1. A method for compressing video data in a computer that distributes video processing between preprocessing hardware and a central processing unit of the computer, the method comprising:

  • passing frames of video data to a motion estimation unit of the preprocessing hardware that generates motion information describing inter-frame changes in the video data;

    performing motion-compensated temporal filtering of the frames of video data using the motion information in a video frame processing unit of the preprocessing hardware; and

    passing the temporally filtered video data to the central processing unit, which performs inter-frame and/or intra-frame compression with reference to the motion information.
