Thanks, I'll give it a try. I've been testing all the steps in my workflow, and it seems Topaz has trouble with the default Hybrid ProRes encoding. When I set VUI matrix as "bt709" rather than "auto" in step 1 (deinterlace and encode to ProRes from mpeg2), Topaz handles the file correctly in step 2, and Hybrid works without problems in step 3 (the final re-encode from ProRes to AV1/H265/whatever).
So until Topaz fixes the problem, users should be sure to select "bt709" as the matrix if they first deinterlace their source material in ProRes with Hybrid. I'm kind of surprised I'm the first to encounter this issue, because it seems that deinterlacing source material before feeding it to the AI models is the generally accepted best practice in the Topaz community.
