Methods and apparatuses for sub-block motion vector prediction
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 decodes prediction information for a current block in a current coded picture that is a part of a coded video sequence. The prediction information indicates whether a planar motion vector prediction mode is used for the current block. The current block is partitioned into a plurality of sub-blocks. When it is indicated that a planar motion vector prediction mode is used for the current block, the processing circuitry determines, in response to the use of the planar motion vector prediction mode, at least one temporal motion vector predictor (TMVP) candidate for a bottom-right (BR) corner of the current block. Then the processing circuitry reconstructs the current block according to one of the at least one TMVP candidate for the BR corner.
