Abstract
Aspects of the disclosure include a method for video decoding that includes receiving coding information for a block indicating that the block is coded with a joint motion vector difference (JMVD) coding mode and a compound weighted prediction mode and includes scaling factor information of the JMVD coding mode. When the scaling factor information indicates that each scaling factor of vertical and horizontal components of a plurality of MVDs associated with respective reference frames of the block is 1, the method includes determining a weighting factor of the compound weighted prediction mode based on a weighting factor index signaled in a bitstream and a list of weighting factors. The method includes determining, using the JMVD coding mode, motion information associated with the respective reference frames based on the scaling factors and reconstructing, using the compound weighted prediction mode, the block based on the motion information and the determined weighting factor.
