In this paper, we analyze the bit rate distribution of the full search and the fast search motion estimation algorithms in H.264. It shows both experimentally and theoretically that a well-designed fast block-matching algorithm not only speeds up motion estimation process, but also improves the rate-distortion performance. This is in contrast to the common belief that full search always yields optimal rate-distortion performance under the same test condition.
