madVR - high quality video renderer (GPU assisted)

[madshi]

Here's a quick fix for the crash problem:

http://madshi.net/madVR925b.zip

New official v0.92.6 with this fix (and maybe some more changes) will come tomorrow.

Who's going to be the first madman to remove random noise and then add grain?

[madshi]

Who's going to be the first madman to remove random noise and then add grain?
It's actually not as mad as it might seem because:

1) encoded grain is often quite artifacty.
2) upscaled grain looks bad.
3) added grain after upscaling has no artifacts and looks high-res.

However, removing grain may also remove details. So it's probably still not a good idea overall.

[Ver Greeneyes]

Can you make a sample available, or 2 or 3 which show this problem? Would be interesting to look at them.
Sure, here's a 30 second clip from the start of an old Let's Play: https://mega.nz/#!SBlwlZ5K!msF_yjXZZASnnxpv8-nTjaRXQEkbCEN_iAvkBN7KBCU (pretty much just the menu screen, here's (https://www.youtube.com/playlist?list=PL06A8EF9E4353DC85) the full playlist)

In general I've noticed that the chroma channel for Youtube videos tends to be pretty horrendous (including for higher resolution videos), I don't know if that's just the bitrate or if Youtube's re-encoding makes it worse.

[huhn]

how do you change stairs on an image. ping
thank you

sorry i can't really follow you. if you are talking about aliasing billinear adds a lot of aliasing.

@deblocking

my first issue with the deblocking is that it very fast changes images parts that are not blocky anymore and makes them very unsharp but on other images parts the blocking is still there.

i used a very blocky video file from on old computer game using SMK2 as a codec.
here an image: https://abload.de/img/winordert5uc3.png

and i wonder if debanding is run before or after deblocking.

[mzso]

Is there an easy way for me to reproduce this without requiring any actual DVB hardware?

I don't know. I don't think progDVB loads anything if you don't have tuner running, with a channel tuned. (And so far I haven't heard of a dummy tuner.)


Trying with the hotfix I could still get Potplayer hanged video open spamming.
But I noticed that the madVR OSD is still updating. Does that mean anything? (I didn't think to have OSD open before, so I didn't know how it was.)

Link: https://drive.google.com/open?id=0ByfdfPvnoDuzUGx6d0ZfU3E1Mnc


I also noticed that madVR shows DXVA, even though I disabled HW accelerated decoding in LAV. Is that normal because of deinterlacing?

sorry i can't really follow you. if you are talking about aliasing billinear adds a lot of aliasing.




excuse me, how did you change BILINEAR to NGU on a single image. png?

[huhn]

madVR is by default using DXVA chroma scaling when DXVA deinterlancing is used you can control this under trade quality for performance.

[huhn]

excuse me, how did you change BILINEAR to NGU on a single image. png?

i pause the video and change the scaling algorithm.

[dvd1]

[QUOTE=huhn;1821256]i pause the video and change the scaling algorithm.[/QUOTE
]then if I pause is changing the scaler already changes or should I start the video again?
thank you so much

[huhn]

you don't need to start the video.

MPC-BE (1.5.1 (build 2755) beta) crashes with madVR turned on. If I try to change file after playing it or if I try to close player, then crashes. With previous version, this didn't happen.

However, there is no problem with MPC-HC (1.7.13).

madshi, I have the exact same issue. My crash in MPC-BE (1.5.1 build 2755) crashes when I try to exit MPC-BE. That is with your new features turned on or off.
Beyond that, the "reduced random noise" and reduce compression artifacts" do wonders for some of my noisier 480p content. :thanks:

[huhn]

https://forum.doom9.org/showpost.php?p=1821246&postcount=46369

this may fix your crash issue.

[AngelGraves13]

Hmmm...not sure how I feel about the new compression removal. If I'm watching something with lots of grain it seems to target the grain and make the image appear processed. It's a double edged sword.

I guess it's mostly for DVD sources, as it's not really needed for blu-ray or 4K.

