madVR - high quality video renderer (GPU assisted)

[Dorohedoro]

Can you double check in the task manager ("details" tab) with user name the madHcCtrl.exe process is running as, and which user name your media player is running as?


Both process are running in the same user name, the active user.

----------------------EDIT--------------

Ok Madshi I got it!

I've deleted every custom resolutions and started from scratch, made the new custom mode (1080p23) on madvr again but this time I followed the Asmodian advice (letting madvr automatically change the resolution every time a new video is open) it worked!!

Before I was using the 23hz mode of the windows picture properties, and went back to 60hz to try the advice Asmodian gave to me, but it didnt worked, it seems if you choose the refresh ratio under windows options first, that choice will mess in some way your recording process, even if you go back to 60hz and let madvr change to 23hz.

So, to resume, if I want this to work I need to let madvr to handle completly the resolution selection without touching the windows resolution properties or the nvidia resolution panel.

Btw, sorry for my bad english, I had a really hard time trying to explain all of this.

Thank you all so much for the help!

Is there any advantage in using D3D11 DXVA vs. DXVA copyback? CPU use seems to be the same between the two, but I am getting a few random freezes/crashes with D3D11 DXVA.

Also according to madVR OSD D3D11 DXVA is not being used on some videos for whatever reason.

[huhn]

d3d11 native decode is in faster than DXVA copyback. for the CPU this is trivial but it may play a role for the GPU.

in my personal experience i'm unable to detect any notable performance differences.

BTW it looks like D3D11 copyback is faster than DXVA copyback. you are activeting D3D11 copyback by selecting the GPU under Hardware decoding in lavfilter.

DXVA and D3D11 can't be used for every video. if you have a file that works with DXVA but not with D3D11 make a sample and post it. make sure you check this in lav video not the madVR OSD.

Is it worth to install the LAV-nightly version to use DXVA2-Native with D3D11 in windows 10 then ?

or should I keep using DXVA2 - Copyback

[ryrynz]

Yeah give it a shot. It's not DXVA-2Native with D3D11 it's either one or the other.

[huhn]

wait for the release of lavfilter there are currently some major drawbacks using D3D11native on madVR site for example no deinterlancing.

i personally recommend people to wait until lavfilter release this feature in a stable build and madVR support deinterlancing with it.

but if you want to test it feel free to do so.

[x7007]

Yeah give it a shot. It's not DXVA-2Native with D3D11 it's either one or the other.

ye I chose D3D11, works fine with NNEDI3 .

Not watching 1080i movies , so it's not an issue.

There are some speculations about "realtime video frame interpolation via adaptive separable convolution" in madVR on *chan.
Is it real or they smocked crack again? :D

Is this the thread you're talking about?

https://boards.4chan.org/g/thread/62280403

It's literally just someone who said they would like it as a feature in madVR. I don't see any speculation.

[ForceX]

I got a new 100Hz G-Sync monitor connected to a GTX 1080 which I have configured to switch to 50,60,85 Hz. However, when it's playing a 60fps video in fullscreen (non-exclusive) on MPC-BE, the queues are all starved (https://i.imgur.com/fjUU2mR.jpg) and I get a couple drop/repeat frame each second. This doesn't happen in window mode or if there's an overlaying element like MPC-BE's seek bar or right-click menu is shown, but as soon as those are dismissed the queues are down again.

Any idea what's going on and how I can fix this?

[aufkrawall]

Did you try disabling gsync for MPC HC only in the driver?

[ForceX]

I had. Just to check I disabled G-Sync altogether and it's showing the same behavior. The only tweaking from nVidia control panel that gives me full queue is having VSync turned Off for MPC-BE, which introduces massive tearing in the video.

Sounds very interesting, this video explains it better:
http://web.cecs.pdx.edu/~fliu/project/adaconv/demo.mp4

Madshi is it possible to implement this interpolate method in MadVR?

[Frexxia]

This video is the one that actually corresponds to that paper http://web.cecs.pdx.edu/~fliu/project/sepconv/demo.mp4. The video you posted is for an earlier paper on a different algorithm.

The paper mentions that interpolation of a 1080p frame takes 0.9 s on a Pascal Titan X, so not quite real time yet...

Edit: I first commented on the video that digitech posted, but it's not the same algorithm as in the paper that was linked.

[Asmodian]

You should have VSync on "application controlled" along with pretty much every setting you can set to that in the Nvidia control panel. Maybe it is one of them?

[aufkrawall]

I don't believe it, but maybe prerenderlimit does have an effect on borderless fullscreen with gsync?
Just wild guessing, but you never know.

[AngelGraves13]

Never enable pre-render limit for video playback. If you need to enable it, then at the very least, for MPC-HC enable "application preference"

[aufkrawall]

I wasn't suggesting to enable it.

Holy crap that is amazing, absolutely add this to madVR at whatever cost for the paid version.

[plasma]

I guess those super advanced interpolation algos will be patented and only used in TVs

[staindrocks]

I was trying to follow madshi's "custom mode tutorial" to optimize my display modes to reduce framedrops, and somehow i messed up bad. Now my tv will no longer display an image from my htpc, and i'm afraid it's stuck on a custom display mode(59Hz) that i modified.

Madshi mentions in his guide that if this happens "we'd have to boot into safe mode then to get the PC to work again, which is of course very ugly". I can boot into safe mode, but i don't know what to do from there to fix it back to how it was before i modified it.

Yeah, i need help! :scared:

In your picture I see a 60fps 4k source, are you sure your CPU isn't struggling?

