Enable QP reduction for smooth blocks according to a QP reduction model:
$Clip3(SmoothQPReductionLimit, 0, SmoothQPReductionModelScale*QP+SmoothQPReductionModelOffset)$.
The QP reduction model is used when SAD is less than SmoothQPReductionThreshold * number of samples in block. Separate parameters for intra and inter pictures.
The QP reduction model is used when SAD is less than SmoothQPReductionThreshold * number of samples in block.
Where SAD is defined as the sum of absolute differences between original luma samples and luma samples predicted by a 2nd order polynomial model.
The model parameters are determined by a least square fit to original luma samples on a granularity of 64x64 samples.
MaxCuDQPSubdiv is preferably set to 1 or 2 to achieve best subjective performance.
