Abstract
A video coding method includes obtaining a current frame from a plurality of video frames, from which at least two or more video frames from have different resolutions; determining an initial motion vector (MV) corresponding to each block to be encoded in the current frame at a corresponding resolution; and determining a target MV resolution according to a resolution configuration of the current frame to represent a target resolution. The method also includes determining a target MV corresponding to each block in the current frame at the target resolution represented by the target MV resolution; obtaining a motion vector prediction (MVP) corresponding to each block in the current frame at the target resolution; and encoding the current frame according to a motion vector difference (MVD) between each target MV and the corresponding MVP such that the MV and the corresponding MVP are at a same resolution.
