Abstract
A video coding method includes: obtaining a current frame from a plurality of video frames to be encoded, the plurality of video frames having different resolutions; determining a target motion vector (MV) corresponding to each block in the current frame at a target resolution represented by selected target MV resolution information; obtaining a motion vector prediction (MVP) corresponding to each block and at the target resolution; and encoding the current frame according to a motion vector difference (MVD) between each target MV and the MVP of each block to obtain encoded data. The encoded data includes identification information representing the target resolution.
