madVR - high quality video renderer (GPU assisted)

[SirMaster]

Question for those who've used 3DLuts in madVR before:

If I have my display calibrated with an ICC profile (loaded via DisplayCAL), but wish to use a .3dlut entirely unrelated to that ICC profile with madVR, will checking "Disable GPU gamma ramps" suffice to keep the profile and LUT from interacting with each other? If not, will resetting the videocard gamma table on launching MadVR do the trick?

Yes "Disable GPU gamma ramps" will exclude the ICC profile from both the 3DLUT measurement with madTPG as well as using the 3DLUT in madVR after.

[Asmodian]

Yes, "Disable GPU gamma ramps" is the option you want. That means zero out any loaded ICC profile (set GPU LUT to a linear ramp). madVR will also reload the original values when it exits.

You can also attach a custom or linear ramp to the 3DLUT itself and madVR will load those values into the GPU whenever it uses that 3DLUT. This is usually done by default when creating a 3DLUT in DisplayCal (if that is what you are using) and is the most reliable option. When ramps are attached to the 3DLUT the "disable GPU gamma ramps" option does not do anything.

As a side note, windowed overlay (rendering -> general settings) bypasses the GPU hardware LUT. Without "Disable GPU gamma ramps" checked madVR will load the LUT values from the GPU and simulate the hardware gamma ramps but with it checked the values are simply ignored.

The overlay mode sounds nice, but has a strobing/flickering black line in the middle of the screen when I pause playback. Is there anything to be done about that, aside from just using a different presentation mode?

you don't need to, madvr will do it automatically if the dispcal 3dlut has the vcgt box ticked when you create it.

Normally, if the native tone curve and white point of your display is very well behaved, you can just run the default 3dlut profiling, where it sets whitepoint and gamma to "as-measured" in the calibration section.

However, if it's not well behaved, in these cases, it's better to have it meter out the curve and the white point first in the calibration.

There also used to be a bug where if you set the white point only and not the curve, it won't apply either. IDK if this was fixed.

If you have access to 11point rgb balance adjustment on your tv, I recommend using HCFR to set that up as tight as you can before using displaycal. Make sure you do all this in Native Gamut mode.

I have an old OLED 4K HDR TV (LG 55C6) and no video projector. I watch a few 4K HDR HEVC mkv video files, but mostly 1080p non HDR x264 files. I am using HDR passthrough in Madvr settings until now.

1/ Is HDR tone mapping made only for video projector to simulate HDR ?
2/ For 4K HDR TV, can it render better dynamic color for HDR video files better than HDR passthrough settings ?
3/ or can it simulate HDR on HDR TV for non HDR 1080p video files ?
1: no
2: yes (with latest betas (https://www.avsforum.com/forum/24-digital-hi-end-projectors-3-000-usd-msrp/2954506-improving-madvr-hdr-sdr-mapping-projector-299.html))
3: no

Hi, I'm Italian, sorry for my bad english.
I've an htpc with Nvidia RTX 2060 gpu and I use Jriver MP26 with last Madvr release (113) for 2160 upscaling, and hdr to sdr tone mapping for my Sony vpl-vw870es projector.
I've a lot of blu ray discs ripped of concerts and movies. But I can't play well 3 concerts because the source frame rate is 29.970, but Madvr set display mode on 23.980 fps.
I try everything! I create a Profile Group with two display modes, with this rule: if (srcFps > 25) "Profile 1" else "Profile 2"; profile 1 is with display modes 2160p50, 59 and 60, profile 2 is with 2160p23, 24, 25 and 30.
But it doesn't work! Madvr set always that 3 concerts on 23.980 fps, with a lot of dropped frames and stuttering.
The only way to play at the right frame rate is erasing low frame rates in display modes, but then I can't see well all my 23.976 fps videos!
Maybe the issue depends from soft telecine or uncorrect fps data from the ripped files.
Can someone help me? There's a way to force Madvr to set 29.970 (or 59...) fps for that videos?
Many thanks in advance.

Have you tried setting the display switch to:
2160p25, 2160p59, etc?

You list it, but it isn’t the right format, as far as I know.

Edit:
I read your post again. If above doesn’t fix your issue:

23.980 sounds like the composition rate.

My htpc does this too. It may be related to your monitor/tv/projector.

I ended up turning display switched off and always use 60hz in the OS/Nvidia control panel.

Then in Madvr I turned on smooth motion to remove the judder.

If you create an empty file or directory called "DontRenderAfterStop" it might solve it. Another option that might help is "KeepLastFrameOnStop".

You can see the full list of options (if anyone knows one I am missing please tell me!) in the third post of the thread in my signature.

i'm not going to answer that question two times.

