HDR support not working

[Boomslangnz]

Hello, been using this for ages and its great!

however I have tried enabling HDR now and just cannot get it to ever work. It only ever shows black screen (i can hear audio fine)

I saw on documentation it said

Media Foundation can't create a HDR video. Therefore, you have to install Turbo Play and use my own Media Foundation library which can use NVidia Encoder to create true HDR-10 videos. If you install Turbo Play, in the installation directory, there's a file nvh64.dll. Run regsvr32 with it as administrator and my filter will be registered for you to use with the Screen Capture.

Ive tried doing this too and no difference, still just black screen on video. Any ideas how to get this to work correctly?

Thanks

Can Turbo Play itself capture your screen in hdr (sc64.exe)?
