madVR - high quality video renderer (GPU assisted)

[Oguignant]

Asmodian,

I already resolved it. Was activated only in Windows hdr mode. Now it works properly. Would be good in the future, swichee automatically to 12 bits. I'm forgetting to configure something else?

[Asmodian]

Looks good, exactly like mine except for the language difference. :)

[Oguignant]

Yes, Spanish is my first language. The only disadvantage of the TV I'm using now is the excessive black crush.... but I already bought the new OLED C7P that improved a lot in that aspect. With the new model, I practically do not lose detail in the dark areas with a correct calibration or a 3dlut file, also supports Dolby Vision, Dolby Atmos and HDR10. It has to arrive on Monday. I do not see the time to have it and to experiment with it.

[madshi]

I thought I'd give an update about the issue I had. I 'fixed' it by enabling this option in the nvidia control panel.

When it's turned on (with any setting there) madvr now uses the custom resolutions it made with FSE off/on and DX11 off/on.
Interesting!

I have a gtx 1080ti.
My os is win10 pro creators update 64bits.
And the tv is a lg oled55c6v .
Make sure the OS option "HDR and Advanced Color" is turned *off*. Then in the madVR HDR sections use the default setting "let madVR decide". Finally, in your GPU control panel, make sure the GPU outputs RGB Full (0-255). With this config, HDR content should automatically be sent to the display mostly untouched, and the display should be switched into HDR mode automatically. For this to work, LAV Video Decoder and madVR must be directly connected, with no ffdshow raw in between.

Information about my monitor is not true with some parameters

https://t12.pixhost.org/thumbs/265/49852865_kkkk025.png (https://pixhost.org/show/265/49852865_kkkk025.png)

Bitdepths=10 bit
Widegamuts=Yes
The EDID of your monitor doesn't seem to report 10bit or wide gamut support. madVR can't magically guess what your monitor can do, it can only list what the EDID reports.

Ps what graphics card recommend me. Good, but costs just over 150 euros
PCE 2.0
Maybe Nvidia 4GB 1050 Ti?

If you are still interested, there are two screenshots of same frame with virtualy croped 1920x1080 from top 256px and from bottom 256px too.
In both I captured actual picture frame (shortcut is in potplayer ctrl+alt+E.
I resized the picture to half because of size.
EVR is propertly captured as 1920x568 and is here

@Bernix, I can see the cropping parameters in the MKV if I look at it with mkvtoolnix, but when using LAV Splitter + LAV Video Decoder, madVR doesn't seem to get any cropping information, so the cropped video looks exactly the same as the uncropped video on my PC, using LAV + MPC-HC. Which media player, splitter and decoder are you using?

If you set your output to full rgb, make sur you set up your tv properly to use full range :
Picture -> Picture Mode Settings -> Picture Options -> black level -> High

@Madshi

EDIT: VLC ignores it too, as well as all(almost?) tv our too.

I am using default potplayer settings
In second I changed decoder from Native DXVA to FFmpeg


(1) Built-in MKV Source
(2) Built-in Video Codec/Transform
(3) Madshi Video Renderer

But even with

Result is same

Sorry I am noob in video, I think problem will be obviously on my side. But everybody, who instaled potplayer on clean computer and then install madshi should have same result.
Thank you very much.

[Thunderbolt8]

is anyone able to say how much bandwith (gb/s) a GPU (with HEVC support) should have if you want to be able to play UHD videos (HEVC, but also H.264)

1) on a native 4k display (=without scaling)
2) on a 1920x1080p display (=with SSIM downscaling, 1D/2D)

without frame dropping?

[Manni]

I also use all my content in 23 or 24 mhz with my gtx 1080 ti. But how do you make it switch automatically to 23mhz@12bits?

Glad to see you've sorted it out. Yes you have to select 12bits in 23p and then the driver switches automatically to 8bits for 50/60p.

[Bernix]

Ok, found the problem
it seems to be in Potplayer Matroska Build-in MKV Source/Splitter.
It is handle the virtual croping, when I change it to FFmpeg MKV Source/Splitter , none video is virtualy croped.
But I think it is useful thing. So it would be nice if it works for Madshi too.

It's hard for me to say if the bug is in the Potplayer MKV splitter or in madVR. Could be either. If the problem only occurs with one media player and one specific splitter, then it's not very high on my priority list, to be honest.

[Bernix]

If only there is some other software supporting virtual crop in mkv files.
Thank you anyway.

[madshi]

You could try to ask nevcairiel to add support for that to LAV Splitter/Decoder. If he adds it, and if the same problem then also occurs with madVR, then I'll look into it. I'm not sure if he's interested in this kind of feature, though.

[nevcairiel]

Not at this time.

What filters should I use to have a good video quality with the small gt730?
thank you so much

[chros]

Thank you anyway.

But there's an auto crop black bars feature in madvr as well.

[njfoses]

My pc is connected to my avr, which is then connected to my display. I have updated to the latest 0.92.1 version, but i do not have the custom modes tab under display modes. Do i need to run my display directly to my pc for this functionality?

