madVR - high quality video renderer (GPU assisted)

[XTrojan]

madVR is limited to 10 bit output no matter what.

the GPU driver is limited to 12 bit for the usual refreshrates/resolutions.

the HDR NV API or the HDR OS API have nothing todo with this.

I see. I just saw 12Bit output when NV HDR API was enabled.

I tested both APIs and can't really tell a difference between the two APIs (If Windows api ignores metadata). My TV is limited to 400 nits ( Samsung JS9000 ). Anyone can test both APIs with a higher brightness TV to confirm if there's a difference?

Use FSW for everything else.

Why?
Thanks.

I imagine that the "2.35:1 35mm film" sign tells me that black bar detection is actived ...

https://audioquality.it/cloud/forum/bb2.jpg

The strange thing is that I still have black bar detection also if I change "hardware decoder to use" to none or D3D11.
Is it not only a feature of DXVA2 copyback?


happy new year.

Anyone can tell me something about this?
I want to know if it's possible to have black bar detection also without copyback.

thank you

[el Filou]

You have to think about it the other way: black bar detection doesn't work with 'native' GPU decoding (e.g. DXVA2 Native, or D3D11 with Automatic setting). It works in all other decoding modes.

[brazen1]

Why?
Thanks.

One typical real world example why FSW is better than FSE that you can test yourself (and I hope no one is offended for the somewhat OT post):

You can probably recreate this by just right clicking your mouse in the player field but here is exactly my method and why it affects me:

Set FSW in madVR by turning off FSE.
Play a title.
Bring up the madVR OSD.
You will see 'D3D11 fullscreen windowed'.

I have mapped keystroke 'C' to assign 'player menu (long) for MPC-HC/BE in the players 'keys' options. During playback when I press it, I have access to the players menu to navigate and select any option. I use it for subtitle selection mainly. This key also matches the context menu in KODI fwiw when harmonizing remote control functions. You can just press 'C' on your keyboard once you entered that keystroke value in MPC keys option if it doesn't match the 'menu' button on your remote for some odd reason.

So, during playback without interrupting, I press the menu key on my remote once and the MPC menu overlays on top of the title in progress allowing me to navigate with the directional keys to what I desire and all is perfect.

Now set FSE in madVR.
Play a title.
Bring up the madVR OSD.
You will see 'exclusive' mode.

Press 'C'. You will notice the screen flicker a couple times. This is because it's trying to come out of FSE and go into FSW. The menu interaction only works in FSW.

Ultimately, it isn't going to go into FSW, you'll be returned to your movie in progress, without the menu displaying and managed to do nothing but create black screen flashes for nothing and miss what was playing during the fiasco.

You can fiddle doing this procedure if you time the button pressing 'C' multiple times and if you time it just right, eventually it will switch. Once it has finally come out of FSE and into FSW you will notice madVR OSD shows it's not in FSE anymore and has switched to FSW and you can finally access the menu you've been struggling to navigate to. Once you've made your selection in the MPC menu it has to come out of FSW and back to FSE which exhibits more screen flashes and once again interrupts playback of the movie in progress. It's really a mess tbh.

I think the best thing to do is use FSW vs FSE when you can. I'd use it for all file types except UHD HDR and 3D MVC requires FSE in my environment. So, I set up profiles to make the selection automatic.

Happy new year!

Long time user of this wonderful renderer. I'm using it with JRiver.

For some reason when I upgraded my GPU to an Nvidia RTX 2080 Ti, MadVR will periodically refuse to go into FSE, and instead uses Windowed mode (despite the correct settings being used). This is always fixed by a reboot.

I think I have this narrowed down to this item from the logs:

00018740.081 Render D3D11 fullscreen windowed (8 bit)
00018740.081 Render covered by some windows
00018740.083 Render madVR window [madVR] {0,0,3840,2160}
00018741.395 Render covered by explorer.exe window [ThumbnailDeviceHelperWnd] {0,0,1,1}


I "think" that MadVR sees this ThumbnailDeviceHelper window (hidden from the windows user), and then subsequently does not enter fullscreen exclusive mode?

This is verified by rebooting my PC which gets rid of this hidden explorer.exe window and then all works correctly and FSE works. But, of course this is windows we are talking about and the helper window randomly reappears...?!?

