madVR - high quality video renderer (GPU assisted)

[SirSwede]

Please, let me see if I have understood the function LAN Access correctly:

If the menu says "Enable LAN Access", then LAN Access is disabled?

If the menu says "Disable LAN Access", then LAN Access is enabled?

Have I understood this correctly?

Thank you in advance! :)

:thanks:

[Asmodian]

That is correct, yes.

[zeus0r]

could it simply be that HDR is invoking a different profile on your TV which is set to FULL instead of LIMITED?

you mean a different picture settings profile?! (nope, it's the same)

[MishNZ]

I use DSplayer with MadVR and I have everything set so that HDR passthrough works correctly. My display is 10bit so I use DX11 exclusive mode to get everything flowing correctly. The only downside is that with DX11 exclusive mode the audio starts and continues correctly while the video plays for a second then pauses for about five seconds then continues normally. This doesn't happen if I turn off exclusive mode. It also doesn't happen when seeking, just on initial playback. Any ideas?

Hi, this is fairly normal behaviour i'm afraid, this is unlikely to change, I get similar issues, mine plays audio for a second with a black screen, then starts after about 2-3 seconds but then plays perfectly fine. You just need to find a way to live with it mate. :)

[LigH]

I have a similar issue under Windows 7, normal 8 bit display, no HDR, even with small video dimensions and in windowed mode in MPC-HC: The video starts with several seconds blackness but plays fine if I return to the start. If you say it belongs to DX11 Exclusive mode, I will try turning it off (if it was at all enabled), but right now I am not at the PC with this problem...

[iSeries]

Another oddity for me with Win 10 (with Nvidia 1050ti). I was on 1709 and all of a sudden started getting audio drops when bitstreaming, however, other than that playback was perfect in D3D11 fullscreen windowed (neither overlay or FSE would work well). I clean installed 1803, which fixed the bitstreaming issue - however I now have a new issue (and maybe it's not an issue, I don't know). In D3D11 windowed mode playback starts out as it did before, the refresh rate jumps around a little bit, and then after some seconds it locks....but now after a minute or two, the refresh rate starts getting erratic again, jumping around, and it stays like that for the duration of playback. I am using smooth motion so no frames are reported as dropped.

But now all of a sudden FSE works perfectly - refresh rate is rock solid after a few seconds of playback. Overlay is also now usable, before I was getting frame drops every minute or so for no reason, and I tested it for 15 minutes and didn't get any frame drops, and just as FSE, refresh rate is stable.

So the issue is only with fullscreen windowed. This is with both the latest Nvidia driver and with 385.28. Focus assist / game bar and all that other nonsense is turned off. Anyone else seeing this with windowed mode, or is it just me lol.

hey there!

HDR passthrough via madvr is working fine and it puts my TV into HDR mode like it should. problem is: the picture is waaay too dark then. in dim scenes you can't even recognize faces properly.

so i tried the same files with the TV's internal mediaplayer -> perfect picture, not that dark.

any idea what could cause this?

4k SDR clips look wonderful via mpc-hc so it definitely is a HDR-specific problem.

my setup:

- philips 55pos901 oled tv
- gtx 980
- win 7
- mpc-hc + lavfilters + madvr (latest versions)
for a test
go to the nvidia control panel and change the output color format to YCbCr 4:2:2 and test again.

same dark mess... :(

i'll install win10, maybe it really is a win7 problem.

That's the image I would expect if your display didn't activate its tone mapping.

[Warner306]

How about this for a denoising filter in madVR?

NVIDIA's AI can fix bad photos by looking at other bad photos (https://www.engadget.com/2018/07/10/nvidia-ai-fix-bad-photos-deep-learning/)

Check out the video at the end. It is pretty impressive, but there is a little loss in sharpness.

It looks like that button in the movies that enhances security footage.

[nevcairiel]

Those AI algorithms from NVIDIA are all quite impressive, but way too slow for realtime video use. Its more like something for offline processing of really bad videos.

[Asmodian]

Also, in regards to CSI style effects - the AI is adding fake detail that looks correct based on many other photos, not pulling the details from the image itself. Very impressive for viewing bad photos or videos but not great for identifying someone or similar forensic applications.

[Warner306]

It could probably be taught to recognize faces. In the end, it might not be any better than manual adjustment, but in real-time. Even though it takes milliseconds to render one image, getting it to run every 16-40 ms for video would likely be impossible as nevcairiel said.

