FAST ALGORITHMS FOR ADAPTIVE MOTION VECTOR RESOLUTION IN AFFINE MODE

摘要

A method for video processing is provided. The method includes determining, based on a coding mode of a parent coding unit of a current coding unit that uses an affine coding mode or a rate-distortion (RD) cost of the affine coding mode, a usage of an adaptive motion vector resolution (AMVR) for a conversion between a coded representation of a current block of a video and the current block; and performing the conversion according to a result of the determining.
