H.264/AVC defined in profile has various characteristics and better coding efficiency than other standards. Its encoding time, However, has increased and complexity has also increased much more by deciding optimal coding mode as variable block size and carrying out motion estimation. This paper propose the method of adaptive block mode to reduce the loss time and setting up search range with reducing the video quality in the process of coding. We examined PSNR and motion estimation time in order to measure both degradation of video-quality and computation. As a result, this method showed that average coding time is shortened as 400~500ms in every frame in the case of all experimented videos, keeping video quality nearly similar, compared to existing full search algorithm.
