madVR - high quality video renderer (GPU assisted)

[Klarerwind]

PotPlayer crashes when I try to play a certain .mkv H264 file. I used these instructions (http://imouto.my/configuring-potplayer-for-gpu-accelerated-video-playback-with-dxva-or-cuda-and-also-high-performance-software-decoding/) for playback with madVR. Not sure if it is a LAV problem or if it is madVR. See below link for the sample file; it crashes around 00:00:09.

This file plays without problems on a fresh install of the latest VLC. I don't have problems with any other videos, just this one.

Klarerwind's crash is related to subtitles. Any code based on VSFilter 2.x and prior has the potential to eat up multiple GBs of RAM rendering the \clip gradient in those subtitles, potentially leading to a crash. In Klarerwind's case, PotPlayer seems to crash as soon as RAM usage hits 1.5GB. MPC-HC shouldn't crash unless it surpasses the x86 memory limit (2-3GB).

xy-VSFilter fixed the cause of high RAM consumption in 3.0.0.41.

[Superb]

Plays well here too. No Crash.

Thanks, cyberbeing. I do see the spike in RAM usage (1.4GB). So I guess there's no way to get around this other than using MPC-HC instead? I don't see the VSFilter.dll in PotPlayer's folder so I assume it is hard-baked into the application. I don't know where I can file a bug report on PotPlayer either.

[huhn]

@klarerwind which subtitle render did you use for this sample?

does it work without subtile?

[cyberbeing]

So I guess there's no way to get around this other than using MPC-HC instead?

Using the MPC-HC ISR may not crash, but it still will eat ~2GB of RAM and have poor performance rendering that gradient.

You can use xy-VSFilter with PotPlayer if you want. Use the xy-VSFilter Installer (http://code.google.com/p/xy-vsfilter/wiki/Downloads?tm=2), set "DirectVobSub (auto-loading version)" to prefer under Filter Control -> Custom Filter Manager, under PotPlayer's Subtitle section uncheck "Show Subtitles" to disable its internal subtitle renderer, and finally under "Filter Control" set "Built-in Video Processing" condition to disabled.

That solved the crashing problem, thanks. The problem I have now is that subtitle quality is noticeably decreased (blurred) because the subtitles are being rendered at a lower resolution and then are upscaled with the video via madVR. Is there a way to render the subtitles after madVR and then overlay, instead of before madVR? Upon doing some quick research, it seems there is no way to do so.

[cyberbeing]

xy-VSFilter is a transform filter, so it's restricted to rendering subtitles at video resolution. Using a sharp "Image Upscaling" algorithm in madVR with anti-ringing enabled will help a lot on 720p and greater video. If you watch mostly DVD and low resolution content, you may choose to temporarily toggle back on the PotPlayer ISR for such content if it bothers you.

* added support for new subtitle interface (e.g. for future xy-vsfilter build)

xy-VSFilter is currently working on finishing up support of new subtitle interface which will allow madVR to overlay the subtitles. Maybe in a few weeks there will be an early build for beta testing, but we'll need to wait and see how well things go.

I'm very interested about this feature. I don't want to go off-topic so I'll just ask one question: could you tell me where would I be able to follow this development or be notified when it is available?

Hi, can anyone try reproducing this issue if you have similar settings to this.

I am using madVR with mpc-hc. I have madVR set to delay until the queues are full. I have madVR set not to wait for 3 seconds go to full screen exclusive. I have mpc-hc set to go straight to fullscreen.
In essence, when I open a video clip by double clicking it, it starts straight in FSE mode, and I see no frame drops.

The Problem: If I am opening a video for the first time after the PC boots up, the switch to FSE seems to take like 6-8 seconds. I see a pure black screen and can hear audio going on in the background as this is going on. I can see madVR drops no frames, just I basically miss the first few seconds of the clip.

Any subsequent opening of the video doesn't show this issue, its like it needs to do something extra the first time it goes into FSE thats not needed afterwards, it only happens the first time I open a clip after the PC boots up. I'm using NVidia GTX 295, and have had this issue in both Windows 7 and Windows 8 64bit.

