Quantizers are a constant for the whole frame, except when segment features override them, in which case they are a constant per segment ID. We take advantage of this by pre-calculating those after reading the quantization parameters and segmentation features for a frame. This results in a small 1.5% improvement (~12.9s -> ~12.7s).