Another of example of how deep learning is coming for everyone's job. Silicon Valley is obsessed with it. They can diagnose cancer in an MRI scan in 10 seconds using current neural networks.

[zeus0r]

and what could be the reason for that? win7?

[LigH]

@Warner306: madVR is a renderer. Its purpose is to display video ... conveniently, as much as processing power permits, but most of all: fast enough. Image restoration is not its purpose, only displaying. A video filter for AviSynth or VapourSynth might be the better workflow for neural network based restoration algorithms (similar to NNEDI3). Here it appears quite off-topic to me.

Removing artifacts from video is relevant. They all have them. Neural networks are one way to do it. Neural networks can do a lot of things for video. It is up to your imagination, really.

[Warner306]

No idea. Your display must be recognizing some of the metadata because it is switching to HDR mode. It doesn't make sense why it wouldn't tone map. It must not understand the language of the PC or have something to do with Windows 7. Or not all of the metadata is making it to the TV.

Check to see if the mastering display peak nits is shown in the OSD. Also, try another file to eliminate the source as the problem.

[LigH]

Removing artifacts from video is relevant.

Then it may be a case for the decoder, because different video formats may produce different kinds of artifacts and may profit from format dependent artifact filters.

So, maybe ask for an option in LAV Filters. But I still believe that a renderer is the wrong place.

[Asmodian]

We already have a neural networks based artifact removal feature in madVR today so the idea cannot be off topic. We also don't want to deep dive into something that could never be part of madVR.

RCA is part of NGU and very effective compared to old deblocking methods, even if it is not part of the decoder.

No idea what you are talking about. For GPU processing the video renderer is the right place for sure and there are already filters to remove artifacts in madVR. So whats your point?

[veggav]

Back here to ask a few more things, since you guys have a huge patience with me :)

I use JRiver because it's the only player that can do UHD BD menus with MadVR but the latests version of JRiver still uses an old version of MadVR.
The new one has tons of goodies like denoising and some image processing that are a must.

I know what I'm going to ask is related to JRiver but if I go ask in their forums they will tell me the newer version of MadVR is not supported that's why I'm asking here.

When playing a full UHD disc the subtitles only show if the menu is showing or at least the timeline bar when you pause the movie.
When playing the M2TS file directly this doesn't happen and this problem didn't occour in the older MadVR version bundled with JRiver software.

Do you guys have any idea of something I could try here to solve the problem?


And an unrelated question, do I really have to use exclusive mode for HDR?
My monitor goes HDR mode and it seems fine in D11 Windowed (10Bits). So if it's not broken don't try to fix it? Or am I missing something?

Its a bug in the newer madVR versions, thats why JRiver Media Center still uses the old one until a release is made available that fixes it. I made madshi aware of that bug and hopefully the next one has it fixed, although he has been busy for longer then I would have hoped.

I'm not aware of a work-around.

I guess I'll let UHD BD menus aside for now since I really enjoy MadVR features in the newer versions.

This must be a really small bug because M2TS works and when you pause the subtitles are rendered so I don't think this might be hard to fix.

When you spoke with Madashi, did he mentioned a reason why this happens?

Sorry, probably should have mentioned artifact removal is already in madVR and be done with it. Typing with a morning coffee and not always paying attention.

I thought it was interesting and somewhat relevant. Nuff said..

[LigH]

That was new for me too. My personal opinion is not always right, especially with missing background knowledge... :o

[Asmodian]

I appreciated the post and link, it is cool to see what might be possible for madVR with next gen hardware. I just wanted to point out that we also shouldn't go off on a tangent about it either. It is so easy to go off topic for pages in this thread. ;)

Hi Mclingo, have you had a chance to try latest 18.7.1 ?

Not yet and reluctant to be honest, i've been having an odd problem since I tried multiple driver versions the other day, its shafted my pc a bit. I was getting a red cross on my speaker task bar icon every reboot suggesting the win audio service wasnt fully started when my PC booted, this turned out to be an issue with the win audio service not have service rights to some of the MMdevices reg keys, I think I have this fixed now but it has cropped up again randomly a couple of times now. My second issue is really odd, sometimes when I turn my TV off my PC just stop responding, nothing in events, no network nothing, its like it goes to sleep and wont wake up but the fans are still running and HDD lights are flickering like its doing something. I went back to 18.2.2 to see if this solved this, I havent tested it yet, I want to get stable again before trying this new driver.

