The embodiment of the present invention provides a video encoding method, decoding method and apparatus, applied to the field of signal processing and can improving video decoding performance and enhancing decoding accuracy. The video decoding method is applied to a decoder and comprises: acquiring N pieces of motion information of a target area according to motion related information in a code stream generated by an encoder, the N being an integer greater than or equal to 2; using each of the N pieces of motion information to carry out a motion compensation operation on the target area to obtain N predictions of the target area, each of the N predictions of the target area comprising predicted values of all sampling points in the target area; acquiring prediction selection references of the target area, the prediction selection references of the target area being values of all sampling points in a reference area corresponding to the target area; and determining a final prediction of the target area according to the N predictions of the target area and the prediction selection references of the target area. The video encoding method, decoding method and apparatus provided by the present invention are used for video encoding and decoding. |
