How does the CRF mode work for VTB? I thought VTB only supports CQ.

Also how do I know what "high quality, medium file size" maps to in terms of actual advanced settings?

I was able to figure out the second question from the logs. It seems from the simple settings that "high quality" uses "CRF" of 0.5, and "indistinguishable quality" uses a "CRF" of 0.7.

That only makes sense if "CRF" is actually CQ, otherwise the number should be smaller for indistinguishable quality. Is it mislabelled?
