If you're encoding content with #AV1 in #Handbrake and haven't been using enable-variance-boost=1 , you need to start. All the tinkering I've done with varying CRF values, adding or removing film grain, etc. to try and fix low-contrast areas when transcoding my Blurays has been negated by this option, even in content with lots of film grain and dark scenes.
Basically it's:
- CRF 20
- Preset 3
- enable-variance-boost=1
I've shared my Handbrake preset here:
