About Strato V, Dolby Vision, and FEL

DieZwei said:
Yeah, but the DV profiles are still standard to my understanding. So if it looks washed out on some display and some not, how can it be a content issue?
I haven´t dealt much with DV in the past since we almost exclusively do projector setup. But whenever I come across a "washed out" image, that has most likely something to do with colorspaces not fitting between content/player/display.
If you output a larger gamut to a display with a smaller gamut setting (e.g. outputting bt.2020 to a bt.709 display), then you get oversaturated colors ("sunburn"). If you do it vice versa - outputting a smaller gamut to a display set to a larger gamut - then you get washed out/faint colors.

Could it be that there´s something wrong with the gamut alignment between Strato V and display?

How many people are downloading the DV version and HDR10 version and comparing the color? I would suspect very few, and unless someone knows what to look for, they may think the DV version looks ok. It could be an issue on every DV capable display with the V and the DV profile. I would bet the K engineers are already on top of this and have a very good idea what is going on.

That´s true.

Yes.
 
Sometimes when I start a movie my Strato V shows white "flashes" in almost a strobe-light effect. If I stop the movie and restart it, this goes away. Any ideas? Could this be a connection issue? HDMI releated? I am using a Sony A9G OLED 77”, Marantz AV7704 Pre-Amp, Marantz MM8077 Amplifier. Thanks.

Unfortunately, dolby vision profiles are provided by Dolby Labs. It will be up to Dolby to address the issues, and they are known to be quite slow to fix issues. This is likely not a K device problem. DV has been a problem on TV's for years, specifically with Sony, and it took Dolby over a year to fix DV on the Sony A95L.

But in my case its a non DV display. There is no "Dolby working with the manufacturer". The problem is with the V and how its converting/or whatever its called a DV title played on a non DV display. Also, its not all DV titles...but enough to make me force HDR10 downloads and not have to worry about it. Again a option to make that default would fix my problems :)

So many what appear to be HDMI related issues being reported...I really hope we are not dealing with a HDMI hardware flaw with whatever HDMI hardware is used in the V.

The A9G uses player led DV, so when the V is set to auto its probably trying to make a handshake through the devices to determine whether to use player led or tv led DV. Try setting the V to default to player led.

Makes sense, will try that, thanks. It's not a huge issue for now, fortunately. Only comes up every once in a while.

These are all the same things I'm seeing. DV on DIsney plus etc. looks fine. DV on the Strato V is much more washed out. I don't bother downloading the DV copy anymore because at best it's going to be the same as HDR10 and much of the time the content I watch only looks worse.

Are you guys seeing issues with DV copy on Strato being output as HDR10?

Just being too bright?

Well just the opposite...colors (especially reds and some greens) comes across as "dimmer".

Top Gun: Maverick....the beach/football scene is overall noticeably dimmer when playing back the DV version on my projector than either the HDR10 version or the disc or even from streaming.

All I can guess is that something about the DV version played back on the non DV projector is different enough from the HDR10 versions to effect how the JVC does DTM..but not sure.

Wow what a cluster for DV. I have dozens of DV versions downloaded.

I did that quite a bit while on vacation. Just checked the Force Awakens clip with the red First Order banner and can corroborate your findings in a DV vs DV comparison (Strato V vs Disney+).

I got the latest fw this past Monday too. Though at least so far that has fixed DV interop issues for me *knock on wood*.

But something is definitely off with some DV encodes.
 
Meanwhile Into the Spiderverse looks pretty much the same on Itunes DV vs Strato DV

I know it´s just a photo, but the ATV shots look oversaturated to me, the Strato shots look better IMHO.

On Last Jedi? I also have the original disc print that has DV and the newer disc print on the saga set that us HDR10 only to compare. Some of the shots are going to be fudged by the iPhones post processing.

The reds in Last Jedi’s throne room and the salt in Crait make heavy use of WCG. Keep in mind that red is the color that sticks out more from going to Rec 709 to P3/2020. 709 red was not great. And that’s kind of what it looks like on the Strato, like it’s limited to Rec 709 red.

Oh yeah same thing in Last Jedi in the throne room:

Apple TV DV on Disney+ vs Strato V DV

@DieZwei Here is the 4k disc DV on a UB820 and the HDR10 version on the Strato V.

As you can see: Apple DV on D+, disc DV and Strato V HDR10 all are basically identical flipping through them (any minor difference in the shots coming down to lighting conditions and camera as I took the first pics last night and these pics are with black out curtains but variable levels of light leaking through).

The one that is different from the rest in the Strato DV version with desaturated colors.

This is pretty much the difference I have seen when playing back DV titles ona non DV display -vs- the straight HDR10 version. I kept calling it "dimmer" but its actually colors being less saturated.

I couldn’t see any difference on Into The Spiderverse (Sony) or Fury Road (WB). Would be odd if it’s a Disney only thing but Avengers movies have been pointed out as well.

Spiderverse has a diff kind of error in at least one scene though.
