I usually use aq-strength 0.8 and I'm thinking should I raise it to 0.9 or even 1.0?

It's been quite a long time since I did any HDR encodes, but I would start with aq-mode 1 with the default strength 1.0. I use qcomp 0.7 and HDR requires a much lower CRF. My base for SDR HD is CRF 18 so I would use CRF 13 for HDR.
The encoder has probably gone through many changes so I would need to test things before doing any HDR encodes. But those would be a good starting point.
