In this paper we present a statistical analysis of motion prediction with drift in video coding. The drift effect occurs when the video decoder does not have access to the same reference information used in the encoder in a hybrid video codec using motion prediction. Although the drift effect has been known to the video research community for a long time, there has not been a systematic theoretical treatment of this mechanism. Generally the performance of motion prediction with drift is evaluated experimentally. In this paper we derive a closed-form expression for the drift error. Based on this result, we derive an efficient rate distortion optimization given the statistical knowledge of the channel.
