Abstract: A method and apparatus for predicting motion vector for inter-frame encoding are provided. An implementation scheme of the method includes: acquiring first and second sets of motion vectors; dividing, in response to the number of valid adjacent PUs being greater than or equal to a preset number, the second set of motion vectors into at least one motion vector subset; calculating a correlation between the first set of motion vectors and each motion vector subset respectively, to obtain a priority of each adjacent PU; calculating, sequentially according to the priority in descending order, a rate distortion based on a motion vector of each adjacent PU, and stop calculating until a rate distortion smaller than a predetermined threshold is obtained; and determining a motion vector of an adjacent PU used when the rate distortion smaller than the predetermined threshold is obtained as the motion vector of the current PU.