[Siso]

I'm creating 72hz custom resolution and I was wondering which way is better - via nvidia control panel or via CRU. I'm using nvidia drivers 385.41 :)

[Asmodian]

I only use CRU as a last resort. Custom Resolutions are still a bit... unstable... and I don't think we have a good "this way works better" figured out, it seems to vary based on system and driver versions without a lot of patterns. :(

[pirlouy]

I got a new SSD recently, so I reinstalled Windows (1803) with newest nVidia drivers.
I used to use nVidia custom resolution to get perfect 23,976Hz. But now, custom resolutions don't work. Maybe that's because they improved 23,976 (still not as good as "my" 23,976), maybe it's a new bug.
In the end, I use CRU to delete some resolutions (allowing me to avoid black screen when I switch my preamp on) and no nVidia custom resolution (since it's broken) so I have a frame repeat every 11-12 minutes. I'll live with this. :/

[Manni]

Installed Build 1803 today, tried the latest nVidia drivers and still the same mess with the JVCs (video levels botched in 12bits, HDR botched in 8bits etc). Back to 385.28.

You are probably right, but I hope other users will share their experience with the custom resolutions.

[SamuriHL]

I had custom res' working but at some point in the last couple weeks after an upgrade it stopped working. I'm in the same boat with the 11-12 minute frame repeat that we get by default now. It's better than it used to be.

MadVR custom res still work fine here: 2160p@23p, one drop every hour or so using the EDID/CTA parameters of my JVC.

That's with 385.28. Last driver that works perfectly here with my JVC.

Only downside compared to the 398.xx is the 3D (1080pFP) which has a frame repeat every 3mn vs 13mn. But this improvement isn't worse all the other issues with custom res, bit depth, HDR in 8bits, levels in 12bits, etc.

Some of these issues are JVC specific, but still, too many things are broken with more recent drivers. I'm going to stick to 385.28 until a JVC owner reports that a more recent driver works perfectly. No point wasting time installing/uninstalling with each new version.

[waldnebel]

On Samsung TVs there's a special display mode to simulate HDR effects on SDR content called HDR+. It is used together with a function called optimal contrast.


Can we get such a feature for madVR? I guess those calculations done on the TVs are pretty low in quality?

Well things are about to radically change for me. Tomorrow my new lg c8 65 and pio receiver will be here so I'm moving to 4k finally. I'm actually very glad the forum is back because I'm sure I'm going to have a few questions getting everything set up properly in madvr. No more 3d to worry about for me.

You are about the fourth person who has reported issues with custom resolutions with the new driver. I tried three methods and gave up before returning to the previous working driver and applied a saved optimization from madVR. You will likely be able to apply the EDID and nothing else. Whatever new optimizations to clock timings that were made may have broken custom resolutions.

Creating HDR content requires careful grading, so I can't see real-time HDR grading as being a great idea. Colorists don't always manage to get this right with better source material and careful adjustment. I think you can get a similar effect in Windows by leaving the OS HDR switch toggled on at all times.

[Asmodian]

Custom resolutions are very strange, I just created and optimized a new custom resolution for 24Hz with madVR and Nvidia drivers 398.36. No issues at all, I have over 5h reported without frame drops or repeats.

[arrgh]

...upps... I thought this is the madVR-Forum... but obviously it is a Nvidia-forum...:eek:

[LigH]

Once upon a time, I subscribed this thread to get notified of new versions of madVR. But since I have no HDR content and no 10 bit displays, this becomes more and more irrelevant to me. And my only issue I have with madVR (several seconds of blackness at the beginning of every video) gets buried under tons of issues which don't touch me; I may even abandon it...

[JarrettH]

madshi puts out solid releases. I don't have HDR either and haven't moved from 0.92.12

Yea, it's going to be interesting and I have a whole new situation to attend to as I just upgraded from my Panasonic plasma to an LG C8 OLED. Once the receiver comes tomorrow I will start working on getting madvr configured for 4K HDR with my nVidia 1060. I'm sure this will be just delightful fun trying to get everything working smooth. LOL Now that I'm on 4K I may opt for a 11 series nVidia card when they come out. I'm sure getting 4K smooth on my 1060 is going to be a bit challenging but we'll see.

Stupid question time. How do you get the 24Hz custom res to stick the 23.976Hz timing? I tried this and when madvr switched to the 24Hz res, it literally showed 24.000.
