madVR - high quality video renderer (GPU assisted)

[ryrynz]

Could it be anything to do with my 144hz 1440p display?

Nope. Reset madVr to default settings via the batch file in the directory.

[DragonQ]

Should be fine. Do you watch any interlaced content? This should be rare in this day in age. Maybe a network TV show?
In the UK all HD broadcasts are 1080i/25 or 1080p/25. UHD can't come soon enough.

[aufkrawall]

No problems to report so far with a GTX 1070.
If you're using DX11 FSE, be sure that the "present a frame for every vsync" is checked with a Nvidia GPU, else there is stutterring which isn't recognized by madVR's stats.
It would probably be best if this option couldn't even get unchecked with Nvidia GPU, it provokes wrong configuration by the user.

[Warner306]

Well something strange happened today....
I turned everything off on that de-interlacing page and everything runs very smooth, actually VERY Smooth without any gitter....

Plus the section marked dropping frames or adding frames - within a minute or two gets to numbers I've never seen, e.g. NO dropped frames and No repeated frames, that's never happened before while running everything on 60Hz.

Usually I see repeating or deleting frames happening all the time. Now it starts off as say 1 dropped frame every 1.5 hrs, within seconds 2.5hrs, after running a BD for say 2mins its up to 1 dropped frame every 9.10hrs, then say running for 5 mins its up to 1 dropped frame every 3 days, then onto no dropped or repeated frames... This has to be a really good thing surely?

I have never ever seen numbers like this on any material with de-interlacing and film mode ticked. Its usually repating frames every few secs all the time, this might be since I run on 60Hz.

I get no dropped frames or presentation glitches.

Rendering is round 15/16.50ms average on Nnedi3 32 with video card 1080

I don't know why things would improve. A source needs to be recognized as interlaced to use those options.

Well every file that 29.??fps that's goes through with de-interlaced and film mode ticked always shows up as being de-interlaced, ON.

Also with only de-interlacing ticked, all 29.?? fps files end up with de-interlacing ON.

When I don't have any ticked 29.??fps files get played without de-interlacing on, why is that?

Remember I play everything at 60Hz.

Without deinterlacing ticked, the file is not deinterlaced. That makes sense because that is what you are telling it to do.

Doesn't the interlaced file have combing artifacts when it is not deinterlaced? It has to be deinterlaced at some point.

The source fps has nothing to do with it being interlaced.

Quote:

Signal Type: The method of displaying an image. Interlaced sources store images as odd and even horizontal lines or fields. The display draws the odd lines in one pass and then the even. Progressive images are shown in a single pass, where every line is drawn in succession. Interlacing was originally designed for cathode ray tube (CRT) displays.

Interlacing is still used today in some TV broadcasts to reduce bandwidth when broadcasting remotely. Interlaced sources must be deinterlaced to be shown on progressive scan displays. Progressive signals require more bandwidth but produce fewer artifacts and offer higher vertical resolution. Progressive signals also remove the need to deinterlace.

No they are all as clean as a whistle, NO combing so why are the 30fps files being deinterlaced which its ticked if they don't need it. They play way smoother too when its not ticked.

Everything that's 30fps ends up getting deinterlaced when that box is ticked, that doesn't seem right to me...

So what does it all mean???

[bcec]

MadVR is no longer enabling 3D Stereo in the OS automatically after Win 10 Anniversary Update for me. Resolution automatically switches to 1080 (from my 4k default), however 3D in the OS is not enabled, so video is shown 2D only. To fix, I have to manually go into nVidia settings and enable Stereoscopic 3D myself every time.

@madshi, is this a known issue? (Win10+anniversary_update+nvidia+madvr v0.90.24)

I have got the exact same issue as it seems ... i am struggling with this since almost one week.

I can activate the stereo setting in the nvidia panel (windows 3D switch is enabled automatically) and playing a 3D file will work fine.
But as soon as a 2D file is played... the setting in the nvidia panel is unticked while the windows setting stays at on. Afterwards i am no more able to play a 3D file in 3D until i tick the nvidia setting again manually.

