Dolby Vision now possible through MP4 Mux.
Re: Dolby Vision now possible through MP4 Mux.
This is the only way I can get Dolby Vision to work in my setup.
Sony 950H->Native Plex App->non-HD audio->Dolby Vision works
Nvidia Shield 2019 Pro->Plex App->Any audio HD included->Dolby Vision works
Both Sony and Shield are hard wired with the content coming off a Linux server with NAS storage (ZFS). Sometimes I'll get some stuttering and I'm not sure what is causing this. I think it may be related to audio which is odd since everything passes through the Denon 4700 AVR.
One backup, Ne Zha, displayed the horrible red issue that has been discussed here from time to time with Dolby Vision. That was unwatchable. Other than that when everything aligns the picture is incredible.

Re: Dolby Vision now possible through MP4 Mux.
Does anyone know if the new Reavon player can play Dolby Vision .mkv?
Re: Dolby Vision now possible through MP4 Mux.
The better question is if it plays DTDL FEL. Also, the speed of the network port.whatsmyname wrote: ↑Sat Jul 17, 2021 11:20 pmDoes anyone know if the new Reavon player can play Dolby Vision .mkv?
Re: Dolby Vision now possible through MP4 Mux.
Are you guys aware someone from BHD ( and some other trackers ) came up with a script to use the online WEB-DL DV layer and combine it with a UHD disk HDR10 layer? Like the movies from Disney Plus. It's DV with streaming, but HDR10 with the UHD disks. As I am typing this, I am trying to get my hands on the script. Will share it once I have it.
Re: Dolby Vision now possible through MP4 Mux.
Interesting. Looing forward to this, especially, if can be combined with ripped MKV HDR10 titlesmulucy wrote: ↑Wed Jul 21, 2021 3:10 pmAre you guys aware someone from BHD ( and some other trackers ) came up with a script to use the online WEB-DL DV layer and combine it with a UHD disk HDR10 layer?

Re: Dolby Vision now possible through MP4 Mux.
There is already Marvel Endgame 2019 remux available in P8 and HDR10 compatible. It works with most devices like Fire TV, Shield and etc. The DV RPU was extracted from Disney Plus and it was later combined with the HDR10 later from UHD Disk. I am working on getting the script.

Re: Dolby Vision now possible through MP4 Mux.
FWIW the profile conversion has been available for a couple months.
I just recently added ways to manipulate the metadata enough to be able to get it usable for different video (different length, letterbox bars, etc.)
The profile 5 to 8 is still very much experimental, and I'm not even sure if there's an advantage in using it when real profile 5 video is available.
Profile 5 colorspace is also significantly better for compression, so it might still look better than "hybrid" HDR10 file, picture quality wise.
Everything is based on Dolby's sample streams, which are the same content available in both profiles.
The code basically only leaves trim passes and analysed min/max/avg brightness parts of the metadata untouched (so all the metadata blocks).
The coefficients are changed to match profile 7/8.
So far there has not been any objective comparison between original profile 5 and converted profile 8.
If anyone finds something weird, I'm always open to suggestions on Github.

Re: Dolby Vision now possible through MP4 Mux.
Sounds like a challenge for @RESET_9999 and @Mannix if they're still around! The bitrate upgrade in the hybrid may be worth the trouble if the comparisons look relatively similar in terms of brightness levels
Re: Dolby Vision now possible through MP4 Mux.
So there is this file Marvel Endgame with Dolby Vision from UHD disk. The disk only contains the HDR10 track. My understanding someone at BHD extracted the WEB-Dl with P5 RPU and merged it with the HDR10 track from the UHD disk. The final video is P8 with HDR10 layer. So, this is not a conversion from P5 >> P8, correct? And there is another video with Black Widow with P8 and HDR10 fallback on BHD. Again, someone took the WEB-Dl P5 and converted it to P8. This approach kind of makes sense based on what you are saying above since the method it's still experimental. I am very confused lol.quietvoid wrote: ↑Wed Jul 21, 2021 8:16 pmFWIW the profile conversion has been available for a couple months.

Re: Dolby Vision now possible through MP4 Mux.
Well said, we definitely need @RESET_9999 and @Mannix to make some expert comparisons

I've been quiet but I'm still reading this thread.
![Smile :)](./images/smilies/icon_smile.gif)
I agree with you , the bitrate upgrade totally worth it if the conversion is properly done and from a quick test session, I don't see any difference between the original P5 and the converted P8 file.
I even muxed two different video sources: this is LOKI from Hotstar India 22mb/s profile 5 rpu converted to profile 8 and then injected to the Disney+ 16mb/s HDR10 release(which I added 72 frames to match the DV version frames count).

Re: Dolby Vision now possible through MP4 Mux.
They are both profile 5 to profile 8 conversions, because the metadata source is profile 5.mulucy wrote: ↑Wed Jul 21, 2021 11:21 pmSo there is this file Marvel Endgame with Dolby Vision from UHD disk.

Re: Dolby Vision now possible through MP4 Mux.
Would this be somewhat of an expected result? My thinking is that both the Hotstar and Disney+ releases are probably from the same master, just that one is offered at a higher bitrate. Maybe a better comparison would be taking the profile 5 RPU from one of the Disney+ Marvel or Star Wars films and applying it to the corresponding UHD disk HDR10 layers. This will probably lead to some varied results, though, as I'm guessing whether or not a disc release and its digital counterpart are from the same master will be different from film to film.RESET_9999 wrote: ↑Wed Jul 21, 2021 11:26 pmI've been quiet but I'm still reading this thread.
