Gotcha. So I get good levels for all brightnesses EXCEPT the ultra bright, which is better than EVERYTHING being dark.

Thanks for your response. Several weeks ago there was a back and forth on this thread with regards to what (if anything) is lost when watching UHD Blu Ray source material in SDR BT2020 (for those with the Panasonic 820/9000 or 900 with an external device such as HDFury). Are you indicating that the MadVR will be capable of even more precise black levels in HDR10 than SDR BT2020? I understand that I'm not able to remap to SDR BT2020 for media streamers (ATV4K, Roku, etc.) with the Integral, but I believe other HDFury devices are able to remap for Netflix & Amazon (etc.), as is necessary.

So I checked the projector, and it has some settings. Moving them around didn’t do anything to the picture that I could tell.

I’ll look at the 820 settings tonight. We might be on the something!

I let the projector warm up for about an hour on my desk before setting up zoom and checking convergence. Everything is pretty close to perfect, had to fine adjust red down a smidge (not whole pixel). QBF pattern checks out perfectly. Looks like this is a keeper and am confident I will not have to take it down so next step is to mount it up.



Quick question for markmon or anyone else using MadVR - are you also playing 4k BluRays through the HTPC or are you using another standalone device (ie UB820).


You moved red half a pixel? Using fine?

madVR has dynamic tone mapping that can be used *right now* and is already fantastic and far better than anything else out there. If it never improves it's great. But yes, it's still undergoing development and will get even further improved. Couple that with the best upscaler probably in the world, I think Lumagen will be good, but I doubt it will be this good.

So how far along has JVC come to pre-orders being fulfilled/delivered? We at the 50/75% mark yet? Obviously it would be a guess for most other than dealers.

I have been using madvr for years now with all my past JVCs, I recently moved up from the X9900 to the NX9.

The auto tone mapping on the NX9 is good, I could never get HDR looking good on any of my past JVCs so I gave up.
I was happy with JVCs new tone mapping for about a week, then I kept hearing how good it was with the “new” test builds on madvr, so I needed to enquire further…
Javs helped me, and unless you know and understand HDR this stuff its very complicated, plus the updates are changing almost daily with the beta tone mapping.

I think I’m now on version 51 and its “out of this world” and that’s not a lie!
As it changes and measures every frame on the fly, the image is always good, even on a fadeout you see the nits on the stats go down to zero, so the image is BLACK, real BLACK.
I have so much light in LOW lamp on my rather large curved 145” wide Studio Tek micro perf screen. Low lamp was impossible with the NX9 auto tone mapping.
The auto tone mapping on the NX9 is turned off and my fade outs go straight to black with DI auto 2.

Yes this is truly something amazing, I’m so happy to have spectacular results finally with HDR using madvr dynamic tone mapping.

I’m no expert on this so please don’t ask me questions how does it do this and that, I just can’t explain those details as I don’t know sorry…
Others on this thread are experts and there are other threads to go to for help, that’s the best place to start.
But be warned, using madvr isn’t for the faint hearted, you need time to learn it, it’s not something you can have up and running over night.
I have spent hours, weeks, months and years perfecting settings, playing test material over and over again experimenting.
My settings won’t be the same as the settings you may need, there are just too many variables….
But if you can put in the time slowly learning it and understanding it, the rewards certainly outweigh the time spent in learning.

Who else here is using the new madvr tone mapping with one of the new JVC NX models?

For those that want to go on the journey this is a good place to start. https://www.avsforum.com/forum/26-ho...tpc-madvr.html
That's right it. madVr latest builds are really something with HDR. It's nothing like anything we've seen yet for projectors.

Yea, that's not how the Anthem work though. Their 2 outputs is equivalent to a Y cable built into the chassis. I busted off an RCA tip into one of my 2 sub outputs and I'd have cared if it weren't this way.

I have seen madvr multiple times recently, and the lumagen 1 time recently. I saw madvr again yesterday with the dynamic tone mapping, which continues to be tweaked. Madvr is impressive, and seems to keep getting better. I still prefer a stand alone unit, and the lumagen will still allow me to use the oppo. Agree to disagree about madvr being far better than a lumagen though. The lumagen is impressive.

I’m glad to see you guys getting yours though, I think we should start our own nx5/rs1000 thread

This isn't the type of thing you're going to hear something quickly. Most likely a couple months will go by and a new firmware will be released.

Questions:

1. Do you worry the increased average scene brightness will go against the directors' intentions for dark scenes? (Though I feel like there are WAY too many dimly lit scenes in TV and movies... WHY?!?)

2. Does that also mean less headroom for the bright/glare spots?
MadVR doesn't change the movie to be brighter as per the directors intent. It tone maps it properly so a projector can play it. The original content was designed for a display that can do 0-1000 nits, in some cases 0-10000 nits. That can't just be played on your 50 or 100 nit projector without some help. The madVR tone mapping is just optimizing this not changing the content.

A UHD movie ripped to disk with just the single atmos english track and not all the other BS audio tracks averages 50gb per movie.

