1. A method for video image compression tangibly embodied on a video image compression system, the method comprising: providing a sequence of frames having picture regions, the frames having predicted frames and referenceable frames; and encoding a picture region of at least one predicted frame with an encoder by reference to two or more referenceable frames in the sequence, wherein said encoding comprises encoding using an unequal weighting of selected picture regions from said two or more referenceable frames, wherein said unequal weighting comprises a function of a temporal distance to each of the two or more referenceable frames from at least the one predicted frame, wherein each of said frames comprises pixel values arranged in macroblocks.