Thanks, this was really helpful. I wasn't setting a curve, and apparently really needed to.

I really didn't think something like this would've been addressed in that thread, sorry for not reading it a bit more closely before asking.

Unfortunately the problem persists, but at least the overlay mode doesn't seem to be necessary for my usage.

(Sadly "overlay planes" appear to be a deprecated/legacy feature in modern Direct3d.)

[tp4tissue]

Try using HCFR on the 11point gamma settings on your tv, that really helps.

If you don't have 11 point gamma, at least run the greyscale verification check (use simulated profile is enough), to gauge the tone behavior of the different modes of your tv/monitor.

The LESS work the software correction system has to do on the native response, the better.

I created a directory named frameRate=29p deint=Off and I dragged the 3 videos inside. Now they work perfectly!

[Cowboydude99]

Hi there. I was reading the madvr options explained post. Great info in there!

I had a question because I'm using D3D11 full screen exclusive mode.

The post says:
the native display bitdepth is: [8 bit] This is the bit depth madVR will dither to. madVR offers very high quality dithering so if you are using a low bit depth display (e.g. a 6-bit TN) you may get better quality when setting this to 6-bit. Due to limited support for high bit depths, madVR dithers to 8-bit even when this is set to 9 or 10-bit except when using D3D11 'full screen exclusive'

When using D3D11 FSE, does it use 10-bit dithering if I set the bit depth to 10-bit?

I have my NVCP set to RGB 8b FULL = 60hz.

[huhn]

new version that may notice this may stop using 10 bit in this case because it's pointless.

for your use case you should set it to 8 bit and there is no need for FSE but if you don't have issues with FSE leave it as it is.

[Cowboydude99]

OK thanks!

I created profile groups for the display: calibration, display modes, color & gamma, hdr.

Is it proper to set calibration of the display to the source material or would you just set it to BT2020 for all content?
For example, 1080p BD rips -> REC 709
UDH -> BT2020

I have been playing around with the color (ColorMunki arriving next week).

[Asmodian]

When using D3D11 FSE, does it use 10-bit dithering if I set the bit depth to 10-bit?

I have my NVCP set to RGB 8b FULL = 60hz.

You cut off the paragraph, I do mention that 10 bit works in DX11 full screen windowed as well. ;)

Yes, madVR always dithers from its internal 16 bit data to the output bitdepth. Dithering does not have a bitdepth, it is a technique used to more accurately covert to a lower bitdepth.

Never set madVR to a higher bitdepth than your GPU, your GPU dithers again so you get extra dithering noise. This is better than not dithering at either step but it is best to only convert bit depths once, from madVR's 16 bits to whatever is sent to the screen.

[huhn]

well that's going to be fun.

you set your calibration to what your display is "calibrated" the rest is done by madVr so what ever you are currently doing is well questionable.

i mean for what do you need a profile for HDR. hdr is only used for hdr files so it doesn't effect other that means there is no obvious need for a profile. same for display modes, color gamma...

I see your point.

When I set the calibration to bt2020 and then to 709, it does look different.

I have not actually calibrated yet, but should be doing that next week.

I will revert to no profiles.

[tp4tissue]

What huhn is saying is, right now, switching those settings _assuming_ the display is calibrated to different color spaces will affect color saturations incorrectly.

Your projector as is, is running a rec709 space natively, and it's expecting rgb444 0-255 output from the PC.

If you tell madvr that your display is rec2020, it still assumes rgb444 0-255, so that compresses the saturation inwards.

This difference is not meaningful, because your projector is not rec2020, and isn't expecting rec2020. Even if it is expecting and got rec2020 output from the PC, the projector still only has rec709. Out of gamut will either clip or it will desaturate the edge-colors for perceptual uniformity.

You ordered the "colormunki display " right ? the one that looks like the i1display pro, except black ?

[tp4tissue]

Guys, what is the profile select rule variable/syntax for differentiating between rec2020 and dcip3 primaries to automatically change 3dlut selection ?

If you plugin a rec2020 lut, it always selects that even if the file indicates dcip3 primaries ?

I've been using manual because there arn't that many rec2020 primary releases, but there has been some recently.

Yes the ColorMunki display.

So even though the PJ says it can do bt2020 I should calibrate it to Rec709?

I think it can do only 58% of 2020 though.

[tp4tissue]

Displaycal will profile the gamut of the projector, then its 3dlut is created.

You leave the PJ gamut alone, only for the 3dlut software do you select a source color space. This will affect the way that space is compressed to FIT onto your PJ's color space.

