Abstract: The new features of H.264 coding technology are introduced and analyzed , and the traditional algorithm of mode selection in video coding is also considered. The paper suggests a new algorithm based on H.264, which refers to combining the PMVFAST motion estimation and fractional pixel accuracy fast method with the preceded coding mode info to decide reasonably the next predicting mode or end the prediction procedure in time.