[cyberscott]

https://forum.doom9.org/showpost.php?p=1821246&postcount=46369

Thanks! That has fixed the crash issue for me. Somehow, I read right past madshi's fix.

[Anima123]

Madshi,

After upgrading to 0.92.5, mpc-hc will crash if drag another video file to the player. It never happened before.

BTW, the crash will occur with or without the new reduce compression artifacts options.

Edit: I should have read the new posts before posting. The hot-fix version fixed the crash problem for me.

Edit2: 'automatically detect hard coded black bars' seems to cease to working with the 'reduce compression artifacts' on.

[SamuriHL]

1) Please test the new algorithms and let me know what you think!


Um, they ROCK, that's what I think! Upscaling my goto test DVD looks like a freaking blu-ray. I'll be able to test the block algorithm on some of my cable recordings. The idiots are using heavily compressed h.264 with some of the worst settings I've ever seen.



7) Please compare the new AdaptiveSharpen version (it's igv's variant) to the original AdaptiveSharpen algorithm. On a quick check I liked igv's variant better, but I'd like your feedback on that.

I'm not typically a fan of the sharpening options, however, this seems to work really well. I haven't used the old variant so I can't compare the two, but, this may get me to change my mind about keeping it enabled.

All in all, seriously awesome job!

[SamuriHL]

Just noticed a crash problem in v0.92.5, which happens when switching from one video file to another, or sometimes even just closing a video file. Already found the cause of the problem, stupid bug. Sorry, my bad, will fix that tomorrow in v0.92.6.

Aha! Ok, good. I just ran into it closing my file and JRiver MC completely crashed so at least I know why. Thanks!

EDIT: Obviously have now seen the 0.92.5b fix and can confirm it does fix it. Awesome!

[SamuriHL]

Wow if you really want to see what those options in madVR can really do, grab a copy of Remo Williams The Adventure Begins on DVD. Mine is the crappy 4:3 release and the detail is just incredible. That is a HORRIBLY bad release so the fact that there's now clear details upscaled to 1080p is freaking incredible.

[Magik Mark]

Which among the chroma upscalers works best with "artifacts cleaning" algorithms?

I'm using NGU standard low, med & high. I'm getting a lot of dropped frames. I have GTX 960

[ABDO]

no way "reduce compression artifacts" and "reduced random noise" make impossible result on 576 2d Anime

with long time and alot of traying difrrent denoise filters (QTGMC, hqdn3d, eDeen, FluxSmooth, TemporalCleaner, Deen, dfttest,DeGrainMedian, RemoveGrain, gradual denoise, mplayer temporal noise reducer, denoise 3d) and i tray many noise reduction highend plugins ( topaz denoise, MSU Denoiser, Neat Video, Denoiser II, Red Gian denoiser ) and also i tray many programs ( CyberLink PowerDVD Ultra, corel windvd ) every one from this has big Common defect, in low strength settings it destroy the images, While keep alot of noise and artifacts,The higher strength settings totally destroy the images and blured it much.

only waifu2x do great job, in 2d Anime it can tottly clean the noise and compresing artifacts, While keep the images sharp and crisp, put to do that it take very long time (4 second for every frame )

now madvr do it again and offer the best solution ever, the new algorithm in strength settings (3 : 8) do Almost the The same efficiency Like waifu2x, it tottly clean compression artifacts and noise, While keep the images sharp, crisp and never blured or destroyed lines or details.

With observation, that madvr algorithm do that in realtime, it much much faster than waifu2x and alot of highend noise reduction plugins.

K

[ryrynz]

Some NGU sharp here a touch of reduce compression artifcats there and a sprinkle of Adaptive Sharpen and 720 never looked so good.
That exciting time when you have to revisit your profiles..

RCA at 1 works well, I wouldn't mind a setting or two below it though.

[chros]

The problem only goes away when I untick HEVC in LAV video configuration. Then the playback is smooth and nothing happens.

