[Feature Request] Encoding with CQ besides CRF

[Pete4K]

Is your feature request related to a problem? Please describe.
The encoding is only possible by using CRF.

Describe the solution you'd like
When you could do an encoding with CQ you could maybe encode it to H265 with 10Bit in lossless quality and smaller filesize immediately without the step to use Handbrake. Anime looks much better in the quark with this encoding.

Describe alternatives you've considered
When this don't work, then maybe it is possible to do something against the color stripes in the dark or you could use some code from Handbrake. I think that is Open-Source, too.

Additional context
You could see the results by using Handbrake with a 4K file from Video2X. You can choose Video Encoder to "H.265 10-bit (NVEnc)" use the CQ "30" and then setup to slowest and start.