Otherwise yeah, having g-sync enabled for video playback is bad.

What I do on every nvidia driver install (I always use the clean install option) is add mpc .exe (and jriver .exe in my case) to the official Window Media Player profile (you could use another official profile, such as Internet Explorer or w/e) since this one already has g-sync forced off, fixed refresh mode preferred and v-sync to "app controlled".

When I create a custom profile from scratch for just mpc or jriver I have tons of issues (such as g-sync disabling itself completely upon opening a video).

Boot in safe mode and reinstall video drivers, that's the easy way (and with recent Windows versions all you have to do is reinstall drivers on top of the old ones, so it's not much of a hassle). You can also RDP in your machine and/or use CRU (https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU) to delete the bad resolutions (this utility works in safe mode too).

This profile thing you mention is accessible only when connected to a g-sync monitor, correct?

[clsid]

No, profiles are always accessible. Just certain settings are only applicable on specific systems.

[Q-the-STORM]

As if TVs have nearly enough power to run it.... on a Nvidia Titan X they need 0.9s for one 1080p frame... for x2 interpolation, you'd need to get that down to 0.04s to run smoothly... I don't think any TV could run something like this any time soon...

[el Filou]

TVs and other CE devices usually use ASICs that can process very specific tasks much faster than GPU compute units, so it's not impossible but it will probably have to wait a few years.

Chroma Upscaling NGU - Sharp Very High QualityIMHO this is a waste of processing power and Medium is enough for chroma in real content.
Did you test and compare?

Should I use NGU or NNEDI3 32 neurons ?madshi says NGU has a better quality/performance ratio.

[knightvision]

Hi Guys,

I used an older version and there i had always a TAB for HDR settings in MADVR. But now i donwloaded the newest madvr on your website and have activate it an deleted the older one.

But now i see no HDR Tab and options for HDR anymore.
How can this be? :scared:

[Chroma Upscaling NGU - Sharp Very High Quality


Use NGU AA High or Medium for chroma, you can thank me later.

[x7007]

I will check..

[aufkrawall]

madshi says NGU has a better quality/performance ratio.
I think that's also consensus with users who compared them.
Still, I really like Jinc for chroma. Actually I still like it a lot in general since it's so low on power drain for scaling most things up to 1440p and doesn't show too obvious artifacts.

Btw: What is wrong with my eyes? I can't see a difference (means I can't see any dither noise) between any of the dithering settings, and my eyes almost have direct contact with the display's pixels.
Probably this is only an issue for low pixel density devices like TVs? I got a 1440p 27" display (PLS panel without scaler) which doesn't have banding issues (apart from being 8 bit).

No it's not, it's a Core i7-7700k. Besides, I have great performance in widowed mode, it' just fullscreen when I get issues.

I have tried every possible combination in NV Control Panel, nothing seems to solve the fullscreen perf issue when using 60 Hz. I've gone back to 100 Hz. -_-

Alright, I'm not familiar with your specific bug then. I just tried 60hz on my g-sync monitor and no issues even in fullscreen. Have you tried different renderer paths too? dx9 without presenting frames in advance, dx11, overlay?

[thighhighs]

Use NGU AA High or Medium for chroma, you can thank me later.
Hi all, I have some questions.

Looks like NGU AA very popular for chroma upscaling. It really the best NGU-family algo for chroma or choice should be depending on my TV?
Most my sources are high or medium quality, i use 1080p screen and my current settings NGU AA chroma / NGU AA luma for SD and NGU Standard / NGU Standard for anything else.
Should i use NGU AA for chroma upscaling instead of Standard? Can Standard variant looks better for hq-sources? Because NGU AA (chroma) looks "blurry" for me in some cases (compared to NGU Standard chroma) when i use NGU AA / NGU Standard settings.

Sorry for my bad English.

[Siso]

Use NGU AA High or Medium for chroma, you can thank me later.

What about NGU AA low?

[aufkrawall]

It's good for low-res sources which are often low quality in general. For high quality sources like 1080p BDs you likely want to use a sharper mode to prevent blurring of surfaces like red clothing etc.

What do you recommend for 1080p bds?

[aufkrawall]

"a sharper mode" would be e.g. NGU Standard medium or high. ;)

Shiandow afair used a 1080p example of red buddhist monk robes or something like that to demonstrate that even for high quality sources the chroma scaler can make quite a difference.

Sounds good! Thanks. What about image upscaling?

[aufkrawall]

Well, imho basically the same applies: NGU AA/soft for low quality, standard or sharp for HQ sources. Dunno what I would add to that, at some point it's just a matter of taste.

thank you so much
about 576 low quality

[ryrynz]

What about NGU AA low?Performance wise it's a pretty good option if you can't reach NGU AA medium. At that point though I might consider one of the other algos instead, I haven't done any direct comparisons between low and the others but I'm no fan of the sharper algos that's for sure, but it really does come down to your display.. I believe owners of Projectors like Madshi tend to prefer the sharper ones.

[ryrynz]

Shiandow afair used a 1080p example of red buddhist monk robes or something like that to demonstrate that even for high quality sources the chroma scaler can make quite a difference.

That scene doesn't show a huge amount of difference. It's a decent test shot though. There are combo colored/red/black scenes that show large amounts of brightness differences (like the transformers scene I posted earlier in the thread) with different scalers. I want something that looks natural. I'm very happy with what I'm seeing I'm accustomed now to areas where chroma scalers play a large impact in picture presentation so I think I'd pick up when things felt a little off.
