1. A video image processing method comprising:
determining a group of control point motion vectors in an affine transformation mode using one or more neighboring blocks of the current image block;
adding the group of control point motion vectors to a motion vector candidate list of the current image block;
dividing a current image block into a plurality of sub-blocks;
in response to a target neighboring block of the current image block satisfying a preset condition, determining related blocks of the sub-blocks in a collocated frame of the current image block according to a motion vector of the target neighboring block; and
encoding or decoding the current image block according to motion vectors of the related blocks of the sub-blocks.
