    Uses past motion information instead of future data from the lookahead.
    Not as accurate, but better than nothing in zero-latency compression when a lookahead isn't available.
    Currently resets on keyframes, so only available if intra-refresh is set, to avoid pops on non-scenecut keyframes.
    Not on by default with any preset/tune combination; must be enabled explicitly if --tune zerolatency is used.
    Also slightly modify encoding presets: disable rc-lookahead in the fastest presets.
    Enable MB-tree in "veryfast", albeit with a very short lookahead.
