Claim 0:
1. A method for video decoding in a decoder, comprising:
decoding prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of an inter prediction mode;
determining, for each of a plurality of sub-blocks of the current block, a usage of a first (decoder-side motion vector derivation) DMVD process on the respective sub-block of the current block at least partially when a second DMVD process is disabled for the respective sub-block of the current block; and
reconstructing the plurality of sub-blocks of the current block according to the inter prediction mode with the first DMVD process based on the determination for each of the plurality of sub-blocks.