In the case of HDR, there isn't a definitive mapping due to difference in brightness, however, the gamut map does make a big difference in getting visually good saturation.

Since madvr's HDR tonemapping assumes 2.2pure power gamma, if possible you'd also use HCFR to get the PJ's native tone response close to the 2.2

[PimpUigi]

When I switch from 60hz to 23hz my video freezes when I'm using MadVR. Is anyone else experiencing this?

I have to close and reopen MPC.

[THU22]

I recently updated my old nvidia drivers to the latest ones (445.87 and then 445.98 HF).

Since then, madVR does not automatically switch to HDR when I open an HDR video in MPC-HC. I never had this problem before.

I can turn on HDR in Windows and videos play fine this way, but that is a bit annoying. If I do not turn on HDR in Windows, the video is washed out (no tone mapping), but the madVR OSD shows it is playing in HDR. It shows NV HDR, BT.2020 and HDR, unkown properties (this is always like that).

Anybody else have this problem?

[WuNgUn]

I would say that isn't a madvr problem but a driver problem. I saw the same thing last week when I tired them.

[VBB]

Are you using a 10-bit chain? If so, switch to 8-bit, and that should fix the problem with the latest few drivers. See the drivers thread here on doom for more info.

[WuNgUn]

I'm trying to remember... I think it was just the hotfix one that messed up my system.
I tried 8 bit and 10 bit, RBG, 4:2:2...
F×ck it... I went back to 430.xx

Yes I had the same problem and switched back also to previous driver

I guess there is an upside to that. If I want to pause a video and do something else for a moment, Windows in not overbright and blinding, which is the case when madVR automatically turns HDR on.

Also, when I turned HDR in Windows before, I used to get some flashing green artifacts during video playback. Now it just flickers black for a fraction of a second when I go fullscreen (windowed) and then plays perfectly.

Also, with NV HDR I always had the switching to 8-bit problem whenever the player UI popped up or I went out of fullscreen (windowed). But now it always stays 10-bit with OS HDR.

[Harumi]

I would like to run 2 instances of madVR (2 seperate video players) if thats possible.

My use would be/

1st player MPC BE +madVR+SVP (higher MadVR settings)
2nd player (insert name here) + madVR + Dmitrirender (lower MadVR settings)

I wanted to test my videos with higher and lower madVR settings (separately attached to specific player), as SVP is less hardware demanding in comparison to Dmitrirender.

I did test JRiver creates seperate madVR instance-(good as settings are different), but cant add custom DirectShow filter (DmitriRender). On the other hand Potplayer accepts custom DirectShow filters but cant add seperate madVR instance as it gets the same settings as the MPC BE.

Thank you for help thanks:

[shaolin95]

We recommend a 1070 or 1080gtx for madvr's tonemapping.

1060 will work as well, as long as you don't need some of the other quality of life features.

I am currently running a crippled 1060 (crippled as it is the 3GB version). My HDR tone mapping is having issues dealing with the unchecked "compromise mapping" option.
Guess it is all on the 1060 3GB and a GTX 1070 would be good enough of a jump to allow me to uncheck that compromise option while also allowing me to play with the highlight/shadow recovery options?
Also my HTPC only has 4GB of DDR3 ram so I am adding 4GB more and hoping that 8GB will be enough.
Thanks for any feedback!

[tp4tissue]

I am currently running a crippled 1060 (crippled as it is the 3GB version).

You can try overclocking, 1060 should do +150mhz on core easily, if you got a good chip, you can do up to +200 if it's relatively new.

The ram might be a problem, try reducing the buffer. change present frames to 4 or 6 instead of 8.

use lanczos for chroma.

Switch between dxva2 copyback and dx11 copyback see if that helps. < some systems it does nothing, some might shave 2-3 ms>

Also try CPU decoding in lav if your CPU is strong enough for 4K full bitstream Minimum you need a 5ghz 2500k or a 4.4ghz 2600k and above

[oldpainlesskodi]

Wanted to check if anyone else see's an issue I'm having - If I start a HDR movie from the start and bring up the Madvr OSD, it shows the HDR metadata properties, however, if I resume a movie/file, it fails to read the metadata, and say Properties Unknown...

Anyone else have this? (tried windows, fse, all hardware decoding methods and still get the same behavior). Latest Madvr test version, latest lav filters etc.

UPDATE - might be an encoding issue actually, as it only happens on certain files. Never mind.

Thanks for your info.
So I was able to find some cheap extra ram and with 8GB it is a LOT better. I also scored a GTX 1070 for $160 and at that price, I felt it was an easy buy, so I can sell my 1060 and recover some cash.
This made things WAY smoother and now I can research which options will give me the very best IQ at least as far as my system can handle it.
Any suggestions on that? This is specifically for UHD watching..
Thanks!

