Abstract
Disclosed herein are methods and apparatuses for encoding a video signal having a plurality of frames, each frame having a plurality of blocks and an original resolution. The method includes identifying a first frame from the plurality of frames that is predicted using inter prediction, determining a first variance for the first frame using a processor. selecting a first frame resolution from one of: (a) the original resolution or (b) a resolution lower than the original resolution for the first frame based on the first variance, and encoding the first frame using the selected first frame resolution.
