Abstract
Disclosed herein is a method for encoding a video signal, the video signal having at least one frame with a plurality of blocks having pixels. The method includes identifying a prediction mode for a block in the at least one frame, determining a residual for the block using the prediction mode, the residual having an original resolution, determining a variance based on the residual, and if the variance is greater than a predetermined value, reducing the original resolution of the residual to a lower resolution using a processor.
