I think the L5 metadata does vary when necessary, so it shouldn't be 276/277 everywhere..
If it is, then I guess it just doesn't matter for UHD BD.
yep, it does vary because with the hdr10plus to DV remux of WW84, the imax scenes play incorrectly in 276/277 on my C8 internal player.
the original dual-layer file (the p8 too) play correctly in 66/66

it plays perfectly in 66/66 and switches to 276/277 without issues on my bluray player x700. surely because l5 metadata are useless to bluray players. shield is fine too

Right, normally you would have to find the scenes where the aspect ratio changes and edit them in the other RPU.
Alternatively I'm pretty sure leaving the L5 to 0 also works.

But you don't have to do any of this since the content is already Dolby VIsion :!:

I don't have enough samples to confirm if L3 is correct nor to add anything more (other than possibly automatically calculated L4).

Works like a charm,
Once 4.0xml is parsed
I have 2 choices encode from the Master with Rpu/ encode raw with Rpu both work .

Re: Dolby Vision now possible through MP4 Mux.

Post by higher »

Sorry for asking this but is there a way to mux or convert Dolby Vision mkv's to mp4? Unfortunately LG OLED TV's built-in players are not recognizing DV in the mkv container and I don't have an X700 or Shield 2019. Excuse me if it had been asked earlier.

Keep up the great work!

Good to know.
It's a little weird to see L2 stronger adjustments for 1000 nits but less for 600. Only you would know if it's correct though.
The trim_slope (Gain) is still possibly wrong, since I couldn't match the values all the time with the samples I have.

Quick test sample works
Possibilities are now endless
What’s great about this tool even if u have a Dolbyvision license u are now able to view your work before it goes mainstream in doblyvision with all the trims well, almost all the trims.
No one can view their workflow in dv well only using rgb tunneling but that’s it u have no acess to your doblyvision created content
Hdr10/sdr only for playback now we have it all.

Re: Dolby Vision now possible through MP4 Mux.

Interestingly, the CX internal app sends a bt2020 flag with DV like the shield used to do...

I bet that explains the difference @galarond is seeing with his C1 internal player and the x700.. I assume the C1 flag bt2020 as well. Doing so saturate the color more: https://screenshotcomparison.com/comparison/16962

damn , DV is a mess!!!

hulu recently added dv and hdr10plus support and it looks like they are all in profile 8 DV ... Make sense, no time wasted encoding both HDR10 and DV base layer.
Since it looks like the appleTV is doing fake DV with profile 7/8 , I wonder how it will go lol ...

@quietvoid

the hdr10plus to DV conversion works very well IMO. I watched a 2h Amazon movie in DV and I don't see anything wrong. Brightness change is not visible at all, perfectly smooth transition. I didn't create any l2 metadata, I added l6 metadata and I adjusted the active area, that's it. And just to be sure, I made an off-sync version with the RPU late 120 frames and I could easily spot the brightness adjustments. I still would like to take a look at manix shogun lldv capture though... Still, DV couldn't save the horrible amazon encoding, seriously that shit looks like 720p.

Anyway, another major achievement by you, well done. we can basically do anything now thank's to you :D

Sorry for asking this but is there a way to mux or convert Dolby Vision mkv's to mp4? Unfortunately LG OLED TV's built-in players are not recognizing DV in the mkv container and I don't have an X700 or Shield 2019. Excuse me if it had been asked earlier.

Keep up the great work!
if you don't care about subtitles, the easiest and fastest way is tsMuxer .. wont be an mp4 but should play on your lg tv (assuming you're talking about p5 files)
otherwise, you have to demux and remux with the mp4muxer

That's good, I had no problem on my side either.
There's a difference between the target nits but now that we have production profile 8 files with both, it looks like HDR10+ tools just measure slightly differently.

well, depending on the model of the oled you can play dv mp4 dual or single layer, that will show what you need to do. for example in my LgC1 i can only play 1 layer mp4/m2ts/ts files and trigger dv, i had a lgb6 where i could play dual layer mp4 but only mel movies and fel very very buggy.

so first to know that to see what you need to do to make a watchable file in the internal player of your tv and trigger dv
I have an LG C8 and it plays dual and single layer mp4's flawlessly. I tried remuxing to ts with tsMuxer but it doesn't trigger DoVi so I guess it's P8 which the TV doesn't support.

Thanks for the reply. So shall I demux the video track with tsMuxer then remux it with mp4muxer using profile 5?

the C8 supports all the DV profiles.
The ts file you tried must be dual-layer which the c8 won't trigger DV in this container (or it will even say ''corrupted'').

so you have to demux and remux with the mp4muxer using profile 7

I was trying with a Hulu DoVi mkv file floating on the web which is Profile 8 but remuxing it to ts didn't trigger Dolby Vision, only regular HDR.
