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. Change-Id: Icec87758925d8f7aeb2dca29aac0ff9496237469
