UPDATE: 2016 12 09: Patch 1.05 Fixes HDR bug.

"The Witness HDR implementation is completely amazing on my TV"


UPDATE:

We determined that we do have a bug in the actual HDR rendering code of The Witness. We are going to issue a patch pretty soon, but we don't want to rush it out immediately, because we want to make sure our fix is good, and be careful not to break something else!

Should be fixed soon! Thanks for the awesome communication!

for posterity:

At least on my Sony X800D lol. (and I am not the only one: scroll down for a temp fix, hopefully until we see a patch)

Anyway, Several GAF'ers had discussed issues with this games' HDR implementation, but no-one had posted images, so here goes.

I ran some tests here, examining bit depth, chroma subsampling and image quality. The findings: the HDR is completely broken, with severe issues with color mapping and color banding.

I took this from my phone, as you will not see a difference using in-game screenshot. Here is looking back down the hallway in the very beginning. Bright magenta 'shadows, I think really the pictures speak for themselves. Notice the walls to the immediate left and right, no banding, no gradient evident.

Auto PS4 settings with HDR on results in 12-bit YUV422. Forcing 10-bit YUV420 did not display a noticeable difference, so I don't take a photo.

Now examine the scene in SDR, where i forced 10-bit YUV420 (there was a slight improvement over 8-bit RGB 4:4:4 in the darkest areas in the gradient). You clearly see no magenta, there is a bit of banding, but noting like the ridiculousness of the HDR enabled image.

So what do you got for me GAF? Can you take an off screen photo with HDR enabled looking down this same hallway that isn't severely busted here?


EDIT: I should mention that bright areas are spectacular looking and the HDR really does add a very much surreal look to other areas, its just the dark areas that are having major issues, from what I have seen so far.

2nd EDIT: sigh mod title edit lol, can't agree with the assessment that this is a 'my tv' issue, I still think it is the game due to the 'fix' implementation...

3rd EDIT: Witness Dev Jonathan Blow communicated that they would look into the issue.

4th EDIT: Wallach was right... this thing is botched and the only fix is to drop down to 1080p, running in full RGB from the PS4 Pro, and then set the display setting to limited! bat shit crazy, but true. It works, I might add that you should also map the color container back to Rec709 for the proper color space. You still get a gorgeous HDR picture, but hopefully even better if a patch comes.

Below is an image of the same hallway (I ran back so maybe not on the same stair) but as you can see, the issues described have been resolved, somewhat replaced by new issues of lower resolution.

Its your TV I read somwhere that ppl got issues with UC4 HDR mode to.

 

[RuhRo]

Same problem on my Samsung. Horrific color banding. Mine also defaults to YUV422 on this game. I find forcing YUV420 marginally improves the banding, but does not fix it.

All other HDR games seem to look great (Uncharted 4/Last of Us/Deus Ex....). Why is The Witness broken?

No matter how similar you think they are, pictures of a display are never a good substitute for direct-feed screenshots. Especially since the PS4 will easily create pixel-perfect PNG shots. If you want people to be able to help you, you should post those instead. Otherwise, they might be trying to fix issues with your phone's CCD, not the game or your TV.

HDR doesn't come across on screenshots which is why he's taking a picture of it.

 

[Audioboxer]

I would check it out for you on my Sony set if I owned the game. Thought it would appear in BF sales.

After the help you gave me in the other topic about the Pro I wish I could do more to test this myself!

Yes, you don't understand. That bright magenta is not supposed to be there. When shooting a screen cap from the PS4, you do not see any magenta, it looks quite a bit like the SDR image in fact, so the only way to actually show something close to what is being shown is to take an off screen image.

What the images should convey is the difference between a magenta and white hallway and one that is dimply dark. That banding is not coming from the phone, it is seen with the eyes, and looks like what has been posted.

This game has been on my short list for too long, and several people had told me that the HDR was broken, although it is quite stunning in well lit areas, you can see there are some serious issues in darker regions...

I was hoping for BF sale as well, but no luck, so $40 it was

Taking a picture is not going to help you see HDR. As he explained, the reason he took the photo is not to show HDR, but to show a problem that isn't there in direct-feed shots.

If the image being generated by the PS4 doesn't show this banding, that suggests the problem may be with how your display is choosing to render what's being sent to it. That could either be because the game is sending wonky data, or because the display is misinterpreting good data it's receiving. Saying flatly "The Witness HDR implementation is completely broken" is thus very misleading. (Not to mention that even you agree the HDR is fine most of the time, which definitely means it's not completely broken. But I'm sure this was just frustrated hyperbole.)

Interesting feedback, but the PS4 cannot capture metadata in the Jpeg or GIF, so thats why it looks quite similar to the SDR implementation if I had to guess.

I still think it is patently broken in low light conditions, which likely means that the entire mapping is off.

No, its not that simple. Other people with different displays have described similar issues.

