4k bluray remuxes are already compressed, its called x265/hevc.
re-compressing it further via handbrake or other similar tools, will always reduce quality, this applies to recompressing anything already ripped.
so yes, for best quality, use makemkv to rip and don’t recompress any further.
What kind of color issues? Is there a planned fix?
Thanks
To follow up on this I read on the make mkv forums that when converting a dual layer Dolby vision backup using makemkv the file created is a single layer Dolby vision. Is this correct and does this mean there wouldn’t be issues playing it using Plex and Nvidia Shield Pro?
I re-ripped all of my 4K UHD discs that featured Dolby Vision (about 130 titles) when MakeMKV added support for Dolby Vision, and confirmed that every single title was playable with DV in Plex on a Shield Pro 2019.
However, there is still a bug that prevents the DV flag from being properly processed at startup sometimes, requiring me to restart initial playback 2-3 times until the DV flag properly registers.
That’s not quite correct. The language used for DV makes it confusing.
On the UHD BR disc it’s Dual Track, Dual Layer, DV Profile 7. The first track & first layer is a standard HDR10 stream. The DV Enhancement Layer information is stored in a separate video track. It’s done this way for backwards compatibility with disc players that don’t understand the Dolby Vision information - they aren’t aware of the second track and ignore it.
MakeMKV is extracting the information from both Tracks (and Layers) and producing Single Track, Dual Layer files. The information from both Tracks & Layers is now preserved in one Track.
It’s still fundamentally a DV Profile 7 video, just packaged differently. It still requires a player with support for DV Profile 7. The trouble is that zero players advertise support for DV Profile 7, and none that work 100%.
One thing that can make this more confusing is falsely equating Single Track or Single Layer with DV Profile 5 or 8. This is common in some forums. Changing a DV Profile 7 video to Single Track, like MakeMKV does, doesn’t make it compatible with a Profile 5 player.
I did similar although I do not have 130 titles and none of them played on my Shield Pro (2019 - triangle remote). In fact the only way I have successfully played any DV content was using Sony’s built in Plex client.
To clarify a bit further I’m using a Sony 950H 2020 model and the only DV content that will play is the ones that support MEL. FEL rips do not play at all. Example:
Working / DV:
Oceans 8
Matrix
Hobbit
Not working / No DV:
Jaws
Back to the Future
Beverly Hills Cop
I have to say anything that does work (MEL format) the TV set is utterly amazing. Too bad most of the physical media I own and backup is FEL. Go figure.
Ok, thank you for that. So is there any way to convert to a proper playable dv file using Nvidia Shield and Plex?
I’m a bit confused. What DV profile should I prefer now? I have DV Profile 7 running finde with latest Plex on my Shield TV Pro.
Do you have an example of those issues?
Hi @rv112 - You can download some samples from here to figure out what works and what doesn’t…
https://www.makemkv.com/download/dvtest/
But also you can check my test results earlier in this topic…
Hope this helps you…
If you’ve been happy watching what you have, don’t go pixel peeping for problems. 
lol…
Glad some people can make DV work, but no luck for me. I have an LG CX and got the Shield Pro since people said that’s pretty much the only way to get it to work.
All my DVs are Remux files in mp4. Are there any settings for the Shield Pro and/or Plex client for it that make it more likely to get the DV logo to pop up? I also tried the restarting movie method up to 10 times and it doesn’t work
I do get Atmos to work through my Sonos Arc and no more PGS subtitles forcing a transcode so at least there is that. DV does work on Netflix through the Shield.
I don’t know if it will work if the files are remuxed as MP4s. I just use the raw/untouched MKV file output from MakeMKV and it works.
So no remux files would be able to work at all or a mkv remux would work instead of mp4?
As far as I know, only MKV files work but I could be wrong.
Agree. My MKV’s are working fine. MP4 not.
Did anyone got DV working with Plex after using Handbrake? It seems that the DV information is getting lost.
You should be able to use MKVToolNix to repackage your MP4 files into MKV files.
You can then use MakeMKV to convert them from Dual Track to Single Track.
While there are still some caveats about the Shield, that should be the most compatible format for playback on the Shield.
wouldn’t converting from dual track to single track lose DV quality?