[Bernix]

But i think it doesnt solve problem why I want virtualy crop the video. But yes, avisynt has very sophisticated way to detect croping.
Not always are black bars fully black.
Thank you anyway

For the last part I have absolutly no clue about what you said.
Should I install lav external filters?
If so how to setup them?
Ffdshow?

That's why I asked if there was a good and complete tutorial, i know very little (one could say i know nothing) about how i should set everything

[madshi]

If you don't know what I'm talking about (ffdshow) then it most probably doesn't apply to you, so you can ignore it.

[zipeldiablo]

Okay :)

I finally found something on youtube.
So from what i understand i am supposed to disable everything in internal filters and hevc-h264 in transform filters is that correct?

Hdr activates now when i launch an hdr movie but i expected more vibrant colors, not sure everything is working properly.
(subtitles and the white bar from mpc-hr are quite brilliant though)

ps : i see there is lots of changes on the image upscaling, is there a consensus now on what are the best settings for this when there is enough horsepower ?

[dvd1]

You've already asked that and got more than 1 reply, as far as I remember.


I asked a lot about the 576 to 1080p but not the 1080p to 1080p
It is more impotent color upscaling, on image upscaling the filters have no effect
I apologize, you have patience for me
thank you

[Dorohedoro]

If you don't know what I'm talking about (ffdshow) then it most probably doesn't apply to you, so you can ignore it.

Madshi if I use ffdshow raw I will never be able to use your hdr options? I love the denoise options of ffdshow.

Thanks mate.

Is it necessary to use 8 frames presented in advance, without using smooth motion. Or 4 are enough in example (nvidia driver sends maxium 4 pre-rendered frames), and will it affect the smoothness of the playback?

[aufkrawall]

GPU queue shouldn't be smaller than 8 frames, otherwise DXVA deinterlacing won't work without drops.
Presentation queue can be smaller, it doesn't affect smooth motion. Just set what is reasonable to be safe (1 isn't).
Why should the Nvidia driver limit madVR to 4 frames presented in advance? The default driver setting is "app controlled" and setting a manual value only affects D3D11 FSE.

I was just pointing the gpu driver as an example, there it says 4 frames is the max, I was wondering how it is better for madvr the default setting "8" or it could be lower like 4 frames in advance, i'm not using smooth motion.

[aufkrawall]

more frames buffered = bigger safety buffer, but more VRAM consumption and input lag (e.g. for mouse wheel volume adjustment)
Presentation queue depends on CPU & GPU queues, so if they run empty, you don't gain much by having a longer presentation queue.
imho: Just avoid overly long or short values. With native D3D11VA decoding, I'm using a presentation queue of just 4 frames. Haven't encountered any problem with it, it remains filled while using the webbrowser at the same time etc.

[jeryll]

When you play HDR demos in 10bit D3D11 FSE mode, is madVR v0.92.1 able to automatically switch your TV into HDR mode (with HDR default setting = "let madVR decide")?

Hmm, for unknown reasons with ver. 0.92.1 i can get ONLY 8bit FSE - at least that's what is OSD showing (and no HDR content is automatically recognized by TV as HDR with "let madVR decide" (FYI - TV recognizes and announces HDR, HDR10, DolbyVision))...

With ver. 0.91.11 I can get 10bit FSE (but result is the same - no HDR content is automatically recognized by TV as HDR with "passthrough HDR content ... + send HDR metadata checked ...").

[Asmodian]

.... but I already bought the new OLED C7P that improved a lot in that aspect. With the new model, I practically do not lose detail in the dark areas with a correct calibration or a 3dlut file, also supports Dolby Vision, Dolby Atmos and HDR10. It has to arrive on Monday. I do not see the time to have it and to experiment with it.

I am actually using a C7P, the 55". The black crush isn't bad at all, only 17 is crushed into 16 with clipping test patterns (Calman 2017 Color Cube 3DLUT, i1Pro2). I am very happy with the image quality overall but it does seem oddly bad at gradients (banding).

Is it necessary to use 8 frames presented in advance, without using smooth motion. Or 4 are enough in example (nvidia driver sends maxium 4 pre-rendered frames), and will it affect the smoothness of the playback?

I use 4 frames presented in advance myself, I have found that to be optimal for minimal latency without presentation glitches or dropped frames. It works well for me even with smooth motion on a 144 Hz display (only 27.8 ms of buffer). :)

Also sometimes the driver (or maybe Windows 10?) seems to behave a little better with a small present queue (3 or 4), though it doesn't seem to matter with my current Windows version and driver combo. The "better" I noticed was a lack of presentation glitches with higher GPU loads compared to larger present queues. The sizes of the other queues didn't have an effect.

I used the default "8" but sometimes for a second it goes to 5 and then up to 8 during rendering times of around 15ms-20ms, so I decided to try your method with 4 frames in advance. :) Thank you for the tip.

thank youWhen you watch 1080 video on a 1080 display in fullscreen, no image scaling is needed, only chroma upscaling, so just use a chroma upscaling option that looks best to you.

Wouldn't a 4 frame queue go down to just 1 at those moment when rendering times spike?

try NGU AA or super xbr for chroma. the depends a lot on your screen too.

