HDRtoHDR proRes

[Pitchnems]

Hello,
This issue has been driving me crazy. Whenever I try to encode a DV file to ProRes, I get this error (or one similar). I cannot figure out what I'm doing wrong. Ive tried to reinstall AviSynth+ and delete all my files and redownload them. Any help would be appreciated. I also get errors when trying to manually measure letterbox. I am unsure if this is related.

This is a direct rip off a disc. It is not a custom file.

It means your video and metadata framecount don't match.
Re-inject the RPU, this will fix it.
