Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry. The processing circuitry extracts (e.g., parses), from a bitstream, affine merge with motion vector difference (MMVD) candidate information for a current block in a current picture. The processing circuitry determines a first MV refinement offset associated with a first control point motion vector (CPMV) of an affine MMVD candidate. The processing circuitry derives at least a first refined motion vector (MV) value associated with the affine MMVD candidate according to the affine MMVD candidate information and the first MV refinement offset. The processing circuitry reconstructs a sample of the current block according to at least a first reference sample in a first reference picture, the first reference sample is indicated by the first refined MV value.
