madVR - high quality video renderer (GPU assisted)

[digitech]

Anyone have recommended settings for sd content using neddi, i have no clue what combination to use, 90% of my sd content is animation and i love to use SVP with it but if i have to sacrifice SVP for better image quality i will, im on nvidia gtx 760, Intel i5 4670k, 16 gb ram, win7

Any help?

Use ReClock. (or JRiver VideoClock)
Enable 1080p 24/50/60
Drop 1080p 23/25/30/59.

"1080p 25/30" is actually a 1080i 50/60 output.

Sorry, but this won't take more cpu/gpu load?
I have a low budget laptop, and since I see that when fps and Hz are the same I don't get any dropped frame (infact everything is smooth), I was thinking that if my TV was able to set the same refresh rate I could get a smooth playback without changing quality.
Now that I think about it I get (many) dropped frames per second especially on .wtv files (Windows Media Center recording) which show this: http://i60.tinypic.com/n4ws4i.jpg .
Next week I will try dropping those rates, if anyone have more to add, I'll be glad.

Unfortunately changing refresh rates won't help you with dropped frames. It depends mostly on scaling factor and framerate.
Those files are interlaced, so simplifying you get 50 frames that need processing from 25 input frames - twice as much as from progressive files.
To get smooth playback your average rendering stats (45ms on screenshot) need to be lower than movie frame interval (20ms on screenshot).
I would suggest you create profiles for your settings with rules below
if (srcInterlaced) "nice"
else "fast"
That way you can have nicer settings for progressive files and smooth playback (lower settings) for interlaced files.
Or you could create separate profiles for playback on laptop's screen and TV.

I get the same thing, but it seems only if nnedi3 is used, either for chroma and/OR image doubling/quadrupling. Looks fine using jinc3 for example for both.

Think I'm going to revert to an older Nvidia driver, as I've never seen this before. Don't see how it's madvr's fault.

EDIT: Reverted to 344.75 WHQL drivers, and everything's perfect again.

thanks, going back to the older driver fixed it..
but i also had teh artefacts with image doubling , etc..

so it was ether, older driver or using Jinc.
nnedi3 looks much better. so back to the driver..
i guess im gonna open an Nvidia Ticket and hope for the best..

edit:
happy now again with nnedi3 and the C1C3 Stream from the CCC in germony....
MadVR and LAV work awesome with MPCHC and teh streams. never had so good picture quality in a stream..yaaayyy

Turn off smooth motion, it is taxing for lower end gpu.
If you are playing 1080i25 material, 1080p50 refresh rate setting is correct. And that will in turn make smooth option off.

Some option you can try
Cpu deinterlacing using lav
In madvr, check use half frame rate in trade quality for performance.

Why does madvr still contain decoders? Are there benefits I am unaware of? I think with LAV being bundled now it's no longer necessary.

LAV may be bundled with some players, but it is not bundled with madVR. Anyway, to answer the question - convenience, and troubleshooting. Convenience - if you don't want to (or can't) use another third party decoder, you don't have to, just use madVR's built in decoder. Troubleshooting - not sure if the issue you have is due to madVR, or the third party decoder? Disable the decoder and use madVR's decoder. That will tell you.

Thank you everyone, but I still can't use the laptop right now, so I will properly change its settings afterwards.
But meanwhile I want to ask something.
My GPU is capable of i25 (see http://forum.doom9.org/showpost.php?p=1703698&postcount=27887 for details), is there a way to understand if my TV is capable too?
Shouldn't my laptop be able to playback easily a file if source and output are the same? (adding in madVr all the interlaced I support)
Also let me clarify that I never use the laptop screen, and that I disabled Smooth Motion long ago; in case someone is wondering, I have this APU: http://www.notebookcheck.net/AMD-A-Series-A6-4455M-Notebook-Processor.74885.0.html

What is the minimum Nvidia gpu required for 720p60->1080p60 NNEDI3 image doubling? 750ti can't do it, so what's next in line that won't break the bank? I'm thinking of getting a 4K tv, and I don't think any AMD cards can do 4K @ 60hz yet over HDMI. Any idea if this can be updated via firmware like what happened to the Nvidia cards?

Also, can any of them NNEDI3 quadruple from 720p to 4K, or double from 1080p to 4K?

