When video noise increases, the coding efficiency of the H.264/AVC considerably decreases. Therefore, we propose a novel mode decision algorithm based on early macroblock-level motion detection. According to the macroblock motion levels, four different mode decision strategies are chosen for current macroblock coding. Experimental results show that the proposed algorithm can significantly reduce the encoding time with similar coding efficiency when weighed up against the H.264/AVC.
