1. In a video encoder, a computer-implemented method for encoding video at any of multiple spatial resolutions, the method comprising:

  • encoding at least one frame in a sequence of plural video frames at a first spatial resolution; and

    encoding at least one other frame in the sequence of plural video frames at a second spatial resolution;

    wherein the second spatial resolution differs from the first spatial resolution, and wherein the encoder chooses the second spatial resolution from a set of plural spatial resolutions to reduce blocking artifacts in the sequence of video frames.
