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 receives a video bitstream including a current block, and determines a candidate list that includes a plurality of motion vector (MV) candidates for predicting the current block. The processing circuitry modifies the plurality of MV candidates in the candidate list according to a motion information based diversity assessment of the plurality of MV candidates. The modifying the plurality of MV candidates prioritizes a subset of MV candidates with a larger difference in motion information. The processing circuitry decodes, from the video bitstream, an index indicating a selected MV candidate from the modified candidate list, and reconstructs the current block based on the selected MV candidate.
