Abstract
Motion compensation along different directions is disclosed. A method for video processing includes determining, for a conversion between a current video block of a video and a bitstream representation of the current video block, optical flow associated with the current video block in an optical flow-based motion refinement process or prediction process. The optical flow is derived along directions that are different from a horizontal direction and/or a vertical direction. The method also includes performing the conversion based on the optical flow.