I am using the following setup:

WIN 10 Pro 64bit - No anniversary update yet
GTX 1080 - latest driver
MPC-HC
Madvr - latest version

I had it working a few weeks ago using the same settings within madvr as today.

So i guess this might not be only related to the anniversary update as i don`t have it yet...

do you have a sample and did you changed anything in lav filter?

I cant touch anything in lav filters as I use JR, its all set up in there...

[huhn]

what happens with mpc-hc?

[70MM]

what happens with mpc-hc? Ive never used that player and not set up for it.

[huhn]

the only things that needs to be change is the video renderer to madVR that's it.

sorry i don't know if your splitter/decoder is setup in a way to flag everything as interlanced or if the file is indeed interlanced or not without a sample and without known settings.

most TV streams with "30 FPS" are interlanced. and there is no spec for 1080p30 on the blu ray only interlanced.

You should always leave deinterlacing on as madVR will do the best job. Any proported performance improvement is probably in your head. This is especially true if rendering times are fine.

If a source that is not interlaced is being deinterlaced, that is a whole other problem. You may have to post a sample if that is the case. You are sure deinterlacing is shown in madVR's rendering stats?

[AngelGraves13]

I just set deinterlacing mode in LAV Video decoder to "aggressive" so that it flags every frame in an interlaced stream as interlaced, otherwise it'll randomly turn itself on/off throughout the stream.

[qjb2016]

I found that, for the video source such as concert, in the madVR off the anti cross function, the screen rendering time will be doubled, reaching 33.17ms, which will reduce the Drop frame and jitter.
I use Dmitrirender to do frame interpolation
I use DSplayer KODI

[roninf]

Can someone let me know how Madvr is triggering a display/ GPU to enable 3D/stereooscopic mode when a 3D file is played? How does it interact with the settings in the nvidia control panel for example ?
And as there is an option to passthrough HDR untouched to the display ... has someone got this working or is passing the metadata for the TV to enter HDR mode not working/implemented yet?

[sneaker_ger]

Passing through HDR metadata is not implemented. Only Nvidia has an API for it(*) and madshi said he doesn't like it and he'll be waiting for a better one.

*(AMD released a new media SDK (https://community.amd.com/community/gaming/blog/2016/08/16/high-quality-advanced-media-framework-streaming-and-recording-api-now-open-sourced) a few days ago. Don't know if it brings HDR. Maybe needs a new driver, not new SDK...)

Perfect thanks very much for the info! :)

[Stereodude]

Those of you that use a GTX 1080 card for MadVr, what settings can you use for 720p and 1080p, 24 fps content?
That's a very vague question. Outputting what resolution? 1080p, UHD?

[Stereodude]

So, has anyone else found scenarios where there are no apparent settings in madVR for what it does or that madVR does things that aren't per the settings?

For example, if I play back UHD content to my 1080p TV I get no chroma scaling, and I get luma downscaling based on my settings. Great, that's as expected. But, if I playback the same UHD content in a window, I get luma downscaling and chroma downscaling. The luma downscaling is per my settings, but it says in the OSD that it uses Bicubic75 AR for chroma downscaling. I can't figure out where that Bicubic75 AR is set. I don't have Bicubic75 AR set as a scaling algorithm anywhere in my madVR settings.

I tried playing with the settings a bit to figure out what's going on. It seems madVR will use the same algorithm for Chroma downscaling as is set for chroma upscaling for most of the algorithm options. However, if you choose Jinc, Bilateral, Super-xbr, or NNEDI3 as the chroma upscaling algorithm you get Bicubic 75 (AR) chroma downscaling. You may or may not get AR. If you pick Jinc as the upscaling option the AR checkbox also affects whether you get AR on your Bicubic75 chroma downscaling. For Bilateral, super-xbr, and NNEDI3 you get AR with your Bicubic 75 chroma downscaling automatically. Now I get that NNEDI3 can't downscale (super-xbr too?), I guess there's also no chroma downscaling pixel shader code for Jinc or Bilateral so it defaults to Bicubic75 (AR) for these options.

I guess all this to say it seems there should be a separate chroma downloading section, or it should follow image downscaling (if possible), not the chroma upscaling section?

