Abstract
A method of video processing is provided to include determining, for a conversion between a current video block of a video and a coded representation of the video, a mode of operation of an UMVE mode; and performing the conversion based on the determining, wherein the current video block is coded with a merge mode and motion vector differences in an UMVE mode that comprises a motion vector expression that includes a starting point of motion information, a motion magnitude and a motion direction for the current video block, and wherein one or more fields in the coded representation correspond to the mode of operation, and wherein the one or more fields include: a list size field that indicates a size of a base candidate list used by the UMVE mode, or a table field that signals a distance table or a direction table for the UMVE mode.
