The latest under development video coding standard, H.264, uses multiple reference frames to improve the rate-distortion performance. However, the motion estimation process involved is computational intensive and increases linearly with the number of allowed reference frames. In this paper, a novel fast multi-frame selection method is proposed for H.264 video coding. The proposed scheme can efficiently reduce the computational cost up to 70% with similiar quality and bit-rate. So the method is highly suitable for real-time (or low delay) applications while the benefits from multi-frame motion compensation can be preserved.
