MOTION PREDICTION BASED ON UPDATED MOTION VECTORS

摘要

A method for video processing, comprising: determining a current block is associated with a first and second reference motion vectors; generating updated first and second reference motion vectors based on a sum of a scaled first motion refinement and the first and second reference motion vectors, respectively, wherein the first motion refinement is derived based on a bi-directional optical flow mode; and performing, based on the updated first and second reference motion vectors, a conversion between the current video block and a bitstream representation of a video data including the current block.
