Abstract
Encoding a video signal having a plurality of frames is described. Test frames in the sequence of test frames have an original resolution. A variance for each test frame in the sequence is calculated, as is a first peak signal-to-noise ratio (PSNR) for each test frame using the original resolution. A threshold is determined using the variances and first PSNRs. The threshold is provided to an encoder to select a frame resolution for a first frame of the plurality of frames, the frame resolution being one of the original resolution or a resolution different from the original resolution.