No, I have not seen the new JVC's but I can tell you in depth how MadVR works, and once you understand that it is measuring literally every frame and adapting to each instance, there is no amount of 'static' metadata tone mapping that will even approach it.

Right now, the JVC looks to be applying a set 'curve' for each film you put in. We used to have 1 or 2 custom curves in total and pick the best one based on metadata, now the JVC will read metadata and update is own settings on a film by film basis. it can do this with probably millions of combinations since it uses 3 sliders to do it. But they are static, ONE curve per film is possible, thats it.

But what if the Metadata is wrong - I can tell you over 70% of the metadata IS wrong.

What if the title has a 1200 nit pixel for a millisecond and thus its metadata reflects that, but 99% of the film is around 600 nits peak? The JVC will be tone mapping to 1200 nits and the whole image will be darker than it ideally should be.

MadVR will know this and as it reads and measures the peak of every single frame, it can adapt extremely quickly within 1 frame even if you have it set that way, it can also detect scene changes, there is a whole host of algorithms which juggle and decide when to change the curve for a set event.

In fact one of the most recent things we are doing is having MadVR throw away the top 1% measured peaks, the image suddenly becomes exceptionally vibrant just by doing this. Thats one trick.

Lumagen I think is working on this too so should eventually be playing the same game if not already, but the MadVR development has been crazy in depth and rapid on this for months now, its extremely good. It is pretty much indistinguishable from full blown Dolby Vision now. But it will work for every title you put through it.

I know it’s frustrating, and hopefully we won’t have units that were kicked around or dropped off the truck!

Actually this is one of the BIGGEST things about what it does now too...

0-100 nits will generally, so long as you have that brightness on the screen be actually mapped in real 1:1 ratio.

If the director intends a scene to be 6 nits, it WILL actually be 6 real nits on your screen. Any scene under your entered peak nits value will be shown 1:1 this is far more common than you realise. So if you use a value of 85 like I do, than anything under that will be its real intended brightness. Anything over will slowly begin to scale.

So actually, this is the first time you would be able to see what the director intended!

We used to use a 4:1 or so ratio with custom curves on the old units, which means for a 100 nit scene it would be 25 nits, and a 6 nit scene would be only 1.5 nits. Well not anymore.

Read this post for a little interesting run down on some HDR tone mapping facts, it was in the middle of a small argument about HDR in general so its not directly about the current topic, but it will give you some insight into some things MadVR is doing.

And check this out, this is 350 nits target (An example of what static tone mapping is) vs Dynamic Tone Mapping with Dynamic clipping.

Not only is the entire image brighter, the shadow details are properly there and the neon signs pop a LOT more. This trend follows for the whole film dynamically as each scene comes up, MadVR measures, and knows exactly how to tone map that frame.

But they are static, ONE curve per film is possible, thats it.

But what if the Metadata is wrong - I can tell you over 70% of the metadata IS wrong.

Ok. I get that MadVR has dynamic tone maping. But how about if you compare the JVC’s auto tone mapping to MadVR without the dynamic feature. In other words, does JVC do a good job (e.g. keeping accurate colors/saturations when reducing video levels that are beyond the displays peak output).

I asked above, without anyone responding: Is the new JVC 4k PJ PQ anticipated to be demonstrably better or more accurate with HDR10 via the MadVR versus the same UHD Blu Ray source material via SDR BT2020?

Then if you want to go full panel you reduce the overall image so that the 17:9 image width fits the 16:9 screen. I think we agree here, too. When you display a 16:9 image on that, the top and bottom will show up as bars because the panel is not capable of displaying the full image. So some of the image is cut off. In this case 17:9 panel gives 16:9 with black bars on top and bottom because the panel cant display those.

Ok on 2.35:1 image when you go 16:9 scaling, the width of the screen is filled and the top is black bars for the remainder of the aspect.
If you scale to 17:9 then you reduce the image to fit your screen. The width fits and the black bars on top are the same since you are scaling not zooming.

You do gain ~100 lumens in brightness but its likely not to be noticeable.
You got it. Zoom doesn’t stretch, it fills the whole width of the chip, which is wider than 4K resolution. For people like me who are limited by throw distance, Zoom allows for a bigger 16:9 screen than otherwise would’ve been possible. Assuming I use 16:9 screen, I can get bigger scope image and slightly cropped 16:9.

I know. I am just saying just an internal y-cable connection or two sub outs that allow independent distance and level, it is still just a .1 channel.

madvr is way better as mentioned in my earlier post, there is absolutly NO comparison. But if one doesnt want to go the way of an HTPC using madvr the auto tone mapping is fine on the new JVCs as long as your screen isnt too large. But when you see madvr do dynamic tone mapping you would NEVER go back!

Sorry, for any confusion..... I wasn't asking for further comparison of JVC static tone mapping of HDR10 versus MadVR dynamic mapping. I was hoping for a comparison of MadVR versus SDR BT2020 (no tone mapping) for UHD Blu Ray source material.

I had to move red up one. That helped MOST of the panel. Moving it up one helped 75% of the screen, made the upper right corner/zone off by one though.

Would you consider that a win?
