Yep.

Can someone please post timestamp of this pic?

The hevc stream doesnt have a proper PQ flag (--transfer smpte2084). What a mess they did.

As a workaround, rip the disc to MKV and add "transfer=HDR matrix=2020" in the filename. Then the file can be played properly in HDR with MPC/madVR.

So it is HDR, but doesn't have the proper flag?

What does the disc look like when playing the actual disc on an actual player? If people are getting no PQ with this disc despite it being PQ, one would think that this would be pretty obvious then and look like pale crap and not like SDR? Confused.

I don't know how the disc looks because I only watch rip. But the mkv rip looks like undersaturated crap. Just like HDR look when it's not tone mapped.

without --transfer smpte2084 in the hevc encode, there is no HDR triggering, that's for sure and I expect the same with disc playback.

It all sounds like a big amateur mistake by the studios or whoever encoded the disc.

What the hell is this? We're not HDR Technicians! An average Joe Six Pack wouldn't even have a clue what all of those graphs, charts and numbers are supposed to mean.

sure, roughly:

maxcll= 873 which is the brightest pixel of the whole movie
maxfall= 344 which is the brightest average(avg of all pixels) luminance
mastering display luminance = we can't really be sure but according to those measurements, it looks like it could have been graded on a 1000nits monitor but FYI, the itunes stream has an MDL of 4000nits/P3 color, so I dont know, the information is not available and this is not something that can be calculated

the graph shows the peak brightness of each frame/scene peak.

Why is almost every Lionsgate catalogue release such a mess? Six years after Ender's Game and it keeps getting worse. Do they leave the job to the summer interns or what is going on?

[lgans316]

I am watching the iTunes stream and it looks fine to me except for some blocking in certain shots..There is a fine layer of grain in some shots Its got that blown out high contrast bleached look in certain shots but certainly no fake HDR.

Looks like LG made a schoolboy error with the physical release going by the post above.

Great find! Let’s hope they’ll reissue discs to get this corrected.

That would be an epic gamer moment.

Can you elaborate on how simply changing the file name will allow proper playback of the MKV?

I didn't get the "filename" part either, but thought he didn't really mean "filename".


Anyway, what I'd still like to know above all is how the disc plays on an actual player on an actual HDR TV? Do you get HDR, a pale/desaturated image due to the display not applying PQ (i.e.playing in "SDR mode") or something else entirely?

Does anyone actually own and play the freaking disc?

Adding "transfer=HDR matrix=2020" into any video filename just tells madVR:
"hey, regardless of what the video stream says, this video is PQ so play it in HDR PQ".

I always used this trick to trigger HDR with lossless 16bit PQ TIFF screenshots but I guess it could be useful in case of a major mistake like this bluray disc.
Obviously, you need a recent PC that is capable of decoding HEVC and HDR.

I've bought and received it from Bullmoose a couple of days ago, but didn't open it because I was contemplating on returning it due to Lionsgate's A/V issues on the disc. Something is suspicious about this release, it didn't even have a slipcover, and the printing is slightly blurred on the back cover.

I'll totally open mine for science alone by now, but it's not even in Germany yet... The rest was expected with MOD.


But @cheez avenger should be able to tell what it actually looks like/how it plays already. I mean the actual image, not specs.

[ChisumMP]

The original disc shows pale and washed out colors on any HDR-TV, which is much worse than regular sdr. No idea, why the review on this site gave three stars for this faulty disc.
Thanks to TbeRw01 advice I could create a madVR measurement file, which I could use together with dovi-tool to make a dovi-mkv with basic tonemapping. This new file looks like the itunes screenshots from above.
So, to be clear: If you are not familiar with HEVC decoding and transcoding, do not buy this disc, it is worse than the blu ray from 2009.

[trevorlj]

Wow...what a train wreck. I feel like I got burned by a scammer.

[andreasy969]

Going by the review, maybe people should also name the player and display. The review states "does not have HDR10+ or Dolby Vision" and "while I got a "standard" HDR prompt when I booted this disc, the info page actually showed SDR". Which sounds like plays as HDR, but displays SDR meta datum.

I mean seriously, the review has terms like "oversaturated", "in some of the black and white (now at times almost sepia toned)" and "over the top color moments", which all reads (more) colourful to me (and not washed out due to bad meta data).

So maybe some players/displays ignore the missing/faulty flag?

Reviews on the main site have been sketchy for a while now.
Anyways, being a mod release, I'm curious if this is something that they can easily fix or would it require a new expensive master to be created..
