Abstract
A video processing method includes obtaining motion information of a left neighboring block of a current image block, and, where the left neighboring block satisfies a condition, determining, in a collocated frame of the current image block, a related block of a sub-block of the current image block using a motion vector of the left neighboring block as a motion offset, and determining a motion vector of the sub-block according to a motion vector of the related block. The preset condition includes a reference image of the left neighboring block being same as the collocated frame of the current image block. Determining the motion vector of the sub-block includes, where reference images of the related block and the sub-block are not specific reference images, determining the motion vector of the sub-block according to a scaled motion vector obtained by scaling the motion vector of the related block.
