Abstract
A video coder is configured to receive a first block of video data to be coded using adaptive affine decoder side motion vector refinement (DMVR). The video coder may determine to set a first motion vector difference (MVD) for a first reference picture list to zero, and then refine control point motion vectors (CPMVs) associated with a second reference picture list to generate refined CPMVs. The video coder may then code the first block of video data using the refined CPMVs.