[Duffy Moon]

Could it be your display changing refresh rate?

[MSL_DK]

I can see there is a new update to ycms it eliminates not my problem.

I am far from sure I do it right. Is there a guide to it? From the settings in HCFR to settings in madvr while taking measurements in HCFR to settings in madvr after having entered values ​​in ycms? I'm pretty confused :-P

[Belsel]

Sorry for coming out of nowhere, but since this topic is active I thought this would be the best place to ask. When I change the video renderer to madVR, I get a black screen and the following error “madvr reports creating direct3d device failed.” Can someone tell me what the problem is?

[Qaq]

Belsel, have you read the requirements?

[mark0077]

Could it be your display changing refresh rate?

No I only use 60 hZ. I don't use any display rate switchers. I interpolate everything to 60 hZ. Be good if there was some reason for it and maybe a workaround..

[Belsel]

Belsel, have you read the requirements?

Yes, I did.

What's the recommended GPU for using madVR smoothly at max settings? I was looking at a GTX 670 but if I'm going to have to keep upgrading the card then I might as well get something cheaper that still does everything madVR wants it to do. The only GPU intensive stuff I do is madVR and some 3D rendering (which is pretty slow with my current GPU). Also, will I benefit from using two or 3 cards in SLI for madVR and rendering purposes? I haven't done a build in years which is why I don't know about the new recommendations. Thanks.

[Ver Greeneyes]

(please, no-one suggest ArgyllCMS...)
Out of curiosity, why not? What alternatives are there? Right now my monitor is calibrated using dispcalGUI which is based around Argyll CMS, using an X-Rite ColorMunki Photo, and I had a lot of trouble getting a reasonable result near black. I love the amount of verification and customization that dispcalGUI gives me (as opposed to the official software which gives none at all), but if there are alternatives that could give me a better result I'd love to know about them.

I and many others have settled for GTX 660. That will do fine with Jinc4 luma + chroma 720p to 1080p. If you have bigger upscaling I don't really know.

I plan to upscale to 2560 x 1440 @ 60Hz. And I will probably turn on the anti-ringing filter for chrome and luma.

[leeperry]

BTW, I've plugged a whole bunch of Sammy TV's these past few days and the first one in mVR's config was called "Écran Plug-and-Play"(PNP screen, generic windows monitor name), the second "Écran Plug-and-Play (1)"....instead of deleting the first one and then renaming the second one, I removed "(1)" from the second one then planned on deleting the first one but madHcCtrl.exe instantly froze to death as soon as both screens had the same name :o

[jmone]

FYI - I was just testing some 2K and 4K h264 test clips (to a 1080 screen) and noticed that the settings for chroma upscaling are used for downscaling as well (unlike image that has seperate up and down settings), so the title could be "chroma upscaling/downscaling"

I'm hoping that CalMAN v5 will improve upon that, but ICC creation doesn't seem to be implemented in the current build yet though.

And for the best results when downsampling, use Catmull-Rom with both the Anti-ringing filter and Linear Light scaling enabled for Luma.

[frozenice]

OK, thanks. Very strange.

If I select 1080p24 on the desktop, madVR reports that as being 24.0x when running windowed, but when it switches to FSE, it changes to 23.9x (same thing for 1080p60)

Hey 6233638,

i have exactly the same issue since i use windows 8. With my old OS (Windows 7 x64), i never saw this issue.

Have you already found a Workaround for this? For now, Nvidia doesn't release a Driver who fix this :(.

[Ver Greeneyes]

Damn, I can't afford either of those at the moment. Thanks for the advice though. You're saying CalMAN v5 doesn't include ICC creation even though it's already being sold? (when I first read your comment I assumed it was a free alpha build or something)

[6233638]

Have you already found a Workaround for this? For now, Nvidia doesn't release a Driver who fix this :(.Unfortunately not. I just tried installing beta Nvidia drivers today and it's still switching to the wrong refresh rates.