I haven't posted it yet, but that bright magenta cast also occurs when I engage the AVR GUI, which with any other game in HDR or SDR, there is no cast at all.

My suspicion is that there is some issue with at the metadata level.

 

[dark10x]

That's disappointing. I've found it to be one of the best HDR implementations on my display. Extremely vibrant with clean color gradients.

The dark areas have none of those issues either. It's frustrating to see how inconsistent HDR seems to be.

 

[Masterbrew]

I read about the banding before starting The Witness, so I kept my eyes open for it, but did not see any.

On a C6 OLED, in HDR standard, deep color input, with a normal PS4 outputting auto.

 

[michaelius]

Check the cables - my friend had same red haze everywhere in Uncharted 4 and it turned out it was cable incapable of sending full signal.

 

[McSpidey]

My guess is magenta is such a specific colour to map a near black value to that it has to be the TV mis-interpreting the signal somehow. Like how a video codec can turn pixels purple when it has a decoding issue. That your AVR overlay is also getting a magenta cast says it's definitely in the TV decoder path, which I agree could be influenced by HDR metadata..but on the TV interoperation side, but also confirms it isn't coming from the game's frame buffer. That said, I can see some magenta colour influence in your SDR photo too, which suggests that colour is present in both so could be coming from the game.

Ok, I will do a cable swap, I have a couple of 2.0's lying around. I am hesitant only due to the fact, I haven't had this issue with any other HDR enabled game.

So it's a problem with your TV, not The Witness.

I think there is an issue with the metadata at this point, not sure it's the TV's fault yet. What you quoted doesn't lead to the TV being the culprit, but it is becoming clear that some displays are not having the same issue.

That's not necessarily true though. The image that the PS4 is sending out is always going to be different to the screenshots from the share feature, because a JPG/PNG can't encode 10/12bit P3 colours. So the screenshots have to be pre tone mapped to SDR and won't show any potential erroneous HDR data.

 

[Waikis]

Have you tried adjusting gamma around 30 IRE? Looks like a blown up gamma error with the title.

Actually, PNG can support 16-bit color channels. However, you're probably right that PS4 only uses 8-bit.

The set is calibrated in SDR with a i1Display Pro to 10-point grayscale. I will re-check with some sweeps maybe tomorrow.

This brings up a good point that the EOTF may not be mapped in a way that the Sony is expecting, but is somehow compatable withe the LG OLEDs, which as I understand, have some issues with inFamous HDR.

 

[Karak]

Tested this just now with the 3 test sets I have the 4th and 5th aren't here until Wed.
0 of them have that issue. Sadly we returned that particular Sony to the company. So I didn't get to test on that one.

Can you point me to instructions on how you did that. I have one and want to do my TV but have no idea where to begin. It's so easy on the pc lol.

Of course. I use the AVS709 disc, and then HCFR to measure. If you have the i1DP, HCFR should pick it up easily, no adjustments necessary.

Burn the disc AVCHD to a DVD. Then pop that in the Pro and it will output in Rec709 at 1080p res, just like a Blu-ray.

Start with measure, grey scale and colors, save the file, and then begin on your adjustments.

Hopefully my plasma lasts me long enough for manufacturers and developers to figure out this HDR thing.

Actually just realised that X800D doesn't have 10-point gamma?
When you said you did the greyscale sweep, did you check for gamma level as well or only RGB white balance? are you targetting 2.2 gamma?

Yes, 2.2 target 6500K color temp.

Right no way to adjust the gamma on a scale, just presets...

And no CMS... this TV is now driving me crazy, but it's the best ~40 inch TV, and I do love 4K and the HDR has been perfect aside from this game.

From that thread:

I just got off this game to say the same thing. The HDR in this game is glorious. So much so that when I turn it off to compare it's like they intentionally fucked up the normal game so that HDR looked that much better. The difference is fuckin' huge.

The 30 FPS 4K mode doesn't seem so hot, but fortunately the 1440p upscaled 60 FPS mode looks great.

Edit - I will say - and maybe this is just the limits of my X800D - that the really dark area at the start in the tunnel didn't look so hot with HDR on. Like it wasn't using 10-bit color or something.

Same TV as OP, as well.

From that thread:

Yeah we discussed it more in another thread, though not to much progress.

Like I said there though, the most bizarre thing to me is that the only way to get it to look right with HDR on is to force the Pro to 1080p, mismatch the Pro to RGB range Full leaving the TV at Limited (this seems to actually matter on the Pro below 4K) then enable HDR in-game.

Glad you showed.

Will try this ASAP. I did actually try dropping resolution to 1080p RGB at 12-bits with HDR, but admittedly did not attempt to mismatch the video levels on purpose.

Wow good article.
Didn't know there are so many problems with OLEDs.

OLED as a technology suffers from gradual pixel decay issues. These latest LG OLEDs resort to a 10-20 minute "Cleaning" attempted auto-re-calibration cycle when the TV is in powered standby after around 4 hours of viewing time. Even this cannot solve the problem. The accuracy of the calibration is poor, which is why OLEDs have such a problem reproducing anything interesting in the darks.

