A repeatable failure at the same point of the disc is almost certainly a problem with the disc rather than the player. Have you tried cleaning the disc?

Yeah I've cleaned the disc like 3 times. It looks completely spotless yet still freezes up at a that spot. Guess I'll need to buy another copy. If anybody here has a 4K disc of Dunkirk they want to sell just message me. Can be the disc only I don't care

I'm not entirely sure. I just know that it looked exactly the same as the HDR 10 version of it. I also just tested Jumanji: Welcome to the Jungle out and again it seemed like it was exactly the same. The only thing I would think that there may have been a difference would have been the sunlight reflecting off of the actor's faces. It may have looked brighter on the HDR 10 version than the Dolby Vision version. To me though, it looked more realistic since that's really what happens when you are outside and the sun is hitting you like that. Details though looked exactly the same.

I really think that if you have a high end TV, like the LG C9 and CX that you will find hardly any difference between Dolby Vision and the HDR 10 presentations. But, you have to have the Dynamic Tone Mapping Setting set to "On" to make that happen. Otherwise, the HDR 10 presentation will be dimmer than the Dolby Vision one.

It's a long thread, haha, sorry, I just used "Find" within the page and looked for "60hz" to post my reply, I couldn't remember who mentioned it first.

The weird thing is my old TV was 60hz and looked fine for ten years. Back when I bought it, they specifically told me that it was the one best suited to my needs, because it was incapable of creating motion smoothing, which the 120hz 1080p TV had in 2010, and my 60hz TV always created a pleasing, film-like image, which looked suitably flat.

I only use my TV as a monitor to watch BDs, I don't watch sports or play video games or really watch broadcast TV much, so the only thing it needs to do is show movies properly, which it did.

I'm hoping a 120hz 4K UHDTV will solve this problem, but after I most likely return this TV, I'll wait till things are back to normal before I go into multiple stores and try them. I really want to see a UHD BD player output onto a native 120hz TV for myself in store before committing to buying one again.

At least I now know the likely problem, and I do understand why my first comments caused confusion. What I am seeing is not as severe as "motion smoothing," I was using the wrong term. It's much more like the subtle SOE that comes from PAL-NTSC conversion, when British shows like Dr. Who and Are You Being Served were broadcast on PBS when we were kids. Both issues create an illusion of depth, of slight 3D, so the image no longer looks "flat" as it should. That's what I'm seeing here, and it makes sense that it came from 24fps being inelegantly integrated into 60hz.

Can you or someone tell me if this is one of those Sony light cannon titles? I don't own this title either so what does the Panny info say for this titles Peak and Average Brightness?

The container can be an indicator of the mastering monitor, I think 4,000 nits would indicate a Dolby Pulsar.

I tested this out on a few discs.

Please note, Ray Jackson!

Warners use a 4000-nit mastering container 99% of the time irrespective of what the content actually does, which is what the MaxCLL and MaxFALL figures are there to indicate. As said by chip, mastering metadata of 4000/0.005 means it's most likely been mastered on a Pulsar.

Hopefully they'll have a moment where they show the flickering on GITS or the locking up on Knives Out and Midway. Or it'll just be another puff-piece designed to wow the gullible.

[Waboman]

Yes, please address and fix the issues with this player.

Conversely, some UHD BD movies have a listed MaxCLL figure which is higher than the luminance max value of the mastering display used. Go figure . If the session ever comes to YouTube or Vimeo, this presentation may be of value for those showing interest in the subject –

You by any chance running the Cinema Home setting for Dolby Vision? That's the only way I can think of DTM Off giving you a dimmer picture than Dolby Vision. Otherwise enabling DTM makes your display to follow a different tonemapping curve making it brighter apart from the highlights. Dolby Vision in Cinema setting doesn't make a picture brighter. I can turn DV on and off and still it's the same brightness. I don't use the HDR optimizer as the C9 does a great job at tonemapping regardless but I guess it won't do harm.

That paradox is always fun when people realise that one is higher than the other

Seems like a good opportunity to ask about firmware.

Award winning but yet it freezes on a couple of movies in DV never addresses it and no firmware update for over a year now

Love the player but support is lacking.

[Geoff D]

Yeah, we don't need a PR event to tell us how good it is. We'd much prefer to have it firing on all thrusters.

[Fendergopher]

I'm not sure if a "Business Development Manager" is the right person to ask about firmware.

Used ‘dynamic contrast’ on low for a year and the flicker was insane. The shot in Close Encounters where several trucks pass in front of the camera caused the image to constantly brighten and dim every time there was a glimpse of the sky between two vehicles. The Wakanda battle in Infinity War was butchered in all the moving shots of characters against a bright sky. Even some static shots cause the TV to constantly ‘second guess’ itself. It looks like global dimming.

Like I said upthread, it seems to brighten dark moments and dim bright ones. I haven’t been too pleased with how it affected highlights in dark scenes, they look like they’ve been composited in.

Isn’t the Dolby Vision presentation not going to look exactly like the HDR one anyway, because the DV layer has dynamic metadata? Several titles I have like The Shining and Us are significantly brighter in DV (on ‘Cinema’) than the HDR10, Dynamic Contrast (active HDR) on or off.

Yep! Cinema Home (or Cinema) is the picture mode I use. Actually, it's the picture mode that the calibrator recommended to use. And from what I have gathered, it is the picture mode that is the most accurate picture setting once you get the settings correctly set.

The reason I use the Panasonic Optimizer is that at a certain point, the C9 has problems tone mapping higher nit content. This is why I have the Optimizer set at Super High Luminance (1,500 nits). This would allow the TV to Tone Map up to 1,500 nits and then the Panasonic can take over from there. Mind you, the TV can probably tone map even higher than that properly but 1,500 nits is the highest limit we can set the Optimizer on at this time. And honestly, the picture looks fantastic! I have it turned "On" and I just leave it. No more worrying about changing settings. I just pop in a disc and go!
