there is a New Version of dvdfab, in this you can use copy, but you can change to profile DV single pass.
This file is a copy of the orginal and dvdfab muxes DV 2pas to DV 1pas. This will play inn mrmc Perfect..
It onle uses 12-20 min to make the file
12-20 mins smells like a pure remux/merge which is what a copy would be.

Are subtitles in the right place ?

Profile 7 must use BT.2020 color primaries/matrix and profile 5 must use ITP color primaries/matrix and full range. I'm not sure how you can achieve this by a copy process.

This makes no sense. Profile 5 is not HDR10 compatible. It would have made sense if it was profile 8.

amazing, this appears to be a lossless single layer dolby vision file 8-) can you use pleease try mkvtoolnix to mux its video track and the hd-audio track (from source) into an mkv file? apparently this will play in dolby vision! it will be as if you're watching/hearing the actual disc, but in MrMC :shock: Matroska container actually can do dolby vision, it's just been only limited to a single video track this whole time, which is what we now have. even some LG DV demos are mkv.

This makes no sense. Profile 5 is not HDR10 compatible. It would have made sense if it was profile 8.
I thought Profile 5 can do itu-r bt.2020 hdr10?

Profile 5 has only base layer and it is supposed to be ITP/Dolby Vision. No HDR10 cross-compatibility for profile 5. The now deprecated profile 4 did have cross-compatibility.

I haven't done any testing on this, but to me this looks like DVDFab is taking the BL track and writing Dolby Vision VUI parameters. It's not doing anything with the EL track.

@Morten1969: can you check what happens when you remove the Dolby Vision EL track from the folder. Does DVDFab report it as a Dolby Vision title? If it still does, can you make a single stream from it?

how can you just remove the dv el track from the folder? it's muxed into the movie's main m2ts file that dvdfab uses. I'm pretty sure it's taking the second track of the m2ts (the 1080p el) and writing it onto the hdr10 baselayer with rpu parameters