[feelingblue]

If your GPU is not powerful enough, why don't try resolution doubling with ffdshow before madvr (if your CPU can do it of course)?
For 1080p to 4k is a simple vertical and horizontal doubling.
For 720p to 1080p you can try 1280x720 doubling to 2560x1440 then downscaling to 1080p with CR (or what you like)

[huhn]

don't forget older nvdia cards can do UHD 60 hz with 4:2:0 only the new 9XX cards can do UHD 60 hz 4:4:4.

Is there any way to stop MadVR doing any scaling on 4k videos?
I had my laptop connected to a 4k tv at native res and played a 4k trailer and it stutters and I get 110ms render time.
However if I disable madvr its smooth.

My specs are i7 4700hq, gtx860 + intel 4600

I don't know if this is the best place to ask, but there is this new awesome Philips BDM4065UC 40" 4K UHD monitor with 5000:1 static contrast ratio, good response times, 24ms input lag, and excellent color accuracy after calibration. I already have my most-awesome Eizo Foris FG2421 (lucky unit, won VA panel lottery!) for games, but I want this Philips monitor for film playback. I, however, have never seen 1080p content upscaled to 4K through madVR, using the highest quality madVR settings (NNEDI3 chroma & image upscaling/doubling/quadrupling, dithering, etc). Would 1080p content rendered+upscaled to 4K with madVR on 4K monitor/HDTV look better or worse than 1080p content rendered with madVR on 1080p display with identical specs & similar settings? By how much? Would such a monitor be worth it as a TV for 1080p material with its 4K native resolution? I do realize its not true UHD because it is only capable of sRGB/Rec.709 as far as colorspace goes, but 4K is real and of course it uses 4:4:4 subsampling.

Side-question: Is FRC worth anything for an 8bit display (8bit+FRC) ? Can it actually display 10bit content more accurately than 8bit-only display? Is there a way to test whether a display is 8bit-only or 8bit+FRC?

[nevcairiel]

Properly upscaled 1080p to 4K on a native 4K screen should look slightly better than on a native 1080p screen, assuming the screen is big enough and/or you sit close enough anyway.

[Fullmetal Encoder]

How could an upscaled image look better than the original source material at native resolution? Every time I upscale a lower resolution source to 1080 on my monitor it looks worse with at least a loss in sharpness. I'd expect that to be magnified even further going from 1080 to 4k. That's why I've always shied away from considering anything above standard HD for a monitor and have felt the move to 4k wasn't worth very much.

It's interesting that XMonarchY mentioned the Eizo. I was thinking about one of the upper end CG's for viewing SD and HD content (among other things).


Side-question: Is FRC worth anything for an 8bit display (8bit+FRC) ?

Well, as long as the hardware/software works as intended it should be able to present 10-bit transparently to the eye due to the nature of how Frame Rate Control works since it takes advantage of limitations in human visual perception. Because of those visual limitations testing whether a display is using FRC would probably require specialized equipment and the conclusion would be pretty much academic. At least I don't know of any way to test it.

[e-t172]

How could an upscaled image look better than the original source material at native resolution? Every time I upscale a lower resolution source to 1080 on my monitor it looks worse with at least a loss in sharpness.

Because the best image quality is obtained with a gaussian point spread function (https://en.wikipedia.org/wiki/Point_spread_function), which is the ideal goal for an image upscaler. Fixed-pixel displays such as LCDs typically have square ("box") PSFs, which is the exact opposite and possibly the worst PSF there is. For these displays, upscaling to a higher resolution is likely to look better than native resolution (picture size being equal, of course), because you get less of the square PSF of the screen and more of the near-gaussian PSF of the upscaling filter. A counter-example is CRTs which have a naturally gaussian PSF.

That said, for this to make a difference, you need to sit close to the screen, otherwise visual acuity is not enough to resolve the difference in high-frequency spatial information.

If you're not convinced, I would encourage you to read Poynton's excellent explanation on the subject (http://books.google.fr/books?id=Sa-cEY_ZeEQC&pg=PA77).

If you're observing a loss of sharpness, you might want to adjust the parameters of your upscaling filter to compensate for it.

[wOxxOm]

FRC status should be mentioned in the manufacturer's specs on panelook.com site (pdf scan), if you know the internal panel's model number - could be Innolux (http://www.panelook.com/sizmodlist.php?order=panel_id&by=desc&sizes%5B%5D=40&resolution_pixels=38402160), anyway all the 40" 4K panels listed on panelook are 8bit+FRC.

