US Patent 11470341 Interaction between different DMVD models

Apparatus and methods for video processing are described. An exemplary method for video processing includes: determining non-updated motion information associated with a current block; updating the non-updated motion information based on multiple decoder-side motion vector derivation (DMVD) methods to generate updated motion information for the current block; and performing, based on the updated motion information, a conversion between the current block and a bitstream representation of a video including the current block.
