Dolby Vision x265 Encoding, DV Profile Advantages/Caveats?

[quietvoid]

Thank you! This was it. Didn't realize that Powershell could cause problems. I've never had any problem when using ffmpeg in powershell.

The issue lies in piping data to other processes (the "ffmpeg ... - | dovi_tool ... -" part), so if you were simply using FFmpeg on its own, it would work the same.

Apologies for the "thread necro" but it appears this issue (and a followup one trying to pipe native binary output to a file) was fixed in Powershell 7.4.0-preview, so if you're running 7.4.0 release (or newer, current latest is 7.4.4) it should work fine.

I'm also curious if this process has been refined at all, or if better tools / automation exists?

I've got a rash of ISO backups of my physical media and I'm strongly considering remuxing them to MKV, but I don't want to lose DolbyVision (or other HDR10, etc.) in the process.

Has the "State of the art" improved in the last year and change?

The Ugoos AM6B+ running the latest versions of CoreELEC can play DV from a .mkv container in the format MakeMKV rips them from discs.

Hello,
is it a problem if i not just crop but also scale (3840x2160 -> 1920x***) the original MKV while encoding and inject the RPU_81.bin afterwards?

I checked the parameters of the dovi_tool. There is a crop-parameter but not a scale parameter. I'm wondering if the final video will be OK if I downscale it during encoding. Unfortunately, I don't have the hardware to test this at the moment.