Set a 1080 display to 720 res and start a 720 movie. Now set display back to 1080 and start a 720 movie upscaled to 1080. See?:)

Interesting, so, if I follow you correctly, you are saying that the higher pixel density of a 4K panel allows the panel to more accurately display the higher quality output of the upscaling filter due to the nature of the filter's near-gaussian PSF? So, essentially, the panel acts as a sort of lens which filters the image being displayed. And the quality of the image which reaches our eyes is limited by and can only be as good as is permitted by that filter. And the panel having a square PSF is the weakest link in the chain.

It should be possible then to come up with an objective way to gauge the relative benefit of moving from a smaller screen to a larger screen given that we know the screen sizes and resolutions. I'm thinking that a larger panel would negate the benefit of the higher resolution somewhat. Maybe taking the ratio of each panel's resolution to it's size in comparison would provide a better answer to XMonarchY's question.

XMonarchY it may be wise to take into consideration the nature of the display you linked (that is a PV panel and perhaps more susceptible to gamma shift) as well as how close you will be to the screen. I would expect the gamma shift to be worse the closer you are.

[Shiandow]

I'm not sure why you think a gaussian PSF is the ideal goal for an image upscaler. If that was the case then using a Gaussian kernel for upscaling would be ideal, but that tends to result in images which are quite blurry.

As far as I could find the article you linked didn't claim that Gaussian was best, just that it was better than a box filter.

[Fullmetal Encoder]

Set a 1080 display to 720 res and start a 720 movie. Now set display back to 1080 and start a 720 movie upscaled to 1080. See?:)

The absolute limit of human visual acuity is 0.5 minute of arc, though 1 minute of arc seems more realistic especially with the lower background luminance in a home theater scenario. If you sit far enough from the screen that the pixel size if less than 1 minute of arc (which is a typical home theater best practice (http://carltonbale.com/1080p-does-matter/)), you won't be able to see the difference between a box PSF and a gaussian PSF, because the distance between the centers of the pixels will be less than your visual acuity can resolve.

For this reason, this stuff only makes a difference if you're sitting very close to the screen (especially in 4K!). Basically, if you sit too close to a box PSF screen (e.g. LCD at native resolution), it will appear pixelated; if you sit too close to a gaussian (or near-gaussian) PSF screen (e.g. 1080p upscaled to 4K), it will appear blurry. The latter is preferable to the former.

I'm not sure why you think a gaussian PSF is the ideal goal for an image upscaler. If that was the case then using a Gaussian kernel for upscaling would be ideal, but that tends to result in images which are quite blurry.

As far as I could find the article you linked didn't claim that Gaussian was best, just that it was better than a box filter.

True. Trying to determine the best PSF is akin to trying to determine the best upscaling filter, which often results in heated discussions :) There's no debate about box being the worst though. If I'm not mistaken it's mathematically equivalent to nearest neighbor upscaling.

And when I do, the 1:1 image looks superior to my eyes. That's what I'm trying to reconcile.

I'm not sure what you're doing, but if you want to compare 1:1 to upscaled in a meaningful way, you need to keep the image size the same. Which is impossible to do unless you have two similarly sized screens with different native resolutions. Or maybe you could try using one screen and moving back and forth to keep apparent size the same, but that doesn't sound very scientific!

[Qaq]

And when I do, the 1:1 image looks superior to my eyes. That's what I'm trying to reconcile.
I see. From your viewing distance you don't see bigger pixels on 720. And there are also no upscaling artifacts. Thats fine. But what about lower resolution? You won't set your display to 540, will you?
Personally I hate upscaling artifacts myself. But I can't stand to bigger pixels on 720 display even more. Thats why I always prefer 1080 if possible, even for WEB-DLs. But if I can't get 1080, I'm fine with upscale.

[Fullmetal Encoder]

Yes, but therein lies the rub. If I get 40 inch 4K panel and have to sit so far away from it that the blurriness isn't an issue, then will it be bigger in my field of view (and better) than a smaller panel would be if I were to sit up close to it? If not then where is the benefit in higher resolutions and larger screens? Just buy a really high quality, color accurate 24-25" panel with good uniformity and sit right up close to it. Though all panel sizes being equal I can understand the benefit of higher resolution.