Thanks for confirming, unfortunately that's the behaviour to be expected from an HD7xxx GPU, which means no metadata makes it to the display. This isn't MadVR's fault, it's the driver/GPU that doesn't support HDR metadata, so the display can't switch automatically.

If you can switch manually to an HDR mode on the TV, you should be able to display HDR fine (although probably not with great bitrate/quality given the lack of GPU power and h/w acceleration for HDR10).

@Madshi, looks like it confirms there is no point trying my HD7870, unless you think Windows 10 would make a difference (I don't think so).

[Manni]

@Madshi

Given that it looks like I can't help with my old 7870, you might want to ask in the Linker, Integral (and 2015-2017 JVCs as many JVC users have purchased either of these) threads on AVS for MadVR users of the Linker/Integral with a recent AMD supporting HDR to provide the feedback you need. Although these older devices don't have an OSD like the Vertex, they have the same ability to capture the HDR metadata (from the Windows GUI), so they could provide the same information I did (just the raw HEX, not decoded). Off the top of my head, I think at least Javs and Zombie10K are MadVR users, but whether they use Nvidia or AMD I couldn't say. Most of them are probably on nVidia, but you could get lucky. If you find a candidate using MadVR+HDR capable AMD+Linker or Integral and if they don't know how to capture the HDR metadata, feel free to suggest they PM me at AVS and I'll tell them what to do, it's very straightforward. If you'd like me to ask on your behalf, I'm happy to do that too.

[ryrynz]

Madshi if I use ffdshow raw I will never be able to use your hdr options? I love the denoise options of ffdshow.


Don't use ffdshow for 10 bit or HDR content it will harm your picture quality. Madshi will add native denoising at some point so either use your TV's built in denoising or just not at all, you really shouldn't need it for any decent quality content nowadays anyway.

[cork_OS]

I'm using ffdshow raw due to SVP. Since ffdshow blocks interaction between LAV and madVR, some PAL DVDs and 25p clips are detected as 29.97 and display doesn't switch to 75 Hz mode.

[70MM]

Ive never really been able to understand what madvr settings to use for DVD 480 from the USA and 576 from UK. I upscale everything to 4K with the 1080ti card.

If I set deinterlacing to Auto I get massive repeated frames on the USA 480 discs, if I leave that section unticked its perfect.

Yet when I play a UK disc 576 with deinterlacing unticked I get tearing of the image...
Can someone please help explain how this should be set up for 480 and 576 material?
Everything is perfect for BD upscaled to 4K, but I still struggle with DVD...

[huhn]

first of disabling deinterlancing (unticking it) is generally not a good idea.

and i need a screen of the OSD to say more.

[aufkrawall]

If I had to guess: Increase queue lengths.

[HillieSan]

Yesterday, I have watched a 4K HDR movie with MadVR + MPC-BE + LAV (all latest versions) and the colors were correct in windowed mode and incorrect (=looks pale) in FSE mode. The movie in FSE was not as colorful as in windowed mode.

I use Windows 10 (latest version) with HDR turned on, with AMD RX 480 and JVC X5000 projector (RGB 4:4:4 full).

It is not clear to me if the HDR data is blocked in FSE mode. Turning off HDR gives an ugly image.

Is there a solution?

Switch HDR off in the OS, and don't use FSE unless you need to, it's not necessary anymore for HDR 10bits.

[HillieSan]

Thanks Manni, turning off HDR in the Windows panel did it. I am happy with the windowed mode, because the display does not have to switch between frequency modes all the time. The JVC X5000 is quite slow at switching. In windowed mode it switches at the beginning of the movie and after closing MPC BE.

[pirlouy]

About the display mode switcher, there's something wrong (to me), but it has nothing to do with new custom resolution tool, it was already here before 0.92.
In display modes list, I have: 1080p30, 1080p60 (1080p30 is working)
Now I open a 30 fps file. I'd want madVR to switch to 1080p30 and not 1080p60. But, no, madVR will use 1080p60 no matter the order.

I can understand why: higher refresh rate is often considered better. There's one exception though: motion interpolation.
If I want my TV to do a better motion interpolation, I have to use a lower refresh rate. I know you think the interpolation is the same between 1080p30 and 1080p60 but it is not, and it's from an eye perspective.

So, IMO, madVR should follow "written order" chosen by people, and not "higher from lower order".

[sneaker_ger]

1080p30, 1080p60 (1080p30 is working)
So if you remove 1080p60 from the list it does successfully switch to 1080p30?

[nevcairiel]

I've never heard of native 30 fps content. The only thing I know is 29.97 NTSC, which is interlaced or telecined, so either 24p or 60p. What content would be native 30p?
Interlacing is a key problem here, with at least most "30p" content being interlaced, using a 30p mode would not allow proper deinterlacing, as that would result in 60 fps.

[pirlouy]

@sneaker_ger: for a 29,97 fps progressive file:
If I remove 1080p60, it will use 1080p59.
If I remove 1080p59, it will use 1080p50.
If I remove 1080p50, it will use 1080p30.
If I remove 1080p30, then it will use 1080p29.
