In motion estimation, H.264 provides some technologies for increasing precision, i.e. the multiple reference frames technology, variable block size technology and quarter-pixel motion estimation. Unlike other video coding, H.264 can reference more than one reference frame, so it has to pay more computation in motion estimation. In this paper, we proposed an algorithm to select possible frames by the motion cycle of the object in foreground, and then we will search further in these possible frames. Experimental results show our proposed method is more effective in encoding time than, and is similar in PSNR and bit rate to the method proposed by Kuo and Lu.
