Where do I find the Constant rate factor setting In Topaz video enhance?

[Chamberhouse]

For those who really want CRF or lossless encoding “directly” from TVAI, one solution is to use the CLI with modifications to pipe the “raw” output to a different ffmpeg (not from Topaz) which was built with libx264 or libx265. I’ve tried this as a test and can confirm it works successfully. Here is a link to my response in that regard to lossless (but the example applies to CRF or QP in general):

Using x264 crf mode in 3.x versions?

Here’s a present for you, if you really want libx264 lossless and willing to do some faffing around: You would need to change my example -vb 8000k to something like -preset ultrafast -qp 0 Andy

Thanks.
