This paper proposes a new fast adaptive motion estimation algorithm based on H.264.It uses the statistics of video sequence and the correlation of SADs in the space to early terminate the search,and it determines the search pattern according to the block’s motion activity,proposes a new unsymmetrical synthetic diamond search pattern.Compared to Fast-Full-Search,the PSNR is just 0.017 dB lower and bitrates is 0.45% high while the speed is 15 times up.With same image quality to algorithm in JM,the speed is 35% faster.
