Dolby Vision now possible through MP4 Mux.

Nice work! This definitely lends more credence to the Nvidia folks' explanation that the BT2020 tag is not solely responsible for the issues and why it's been so hard to narrow down the cause. Hopefully the HD Fury will at least give them a clue of what's going on. Also exciting that you're not seeing any noticeable difference for playback of the FEL tracks! The mystery deepens

Something else I'm also wondering is if forcing LLDV will solve the red push issue completely, or will it still lead to the red tint that @RESET9999 mentioned seeing in the Doctor Sleep scene even after the workaround. Just another wrinkle to the equation.

I agree that far more testing is needed now that we have some initial toys to play with. I didn't get a chance to look at 2001 yet but it's on my list. But so far I'm liking what I see a lot. If we can get this to be consistent across the board and look as good as a stand alone player we're all in heaven. I still would like to know why the mel track wasn't picked up by makemkv. Seems like a possible bug.

Haven't check mkv yet, but with old p4 ts I can clearly see red tint in "horses", "deer" and "stopwatch" scenes.

Ah that's the first time I've heard of the issue persisting into LLDV mode. Can you tell if you see the red push in the Doctor Sleep scene here: https://mega.nz/file/YSxhkSLK#fkfy54tYV ... xIOBZLyGR4. It may be hard to tell if you have nothing to compare it to since there is naturally some blushing in the little girl's face, but the Shield just exaggerates it.

Also if you have time, can you look at this scene from Saving Private Ryan and see if you notice the flickering that's happening throughout: https://mega.nz/file/8XZljQgZ#P2xzsRWST ... 5fCW9zZa_8 ?

Red push is present
SPR flickers

The MEL track as suspected doesn't trigger DV at all and plays in HDR.

Can confirm. MEL DV (20001.ts) -> 1.15.2 mkv plays in HDR
Still plays in DV with old p4 *ts conversion

Oh I had no idea the x700 supported single track dual layer files.

The saving private ryan flickering issue is also another big concern to me. too bad it's FEL, I can't test the single layer el+rpu on the x700. But I don't recall that I noticed flickering when I watched the dual layer TS.

I have it in dual layer TS on my x700 and there is no flickering.

[RESET_9999]

So, I did more comparison with my x700 and I just can't get a perfect match with any of the single-layer BL+EL+RPU( FEL or MEL). I'm starting to think that the Shield just can't play them properly because I can get a perfect match with the genuine profile 5 full range files from streaming services but never with the uhd-bd rip. It actually makes sense, maybe the shield was never meant to play dual layer rip.

Using a real profile 5(BL+RPU) test pattern, the Vertex completely fixes the red push issue and the colors match the x700 perfectly.

Could definitely be the case that the Shield just wasn’t meant to play back these kind of files. There is confirmed support for profile 4 MEL, though, so I’m wondering what kind of media they had in mind for the implementation. The only official profile 4 video I can think of is the lg demo from here: https://4kmedia.org/lg-dolby-vision-uhd-4k-demo/. I haven’t looked at this video closely or compared the playback off anything else to see if there’re any evidence of the red push here.

[SamuriHL]

That's really bizarre. That's completely different than the results I saw. I'm not able to take screen shots to show it, but, the picture was identical on the SM benchmark demo between my UB820 and the Shield. And I was not using the Integral 2 to correct anything at that time. And yes, I do get the red push problem in other videos. That Doctor Sleep sample that shawnc22 posted, as an example, I compared with my LG internal player vs the Shield and definitely saw the problem. So I have no idea what the pattern is here.

The difference can be hard to see but if you compare a scene with a lot of red colors, it's more obvious.

I've conduct the same comparison with your pattern DV file.
I compared the mp4 played with my Shield RGB bt2020 and with in-app Philips
Shield Normal VS Philips TV https://screenshotcomparison.com/comparison/4946

And my results seems slightly differents
Cyan is brighter with my shield but i'm not sure about a red push
it's very strange

interesting..... yours appear undersaturated compared to the philips and yes indeed, very different than my comparisons but I noticed your taking pictures in a bright room. My pictures were taken in a complete dark room ( black velvet everywhere) without any light. Perhaps thats the difference ? I dont know but I'm clearly getting the same color difference no matter how many comparisons i do.
Also, I assume your camera settings are locked?

EDIT:, you sure the signal is RGB ? I don't know what DV type the Philips tv supports, maybe LLDV ? that would explain why the red color seems ok.