Since visual acuity is expressed in angle units, it follows that the optimal field of view depends only on resolution, not screen size. This means the optimal field of view for 1080p is 32°, and for UHD (~4K) it's - no surprise there - 64°. You can watch 1080p on a >32° field of view if you upscale it on a 4K monitor; you won't get any more detail, but at least it won't look pixelated. If you do the same on a 1080p native monitor with a box PSF, then you won't get any more detail and it will look pixelated.

If not then where is the benefit in higher resolutions and larger screens?

The benefit of higher resolutions (screen size being equal) is, you get a more detailed and less pixelated image, assuming you sit close enough to the screen for it to make a difference (~1 MOA/pixel).

The benefit of larger screens (resolution being equal) is, you get to sit farther away from the screen and still enjoy the same level of detail.

I am very sorry if this has been re-posted a dozen times, but I have been out of 3DLUT-making scene for a while now. I just made a madVR 3DLUT with dispcalGUI 2.6.0.0, but HCFR does not detect madVR. I uninstalled madVR using the included .bat in normal mode and As Administrator. Then I restarted. Then I placed madVR on root directory of drive D to prevent any long directory names with spaces and ran the install .bat file in normal mode and As Administrator. However, none of that worked. When I select madVR as a pattern generator in the latest HCFR 3.1.6, I get an error saying that madVR DLL was not found... I have the latest madVR x.x.11. Maybe all these new connection options need to be used, but I do not see any options for them. I do see my local IP in madTPG - 192.168.1.96. When my Windows 8.1 firewall asked me about allowing madTPG access, I clicked "Allow" for both public and private networks. I also removed and re-installed HCFR Calibration several times in normal and As Administrator, but that didn't help... It keeps telling me DLL was not found and asking me whether madVR was installed...

Please don't yell at me for asking, but how do I fix this problem? I figured the problem must be with HCFR because dispcalGUI 2.6.0.0 detected madTPG just fine when Profiling (reading patterns) for 3DLUT creation. I applied 3DLUT and I can definitely see image differences, which means that 3DLUT is working, but I need to verify its accuracy with HCFR (or is there some other way?). I can't post on AVS forums because they banned me (yes SHAME on me, its embarrassing and I regret it and still feel guilty, please don't rub it n... :stupid:) and I tried 10x times to write them e-mails to get back, but it didn't work and they catch IP's if you try to create another account, etc. :stupid: Please help!

[huhn]

try version 86.10 not 86.11.

and dispcalGUI can this to. just use verify calibration.

madVR seems to be very unstable when playing videos on the 2nd monitor. Though MPC-HC is unstable, too (crashes with EVR CP), but sometimes I get madVR debug window (with "Close application", "Continue" buttons). I remember you confirmed there are issues with the palyback on the 2nd monitor but the main advice was to playback videos on the 1st monitor. Is there any sense to try to reproduce the steps that lead to crash to report it to you, to send you any info regarding the 2nd monitor playback issues?
Many people are doing playback on 2nd monitor without any (major) problems. There are certain issues, like focus getting lost, but there should be no crashes. If you get crashes from madVR (with the "Close application" etc buttons), please always do send the bug reports. But if MPC-HC crashes with EVR, too, it's going to be hard to track down who or what is ultimately responsible.

Hello! i really love MadVR it just gets better and better! but one thing is missing! a seekbar inside the picture area like in a 2.35:1 movie. Why i wonder is because i'm about to order a 2.40:1 screen!

and there are so many bugs trying to watch MKV movies. black flashes, video is continuing rendering subtitles when paused and sometimes the video freeze and audio continues, sometimes it just doesn't continue at all and freeze on the last paused image, and sometimes it just freeze randomly when fast forward or back forward. and sometimes just low performance the renderer is doing 1-7 intead 6-7, and it just dropping frames non stop.

Using Potplayer + MADVR + LavFilters CUVID

So many video bugs I can't watch a movie properly. to fix the video I need to reopen it stop it or switch to JINC and it fix the slow down instant.

With 7970 same settings I didn't have a single issue
If the same thing worked fine with the 7970 then it sounds like an issue either with your 970 or with the 970 drivers. Of course it could also be a bug in madVR, but since it seems to work fine for many other people I wouldn't know what to look for. Generally fixing bugs is hard (or even next to impossible) if they only occur for one user.

Is it possible to use madVR as a video processing filter?
Not at this time.

