I have not.
I will make sure to try those out next after this encode, which will run for a few days.

I can confirm it does.
Normally I raise the qcomp to something like 0.70-0.75 and raise the CRF by ±0.5 which 'fixes' it to more acceptable levels.

Though... I always wondered if there was another (more efficient) way to control CUTree's strength/agressiveness more directly... (if I understand correctly qcomp controls a lot more than just things that are influenced by cutree). Hence my question here.
