Original Abstract Submitted

This disclosure relates generally to video coding/decoding and particularly to motion vector prediction based on subblock motion vectors. One method is disclosed for processing a current block of a current frame in a coded video bitstream. The method includes receiving, by a device, a coded video bitstream; determining, by the device based on the coded video bitstream, the current block of the current frame to be inter predicted by at least one reference block of at least one reference frame; determining, by the device based on the coded video bitstream, a current-block motion vector (MV) corresponding to each of the at least one reference block, the current-block MV to be predicted by a reference MV; and identifying, by the device, a subblock MV of a MV reference block as the reference MV for predicting the current-block MV.
