Dolby Vision Profile 7 & 8 support (.ts/.mkv files)

I moved your post to the currently running thread on this and here’s a post from James that may help explain the reasons behind the change. Also he offers a possible solution to for some users.

6 posts were split to a new topic: Using an app other than Infuse

Thank You, the other posts did not address tone mapping. OLEDs will not reproduce 1000 nits and all will tone map, in which case the viewer is at the mercy of the algorithms developed by the engineers at the TV manufacturers. In the past I was partial to Sony (I have the A9) since in very serious level playing field direct comparison shoot outs I would attend at CEDIA, the Sony’s Tone Mapping and other processing really did whoop the earlier LG and Samsung TVs. But in all frankness LG has seriously upped their game in the last few years and if I were given a chance to choose which OLED to choose this year, it would be a toss up. Now onto the DV issue on Infuse/AppleTV, yes the new update IS playing DV files that did not render correctly before at all. As for the loss of the DV flag on some other videos I have not noticed it yet, probably fell back to HDR or HDR+ but the picture performance appears unchanged if so. So I agree that the most likely reason is the earlier iteration was identifying DV flag incorrectly while actually rendering HDR/HDR10.

Hi guys …

I haven’t tried those kind of movies for a while but is it normal that “Dolby Vision UHD RIPS (untouched)” are only played as HDR movies while they perfectly play as DV movies on my UHD standalone player ??

Thanks fore the replies !

Yes, Apple TV doesn’t support UHD Dolby vision.

oh god … how could I miss that point ? ATV4K is LLDV, not DV … and as UHD movies are DV, quite logical that I only get HDR out of my UHD Rips !!

Thanks for the reminder @munpip214 :=)

Huh? Player-led (LLDV) is very much DV (and I believe the Apple TV will do TV-led DV anyway if the TV supports it). It’s the profile that is the issue here and DV movies on disc are profile 7 which is basically only supported by BR players. That is why Infuse/Apple TV h/w only plays back the base (fallback) layer.

I made an account so I can say thank you for this breakdown, and thank you for having the goal of showing the most correct information. I’d much rather be told what I’m actually playing, rather than be told it’s DoVi when it isn’t. Hopefully in the future we can get more support for DoVi profiles from Apple, or even better, Dolby consolidates their absolutely insane system.

It’s too bad it’s not possible to convert from the higher profiles down to 5. It has made me realise that actually most DoVi files available are not, and cannot be compatible with Apple TV.

How did Plex solve this? I can play back DV from my UHD BD rips in DV without an issue in the native Plex app. Infuse falls back to HDR10.

They didn’t. They just tell the TV to go into DV mode. It’s playing back the HDR10 track but forcing the tv into DV mode. It’s the same effect as running the AppleTV in DV mode and turning off match content.

Good to know. That’s a pretty idiotic solution.

Unfortunately they aren’t the only underhanded ones doing stuff like that. Zidoo and Dune actually play back the RPU but ignore the EL and advertise that as full Profile 7 support.

But it made a shiny blog post. :joy:

The final nail in the coffin for me with Plex was the blog post about the integration of streaming services.

More specifically right at the very bottom… so almost as a side note it says…

“Got your own media? Plex can do that too”

What made Plex great is now just an afterthought.

I’m tried with real Profile 8.4 test files, but the Infuse and Apple TV 4K 2021 does not handle the RPU, please check: [DV 8.1, 8.4 RPU Test files]

Do they fall within the specifications stated above? What do you mean does not handle? No video at all, doesn’t set the DV badge, bad color?

8.1 fallback to HDR - it is OK
8.4 switch the display to Dolby Vision, but the Infuse (or ATV) does not process the RPU (dynamic metadata) - it is BAD

@james
Will there be a solution to this, or is it up to Apple, like HDR metadata? Since the Apple TV doesn’t support HLG HDR output, playing DV iPhone footage in HLG mode is not a solution either.

What is the source of these videos? Profile 8 DV support on Apple TV is essentially just for videos shot on iPhone.

Created by the developer of dovi_tool based on iPhone 13 RPU samples, so I’m sure the files are good. I tried it with the internal player of my Philips TV and the picture changes as it should.

You can try playing it through the Computers or TV app to see how it works there.

The Apple TV likely has different limitations than the internal Philips TV player, so that is not really an apples-to-apples comparison.
