A motion vector (MV) prediction method and a prediction apparatus thereof are applicable for a video image encoder/decoder to predict an MV of a video image. Firstly, segment a macroblock in the video image into microblocks. Then, configure a row memory and three register memories to register the MV required for prediction. Finally, the MV stored in the row memory or the register memories at a position corresponding to the current microblock to be predicted is used to predict the MV of the current microblock to be predicted in the current macroblock to be predicted. After the prediction is completed and moved to another macroblock or microblock, the MV stored in the row memory or the register memories is updated according to a predetermined storage updating condition.