If someone can shed light on this hidden window and how to stop it in Windows 10 LTSC that would be great. MadVR logs and system info are found here:

The OSD says the GPU can't keep up, so I don't know what the problem would be. Try reducing your setting for chroma upscaling and see if the rendering times come down. There must be some sort of bottleneck causing those rendering times. fullscreen exclusive mode isn't reliable on Windows 10. That is most likely the issue.

Thank you, without the exclusive mode it working if i start in windowed mode and then i go fullscreen, if i launch directly in fullscreen i have the same issue but i quit fullscreen and go fullscreen again and it works. I don't know what can be happening. Only happens with 3D MVC mkvs

Have a problem for playing at ~1.5 speed - have a lot of dropped frames. But GPU and CPU does not loaded on 100%, it's about 70-80%. How to fix that?
Using potplayer


My config: Win10 x64, i7, hd4000, laptpo

@Dreamject
Perhaps one of the cores is fully occupied. Or there are limitations on the speed of "video memory". I hope your memory works in dual channel mode?

Sorry i've created theme, but it makes me crazy %).

Now I have 4+2 gb .

I disabled every image improvement, actually I deprove video (enabled such thing as nearest neighbor. OK, gpu load is about 50%, but it still show me dropped frames. EVR-CP or OpenGL mode, instead, shows 0 dropped frames... :devil:

[Dreamject]

Also, I see something strange in statistic. If I use usual render (without SVP) I see same rate at output as movie (24hz) with 1.6x speed 38frames. With madshi I can see random value, like 60, 200, etc. Even if I stop playing, output value increase

Hello, I am trying to get bitstream audio to sync for 23.976 HDR mkvs but having trouble. I am using a custom timing in madvr that shows as "perfectly optimized" but the audio is still off. I have tried different nvidia drivers, different timings, and tried selecting the auto a/v sync correction but nothing seems to work.

Any advice?

[tp4tissue]

Hi guys, I'm trying to use a 3DLut for HDR, (NOT converting HDR to SDR).

However after I created the LUT, Madvr doesn't seem to load it..

For example if I play an SDR movie, it will load my SDR Lut just fine.. toggles on/off, see a difference

But with HDR movie, it kicks the tv into HDR mode, that's good, but it won't load any LUT at all, I press the toggle 3dlut button and nothing ?


I am using HDR passthrough metadata, is that the problem? does that skip the LUT ?

[Snowknight26]

etc6849,

Download WinLister from http://www.nirsoft.net/utils/winlister.html, find the entry that corresponds to that hidden window, then note the process and thread IDs (they're hex, so covert to dec).
Download ProcessExplorer from https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer, double click on the process that corresponds to that process ID, then go to the Threads tab and find the thread (TID) that corresponds to the thread ID you noted. The Start Address column should help narrow it down to the offending DLL (which can help narrow it down further).

[huhn]

for HDR 3D LUT you need to select tone map HDR using an external 3D LUt.

which has to rework the meta data and send new ones.

you currently can't passthrough and 3D LUT at the same time.

just think about it how should this be done?

Thx for clearing that up.

I didn't realize that's how it works, because there's a slot in the regular 3Dlut page for Rec2020..

So how would I go about using the Slot that isn't the tonemap page ?

I'm talking about the calibration page, vs the hdr page..

If i want to use the rec2020 slot in the calibration page, how do i go about that.

[huhn]

the bt 2020 in sdr is for well BT 2020 sdr it's that simple a HDR->SDR should be apply able for this .

i won't load anything in there your screen can't do bt 2020 anyway. i will start using this when screens start to do more than dci p3.

not sure why you want to use that slot. you should not think about using a slot more about how to realize what you want to archive.

Well the reason I'm trying to use that slot, is because my tv doesn't have an HDR mode that can be set in its menu.

So it relys on madvr to Kick it into HDR mode. That only happens if I set it for Passthrough

I'm under the assumption that the calibration tab will allow a calibrated 10 bit signal sent to the TV ?

Because during calibration, through madtpg, the pattern kicks into hdr mode.

Whereas in the Tonemap page, the signal out is 8-bit ?


I'm trying to get, 10 bit + HDR + 3dLUT

[huhn]

hdr or no hdr has nothing to do with the sended bit deep. the properties page is the part that controls what bitdeep is send to the driver and only the driver.

the tone map HDR using external 3DLUT should trigger HDR mode because it is supposed to send HDR meta data.

so this should get you 10bit+HDR+3DLUT.

beware that sending 10 bit more often than not results in more bit deep related problem than sending 8 bit.

[etc6849]

Thanks! Will do. I have to wait until FSE breaks again though...

