cant get transcoding to work

The output of that command produces a file that is JUST the video and is DV8.1. The next steps in the reddit post I'm assuming you found, are to reintegrate it with the audio and subtitles from the original video.

I have used dovi_tool with mixed results. Granted, I'm trying to use it a bit differently. I'm trying to go the extra step of creating AV1 HDR10 videos.

DV5 is a completely different format from DV7 or 8. I'm sure there is a process, but I'm not aware of it.
