madVR - high quality video renderer (GPU assisted)

[HauteTension]

1) I suppose he himself is in serious throwings.
Therefore, so far has not given a direct answer.
However, we see the facts.
They are such that the development of MadVR in its usual form has long been stopped.
Algorithms do not develop. There is no support for new formats.
It is not known how long the code will work until the next update of WIN or video drivers
turn it into a useless set of zeros and ones.

You can call it a “project frozen” or something else.
But the facts remains.


2) Actually for MadShi personally, it`t not so bad "businessplan".
As I understand, he got some sort of venture funding for "Envy project" and some share in "madVR Labs, LLC".

It brought enough money so that for about two years not to engage in any other work.
At the same time, without releasing any finished product to the market :)

Are there any real market prospects for this device?
Why, in an era when high-end projectors will rapidly die out under the onslaught of WALL`s, capable of showing real HDR,
someone in this market will need a video processor sharpened for HDR to SDR conversion?
And with a single HDMI-input?
Will they be able to sell more than one or two dozens of these devices?

Who cares?

3) Suppose, after another year or two, it will become obvious that the Envy project has suffered a complete commercial failure.
Everyone in "madVR Labs, LLC" had a good time, but sooner or later the funds will run out.

Will this be a reason to suddenly resume work on MadVR ?
In the free version, after all, it is unlikely.

Perhaps madVR will return as paid software?
But even here the prospects are misty.
Selling "millions copies" and earning 50-100 million euros will definitely not work here :)
On his own site, madshi talks about "hundreds of thousands of madVR users world-wide."
Suppose there are 500 thousand . But these are those who use the program for free.
Usually, only 1-2% of the user base are ready to switch to the paid version.
This is only 5000 people :)
Theoretically, even this tiny base is enough to feed one developer, although this will not turn him into a millionaire.

So back in the realm of actual MadVR questions. For "10-bit" displays that are actually 8-bit + 2-bit FRC, what should I set the native display bitdepth to in the properties section? EDID info shows 8-bit for bitdepth but I'm wondering if I should force it to 10-bit (particularly for HDR content) because it is capable of displaying more colors with FRC tricks.

[Asmodian]

No, 10 bit is not important, even for HDR. Keep using 8 bit to save yourself from extra complications for no benefit.

There's no such thing as 2 bit frc, it's either 8 bit or 10 bit.

the 10 bit can be achieved by 8 bit + frc or 8bit+ High-frc

You don't need to worry about this. Madvr output looks like 10bit even on 8bit.

the 10bit engine on the TV usually doesn't work well or works poorly, while 8-bit support is typically ubiquitous and stable.

Just watched a video news about Nvidia's DLSS 2.0 https://www.youtube.com/watch?v=YWIKzRhYZm4
And I've been very wondering - can it be used to play old low-res 480p videos in mediaplayer? If in games it's a matter of fps - here it's a moon landing of upscaling (if I understand this right)

[huhn]

it seems to be hilariously bad:

[littleD]

Usually most of quite new games are playable on low end gpus. Its enough to turn off vsynch, antialiasing (especially MSAA and variations) and start with all quality on medium which is enough visual quality in today's game engines.
DLSS and Variable Rate Shading are teqniques for reducing quality. That is buisness move. Instead making games even faster on low end gpu, make them look worse, hah.

Keeping to game technologies, I would rather look at something called DSR. Upsample first, then downsample to native screen resolution leaving all aliasing away. Watching 4k movies (samples :) ) on my screen i get aliased power lines and fences and any other thin long lines. I am still about to find fast 4K to HD good quality image scaler.

[claw]

madshi has made available for download and testing more than 100 builds of MadVR since September 2018 and since the last official release.

[huhn]

a cheap downscaler is bicubic 150.
madVR doesn't seem to be using convolution(or what's called) that'S why it can go terrible wrong but it's super cheap even with convolution.

you can try it with convolution in mpcVR.

Mpcvr bicubic/sharp does not antialias.

@claw
I am on laptop with igpu and dgpu nvidia. I have to use igpu dxva hw acceleration decoding. Then i cannot use nvidia card for madvr, have to use intel gpu for scaling.

[HauteTension]

- He could do even 1000 releases per year. Or at least 100 releases per day.
What's the use? Is it at least 1%, somehow improved the "classic" MadVR?

Likely the speech about "Advanced HDR tone mapping" addition?
Well, madshi himself really needs this because he wants free beta testers for the Envy Project.
But hardly more than 5% of those who communicate in this thread really need this option.