Along the same lines, are the OSD settings displayed in madVR absolutely a correct representation of what the underlying engine is doing? IE: If the OSD says it's using Jinc AR is it absolutely using Jinc AR with no possibility that the OSD is incorrect about what the scaling engine is doing? I've found a few other scenarios similar to the one I've mentioned above where the OSD displays scaling settings that are seemingly at odds with the settings in profiles.

[huhn]

disable scale chroma separately, if it saves performance so you are only using image scaling when downscaling as it was in the past the rest is just a save performance for speed trade of nothing else.
image doubling algorithm can't down scale same for specialized chroma scaler.

the OSD informations are supposed to be correct.

Ok i think i found the solution for this issue even though i am not happy with it :(

So here is what i did:


set 2D 1080p as resolution in the nvidia panel
setup stereo in nvidia panel with the wizzard
madvr settings as before 3d enabled all the standard settings for 3D
rebooted
checked settings again
played a 2D file (which always broke 3D for me)
played a 3D file and it was working
repeated several times and it was still working


So this is not really what i wanted to find out because i definetly want to use 4K as standard resolution....:(

Btw. you can still have files scaled up to native 4K resolution in adding the display modes to madvr mode switcher - i checked this as well.
Somehow this whole thing does not make sense to me.
Can someone else maybe verify this as well and tell me if that makes sense or not?

Still i don`t know if madvr or nvidia is the underlying issue here... i guess its nvidia more likely...

[x7007]

Does anyone know why when I use Exclusive mode D3D11 + Potplayer x64. Entering FSE causing a delay because I am using 60 Hz on the desktop and somehow potplayer or madvr think the MKV movies is FSE 59 Hz, so it is switching to 59 Hz when FSE which causing the black screen delay. It is causing issue in TeamViewer for example when I want to watch something and I only see black screen all the time till I got out of FSE. when I'm sitting on the computer there is terrible annoying delay because of HZ switching. using 59 Hz and not 60 Hz from the Display settings does not have the Black Screen anymore, it is instant. Do anyone know the fix for that ? somehow I fixed it before but new drivers released and I checked now when watching a movie and it's back.


Windows 10 x64
Potplayer x64
Madvr 0.90.24
Lavfilters 0.81

Yeah you are right. 1080p output

[chros]

I've tried out but I'm not sure whether I saw any stuttering without it (see my config in my signature). Indeed, there's nothing in stats.
Do you use display refresh changer (I do) and Smooth Motion (I don't)?
I'll try to look at it "closer".

[Stereodude]

Yeah you are right. 1080p output
I have my boost clock set to 1850MHz. I use 12-bit 1080p output in the Nvidia control panel. madVR is set to DX11 10-bit FSE output. I'm not using ED. Most of the performance for quality options are not checked.

I use NNEDI3 128 Luma doubling and NNEDI3 32 chroma doubling with SSIM2D 50 AR/AB luma downscaling and Super-xbr chroma upscaling on 720p24 content and get a render time in the low 20ms time with some light enhancements (SR2, sharpening etc.).

For 1080p24 I use super-xbr supersampling for luma with SSIM2D 50 AR/AB luma downscaling, super-xbr on Chroma and get a render time around 35ms with some light enhancements (SR2, sharpening etc.).

[aufkrawall]

Do you use display refresh changer (I do) and Smooth Motion (I don't)?

Yes, i'm using SM (saw it with a 60fps video at 75Hz). I didn't check if it was related to it (might be possible).
Performance savings by that option unchecked shouldn't be very big anyway, probably hardly existent for a fast GPU.

These are the settings I am using at the moment with my GTX 1080 card. I'm still looking to improve IQ more, as I suspect Jinc AR for Chroma doubling/quad is making the image less sharp.

Thoughts anyone?

I think you should just use a sharpener if it's sharpness you're after.

[Betroz]

I could, but adding more and more filters can add more artifacs to the image, and that is something I don't want.

[ryrynz]

I could, but adding more and more filters can add more artifacs to the image, and that is something I don't want.

