Dolby Vision now possible through MP4 Mux.

[dysprosium]

I tried the new Ugoos 0.40 fw mod on Minix and from now on just use Plex, DV playback is perfect from STDL MEL/FEL ts, mp4 and mkv too.

Can you give this sample from saving private ryan a try and see if you notice any flickering throughout?

ragico has tested Saving Private Ryan already on the Ugoos AM6 Plus (fw 0.4); I assume the result is the same on the Minix Neo U22-XJ on the same firmware.

It isn’t LLDV nor Dolby Vision that suck. It is the Oppo. It has a chroma bug that most likely is related to the same well known one that reduces BT2020 colors to Rec709 when tone mapping HDR to SDR, which in my humble opinion is absolutely ludicrous.

Both Vincent and Stacey are wrong. Their testing is flawed and they’re passing this misinformation across the web. They didn’t bother to to test with a different UHD Bluray player. I did with comparisons between the Oppo 203, Panasonic UB820, Sony X700 and Sony X800M2, in which the X800M2 performed best in the end and had no such color issues.

I reported this a long time ago. I am the one to discover the LLDV/Dolby Vision trick to play DV on HDR10 only devices. I’ve been extensively testing and experimenting for nearly two years on a nightly basis. Early on when I was doing these tests I was wondering why the Oppo looked so pale in comparison. The Sony was clearly the best. The AppleTV also does an amazing job with DolbyVision/LLDV.

Why not join in on the conversion they're currently having over there on the blu-ray forums if you think Stacey's methodologies are off? It's all a little over my head, but it sounds like a worthwhile discussion if you've been testing nightly for the last two years.

I may just do that, but I hesitate to join yet another forum, especially given the state of them in recent years. They’re mimicking real life and social media with lots of strong egos and keyboard warriors. Way too much “if you don’t think what we think, then you’re a heretic and should be mocked, ridiculed and banned” going on for my tastes lately. I find not participating as I did a few years ago due to being banned at AVS for these very reasons, that I’ve been much happier and less stressed. Who wouldn’t want that?

I just sit back and enjoy my creations myself now. It’s not worth sharing with anyone who doesn’t give back the same respect I give in sharing my hard work and effort.

So I don’t know. Maybe. I’ll see if it’s worth my time arguing with arrogant, closed minded narcissists or not and go from there.

I remember when this stuff used to be fun....

So much words being thrown left and right, can't someone just test Sony X800M2, Ugoos and Minix with DV FEL and then post a few pictures to see the differences (if there are any) ?

Wow, that is quite the request that someone buys all 3 machines and a reference grade camera or capture device just to provide a few screen shots.
Is there a particular brand of TV you would like this test performing on?

Most of the thread has derailed into discussions about Chroma tinting, LLDV vs Vanilla DV among other things, but with posts left and right leading to speculations. Maybe it's time to put it to the test to make it clear?
I would be willing to contribute, but I only have a Nvidia Shield Pro and a LG CX if that matters.

Very interesting post, but Stacey Spears doesn't say LLDV is worse than HDR, at least in that post.

You who have the x700 and make good captures and comparisons can prove it, and maybe you are right

Edit: I found a post from a few days ago from Stacey Spears where he says that DV sucks in BD and that HDR is better

Interesting! I guess he came to that conclusion after testing the new DV pattern from his upcoming Spears and Munsil UHD bluray disc.
I don't really know about chroma upsampling nor ringing and I never really compared with LLDV but AFAIK, TV-LED DV on my setup (x700 + C8) looks much better and brighter than static HDR10 (better shadow details and more pop).
I will definitely check out the new DV test pattern when the disc is out.

There is no way that HDR10 would look better than LLDV which is much closer to or = to dv rgb8.
That would not make sense.
LLDV image is always brighter,sharper & cleaner than a hdr10 image.
We can do a bunch of hdr10/LLDV comparisons, to prove that.
98% of LLDV test captures always looks better than the HDR10.

Thanks for the answer, I said that because @RESET_9999 said it.

I know... and that's why I said I never really compared LLDV because I have issues forcing it with my first gen vertex on my TV-LED setup.

Thanks for the answer, I said that because @RESET_9999 said it.

i never said that.. i just posted a link of someone saying that.
And I was replying to someone saying that there was no difference between player-led and tv-led.

But now the fact that Stacey Spear is considering stripping out DV from the dolby bluray is very concerning and why would he need Envy or lumagen to do that, it doesn't really make sense to me.

Well, I'll get my ugoos next week (probably) and I will surely compare it to my x700 and shield and share my impression...
I don't have the expensive Atomos Shogun that @manix has though.

About 3 year’s ago I realized that the Xbox LLDV could be captured so I started looking for ways to get the better picture it is a fact the all streaming services playback both type of file hdr & dv version & the dv
version has always been better quality than hdr10 @ reset999 could attest to that
Same should apply to uhd Blu-ray’s dv version of the move & hdr10 version.
We are looking for the perfect combination device Mel/fel/streaming/uhd/iso.
& of course top notch audio lol

Just for fun I’ll do hdr10 captures off wonder vision as well all 6 devices so we can compare to the LLDV we got from all six devices

If you could do it with a bd it would be awesome, because Stacey Spears says dv sucks in bd, but he didn't say anything about the streaming

And it would also be nice to see the quality of the chromecast

It really depends on TV
By my observations in most cases Bravia XF90's HDR10 brighter than LLDV, not much but noticable

Thing is, the issues Mr. Spears mentioned are important for video purists like himself.
Chroma ringing? Low quility 4:2:2-to-4:4:4 upsamling? Not accurate PQ tracking? Minor artefacts in LLDV mode?
Most people can't see a difference but they can clearly see a difference in HDR on low-nit TV with inadequate tonemapping versus DV on very same TV
DV wins, case closed.
4 years of DV UHD and now people are talking about DV bugs with only two major UHD players manufacturers left on the market.
Still fully support any bug-hunt and pressure on Dolby. They have to fix this mess.
