    Aggressive VBR method. · ce7b3845

    VBR method that allows a wider Q range for the first normal frame
    in each ARF group and then centers the min - max range for the rest of
    the arf group on the chosen Q value for that first frame.
    
    This allows for quite rapid adjustment of the active Q range even if the
    initial estimate is poor.
    
    In some cases where the ARF frames themselves are tending to
    undershoot but the normal frames are overshooting this can still give
    net undershoot. This can be corrected by allowing a larger Q delta for
    arf frames but is usually is a sign that the allocation to the arfs was to
    high.