Just enable stuff and go with what you like. More sharpness does not necessarily equal better image quality. I think personally I'd prefer a less sharp resizer and use the image enhancements.

[Betroz]

Having NNEDI3 for double/quad Luma, and Jinc AR for only the double/quad chroma layer, is that somehow a bad solution or just a matter of personal taste for IQ?

[YxP]

I could, but adding more and more filters can add more artifacs to the image, and that is something I don't want.

You are already doubling and downscaling an image a lot that could easily just be upscaled and sharpened. If it's a kind of pipeline purity you're after, I'm not sure that's the best way to do it. Madshi's sharpeners are also pretty damn good, I wouldn't be too hasty worrying about possible artifacts.

Yes but when you use image doubling with a 720p source and have a 1080p output, it is first upscaled to 1440p, then down to 1080p. For 480p that would be another step (quad) extra. Are you saying this is pushing more pixels than nessesary? Just jusing Jinc for all upscaling is not as sharp as NNEDI3 as you know.

With my old GTX 970 card I used NNEDI3 128 for Chroma Upscaling and Super-xbr antibloat 25 for all my image upscaling needs. Worked fine, but GTX 1080 is a faster card, so now I need to find a combination that give me a better image than before. I wish I could just use NNEDI3 256 neurons on everything with no dropped frames :D Or 128 neurons for that matter, but the GTX 1080 is simply not powerful enough. Even 64 neurons is pushing the rendertime way close to 40ms...

Personally I wouldn't double a 720p picture for a 1080p screen. Your mileage may vary :) I'd go with jinc+SR2 or SR3. Plenty sharp for my taste even without added sharpening. I also think finding the perfect sharpener settings and combos would be more bang for the buck so to say.

[Stereodude]

With my old GTX 970 card I used NNEDI3 128 for Chroma Upscaling and Super-xbr antibloat 25 for all my image upscaling needs.
Why are you using higher quality NNEDI3 settings for Chroma than Luma? I'd be quite skeptical if there's any benefit going beyond 32 for Chroma.

[Betroz]

Why are you using higher quality NNEDI3 settings for Chroma than Luma? I'd be quite skeptical if there's any benefit going beyond 32 for Chroma.

First I set Chroma upscaling to super-xbr, then focused on Image Doubling settings. NNEDI3 64 on all gave me a rendertime close to 41ms of the video (38ms). Then I changed it so that I only have double and quadruple Luma set to NNEDI3, with chroma doubling/quadruple at Jinc AR.

What is the point in using only NNEDI3 32 neurons if the IQ is close to Super-xbr, which use way less resources and looks about the same? I do have a GTX 1080 card here that I want to take advantage of for MadVr. Trying to find a sweetspot, and was wondering if Jinc AR for chroma doubling makes NNEDI3 for Luma pointless.

[Asmodian]

Trying to find a sweetspot, and was wondering if Jinc AR for chroma doubling makes NNEDI3 for Luma pointless.

No, chroma doubling is independent of luma doubling. In fact doing anything to the chroma will never make NNEDI3 luma doubling pointless. :)

[AngelGraves13]

madshi, any chance of fixing madvr crashing with Nvidia's new "Fast Sync" VSYNC option?

[huhn]

why do you want to use that with madVR?

[AngelGraves13]

I just set it globally.

[zvans18]

I just set it globally.

Probably a bad idea, even outside the context of madvr. It's only meant to be enabled for games you get ~double or higher fps than your monitor refresh rate (so old games, csgo, most indie stuff, etc. Bit more if you're running 60hz with your newer card) Otherwise fast sync's uneven frame pace feels really off and lurch-y

[Betroz]

Have any of you compared MadVr performance between Win8.1 and Win10? I have a Win10 lisence for my HTPC (retail key), but I'm wondering if it is in fact worth it to go and buy a Win8.1 lisence... Seems backward I know, but if I can get let's say ~10ms lower in rendertime, it could be worth it.

Differences are generally negligible. Both OS's are good choices for madVR. I've had no issues with 10, I'd recommend it over 8.1 unless you want to stay in the past or have gripes with 10.