Is there a person who can analyze madVR bug reports or guide me in analyzing my own to nail down the cause of a crash ?
Yes, me, of course. :p

With the new version of madVR, I can't force film mode for a DVD. Weird.
What happens if you try? Your computer explodes? Some more details would be helpful. Very helpful would also be if you tried older madVR version to find with which version exactly the feature broke for you (if madVR is responsible, that is).

madVR version 0.87.11
I want to use HCFR(version 3.1.6) and madTPG to make a display measure, but it showing this message to me [...]
Sorry, that's a bug in v0.87.11, it will be fixed in v0.87.12.

It is not madVRs fault. HCFR is not updated to version 0.87.11
madVR/madTPG is supposed to be backwards compatible to older calibration software versions. So it's my fault. Which is good, because I can fix it easily.

Dear Santa Claus Madshi,

We have all been very nice this year... so will you bring us presents for christmas ?? :) :)
Hmmmm... Yes, there's a good chance there might a new version out with some nice new features in time for xmas this year... :p

Without the "delay" options checked the queue sizes have no effect on seeking delays. madVR does not wait for them to fill but presents the first frame as soon as it is available.
Yes and no. When pre-presenting multiple frames in advance, after a seek madVR has to wait until all pre-presented frames were displayed, before new frames can be presented. So the number of pre-presented frames can have an influence on the seek times.

In an update to the slow seeking i have.

I notice that if the content is MPEG-2 it's fast like EVR, but with H264 it's much slower.
That's weird. Is this independent on the decoder? And independent on software vs. hardware decoding etc?

Anyone have recommended settings for sd content using neddi, i have no clue what combination to use, 90% of my sd content is animation and i love to use SVP with it, im on nvidia gtx 760, Intel i5 4670k, 16 gb ram, win7
If you're short on GPU power, use NNEDI3 only for luma doubling, not for anything else. Can't say anything about SVP, I don't have experience with SVP.

I'm getting dropped frames every few minutes on a 1080p movie that's 4:2:2 instead of the usual blu-ray 4:2:0

GTX 750ti
i5 3570k
16gb ram

Is my GPU?
In the debug OSD (Ctrl+J), wenn the drops occur, are any of the queues near empty? If so, which ones exactly?

My GPU is capable of i25 (see http://forum.doom9.org/showpost.php?p=1703698&postcount=27887 for details), is there a way to understand if my TV is capable too?
i25 should be the same as i50, which most TVs do support. But I would stay away from anything interlaced unless oyu have no other choice.

I remember there's a way to modify the registry to force madVR to use nVidia GPU with Optimus on some notebooks, but I cannot find it anymore.
That only works for OpenCL, though, not for Direct3D.

How could an upscaled image look better than the original source material at native resolution? Every time I upscale a lower resolution source to 1080 on my monitor it looks worse with at least a loss in sharpness.
It's not a fair comparison to look at an image unscaled and then to scale it up and look at it from the same distance. The real question is whether a 1080p movie looks better on a 4K display or on a 1080p display, when both displays have the same size, and when you watch both display from the same distance. You can't take a shortcut and compare two images at different sizes. That just won't give you a proper answer to the real question.

To get an answer to the real question, read my comment here:

madVR v0.87.12 released

http://madshi.net/madVR.zip

* fixed: v0.87.11 broke madTPG API compatability
* madTPG: added dropdown box to allow manual gamut/3dlut selection
* madTPG: loading a 3dlut now takes immediate effect in madTPG
* madTPG: added API "GetVersion"
* madTPG: added API "Get/SetSelected3dlut"
* madTPG: number of pre-presented frames is now limited to max 3
Sorry, still only madTPG changes.

[James Freeman]

You have absolutely nothing to be sorry about.
Thank you madshi for your time and devotion.

I've had an issue for awhile now where I will play a video in FSE mode and the render time will settle down to say, 30ms for 720p->1080p NNEDI3 upscaling. Then I'll back out to windowed mode and back into FSE and the render time will drop down to a steady 25ms. I'm not sure what's happening but I can reproduce this consistently. I have my gpu overclocked and it's almost like madVR isn't accepting the overclock in FSE even though Afterburner says it's using 1050 core the entire time. No change with v0.87.12. I'm using an AMD 7850 and it happens on all firmware versions.

Does this happen to anyone else?

Sorry, still only madTPG changes.
As James Freeman noted, don't worry, you're doing this for free, after all.
Also, you did (almost) promise us a new version already, after all... :rolleyes:
Hmmmm... Yes, there's a good chance there might a new version out with some nice new features in time for xmas this year... :p