[QBhd]

Again... 7 posts from a lurker and we have an expert of this thread? How very interesting...

Also it is never a good sign when people with "beliefs" start spouting numbers... Usually means there is no reasoning with those people since they see their belief as fact.

[HauteTension]

I am not saying that madshi does nothing.
On the contrary, it may work in this area much more than usual.
But what do we care about this job now?
When I say that madVR is DeadVR, I mean the demise of the project in the classic version "for the masses."
This work is for some very wealthy guys who are willing to pay $10K for admission :)

For him promised a lot of delicious new options.
For instance:

1) New, much better CNN algorithms.
True, they are not yet available, while open CNN solutions are developing with might and main and have surpassed any NGU in quality. (http://web.archive.org/web/20191105030230/https://artoriuz.github.io/mpv_upscaling.html)

2) Special algo implemented which has a similar effect as "genlock".

3) Envy has a database of which algorithm costs how much rendering time at which quality level with which input & output resolutions. Using this database, Envy decides automatically which algorithms can be run in which quality without causing the GPU to run out of steam ... Envy does all this automatically, so the GPU is always running at about 85% of its power.

4) More performance with the same hardware.
"Since Envy only uses Nvidia GPUs, I can use CUDA for new algos, or for optimizing existing algos. The HTPC software also has to support AMD and Intel, so using CUDA there isn't really a good option."

5) And - even more.
"In the future, Envy will use Tensor cores for AI processing."

Here is the complete list of sweets (https://www.avsforum.com/forum/37-video-processors/3053602-madvr-envy-anticipation-thread-72.html#post59346350) that are served in a $ 10K pack.
All this could have appeared in the classic MadVR for a long time.
But now it will not appear, because its existence fundamentally contradicts new, commercial interests.

So, what do we care about all these goodies now?

If you think you could do better, you should actually do so and show us. If you can't, then there is really nothing else to say.

[zapatista]

Hi Madshi,

1) for the use of MadVR in win 8.1 (sending 10 bit video over hdmi to a 2e display in full screen mode) does it matter if i use Aero (light), a high contrast theme, or use a default (classic) theme for my desktop ?
i vaguely remember there might be some reasons not to use Aero modes with madvr, but it seems to work better for me atm (when i right click on the video screen playing in FSE mode to alter subtitle settings etc, it seems to disrupt the playing video less)

2) is there any external usb "digital tv receiver" unit that you recommend for use with madvr ? (eg USB DTV dongle type unit)

thank you for your great madvr program, it makes a Big difference in video quality on a good display with HTPC use :)

[DigitalLF]

Sorry guys, terribly busy atm. Just to let you know: My Nvidia driver contact just informed me that the HDR passthrough problems (not always engaging, and incorrect metadata) should be fixed in the next bigger driver release.


TODAY it has been ONE YEAR since MadShi wrote here.. Hope hes doing well and not working to hard on Envy!

[huhn]

this is not the first time this happens just move on and wait until he returns.

if madVR gets scraped, disconnected, returning to the old days or what ever fantasy someone wants to come up with nothing discussed here will change that.

if you want to add your input on this topic do it where is is active now and even talks about it and add your thoughts on it this may have an effect unlike this useless doom saying.

the current stated fact is madVR will continue and the details are unknown most likely even for madshi.

[HauteTension]

Many people have mental illness, be nice.

It seems to me that mental illness is more likely when some people are so blind that they stubbornly believe in the continuation of free gifts
from the good Weihnachtsmann (german Santa Claus :)
Although they are no longer five years old.
And for two years now, Santa stopped harness his deers and sent them to stand as a window of Hi-End AV-salon :)
In addition, even Santa himself directly told them that the distribution of gifts "went sales through the floor" (https://www.avsforum.com/forum/37-video-processors/3053602-madvr-envy-anticipation-thread-73.html#post59405260)
and he "can't just brush off my business partner and all the distributors and dealers."

The situation is absolutely transparent.

But this does not prevent some peoples from believing that they need just have to wait a little longer
and free gifts will soon begin to pour in their mouths :)

Hello everyone,

I need some helps. I have an Intel card GPU is able to do HEVC decoding at 4K 10 bits. I have a video that is HDR 59fpf at 4k. This video play just fine n VLC. I can't play it in MADVR. The problem is probably related to the use of the GPU for decoding.

