[Help] How to convert Dolby Vision Profile 8 to 7 to make it UHD BD compliant?
#1
I have a mkv with Dolby Vision Profile 8 I want to burn onto a UHD Blu Ray to replace to HDR only video stream, and Dolby Vision on UHD discs are usually Profile 7, how do I do so since I'm new to making custom Blu ray folders and discs?

There's a command line program called dovi_tool, I've used it a couple times to remove the DV layer from some files that wouldn't play right on my Samsung 4K monitor, but I believe it can change profiles.

What command should I use to convert profile 8-7? I can't find a command online.

Hi.
It's possible using official Dolby tools.
I've attempted this and you need a big big ssd.
It's not even officially documented.
You can't do this with dovi_tools.
Some people advise to mux dv P8 into a dummy 1080p video
as a FEL layer but it does not work like that.
It won't be an improvement, just a bigger file size.
Maybe do I tools will support this eventually.
Im also looking for this in order to use streaming DV in a Custom UHD structure.
Regards
