Hi all,

While testing out auto-mode-switching in tvOS 11.2 in Infuse and MrMC, I found a possible issue with HDR content. I found that Infuse switched my TV to HDR, but it output an SDR image. In comparison, MrMC also switched the TV to HDR, but showed HDR output.

I tested the Life of Pi sample:

http://hdrsamples.com/life-of-pi-4k-uhd-hdr-sa...

And the Digital Foundry Gran Turismo Sport sample:

https://www.digitalfoundry.net/2017-10-17-free...

Even with the Apple TV forced to 4k HDR, the Infuse HDR videos were washed out when compared to MrMC. They looked like the typical HDR -> SDR conversion.

Is this a bug or am I doing something wrong?

I had the same problem. Infuse plays HDR video, which is much darker than a native player.
The video highlights are not bright enough……

Would you be able to snap a pic of how these videos are appearing on your TV?

With the TV set to HDR, Infuse will display HDR videos with full dynamic range. On SDR TVs, Infuse will smartly convert HDR to SDR and display the videos with a more limited range.

Video: 4K HDR10
TV: SONY Andorid HDR TV
Apple TV: tvOS 11.2
infuse pro 5.6.3

In fact TV native players and Apple TV native players have better contrast and dynamic range

Here's mine, although they don't show the issue very well. One odd thing is that when I took screenshots through Xcode, the Infuse pic looked closest to HDR, and the Mrmc one looked washed out ( opposite of what I see on the TV).

Tv is a Sony x900e

Hmm, I wonder if it's related to some Sony-specific color setting/option.

Coincidentally, we have a 900e being delivered tomorrow, and will see if we can replicate this here.

James,

I've a Sony BRAVIA KD-65X8500D 4K HDR (2016 Model), Apple TV 4K (tvOS 11.2) & Infuse Pro 5.6.3.

I tested a few of the 4K demos below from http://4kmedia.org/ and noticed that the colors for the Sony demos don't look like 4K on Infuse.

When I played the same demos on Kodi on the same TV, the colors were bright & vibrant.

The funny thing is that when I played the demos from LG & Samsung, they looks ok on Infuse, bright & vibrant, not sure why.

Since your new Sony TV is arriving soon, maybe you can try out those few demos below.

By the way, my ATV settings are 4K HDR (60Hz), Chroma 4:2:2, both Match Dynamic Range & Match Frame Rate are ON.

Thanks all. Interesting to see these are all Sony models.

There is an Oppo 203 showing up today as well, which we can use to do some comparisons.

Hooray for new toys! Grin

Ho,a James. En un oled de 2016 (55c6) me pasa lo mismo. El HDR se ve mas oscuro que en el reproductor nativo de la tv.

I have the same problem with Infuse on a sony x9000e (asia/pacific version of the x90e) and ATV 4k (11.2)

ATV 4k

Did some testing this morning too see what the playback differences were between Infuse, and my Sony UBP-X800 UHD player. Both the ATV4K and my UHD player go through a Denon x2300w to input3 on a Sony XBR-940E. The short answer is that the image that's being delivered by infuse looks like the BR version instead of the UHD version. Photos taken with a handheld iphone 8 plus.

The first set is from The Shallows:
1536 is the UHD disc in the UHD player
1537 is the BR in the UHD player
1546 is the BR in the BR player
1547 is itunes UHD

The UHD version played by the UHD player shows much more individual highlighting on the waves, the rest of the images are close enough to each other to not have any real significant differences.

The second set is from Guardians of the Galaxy Vol.2, Same playback devices except no itunes version available.

1538 is the UHD disc in the UHD player
1540 is the BR in the UHD player
1543 is the UHD rip in Infuse
1544 is the UHD rip in MrMC

The main differences here are two things, the richness of the amber colors, and the brighter highlights on the cheekbones, the throne, and the headdress in image 1538. As before, the other photos are similar enough that the small differences are negligible.

HDR is certainly being activated on my TV by Infuse and MrMC, however both Infuse and MrMC aren't sending the HDR data to the TV. I'm going to get Kodi installed today to see if there's any difference there.

Did some testing here on our new 900e, and are seeing similar results. It's a little strange as it only seems to affect certain TV models.

We're looking into a fix.

Thanks robnix for testing so detailed.

I had similar experiences with my Sony KD-X75.
Surprisingly not visible on all HDR movies....
Perhaps a real Sony issue.
A fix would be great.

just my 2 cents

Hi, can confirm this issue with my Sony XD8305 (2016 model).
Same happens with auto-switch or HDR forced.

