I told you so. You need to compress BEFORE using makemkv to make the DV MKV.

I was referring at the time you said to use clonebd to do the whole process which is extract, compress and create dvmkv.

No i didn't. Read again. I said CloneBD can't create a MKV with DV.

Don't understand...
You can backup to 1) mkv directly or 2) to folders.
Did you backup to folders?
And of course decrypt.
OK I got it.
ImgBurn is a little dated in terms of 4K discs
What are the Image Options for 4K Discs ?
The below is for blu-ray
File System: UDF
UDf Revision: 2.50

4k is UDF 2.6. But there is no drawback for 2.5. DVDFab saves as 2.5 for instance.

I misunderstood when you said
However, the easiest way would be CloneBD. With that you can pick just the main movie with AnyDVD in the background, keep Dolby Vision and compress the output.

Yes. But I stated also not to MKV with DV. Clearly. There you need the postprocessing.

Post2 in THIS THREAD:
Using payware I can recommend CloneBD which will also do the compression for you and outputs the whole as an ISO. Then run that ISO through Makemkv. MKVs are also supported by CloneBD but only w/o DV.

The first question i have if you can play DV from a MKV file?
If yes, I would recommend to do your compression first and then assemble the files again in TSMuxer with ISO as output and only then run Makemkv to produce the MKV file. TSMuxer is freeware. Look at the last steps of this guide which was created for a different issue:

Hello,
So I used the software on that forum. And I extracted out the
So, What I do now is I can encode down the "BL.hevc" using for example ffmpeg. I can then take that output and combine it with the other 4 outputs listed above using txmuxer. And this will preserve the Dolby Vision ?
Thank You

Yes, that should work. Like said in the tutorial you don't use the RPU.bin that is created.

Quick question. Since I already have an mkv created with makemkv containing DV and another with compressed hdr10 video file. Can I use dkvextrator to extract the EL layer from the mkv with dv and extract the BL layer from my compress mkv and then put everything in tsmuxer to after put it in makemkv? I'm just trying to find a way to save all the time that was already used on the mkv I have while I use the new method on the following compression.

Quick question. Do you know how to extract the BL.hevc and EL.hevc using x265, ffmpeg ? I don't want to use the extractor provided on that forum.
Edit: I think I got it
ffmpeg -i my.mkv -c:v copy -vbsf hevc_mp4toannexb -f hevc - | dovi_tool demux -
This outputs a BL.hevc and EL.hevc using dovi_tool

At the bottom of this tutorial is talks about TrueHD
https://codecalamity.com/encoding-uhd-4 ... th-ffmpeg/
"If you also have TrueHD sound tracks, you may need to use eac3to first to break it into the TrueHD and AC3 Core tracks before muxing."
