The multiple reference frame motion compensation (MRMC) supported by H.264 makes use of redundancy between multiple frames to enhance the coding efficiency over the techniques which use a single reference frame motion compensation. However, searching the motion vectors in multiple frames is computationally expensive. This paper proposes a smart MRMC selection technique, which has a lower search complexity without sacrificing video quality. To reduce the complexity of the motion estimation process, adaptive block size phase correlation motion estimation (ABS-PC-ME) technique using several prediction techniques is used. The proposed scheme has lower complexity compared with the conventional schemes.