Starting with my display at 60Hz, if I use the refresh rate changer in any madVR configuration, it will switch to 23Hz rather than 24Hz. (or 59Hz rather than staying at 60Hz)
When restoring the original refresh rate, it sets the display to 59Hz instead of 60Hz.


With the refresh rate changer disabled, if I start playback with my display at 24Hz, it works correctly in windowed mode. If it then goes into Fullscreen Exclusive mode, my refresh rate is changed to 23Hz.
Upon exiting playback, my display is left at 23Hz.


Similarly, even if I leave my desktop at 60Hz, and disable the refresh rate switcher entirely, it will switch to 59Hz when playing back 24p content, upon entering Fullscreen Exclusive mode.


So it seems that both Fullscreen Exclusive, and the refresh rate switcher are broken in Windows 8.
Damn, I can't afford either of those at the moment. Thanks for the advice though. You're saying CalMAN v5 doesn't include ICC creation even though it's already being sold? (when I first read your comment I assumed it was a free alpha build or something)It looks like they actually have a "final" build out now, but when I purchased an upgrade a month or so ago, at a discount, it was a "release candidate" build. It still doesn't appear to be in there yet though.
Edit: looks like the "discounted" upgrade price is now the standard upgrade price: http://store.spectracal.com/consumer/additional-year-of-maintenance-and-support-calman-enthusiast.html

Hi madshi, here's a zip file of a 1.0 gamma .cal file that you can fire up using "dispwin.exe 1.cal"

"disable gamma ramps" works as intended so all is well :)

So apparently Sammy didn't document too much on the latest video engine they use but they did talk about their older DNIE stuff:

Motion Optimizer
Fast-moving images are optimized to produce more natural-looking motion, thus reducing video noise or blurring.

Contrast Enhancer
Brightness and contrast levels are enhanced for deeper, richer blacks with greater detail and more natural whites.

Color Optimizer
Colors are reproduced with a more lifelike realism, whites are more accurate, and skin tones are given a more natural hue.

Detail Enhancer
DNIe analyzes video signal elements to produce sharper detail, clearer image separation, and more natural edge transition.

It's a bit like this video of a much older version of it, except that whites are never burned, blacks are never crushed and nothing pumps whatsoever: http://www.youtube.com/watch?v=ppKDqer2zs8

It seems to boil down to SD/HD automatic detection, noise reduction, black frames insertion, lag-free intra-picture slight dynamic contrast maximizing, super-resolution based on motion estimation in order to improve clarity, etc etc....I still can't believe how clean and natural looking noisy SD gets with mVR + Reclock :scared:

There would be no point whatsoever to do it in 8bit and I guess it would require a team of engineers working on it for years to add something like this to mVR...The stunning video engine that's currently embedded(can't be disabled and active on all inputs) in the latest Sammy's has taken them over a decade to polish. Mix it with a >3500:1 native CR and prepare to be :eek:

When will Jinc be supported?
I'm back on CRT atm and prolly gonna buy a cheap 720p DLP so Jinc3 AR downscaling would be amazing if any possible indeed.

:thanks:

Jincs properties are quite different when downscaling, so it might not be what you wish for. :p

[dansrfe]

A GTX 670 should be able to handle all of madVR's max upscale/downscale settings, particularly upscaling from 1080p -> 2560 x 1440 @ 60Hz right?

Anyway, I overlooked this little baby: http://www.comtech.de/HiFi-und-Heimkino/Beamer-und-Projektor/Beamer/BenQ-W1070-3D-Full-HD-Heimkino-Projektor

1080p, DC3, 6X wheel, xyY based CMS(primaries/secondaries), it looks like a banger (http://www.audiovideohd.fr/album-Benq,W1070/17115.html) :cool:

[6233638]

I'm back on CRT atm and prolly gonna buy a cheap 720p DLP so Jinc3 AR downscaling would be amazing if any possible indeed.I think you are really underestimating how good Catmull-Rom is with the anti-ringing filter and linear light scaling enabled.

I would be surprised if Jinc is an improvement over it, particularly when using linear light scaling. (Linear light scaling is very important when downsampling.)

