Dolby Vision now possible through MP4 Mux.

[darrrkmanxxx]

Hey guys, is there a way to be able to tell if DV works properly on my device or not. I've downloaded a bunch of test files and they all trigger dolby vision but I'm not sure how to interpret them, especially the player/tv-led stuff (chroma weight)
Any guidance/help will be appreciated.

as long as you see that the RPU levels are used (brightness changes), you're fine.

thanks, e.g. on Chroma Weight extreme values 0-4095 DV P8 cmv4.0.mp4 I see a lot of chnages, espcially in "Chroma weight 0" - it bascially created dark whole in the beak.
This is desirable, right?
It's on my Philips TV Oled+ internal player.

yes
you should try the cmv2.9 version as well, on both of my 2022 TVs (LG , hisense) , it doesn't work.

Thank you so much, I'll try that.
Another quick question:
In one of your yt videos (6 different things FEL Dolby Vision Profile 7 Can Do (P7 FEL is not just 12bits)) you mention baked FEL.
How is this done, through MakeMKV?

You need an hdmi device that supports FEL decoding like one of these: https://discourse.coreelec.org/t/ce-ng- ... 05x4/50953
Otherwise, re-encoding is required to bake FEL in the BL. (workflow 8-2-1 in dovi_scripts)

got you, I might get my hands on a Dune HD Premier 4K Pro this weekend. According to your docs Dune hase fake-tv led DV.
Is it the case only wehn using andoid or coreelec, too?
How should I verify working tv-led, chroma trims?

[RESET_9999]

You need the CoreELEC builds for TV-LED and FEL support.

what does mean tv-led exactly? what is the benefit?

[RESET_9999]

it means it's the TV that does the tone mapping and metadata processing. It's more accurate.

@RESET_9999 should I generate a new RPU?

[RESET_9999]

No. Some colorists prefer static L1 with dynamic trims.

I see, thanks

I'm trying to generate the hdr10 brightness plot using workflow 6-2 and see these lines. What do they mean?

[RESET_9999]

install python:

Thanks. What about the below warnings? I just used workflow 1 to inject DV web version's RPU to hdr10 bluray version of harry potter sorcerer stone.

[RESET_9999]

you can ignore it.
These warnings are new in the latest metafier.exe version...I'm not sure what they mean but they don't matter because metafier is just an additional metadata check.
