Frame-skipping transcoding with motion change consideration

Transcoding is adopted to deliver video content to a broad range of end users with different preferences and bandwidth constraints. Frame-skipping transcoding is one of the solutions to reduce the temporal resolution of the video sequence and decrease the overall bit rate. Traditionally used control scheme in frame-skipping transcoding is based on buffer constraint or considers the motion activity of each frame. In this paper, we would like to propose a new frame-skipping control scheme that considers the motion change and tries to reduce the jerky effects caused by the undesired frame skipping. Experiments show that proposed frame-skipping control scheme can produce transcoded video look more like the original one and hence remain the visual quality.