Hmmm...watched spiderman homecoming in 4k hdr tonight on my LG E6 OLED and thought that it all looked a bit muted. Switched over to MrMC when I was finished and it looked much more like I expected it to. Not sure If it’s infuse tonemapping differently or if it’s just a bug.

Hm, my standard setting is 4k SDR for the Apple 4k, so that I can see movies without HDR as normal as they are and if a HDR movies starts the 4k switch to HDR setting.
That's working with Plex and infuse. MrMC don't switch....

As you described your setting it could be that you are watching HDR over the MrMC with a wrong mapping

Making pictures is perhaps a good idea so I took the same as robnix for possible comparison.

Photos are made by iPhone X, TV is Sony KD75X9405C. As said before Plex & Infuse switching automatically to HDR setting, MrMC not.

description/look at the picture names:
- Plex usage is the same as "my computer" from Apple so I used that
- By pausing on Plex the picture gets a little bit darker through the overlay, so I made one without "Pause" too
- MrMC don't switch on my TV so here is one with normal movie setting and one with hard switch by me to HDR setting

Feedback please Smile

To me, your screenshots from Plex without pause and MrMC set to SDR setting look the same.
The Infuse screenshot clearly shows that the HDR data isn't displayed correctly.
The MrMC with HDR setting looks very weird to me :O

On my side:
In Infuse, no HDR whatever the setting (forced SDR or HDR). I don't use Plex so I cannot test that.
In MrMC : I have to manually enable HDR in the TV settings, whatever the setting (forced HDR or SDR in the Apple TV). But when set manually in the TV, HDR works as expected.

Edit: Infuse is clearly forcing HDR to SDR conversion whatever the settings on the TV or Apple TV. It's like it detects that the TV is HDR capable, because it does switch my TV into HDR mode, but the picture itself gets converted to SDR. Forcing the TV into HDR10 mode (instead of auto mode) doesn't change anything.

Just to confirm that I have just checked and MrMC is switching to HDR without any problems for me.

If I play a HDR file, i can see on the info page on my Denon AV, that it switched correctly to BT2020 YCBCR:24p. What i can't see, if the HDR information is transfered too, but the TV said, it is on, so i would say, it is correct.

What is wrong is the Apple TV content switch, because it automatically uses Chroma 4:2:2 instead of 4:2:0, also if I don't do the speed test. The info page shows --- > --- for color depth, where 10 bit would be correct. I have to admit, that i don't see a difference, so i don't care, but this is something, that the Apple TV is doing wrong.

4:2:0 at 4k 24p is not part of the standard HDMI spec unfortunately. So the Apple TV switching to 4:2:2 when frame rate switching is on is expected and correct.

You think, the 24p is "the problem"? Well i am just wondering, why Denon can't show the color depth. I don't have the problem, if i play UHDs (also 24p) from my Samsung player. It shows 10bit in normal mode and 12 bit as enhanced color. Don't know, what Apple is doing here that just --- > --- come up. If i force the Apple TV Desktop to 60hz (no movie play) to HDR Chroma 4:2:0, it shows the correct 10 bit. If i change to Chroma 4:2:2, its ---> --- again.

I will ask Denon, what this means Wink

Quick update.

We're tracking a few potential leads which could help us resolve a few issues with HDR that are present with some video and panel combos.

More news to come soon.

Just to add my part.

Here I have an HDR video that plays:
- perfectly fine on my (terrible) Philips Android TV's media player,
- perfectly fine on the Apple TV 4K using iTunes homesharing and the "Computers" ap" (the player has terrible performance they do not seem to care about, skips frames, but the images and their colors are perfectly good),
- terribly on Infuse (I tried the original 5.6 release as well as the latest 5.6.4 beta : the dark parts of the pictures are overblown. I also tried switching the Apple TV's video settings to SDR or HDR with 4:2:0 but the image was still wrong.

I have uploaded a 1 minute .m4v sample called DHDRXE.m4v.
If you look between 10" and 20", you can see a lot of bad artifacts in the dark areas. At 0'18" for example, the boy's hair is totally wrong with Infuse (and all right with iTunes homesharing on the same Apple TV 4K, or my TV's native player)

Hope this helps finding what's wrong!

Another quick update.

We've done an enormous amount of testing in the past week, and feel we've isolated the few cases where this can happen. This doesn't seem to be totally specific to Infuse, as a few similar reports with Netflix have also been floating around.

Nevertheless this is something we feel we can improve, and a number of fixes and improvements are currently being implemented. We hope to have these available in 5.6.5 (5.6.4 is already pending review at Apple), and more news will be available soon.

Rest assured, we'll ultimately get this resolved so HDR works great no matter what video you are playing or what screen you are viewing it on.

Thanks for your patience and understanding.