LAV at 0.74.1

The left pane is the use of the GPU by VLC, the right pane by MADVR. Any idea why isn't using gpu like VLC?

https://i.imgur.com/ifZC0VR.png


Hello,

Just in case it could help a dummy like me, the problem was that lav filter were using copyback. Even with gpu decode, the bus or cpu can't manage copyback for such framerate and resolution. I use MadvR through Jriver and I have some user exit that make possible for me to switch from built-in lav filter with copy back setting and an installed version using native dxva to play really high rate files. However, I'm wondering if there is some script that could change the lav setting dynamically?

[nsnhd]

So, the real problem is Jriver not allowing native dxva ?
How is Intel Iris Plus 655 doing with madVR ? Can it do tone mapping without problems ?

There is an option under the checkbox that enables hardware decoding in JRiver, named "Optimize hardware decoding for performance", if you enable that it'll use DXVA2 Native.

Thanks, that was an interesting read!
The first time I saw proper measurements about different scaling algos.

Unfortunately only madVR NGU Very High was tested, not the much faster variants (High, Med, Low).
It's indeed interesting to see that FSRCNNX is in the same ballpark as NGU algos. FSRCNNX-16-0-4-1 luma is about the same performance here as NGU Sharp High, while FSRCNNX-8-0-4-1 is way faster.

Do you know how exactly (which tools) the actual measurements (PSNR, SSIM, IW-SSIM, PSNR-HMA, PSNR-HA) were created to be able to replicate them? I'd like to try it out here.

And lastly, why was the whole github repo deleted? :)
Edit: it was renamed then renamed again, it's here (https://artoriuz.github.io/mpv_upscaling.html) now

I don't think anything below a 1050ti / 1060 can do tonemapping reliably.

Edit: oh, I found the original here (https://joaochrisostomo.github.io/mpv_upscaling.html)

I've been doing some tests myself related to what I am working on, when I finish I'll post some results with the metrics that I consider most interesting. The performance of NGU sharp very high is usually comparable to FSRCNNX with any metric, the other settings (high, medium, and low) are always a bit below. The other NGU variants produce worse results, but still better than interpolation methods (except NGU soft).

Most of the metrics are implemented in Matlab, there are plenty to try:

hi guys,
if in Calibration I set disable calibration controls for this display, in Color & Gamma do I have to set enable gamma processing?

[Asmodian]

Gamma processing is only if you want to make adjustments, it is not part of calibration. You do not have to enable it, in fact I would not use it unless your screen's gamma is bad and you cannot fix it on the display itself.

Personally I would set your calibration to something, probably BT.709 - pure power 2.2, if disabled looks good for most content.

[tp4tissue]

You need a colorimeter to really mess with the gamma, every display is different, and between the different tv modes, or monitor modes, the gamma and grey balance could change as well. So while you can tweak it until it looks good to you, that's a bad idea unless you've had alot of experience with reference images and know how it's suppose to look.

And catch 22 is, if you are such a person, you probably have a colorimeter.

[amayra]

admin or manager in this forum need to hire special mods for this thread only to keep it under control

[videoh]

keep it under control Ooh, a control freak. Watch out!

[mykillk]

No, 10 bit is not important, even for HDR. Keep using 8 bit to save yourself from extra complications for no benefit.

There's no such thing as 2 bit frc, it's either 8 bit or 10 bit.

the 10 bit can be achieved by 8 bit + frc or 8bit+ High-frc

You don't need to worry about this. Madvr output looks like 10bit even on 8bit.

the 10bit engine on the TV usually doesn't work well or works poorly, while 8-bit support is typically ubiquitous and stable.

Thanks for the info! Will stick with 8-bit.

Although HDR can look pretty amazing, I kind of miss the "old" days before it came out. HDR has made the world of video quite a lot more complicated and uncertain!

[wasper]

Coming from you, it must be right! Maybe, I should reinstall JRiver. I did replace the plugin folder for Lav filter with a more recent version and maybe the flag setting broke during the process. Just to be clear, using regular HQ setting the gpu is used but the decoder queue isn't filled fast enough. What I did, is to change a registry key to move from HQ to custom in function of a database tag. Using custom, it plays 4k 10bits easily at 59fps but without any enhancement! Doesn't need that much anyway for those kind of file.

Appreciate your answer and will definitely have a look how I could have broke this setting or why native isn't triggered, cause gpu is still used with copyback, right?

It should like nevcairiel said. I might missing something there and I'll try to figure out. Not too much time but I'll try to find a program that will tell me the real path from decoding to rendering.

