A frame prediction system and a prediction method thereof. An initializing module initializes a first image block having a plurality of pixels. A providing module provides a first centroid and a first motion vector of a second image block. The location lookup module finds a location according to the first centroid, and generates a first weight and a second weight respectively according to a relationship between each of the pixels, the first centroid and the location. A vector lookup module finds a second motion vector, which gives a minimum pixel intensity error for the plurality of pixels in the first image block according to the first centroid, the first motion vector, the location, the first weight and the second weight. A processing module sequentially calculates a plurality of predictive intensity values according to the motion vectors and the weights.

A video encoding method is provided in the invention. In such method, after a current encoding frame among a sequence of input frames is received, each coding unit in the current encoding frame may be optionally split into two oblong prediction units, and each of the prediction units may be optionally split into a plurality of sub-blocks so as to thereby improve the matching accuracy for a matching reference block from a reference frame. A video decoding method corresponding to the aforesaid video encoding method is also provided.
