    Do sub-pixel motion search in up-sampled reference frames · e02752b0

    Up-sampled the reference frames to 8 times in each dimension using the
    8-tap interpolation filter. In sub-pixel motion search, use the up-sampled
    reference frames to find the best matching blocks to increase the motion
    search precision. This is enabled as a speed feature for speed 0 and
    speed 1, and this is encoder-only improvement.