One thing for sure, using custom settings you can use native DXVA with MADVR, so it shouldn't be something to worry. As for tone mapping, I don't use it as I dynamically switch the windows desktop between HDR and SDR in function of the movie content. Anyway, I don't have enough knowledge to give you an answer. Didn't play with windows setting but desktop looks awful in HDR with default settings. Iris is fine as it supports HEVC and VP9 decoding. Intel Nuc is small and pretty, Jriver needs tweaking and some programing skill if you want to customize the behavior exactly like you want(at least for my version but I thing it's fine in the late version). Like the quality of my HTPC. Not sure I answered your question though!

The checkbox is only visible if video is set to ROHQ, because in custom it can't really do anything, and in ROSTD its not needed.
It was added in MC24, the other explanation would be if you are on something earlier then that.

I was too tired yesterday and read too fast your answer about "Optimize hardware decoding for performance" and mixed up with "hardware accelerate video decoding when possible". I'm still on MC21, so everythings is explained! Everything is so fine tuned on 21 that I don't want to upgrade just in case my user exit wouldn't work as expected.

Since you are there, I got a video clip that is 4k HEVC (bitrate at 56312) that doesn't use gpu decoding. Using DXVAChecker, I got this:

Thanks for your advice. I do not have a colorimeter or experience with images.
I am aware that I cannot achieve perfection but thanks to your help I would like to obtain a satisfactory result.

I set in "this display is already calibrated":
- BT.709 and pure power curve 2.20.
I disabled "enable gamma processing".


I take this opportunity to ask you another doubt.
I own a B9 OLED TV. After several tests I decided to use the conversion from HDR to SDR.
Did I have a good idea?
I use these settings:

https://i.ibb.co/ZBCB40d/hdr.png (https://ibb.co/Lxfxj3S)

https://i.ibb.co/0mbfdFQ/IMG-20200407-104022-1-ridotta-ok.jpg (https://ibb.co/tQrbWx3)

In "display peak luminance" I set 80. And in "dynamic target nits" : 50.
Are values ​​too low? Do I lose some details?
For example, to obtain adequate brightness, I could increase the value of the "display peak luminance" and in "this display is already calibrated" increase the value of pure power curve from 2.20 to 2.40. What do you think?
Thanks for your suggestions.

Hi there,
Can someone help me with my profile rules. I cannot seem to get this right...

If (scrWidth = 1920) "1080p"
Else If (scrWidth = 3840) and (fps > 30) "4K_24fps"
Else "4K_60fps"

The 4k 60 profile is never used, it always uses the settings in 4k 24fps. 1080p seems to work just fine.

hi, thank you for your comment.
The conversion from HDR to SDR was not my initiative. I read that some users who own an OLED or LED TV have given up on converting HDR to HDR to switch to converting HDR to SDR.
At the beginning I was very skeptical too like you .. then I made several tests and I had to change my mind.

Hi there. Thanks, but having the same issue. I just copied and pasted what you entered...

It looks like the 1080p is OK and the 4k 24fps is ok.
4k 60 plays the 4k 24fps profile... so line 2 seems to be catching the 4k60 file...?

[Cowboydude99]

When setting up MadVR, I set the HDR to passthrough.
HDR profile does show up on my projector.

If I Control+J the video to see the details, it shows up BT.709 (Best Guess). I'm playing 4k UHD files. I believe they're all BT2020.

Is there a setting I need to adjust? I have the PJ showing in MADVR with calibration of BT.2020.

Also HDR shows "Unknown".

Hi, i've dabbled with this myself and i'm doing that at the moment for reasons I wont bore you with but my OLED is only 450 nits max so Its barely capable of HDR, I would say if you have a new OLED with 700+ nits you should probably output to HDR but also have a play with tone mapping in madvr to pull out a bit more highlight detail.

Ah! That did the trick. I ended up using the following:

if (srcHeight <= 1080) and (FPS < 25) "1080_24fps"
elseif (srcHeight <= 2160) and (FPS < 25) "4K_24fps"
elseif (srcHeight <= 2160) and (FPS < 61) "4K_60fps"

Hi,
Here is a screenshot of the issue with BT.709 (Best Guess).

I have an HDR projector (JVC) and the chain is:

Jriver Media Center + MadVR + SVP4 Pro -- Denon AVR -- Projector.

The PJ turns on the HDR profile.

The files are BT.2020 UDH disks.

Any idea what needs to be changed to ensure BT.2020 color and that HDR is actually in use?

Also, NVIDIA Control Panel = RGB 8Bit Full. 422.74 drivers (Win 10). I am able to change it to YCC422 10bit.

Screenshot below shows RGB 8bit, but I can set it to 422/10bit. It will show in the OSD, but it continues to show BT709.
