Dolby Vision now possible through MP4 Mux.

Hi everyone. I recently bought a new PC with Windows 11. To my surprise I found that drag and drop on the command prompt doesn't work and as a result I can't use the script at all. Has anyone encountered this problem and solved it?

Resolved! I don't know why but the user account settings were changed to the lowest point.

mmm Same issues since the latest Win11 update...
Changing the account settings did not work for me.

EDIT: had to reboot.

I'm happy to have helped you!

Quick question, when using dovi_tool mode 3 to extract the RPU from a P5 file, is any from the RPU data lost? I'm asking because the other day, I read someone claiming both chroma and luma data being lost when using mode 3; apparently, only dynamic metadata is being carried over from the P5 files to the P8.1 files.

Is this true? Just curious.

Yes, the mapping metadata contained in profile 5 is not usable in profile 8.1.
It wouldn't make sense to keep it.

Very interesting. I never knew extracting the RPU and injecting it in to a remux was a lossy progress. I thought it truly was the best of both worlds. It seems P5 DV is still absolute best, as it's in the IPTPQc2 colour space and includes both chroma and luma mapping; it's just lacking the bit rate of a Blu-ray.

Which begs the next question; seeing as the IPTPQc2 has been reverse engineered by gifted folk, as it can be decoded by MPV to be properlt played back, is it possible to convert the Blu-ray high bit-rate stream to the IPTPQc2 colour space and inject the lossless RPU to truly get best of both worlds?

Why do you believe the metadata is any better for quality? It's literally only required to decode the colours into regular PQ/BT.2020.
It doesn't improve the quality at all on playback. The process is only lossy in that it loses the original metadata, the quality is unaffected.

And any reencoding of a Blu-ray into IPT would be worse as transcoding is lossy.

Good afternoon, tell me what sequence of script points you need to use to analyze the finished mkv file, you need to get a screenshot similar to what is created automatically when converting HDR10+ to DV, is it possible? I can't find a similar scenario, thank you

To plot DV (graph screenshot), the workflow is 6-2-4.
For just a quick info summary about the RPU metadata in any file: 2-3
to check the metadata of any frame, input an RPU in: 2-3 or 2-2

looks like your file doesn't have DV or you're using an old dovi_tool(not scripts) version.

Is this the latest version?
https://github.com/quietvoid/dovi_tool/ ... /tag/2.0.3

[RESET_9999]

yes but if your tool pack had the old dovi_tool, it means many other tools are missing or outdated... the latest version of the scripts will not work properly.

Yes, it already works, I replaced dovi-tools in the tool package, tell me, and a more recent version of the package can be obtained by a link in private messages, since I realized that you no longer publish to the public