It's safe to say that the problem is causing because of my not HEVC compatible video card, the GTX 650 Ti.
Actually it is. :) But only with <=1080p, 8bit hevc! (So not with 4k hevc, neither with 10bit 1080p hevc.)
It's based on Kepler architecture, as my laptop card (see my signature, along with the driver version I use), and it works the same way for me as well.

1) VSFilter does its thing before madVR is involved, so the subtitle placement it totally out of madVR's control.
2) I think MPC-BE's ISR doesn't fully support madVR's subtitle positioning options. You *may* have more luck with MPC-HC's ISR. IIRC kasper93 had invested some time to make it work. But I'm not sure how well it's working.
It also works (https://forum.doom9.org/showthread.php?p=1819937#post1819937) with MPC-BE's ISR.

[Razoola]

I have the same issue with 092.5 crashing bringing MPC-HC from fullscreen on secondary monitor to windowed on primary monitor. Going back to 092.4 fixed the issue.

update, 092.5b fixed the issue.

[d3rd3vil]

Is there absolutely no way atm to display Dolby Vision content via PC (MPC-MadVR) to a Dolby vision tv? No support whatsoever?

Its a damn shame. HDR10 works

[nevcairiel]

Dolby isn't exactly open and forthcoming how their stuff should work, you know.

[d3rd3vil]

Isnt there a way to just forward the metafiles so the TV can handle it or sth.? And what if you have a file with HDR10 AND DV, is there a way to deactivate the HDR10 somehow so the TV only uses the DV layer? Just as a secondary question if you dont mind ^^

[Drakko01]

Hi Madshi, what upscalling option do you think is better for me , I playing bluray / 1080p high bitrate videos on a 4k tv lg uf8500, mpc-be ,lav filters 0.72.77 along with SvP to do 60fps, my hardware is a I7 3770k, Gtx 1070, 8gb of ram.:thanks:

[cork_OS]

Quick thoughts about new madVR algorithms:
1) On my samples RRN often smooths severe blocking more effectively than same strength RCA.
2) GTX1060 3Gb is on the limit for 1080p60 RCA/RRN processing, I have to overclock it to minimise dropped frames.
3) RCA with strength=4..6 is very effective for reducing mosquito noise on H.264 HD videos with a lack of bitrate (like game recordings from YouTube/Twitch), sharpness loss is slight.
4) RCA with strength=1..3 is effective for reducing slight/moderate compression artifacts on various H.263/MPEG-4 ASP (XviD etc.) non-cartoon SD encodings, detail loss is visible but acceptable.
5) Unfortunately RCA/RNN is in general detail destructive for non-cartoon SD video, however other denoising filters may be even more destructive.

EDIT: Conclusion: great work, as usual!

[XinHong]

@Madshi: Do you have any ETA for D3D11 with DXVA scaling ?

[Telion]

Thanks. It's good that you did 6 of them, because only the 6th contained somewhat useful information... :D
Please let me know if v0.92.5 fixes the issue (when it's released, don't know yet when that will be).

Unfortunately, that didn't fix the issue for me.

[mrmarioman]

Using latest madvr and nvidia drivers. Now Windows will automatically turn on its hdr if I play a movie with madvr. I have it set to 'off' because I'm using a 980Ti. But no matter what setting I try (let madvr decide or passthrough hdr) Windows will automatically turn on its hdr.

[Sarlaith]

Hi Madshi,

You appear to have introduced a new "bug"
When optiming custom resolutions;
When you press "Test Mode", it tests the new custom resolution.
But "Stop Timer" doesn't restore the previous mode, only "No" does.

When pressing "Yes" (to save the custom mode) it say's you can't save the active mode

[hubblec4]

Hi madshi

with the new version my mpc-hc crashes every time when I close it. I have no settings changed. All fine with v0.92.4

[huhn]

[arrgh]

...Sadly, 3D playback requires D3D11 <sigh>.
...
Did you already upload freeze reports for this? I don't recall right now.


but : why does the studdering only happen if I actually activate D3D11; if I deactivate it than I still get 3D but without studdering?

yes, I did post freeze reports, but you came to the conclusion that madVR is mostly gone already and you can not pinpoint a reason, why MPC-BE should hang.

