%X In order to improve the speed of H.264 bit rate reduction transcoding,this paper proposed a mixture video transcoding method with limited drifting error. Selected cascaded pixel-domain architecture to transcode intra frame and selec-ted open-loop architecture to transcode inter frame,at the same time, implemented drift error compensation operation for inter frame. Experimental results show that using this video transcoding architecture, the picture quality obtained from the proposed transcoder is close to that of the traditional cascade pixel-domain transcoder,while the transcoding speed is close to the open-loop architecture video transcoder.
