Original Abstract Submitted
Aspects of the disclosure provide methods and apparatuses for video coding. A method for video decoding includes receiving a coded video bitstream that includes prediction information of a current block in a current picture. The prediction information indicates that an adaptive motion vector prediction (AMVP) mode and an adaptive motion vector resolution (AMVR) mode are applied to the current block. A set of motion vector (MV) resolutions in the AMVR mode is available for the current block. The method includes determining respective template matching (TM) costs corresponding to each of a plurality of MV resolutions in the set of MV resolutions based on the plurality of MV resolutions and motion information of the current block, reordering the plurality of MV resolutions based on the determined TM costs, selecting an MV resolution from the reordered plurality of MV resolutions, and reconstructing the current block based on the selected MV resolution.