[madshi]

Sure, here's a 30 second clip from the start of an old Let's Play: https://mega.nz/#!SBlwlZ5K!msF_yjXZZASnnxpv8-nTjaRXQEkbCEN_iAvkBN7KBCU (pretty much just the menu screen, here's (https://www.youtube.com/playlist?list=PL06A8EF9E4353DC85) the full playlist)

In general I've noticed that the chroma channel for Youtube videos tends to be pretty horrendous (including for higher resolution videos), I don't know if that's just the bitrate or if Youtube's re-encoding makes it worse.
Hmmmm... The next build will now process chroma in its original resolution, which should speed things up, and may also improve quality a bit. If you still think you need different luma vs chroma strengths, you can now use the file tags (e.g. "deblock=4 deblockChroma=8"). The settings dialog doesn't support this atm, though.

Trying with the hotfix I could still get Potplayer hanged video open spamming.
But I noticed that the madVR OSD is still updating. Does that mean anything? (I didn't think to have OSD open before, so I didn't know how it was.)

Hmmmm, that's bad. Can you create a debug log from this situation for me?

@deblocking

my first issue with the deblocking is that it very fast changes images parts that are not blocky anymore and makes them very unsharp but on other images parts the blocking is still there.

i used a very blocky video file from on old computer game using SMK2 as a codec.
here an image: https://abload.de/img/winordert5uc3.png
Hmmmm, yes, it doesn't work well with this image at all. Never heard of SMK2 codec yet. FWIW, the algorithm is optimized for MPEG1/MPEG2 style compression artifacts, which look rather different to what SMK2 seemingly looks like. With MPEG1/MPEG2, if you have blocks anywhere near this strong, the rest of the image is a big mess, also, so it needs a lot of smoothing to be even remotely acceptable. With SMK2 it seems to be different: The blocks are bad, but where there are no blocks, the rest of the image still looks decent. That's not a situation my algorithm can handle (well). But it's also not a situation that you'll typically see with MPEG2, VC-1 or h264 videos.

and i wonder if debanding is run before or after deblocking.
Compression artifact reduction is run first, debanding afterwards.

Hmmm...not sure how I feel about the new compression removal. If I'm watching something with lots of grain it seems to target the grain and make the image appear processed. It's a double edged sword.

I guess it's mostly for DVD sources, as it's not really needed for blu-ray or 4K.
I agree that for high-quality sources it's probably not useful. Except maybe if you absolutely hate grain.

Edit2: 'automatically detect hard coded black bars' seems to cease to working with the 'reduce compression artifacts' on.
Seems to work fine for me?

Some NGU sharp here a touch of reduce compression artifcats there and a sprinkle of Adaptive Sharpen and 720 never looked so good.
That exciting time when you have to revisit your profiles..
Have you had a chance to compare the new Adaptive Sharpen to the old one? Would like your feedback on that, if you find some time to compare.

RCA at 1 works well, I wouldn't mind a setting or two below it though.
Ok, I'll try to add a lower setting.

Is there absolutely no way atm to display Dolby Vision content via PC (MPC-MadVR) to a Dolby vision tv? No support whatsoever?

Its a damn shame. HDR10 works
Dolby Vision UHD Blu-Rays have a HDR10 base layer, so you don't lose all that much. What you do lose is 12bit support and dynamic metadata support. Dolby Vision is a very complicated thing, I'm not sure if I'll support it. Maybe, maybe not.

