Abstract
A video image processing method includes dividing a coding tree unit into one or more coding units using a quadtree plus binary tree division method, obtaining a motion vector candidate list of one of the one or more coding units, determining a base motion vector according to motion vectors in the motion vector candidate list, in response to the base motion vector pointing to a short-term reference image, scaling the base motion vector using a scaling factor not equal to 1, in response to the base motion vector pointing to a long-term reference image, scaling the base motion vector using a scaling factor set to 1, and performing prediction for the one of the one or more coding units according to the base motion vector after being scaled.
