Abstract: A method for refining merge mode motion vector difference (MMVD) prediction is provided. A video coder receives data to be encoded or decoded as a current block of pixels in a current picture of a video. The video coder selects a merge candidate from a plurality of merge candidates to obtain a base motion for the current block. The video coder refines the base motion by performing bilateral matching. The video coder refines each motion candidate by one or more refinement passes. The video coder generates a prediction of the current block by selecting a refined motion candidate. The refined motion candidates may be assigned indices for selection according to costs that are determined by template matching. The video coder encodes or decodes the current block by using the generated prediction.