I did clear notifications in Windows and wonder if that fixed it. I haven't rebooted since my last post and won't without checking FSE first. Worked fine the last three times since my last post.

I'm using this mode right now, it is not triggering the HDR flag on the TV..

[huhn]

it says it it will send meta data X and doesn't so to me on the first view this is either a bug or something isn't working on your side as it should be.

try the new hard test builds i don't follow this topic and it is changing stuff all the time.

[SirSwede]

Yep, everything should look exactly the same.

Okay. Thanks.

Does the Digital Vibrance and Nuance (I have changed those values) differ between different nVidia graphics cards?

Do they differ between different nVidia graphics card drivers?

Otherwise I could just basically change out the Dimension 9150 with the GT630 GDDR5 to the Dimension E521 with the GT740 GDDR and everything would look exactly the same?

:thanks:

I don't know, all bets are off if you touch those. I would not be surprised if they worked somewhat differently with very different driver versions but they probably don't change much.

[SirSwede]

Yeah, I figured. Do you think that these values follow the drivers more than the cards?

I could just switch out the graphics cards, if you think that the GT630 drivers would work with the GT740?

That's stored on the hard drive, right? It would, thus, be possible to take the GT630 and the hard drive from the 9150 and put in the E521 and get the same picture?

Sounds like the issue I've had with one display for a long time. Your display probably adds some input lag with 24p playback. If you use the display mode switcher in MPC-HC, you can add an audio delay that only applies to 23-24 Hz.

This is how it's done in Kodi: https://forum.kodi.tv/showthread.php?tid=223175&pid=2033893#pid2033893

Hey huhn..

I tried it just now, the process hdr using external 3d lut mode is not kicking the tv into hdr, whereas the regular passthrough mode DOES kick into hdr.

Is there something fundamentally different between the mode flags ?

The Madtpg which handled the patches did itself kick the tv into HDR during calibration.. So clearly something is odd.

is the meta data different, from the two settings ?

What causes the kick .

OK, i sort of fixed it, but now (more problems).

An old issue was windows did not detect my display properly, and it wouldn't let me set WCG mode .

I had it switch back and forth, and it is now detecting my display correctly, and allowing me to enable WCG in windows settings, (which kicks the display into hdr mode.


Prior, the madvr top readout would say NV HDR, 4:2:2 10bit, limited

NOW, it says, OS HDR, 4:2:2 10bit, limited

HOWEVER, NOW, the graphics card can barely run the video even through dxva. (maybe it's taking a loop through intel gfx ?)


Before I could use error diffusion, jinc chroma, now it's barely cutting the cheese with DXVA..

Render time 36ms, 5sec max 76ms..


So, really I'm back to square 1, because I can really only play the video through NV HDR,

But, the Tone map through 3dlut function, will not kick TV into HDR mode..

Why is the tone map mode not doing this..

[huhn]

ok let's try it one more time.

there are 2 types of HDR 3D LUTs a process HDR content and a HDR SDR conversation 3D LUT. which have you created both can be loaded under HDR.

the OS HDR is not recommended and turns everything into HDR and palys around with the image.

I have created, the PROCESS HDR 3dlut from Displaycal.

It installs through displaycal window, But I've also loaded it from the folder manually..

Regardless, Using the tonemap hdr mode via 3dlut, The display does NOT kick into HDR mode, like Passthrough would..


The Madtpg DOES kick the display into HDR Mode when Displaycal triggers it for calibration/profiling.

did you try a newer madVr build one of the HDR test builds?

and this is important is the the image washed out with the HDR processing 3DLUT?

I downloaded this version of madvr last week. I didn't know there were any test builds.

The image is washed out. but the tv is NOT in hdr mode. so I thought that may have been the reason.

[madjock]

Why did I get a 4K TV :(

I am in a bit of a bind, as far as madVR goes I can get HDR, I wil play more with that later after trying different drivers, and may move up to a newer test build but have more issues than that just now.

I have an older Amp, a Yamaha RX-V377, I knew I could do 4K passthrough, so thought no more of it, got a new 4K TV yesterday and was suddenly aware of its limitations due to its age. It will only allow a max of 30mhz thru it at 4k, I struggled to understand why the TV was advertised up to 60 at 4K then read the manual for the Amp, not the end of the world I thought as I do not have the firepower in a 1050 to run 4K at 60. But for some reason the HDR signal kept on getting stuck, I could come out of a 4K movie in MPC or Kodi and the NV HDR would stay on until a reboot. Switching the Amp or the TV off had no effect.

