The subject invention has both apparatus and method aspects. A first embodiment of the method aspect is for encoding a video signal having a plurality of frames, each frame having a plurality of blocks. The method includes identifying a first frame from the plurality of frames as an I-frame, the first frame having an original resolution. The method also includes determining a variance for the first frame using a processor. If the variance exceeds an intra threshold: (a) selecting a frame resolution for the first frame that is less than the original resolution, and (b) encoding the first frame using the selected frame resolution is performed. |