Yuck

Hey y'all,

It goes without saying that we want HDR to work properly for everyone. We will investigate and determine whether this is something we can fix through a patch.

We don't know yet whether this issue happens only on certain TVs, or certain firmware versions for those TVs, or certain combinations of PS4 and TV settings. We'll see what we can figure out. Since HDR is new, it is not too surprising that there are wrinkles, but we will do our best to iron them out.

I do recommend updating your TV's firmware, since we have found that TV makers are still dealing with HDR and problems tend to improve over time. In the meantime we will try getting one of the reported TVs and see if we can reproduce the problem.

If it helps anyone troubleshoot the issue, I am on the latest patch (Nov 16) 6.0.1 Model # XBR-43X800D

Thanks for all your communications both pre and post patch!

 

[Lord Error]

AFAIK, Jonathan's team has B6 LG OLED as their testing HDR TV, so no surprise it will look right on that and similar OLED TV models. Considering how many differences there seem to be in HDR implementations between different TV manufacturers, I'm not surprised that some games don't look quite right on all of them.

 

[fudgey_lumpkins]

OP I think you have to manually turn on "HDR Video" in the TV's action menu under picture adjustments > picture mode. You also have to manually turn it back to "Game" when you're done, at least that's how I have to do it on my X850D

Hopefully, Sony will put out a firmware update to fix it.

Yeah HDR is turning out to be an insanely mixed bag across TVs. Not to mention other issues with full RGB/limited on some Samsung TVs where it doesn't switch right. Then there is others like me who didn't know about limited RGB with HDR and was forcing full, mucking up black levels. Fun and games with calibration and TVs!

Holy shit this is exactly correct! The banding disappears immediately. Excellent work and thank you.

So the issue is with an incorrect limited or full flag in both the 1080p and 4K implementation. HDR should always be in limited, hence YUV anything..

So to avoid this mess, drop down to 1080p, output all auto from the Pro video output settings, at which point the Pro will be outputting 12-bit RGB full 4:4:4, then in display settings on the TV, switch to limited, as the auto will be detecting full from the PS4.

I can add another fix: when HDR is enabled, the TV expects a BT.2020 color container... well it appears that this HDR master was never mapped into BT.2020, which leads to pink highlights ind off colors in general. Change the colorspace back to Rec709, and you will see the average picture level and color space 'snap' back to where they should be (easy to know from SDR implementation).

Don't worry, the HDR is still very apparent as soon as you walk out of the tunnel and into the fort grounds, and its very pretty, the colors aren't quite as surreal, but it looks as it should, APL SDR = APL HDR...

The X800D doesn't require this! I can leave in game mode and it works well, perfectly outside of this game.

I will update with a comparison pic.

Hopefully, we can still get a fix for this to retain the 1440p 60 fps mode!

This is disappointing as The Witness is by far the best looking HDR game. The difference between HDR and SDR is massive.

And I have the 850c which is a year older than yours. I wonder how big the difference between 800 and 850 is.
Also have you tried changing the tv to BT.2020?

You are correct to think it should be BT.2020, but it is incorrectly mapped inside that container. Switch back to Rec709 for accurate colors.

No worries, I'm glad someone was able to reproduce exactly what I was seeing.

It makes me wonder if the problem is specifically with The Witness or a more general issue with the Pro. I don't have much in the way of HDR content to test against still; the only other game I have tested with is Ratchet & Clank, which I thought looked fantastic but I did notice a tiny bit of oddness with the title screen in 4K, but I don't recall seeing anything quite like this in-game (and there is a relatively dark night scene pretty early on where I feel like it would have been pronounced). The way it looks correct when the RGB range is mismatched at 1080p really threw me for a loop and I still don't quite understand what is happening there.

I don't have much in the way of HDR content to test against still; the only other game I have tested with is Ratchet & Clank, which I thought looked fantastic but I did notice a tiny bit of oddness with the title screen in 4K, but I don't recall seeing anything quite like this in-game (and there is a relatively dark night scene pretty early on where I feel like it would have been pronounced). The way it looks correct when the RGB range is mismatched at 1080p really threw me for a loop and I still don't quite understand what is happening there.

I have messed around in UC4, and the last of us remastered, as well as 20 hours or so in both bright and dark environments of inFamous, seeing nothing like this at all.

At this point, I have to believe it is an issue with the game HDR implementation. Nothing else that I can think of would explain the video level mismatch and incorrect SDR to HDR color map.

I understand the need to have the game calibrated and working correctly but god damn does it look incredible everywhere else aside from a few narrow tunnels.

The banding in a few areas doesn't bother me at all in the grand scheme of things

Oh, I said the same thing; in the above ground areas the game looks absolutely gorgeous with HDR enabled. The area near the start by the shore where it breaks out into bright orange sandstone with cherry trees in the distance just looks amazing.