I also noticed that madVR said the TV had no HDR capabilities when it went through the Amp, but I still could get an HDR signal with madVR, so again it was working but I kept getting stuck in a constant HDR signal once activated.

So I bypassed the Amp and went straight to the TV from my computer, this showed all the HDR options in madVR under the TV properties, and also it works as advertised, but the downside of this is I have to use HDMI ARC back to the Amp, and by doing this I lose DTS-HD and TrueHD and only get 2 channel PCM, and the majority of 4K is TrueHD so a bit of a nightmare.

The TV says to use HDMI 2/3 for UHD, yet HDMI 1 is the one with ARC, so lots of things in my way at the moment.

Computer ->AMP HDMI 1 ->AMP HDMI to TV - HDR Sticking but All sound
Computer -> TV HDMI3 - HDR Good but lose HI RES Audio using TV HDMI 1 ARC back to AMP

Can anyone think of anything I can do to stop the HDR signal getting stuck when going through my Amp ?

I think he means send video to TV and audio to receiver using two HDMI outputs on your video card.

Not an option unfortunately

DVI Output : Yes x 1 (Native) (DVI-D)
HDMI Output : Yes x 1 (Native) (HDMI 2.0b)
Display Port : Yes x 1 (DisplayPort 1.4)
HDCP Support : Yes (2.2)

Or I guess I could get cables from DVI to HDMI back to the AVR but unsure how I set up the sound seperately

[huhn]

displayport to HDMI is passive an onboard HDMI is more then enough too.

I read a couple of things saying that DVI to HDMI does not support sound ? buyt looking at the Nvidia control panel it is an option for sound.

So a DVI to HDMI cable be ok ? to send DTS-HD and TrueHD to my AVR as I can get one today. Bit of a rip off unless I get it from Amazon.

EDIT : I also remembered I have an onboard sound setup thats deactivated in the BIOS, this also has HDMI out, would I be able to do separate audio and video that way, or am I best just coming off the one nVidia card and not using the Realtek card for seperate audio ?

So... IN Tonemap via 3dlut mode..

Ctrl shift alt 3 DOES work.. left right looks different


The top says, (10bit, 4:2:2, limited) .............. (Does not say NV HDR)


Only in Passthrough mode, does it kick into (NV HDR, 10bit, 4:2:2, limited), This is the only mode which pushes tv into hdr, other than os hdr


How do I use that test madvr, it's not the standard package of files.

try version 09214

that's your intel iGPU not sure when intel added audio bitstream but it should be fine.

you have to do this:
PC -> AVR -TV
and PC -> TV

or it will not work this is far from perfect but doesn't cost you anything you need 1 more HDMI cable.

it is in theory possible to send audio over DVI HDMI adapter but this is not save thing compared to displayport.

Well I found a local computer shop that had a displayport to HDMI adapter and connected a 2nd HDMI to AVR with that. I do have the option of HI-RES sound...but

This seems to have brought its own issues, since it thinks there is a 2nd display sometimes things open up on something that does not actually exist, if I try and say just use Monitor 1, then I lose the sound, so not really getting anywhere at the moment.

Apologies Huhn, I was only trying to be thorough.. it was not intended to disrespect.

Everything seems dandy.. :thanks:


Do I have to rerun the calibration on this version, or has that stayed the same.

i don't see a reason why you would need a new calibration.

i would like you to retest this with the test build linked if that doesn't work (which you most likely test already) please make a small simplified bug report of this: http://bugs.madshi.net/my_view_page.php

my guess is the send HDR check box is just missing and madVR isn't auto detection the 3D LUT on it own to decide if HDR should be send or it is a HDR-SDr conversation 3DLUT

like i said it isn't optimal.
the non existing screen can be worked around. this is not an real deal for an experienced user and depend a lot on what you are doing on that system.

if you really want to fix this you will need a new AVR or you can try your luck with an firmware update and live with the 1.4 bandwidth limitations.

Under send the following metadata to display

How does this affect the image. Does the display arrange its whitepoint based on this sent metadata ?

And if so, if we're using the 3dlut , should we be sending the rec2020 white point or the dci-p3 white point ?

And what nit-lvl should be sent.

there is no general answer to this.

dci p3 bt 2020 and bt 709 have a white point of D65.
i don't see a reason why a display should ever change it's white point.