[MSL_DK]

Sorry I continue with ycms

but I can not understand it. Using HCFR, ColourCorrection.xls, mpc-hc and shaders, I am able to achieve an almost perfect gamut

But HCFR, mpc-hc, madvr> ycms (Yxy) goes badly wrong. All shaded areas have tremendous surplus of green and A4 - Color Clipping looks completely wrong.

What I do is to disable calibration controls and GPU gamma. Then I take measurements in HCFR (mpc-hc>madvr) and insert the values ​​in madvr> ycms. I have downloaded the latest version of ycms and placed it in the folder madvr

I really hope I can find out what I'm doing wrong :confused:

EDIT:
Now I ask really stupid. Should I calibrate my monitor using a blu-ray player. and read these values ​​and insert them into ycms. Or can I calibrate using mpc-hc> madvr and paste values ​​from hcfr

I'm using NVidia GTX 295, and have had this issue in both Windows 7 and Windows 8 64bit.

I, kind of figured this out, incase anyone else sees it. I have my Windows 8 / Windows 7 desktop set to 60.0 hz and interpolate everything to it using avisynth / SVP. I don't use any other display hz but 60.0 hz, but when madVR goes to FSE for the first time, my display gets switched to 59.90 hz. I have madVR's display mode switcher completely disabled. Is this madVR thats mistakenly switching the display rate, or something wrong with NVidia drivers?

[dansrfe]

What are the benefits of using SVP and will a GTX 670 be able to handle all max settings in madVR, especially when upscaling from 1080p to a higher resolution?

Is this madVR thats mistakenly switching the display rate, or something wrong with NVidia drivers?Unfortunately I think this is a Windows 8 or driver bug.

If I disable FSE and the display mode switcher in madVR, and use the MPC-HC switcher instead, the same thing happens.

It doesn’t switch to 59Hz when playing back 30p at 60Hz like madVR does (the display is already at 60Hz by default, but madVR still switches upon entering FSE) but if I start with my display at 50Hz, it will switch to 59Hz rather than 60Hz for playback.

It also switches to 23Hz rather than 24Hz.

However, unlike madVR, it does manage to restore my display to 60Hz after playback. (madVR "restores" to 59Hz)


If I had to guess, Windows 8 must be doing something different with how it's handling the requests to switch resolution/refresh rate, if MPC-HC is somehow managing to restore resolution correctly, but not switch correctly. (I guess restoring reads the current value and restores it, rather than sending a "switch to 60Hz" command)

[agustin9]

I have a problem using PotPlayer.

With "delay playback start..." enabled, resuming play after pausing takes too long, while in mpc it doesn't. This happens in FSE.

[frozenice]

Hmm... I found this Microsoft KB Article in a Nvidia Driver Changelog under a Section "Non Nvidia Issues". This Article is related to Windows 7, but i think in Windows 8 is the same "Feature".

http://support.microsoft.com/kb/2006076

Before changed to windows 8, i dont remind this Issue. Possibly i must install windows 7 on a Second hdd again, to verify if it works fine as i expected before.

Switching worked correctly in Windows 7, and if I change refresh rate via the Nvidia Control Panel, it switches to the correct rate, as verified by madVR's stats in windowed mode. (60/24 rather than 59/23 when madVR switches rate, or enters FSE)

Thanks

[pirlouy]

Motion interpolation sucks. Is it a good answer ? :-)

[ryrynz]

That depends on the content and the algorithm, you'll be watching higher frame count content in the future which will look similar.

Well I can only actually test what I have. With a GTX 680 I get max ~40% GPU usages doing 1080p30 -> 1440p30 Jinc4 Luma + Jinc3 Chroma (both with AR enabled). I usually like Jinc3 for both but Jinc4 is a pretty small performance hit anyway. The GPU is close to full power running at ~1Ghz. I have not tried any 1080p60 content.

I use yCMS calibration, gamma changing, and no quality for performance options.

The difference between a GTX 670 and 680 is very small, I am sure a GTX 660 Ti would be fine for Jinc4 1080p30->1440p30. It should even be at only ~50% load. 1080p60 is more of a question.

[dansrfe]
