Abstract

The video decoder may be configured to determine that a current block in a current picture of video data is coded in an affine prediction mode, determine one or more control point motion vectors (CPMVs) for the current block, identify an initial predictive block for the current block in a reference picture using the one or more CPMVs, determine a current template for the current block in the current picture, determine an initial reference template for the first predictive block in the reference picture, and perform a motion vector refinement process to determine a modified predictive block based on a comparison of the initial reference template and the current template.