The next best VISUALLY impactful upgrade would be a colorimeter to utilize madvr's powerful 3DLut color correction feature. (the colormunki display colorimeter is best bang for buck)

The upscaling algorithms in the case of chroma for 4K makes VERY LITTLE difference visually, and at normal distances of 2-3 feet, it makes 0 visual difference, you can try it out for yourself, between NGU sharp very high all the way down to bilinear, you can barely tell.

If you're using downscaling, ssim2d is pretty intensive but should fit within the envelope of a 1070.

Then there's a Wide-Gamut display. This is cheaper than you think, 43" TCLs 5 series are only $200, and the gamut is 93% DCI-P3, it looks alot more vivid than Srgb gamut screens.

I am using a JVC RS520 actually which was professionally calibrated but it does not hurt to try that 3DLUT since I already have the Xrite i1 display pro. Gonna look for a guide to do that unless we have one specifically for madvr that is. :)
Also do you think I am good with 8GB of RAM or is there anything that madvr could do better with 16GB?
Finally here is a photo of stats while paying the movie.
I left Star Wars paying like one hour and when I came back there were 6 dropped frames. Am I somehow pushing it too far off is it normal to do drop a few frames here and there?
Those repeated frames so often doesn't seem good to me. I got my card resolution at 24hz. Maybe I should try 23hz..? I don't want to use reclock, just in case.
Thanks!!

[SirMaster]

I did exactly the same in html / javascript, it requires mpc-be/hc and keyboard shortcuts set up in madvr.
Upload yours, I'll be interested in it. I can do the same...

I FINALLY got this done, polished up, and uploaded.

General HTPC and home theater device remote control from any web browser.

Easy to create buttons for hotkeys to control madVR settings and switch between madVR profiles.

Enjoy everyone:

You are playing 23.976 fps content on a display set to 24 Hz so obviously there will be dropped frames.

Set your display to 23 Hz (it's the windows name for 23.976).

[THU22]

At default 23 Hz you will still get a repeated frame every ~4.5 minutes. You have to create a custom resolution to get it right. Using CRU, I set it at 23.975 Hz, which gives me 23.97585 Hz. This produces a frame drop every ~56.5 minutes, which is the best I can get.

I have been using ReClock for years, but recently I kept seeing random frame drops which did not register on the madVR OSD. I decided to test the custom resolution with bitstreaming, which will be useful when I upgrade my audio setup (waiting for HDMI 2.1). So far I am pretty happy with the change.

You want to get to the 23.976hz mode if the projector supports it.

8gb is enough, as long as it's dual channel.

Run 8bit 444 RGB Full, don'tuse 12bit on the jvc.

Run the 3D lut for SDR lut, select source colorspace dci-p3 or rec2020.

Before calibration, check that the gamma mode/setting from measurement that it's in is Close to flat 2.2gamma @ 6500k.

At default 23 Hz you will still get a repeated frame every ~4.5 minutes. You have to create a custom resolution to get it right. Using CRU, I set it at 23.975 Hz, which gives me 23.97585 Hz. This produces a frame drop every ~56.5 minutes, which is the best I can get.

I have been using ReClock for years, but recently I kept seeing random frame drops which did not register on the madVR OSD. I decided to test the custom resolution with bitstreaming, which will be useful when I upgrade my audio setup (waiting for HDMI 2.1). So far I am pretty happy with the change.
I am going to play with CRU. I was in fact able to get the same as you just with the Nvidia Control Panel BUT for some reason, the custom resolution wont let me use 12bit only 8 where all normal resolutions allow me to use 12. Hope CRU does not have that odd issue.
Thanks!
You want to get to the 23.976hz mode if the projector supports it.

8gb is enough, as long as it's dual channel.

Run 8bit 444 RGB Full, don'tuse 12bit on the jvc.

Run the 3D lut for SDR lut, select source colorspace dci-p3 or rec2020.

Before calibration, check that the gamma mode/setting from measurement that it's in is Close to flat 2.2gamma @ 6500k.
Ok then I will save money..yes it is 8GB dual channel 1600 DDR3. :)

Any reason NOT to use 12bit with the RS520? From reviews I read it actually does 12 bit even if due to other things it ends up being 10bits. Just curious as to why this recommendation.

Ok I am going to try the 3D Lut to see what I get.
I did watch Star Wards yesterday and it was looking stunning, so much better than when I was using the projector HDR mode.
Thanks so much!

That is great but in reality, it does not. I would be very happy if it was giving me 23.976 I would have no repeating frames. ;)
