstract

A device for decoding video data can be configured to determine that a block of the video data is coded in an affine prediction mode; determine a plurality of control point motion vectors (CPMVs) for the affine prediction mode; perform two or more DMVR processes on the CPMVs to determine two or more sets of refined CPMVs, wherein to performing the two or more DMVR processes on the CPMVs to determine the two or more sets of refined CPMVs, the one or more processors are further configured to perform two or more of bilateral matching-based affine DMVR, regression-based DMVR, affine model parameter refinement, affine DMVR CPMV searching, or affine DMVR CPMV search refinement; perform a cost comparison between the two or more DMVR processes to select a set of refined CPMVs from the refined CPMVs; and determine a prediction block for the block based on the set of refined CPMVs.
