A video filter (10) for converting color video data (12, 14) stored in a format suitable for use in an 8-bit or 16-bit desktop environment to a 24-bit format suitable for conversion to RGB video data (30) for the display of full color, live motion video. At very high pixel rates, the filter (10) includes one or more buffers (12, 14) for storing sets of video data in UYVY format, averaging circuits (16, 18, 20) for generating average Y, U, and V values based on successive sets of video data in the UYVY format, and one or more multiplexers (22, 24, 26) for conversion to RGB data. The filter (10) further includes means for selectively bypassing the averaging function when there is no successive set of UYVY data, and means for selecting between an 8-bit mode of operation and a 16-bit mode of operation. The filter (10) may be bypassed if no conversion is necessary.
