agree Frank, with sticking to auto ... some good posts from manni in response to you  re  manual selections for the  frame adapt HDR I see :) 

 

Any manually selected strength completely ignores the metadata.

Only AUTO looks at the metadata (once, when content starts playing, as the static metadata for HDR10 is the same for the whole content), decides which strength to select (low, medium, high) based on that metadata (selects medium if metadata is absent or invalid), then completely ignores metadata again, exactly as if that strength had been selected manually. The only effect of AUTO is the initial selection of the strength level.

 

Low highlights compression (dimmer picture / lower multiplier, more details in highlights), medium highlight compression (balanced), high highlights compression (brighter picture / higher multiplier, less details in highlights). Low implies more brightness available (small screens), high implies less brightness available (large screens).

Definitely Al I gave a medium a go with Jurassic World Fallen Kingdom the opening underwater scene it wasn’t too bad but when I used Auto it actually was much better selection due to the metadata it chose I’m assuming high cause it looks heaps better. 
 

Yes manni gave us a good reply on understanding the three which is what I wanted. I’m sticking with Auto I’m done.  JVC got a winner here :)

always good to explore the options Frank, and think you have done some good testing so far to back up where settled :)

I'm watching this discussion with much interest. I try to leave on Auto which usually works well, but sometimes I still prefer High - usually for dark movies -eg The Irishman" streaming on Netflix  - what a superb movie (If you don't mind lots of language and violence), Academy Award stuff IMHO. Great picture quality, 4K, HDR and Atmos! I was so absorbed that I forgot to check the metadata from the ATV 🙂

hi TR, kris's post below probably sums things up pretty well I think. is is full proof ? probably not, suspect need some intervention some time or other... not that have needed it. but keeping in mind too there are likely some that aren't even mastered best or something screwy going on that needs intervening :)

 

"One also has to remember that this is JVC's first attempt at a true dynamic tone map and I'm actually really surprised how well they did on their first time out. It isn't like MadVR or Lumagen didn't have a TON of updates and approaches with their solutions to get where they are now. Sure it takes some user intervention to get the absolute best performance from the JVC, but the same can be said about the other solutions too (at least in initial setup). I just think if there is anyone here hoping for a one setting fits all with the JVC that they can set and never have to worry about getting the absolute best picture every time, that isn't going to happen. I would just select AUTO and if you start watching a title that doesn't look quite like you want, try one of the other settings and see if they look subjectively better to you. It doesn't have to be any harder than that."

Tonight I did some more testing. I tried the Spears and Munsil 10000 nit this time on the Sony 4k UHD (for some reason the Panasonic does not register the metadata ) and Auto for me is definitely the way too go. It looked great. There was an issue last night where it looked horrible but I realised where I went wrong I changed it throughout the scene.  I tried Alita Battle Angel and it has  10000/10000 nits and the JVC on Auto it looked great.

we watched top end wedding a few weeks ago on blu-ray and followed up this evening with the sapphires on blu-ray as well.

 

Gosh it comes up so splendidly on the JVC ! such a visual treat with rich colours, punch and detail to the picture. Such a feel good movie. Great music and sounds fantastic to go with the lovely natural images.

Netflix, via 4K Apple TV - just download the Netflix App. I am on the premium plan which includes 4K /HDR /Atmos for some titles. Also tried Disney+ tonight on the Apple TV (7 day free trial available) - some great 4K, HDR, Atmos content on there too.  The streaming wars have commenced folks. I should mention - you need a high bandwidth internet connection for 4k/HDR/Atmos - at least 20Mb/s I believe. NBN if you have it. Lets hope the NBN can handle all the extra traffic 🤔

Looking forward in watching The Irishman. I’m a big fan of goodfellas and Casino. Only problem I have with streaming is the audio is at 800kb ( I’ve been told ) but the discs audio  are higher up in numbers.  I remember watching Tarzan on Apple TV 4K then on UHD and with the disc the jungle came alive.

yeah audio tends to be most noticeable to loose.... discs will have both audio and video way way higher eg upto as much as 128mbps overall :) best netflix can manage is their quote 25mbps but thats more typically much as 16mbps :) disney is quite to being 30mbps which is all better but still not quite where discs capabilities are :) however its good for stuff to check out and maybe not buy :) it can be good for suck and see !