Hi Madshi, what upscalling option do you think is better for me , I playing bluray / 1080p high bitrate videos on a 4k tv lg uf8500, mpc-be ,lav filters 0.72.77 along with SvP to do 60fps, my hardware is a I7 3770k, Gtx 1070, 8gb of ram.:thanks:
I don't know how much performance SVP costs, so it's hard for me to do a specific recommendation. With high-quality content usually NGU-Sharp or NGU-Standard looks pretty good for image upscaling. That's the most important setting to choose. The chroma options are much less important in comparison.

Quick thoughts about new madVR algorithms:
1) On my samples RRN often smooths severe blocking more effectively than same strength RCA.
2) GTX1060 3Gb is on the limit for 1080p60 RCA/RRN processing, I have to overclock it to minimise dropped frames.

EDIT: Conclusion: great work, as usual!
Interesting, I didn't expect "RRN" to handle blocking better than "RCA"! So is there anything RCA does better than RRN for your use case?

FWIW, there's minor blocking and there's major blocking. For minor blocking, RRN might work well, but I think it will be out of its depth with major blocking.

@Madshi: Do you have any ETA for D3D11 with DXVA scaling ?
Sorry, I usually don't give out ETAs.

Using latest madvr and nvidia drivers. Now Windows will automatically turn on its hdr if I play a movie with madvr. I have set to 'off' because I'm using a 980Ti. But no matter what setting I try (let madvr decide or passthrough hdr) Windows will automatically turn on its hdr.
What does "Windows will automatically turn on its hdr" mean exactly? Does a window popup which says "hello, I'm Windows and I've just turned on hdr"? Or what happens exactly that makes you say that Windows turns on hdr?

the "reduced random noise" and reduce compression artifacts" do wonders for some of my noisier 480p content.
Wow if you really want to see what those options in madVR can really do, grab a copy of Remo Williams The Adventure Begins on DVD. Mine is the crappy 4:3 release and the detail is just incredible.

Sounds great! Maybe you could post 2-3 "before vs after" screenshots which showcase the improvement you're seeing?

You appear to have introduced a new "bug"

When you press "Test Mode", it tests the new custom resolution.
But "Stop Timer" doesn't restore the previous mode, only "No" does.

When pressing "Yes" (to save the custom mode) it say's you can't save the active mode
I think the behaviour is as intended. You press "Stop Timer" if you're not sure yet if the new mode is "good" or not. So the previous mode should not be restored yet if you press "Stop Timer", because that gives you more time to test the mode. When you press "No", or if the timer runs out without being stopped, or if you press Escape, the old mode is restored. If you successfully press "Yes" to save the mode, it actually stays active.

If the GPU driver refuses to save the mode that's a bug in the Nvidia GPU driver, unfortunately. It happens for me, too. Nvidia is aware of this bug and will hopefully fix it some time in the future.

Unfortunately, that didn't fix the issue for me.
Argh, that's too bad... :( In that case, can you create some more freeze reports for me? This time it would help if you did this with the proper media player PDB debug symbols and LAV Video Decoder PDB debug symbols in the right folder. That way the freeze reports will also tell us what the media player and LAV were doing. Maybe that helps figuring out what's going on?

You double click "activate debug mode.bat", then you reproduce the problem, then you double click "activate release mode.bat". Done. Now you should have a monster sized debug log on your desktop. Zip it up and upload it somewhere, don't attach it to this forum.

madVR v0.92.6 released

http://madshi.net/madVR.zip

* fixed crash introduced in v0.92.5
* algos "reduce compression artifacts + random noise" now faster for chroma
* added "deblockChroma" and "denoiseChroma" file tags

What does "Windows will automatically turn on its hdr" mean exactly? Does a window popup which says "hello, I'm Windows and I've just turned on hdr"? Or what happens exactly that makes you say that Windows turns on hdr


Well, you know, Windows has a toggle to turn on hdr. I always have that off. I use nvidia. But now when I play a movie, Windows will turn on that setting -if I go to the menu I can see it's on. And the colours when I stop playing a movie will wash out: I have to go to the menu and turn off hdr everytime I stop playing a film. It starts on its own.
This is also causes the screen to sometimes not display hdr colours correctly. Sometimes it works, sometimes it looks washed out.

