Fox MaxCLL Data

[Kris Deering]

Fox is one of the studios that in their HDR metadata simply shows the MaxDML as 1000 (or 1200 for The Martian) and 0 for MaxCLL. This makes it hard for tone mapping if you have a more advanced display or processor. Fox titles that are HDR in iTunes show MaxCLL levels though, along with the 1000 nit MaxDML. So I've compiled the MaxCLL values for the titles that I actually have HDR versions for in iTunes for those that may want them.

Alien Covenant - 4127
Dawn of the Planet of the Apes - 1031
Deadpool - 9931 (probably a stray pixel)
Independence Day - 2094
Kingsman The Secret Service - 1225
Life of Pi - 2195
Logan - 1443
The Martian Extended Cut - 3708
Peanuts Movie - 5448
Predator - 1819
Prometheus - 1984
Revenant - 885
Rise of the Planet of the Apes - 1618
War for the Planet of the Apes - 2780
Xmen Days of Future Past - 2542

Remember that MaxCLL is only the highest nit level of a single sub pixel in RGB (so it can be R, G OR B) and doesn't mean that the title has a lot of content at that level. It could literally be a single time in the entire film, but changing your tone mapping to take it into account may change/improve the image on a case by case basis. I find this to be the case more often with titles with a LOWER MaxCLL than MaxDML, which appears to be rare with Fox titles so far.

Tangentially, when the extended info on the OPPO is used for a UHD and it shows the MaxCLL (and others) is the player actually confirming that the MaxCLL is a value actually encoded on the disc? Or is it just parroting back what the author publishes the MaxCLL value as?

I don't think the Oppo players give you MaxCLL, only MaxDML. And it is only telling you what is in the metadata on the disc. The only device I know of that can actually sample the video and give you a value that is outside of the metadata in the disc info is the Radiance Pro. But it has to run a debug program to do it, so it sample in real time and then provides the data. So you'd have to let it run for a whole movie to find out the true MaxCLL.

Yep, the OPPO only does max/min mastering metadata. But, interestingly enough, the Panasonic UB9000 apparently lets you see all the metadata: min/max mastering, MaxFALL, MaxCLL, white point, colour primaries, the lot e.g.

[Show spoiler]

(though as Kris says if the disc is not encoded with certain of that data then even this player will not show it up, unlike his processor which can physically analyse the video stream itself).

Thanks for taking the time to put up these numbers, Kris.

you just made me dizzy from reading all that. my brain does not compute, error code 209 can be seen clearly in my eyeballs now.

Kris, how do you access the MaxCLL in iTunes?