On the whole, I find Netflix audio actually very good (to my 62 yo ears). I have what I consider a high end sound system with Dolby Atmos etc. Netflix is clearly taking the whole matter quite seriously to ensure they achieve "perceptual transparency" ie imperceptible difference to the master recording. There is good info on the Netflix technical blog here:

MEDIUM.COM

by Guillaume du Pontavice, Phill Williams and Kylee Peña (on behalf of our Streaming Algorithms, Audio Algorithms, and Creative Technologies teams) Remember the epic opening...

 

I expect the other streaming services are having to lift their games  too. I was very impressed with some of the Disney+ Dolby Atmos material I streamed yesterday. 

 

I think if you have enough internet bandwidth and the right "streaming box" (I have Apple TV 4K) and the rest of your components are of a reasonably high quality, you shouldn't be disappointed.

If it’s any conciliation TR the older you get the bigger your ears become ( I know cause I’m pushing 63 next month, oops this month now ) so should mean your picking up more audio signals than our younger counter parts on this forum. 😃

talking about disney... we watched brave on uhd this afternoon. have watched it prior on blur-ay on older gen jvc. this time on the 4k jvc and atmos all can say what a stunner ! the picture is (i know  a 2k given its CGI) was truly stunning. the colours and details. and audio wise too so enveloping and dynamic. great experience :)

Its good to see Netflix putting in the effort for the audio. Looking forward when they get to disc quality.

watched mandalorian on disney streaming, doing the free trial. there was some talk on avs it was a bit dark. plenty of dark scenes indeed, but the JVC rendered them all beautifully i thought. only watched the first episode tonight. also was it the case no atmos with this one, will check again with the next episode - shame if the case.

Downloaded the 1st 2 episodes Al ; not streamed 😉and the 1st episode was dd+ with atmos according to media info the 2nd was straight dd+ . Was enough to upgrade my tvix to a zappiti so I am future proof :cool: Cant speak to the source though ; hope it comes good for you  :)

Just setup N7 and have a few questions.

I can output resolution of (i) 3840 x 2160 50Hz or (ii) 4096 x 2160 24Hz from the Minix unit.

Running in (i) I can completely fill the scope screen without much spill.

Running in (ii) I have to lens zoom to fill the scope screen with spill on both sides, or zoom out and be left with black bars top/bottom on scope screen.

(i) also seems to run smoother on most content but I've yet to play enough.

 

Thoughts?

2 things to consider ; the jvc's native resolution is 4096x2160 and the 4k bd resolution is [1]3840x2160 so its a choice of letting the jvc or minix to do the scaling . Shame the minix cant do a 3840x2160 24p passthrough for a native resolution passthrough ; the jvc will do better no doubt so ide pick [1}.

Other factor is the lens control has a different effect than zooming 

Quote

if you do choose the Zoom function bear in mind that it's applying scaling and thus loses some fine detail due to the processing. This is obvious using test patterns but harder to spot with normal content. Having said that, we'd recommend expanding the image to the correct aspect ratio rather than using the Zoom option, thus ensuring the 4K image uses every single pixel precisely.

How this relates to overscan and how much this matters is a personal choice .

Minix can output 24p. It defaults to native res of the video feed on playback.

I’ll play a bit. Time to fire up the Xbox.

 

I’ve also only used the lens control to zoom and shift the picture. I’m assuming that output in (i) means the scaling of 4K material isn’t as sharp as native? Does this also affect light output?

Well theres 2 different resolutions for 4k . One is the cinema dci standard of 4096 and the other is used by 4K bluray [3840] . Like sony ; jvc uses the cinema standard unlike the 4k standard for tv's so there has to be a very small upscale . This is nothing to worry about compared to say the deinterlacing and scaling from 576i pal to 4k as that requires a much more complicated algorithm and you would get artifacts /moire and jaggies [ trying to create detail that isn't there..]

 

Scaling wont effect lumens rest assured :)

Just calibrated my N7 with spyder5 pro last night, took me nearly 2 and half hours. then hooked up with madvr beta for projector on GTX 1080i.

 

the picture is ....the best I have ever seen. it looks like in real theater , that feeling I don't have any words to say it.

 

I watched planet earth and fast and furious presents 2019 last night.

 

It's not output HDR, it's done by MADVR from HDR to SDR. But the picture is far better than my SONY TV。