Do you mean the toggle "HDR and Advanced Color"? I've never heard yet of this toggle automatically enabling itself! Are you on some fast track Windows 10 beta build, maybe?

Sounds great! Maybe you could post 2-3 "before vs after" screenshots which showcase the improvement you're seeing?


Yea, I'll try to get to it in the next couple days when I get a free minute. The source material that is my goto testing for these kinds of improvements is the Highlander Endgame DVD upscaled to 1080p. I threw in Remo Williams just to see cause I know how bad that DVD is mastered and that really surprised me. I'll see what I can do for screenshots soon.

I'm really glad to see you've created a RCA and a RRN, I can finally get rid off ffdsohw... Well not yet.

First, I want to precise I'm not a huge fan of processing filters. But some DVDs are so noisy... It's almost unwatchable on a large 4K screen. So in that case, I'm willing to sacrifice some little details if the whole picture seems better.

RCA is great! It does a wonderful job at reducing the compression artifacts while preserving a very good level of details. It's very good for DVDs, I'm using strength 2. But even at 1, the difference is easily visible. I thing the highest values are useless, I would prefer one level below level 1 to fine tuning some videos.

RRN was one of the algos I was waiting for the most. For now, I'm a little disappointed with this one. Ok it does a very good job at denoising the picture but the cost in details and sharpness are way too high for me even at strength 1. Maybe is it just a matter of strength? Could you create a strength some levels below 1? For now, I prefer TTempSmooth. It's a good denoiser, it doesn't clear all the noise but it stabilize it while preserving most of the details. But I would prefer to use only MadVR because ffdshow is quite buggy!

Anyway, thanks a lot for all your work. I hope you can improve RRN in a future build but you definitely made MadVR more incredible once more :)

At least they compress extremely well. I made two:

PS:
You didn't say anything else about the process I should follow so I activated debug mode, started Potplayer, produced the hang, killed off potplayer, then deactivated debug mode.

TTempSmooth is a multi-frame algorithm, while RRN is a single-frame algorithm. Generally, multi-frame algorithms have an advantage for random noise (and grain) removal, because random noise and grain are (supposed to be) different in each frame while the actual image content stays more or less static (unless there's motion in the scene). If you want to compare RRN with other algorithms, please pick single-frame algorithms for comparison purposes. I do plan to look into multi-frame algorithms in the future, but it's not too easy. For best results you basically need some sort of motion compensation, or at least motion detection. And if that compensation or detection goes wrong, you can end up with pretty bad artifacts. For now I wanted to start with a single-frame noise reduction algorithm, because it's easier to implement and less dangerous in terms of adding weird artifacts.

Hi madshi,

Wont quote the entire post.
This error is the new error when you can't save because the NVIDIA driver bugged up? doesn't look like the/a GPU/driver error.
http://www.image-share.com/upload/3639/5m.jpg (http://www.image-share.com/ijpg-3639-5.html)

After clicking "Ok" it reverts back to the previous resolution

Edit:
If I stop the timer, change the resolution in the NVIDIA control panel I get a very different message. (logical probably because I change resolutions in between)

Edit 2:
It just appears to be still in "test mode" in the NVIDIA API and thus not allowing to save it

Edit 3:
Checked with MadVR 0.9.2.0.3, it is 99% sure a MadVR bug.
On that version I can set pretty much any resolution and it will save it. Going back to 9.2.0.6 gives me the same behavior/error again.
So can you please fix that? ;)
Looks to not exit/still be in "test mode" when you click save, thus giving the error it cannot save the active mode.

Hmmmm... The next build will now process chroma in its original resolution, which should speed things up, and may also improve quality a bit. If you still think you need different luma vs chroma strengths, you can now use the file tags (e.g. "deblock=4 deblockChroma=8"). The settings dialog doesn't support this atm, though.
Thanks! I'll play with the tags and see if I think diverging settings are worthwhile.
