madVR - high quality video renderer (GPU assisted)

[dvd1]

scuste my English. I'm a disabled boy, I do not walk. My only fun is the TV and the PC. I do not have much money, so I have to keep my old gt730 for a long time. I would be happy if you help me get the most for DVD profiles, 720 and 1080p. How to set up nvideo control panel, set LAVs, and set madVR to save resources and have good video quality
thank you so much

Ps what graphics card recommend me. Good, but costs just over 150 euros

Information about my monitor is not true with some parameters



Bitdepths=10 bit
Widegamuts=Yes

thx Madshi

Sorry I can't help with that...

RGB Full 4:4:4 12bits... Manni, how is that?

Great, why?

EDIT: Sorry you probably thought I was still using an HD7870. I don't. I have an nVidia 1080 Ti. I just haven't sold the HD7870, but it's not being used (I was talking about when it was used in the post you quoted, and of course that wasn't RGB Full 4:4:4 12 bits with the HD7870). See the rest of my sig

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?

[Oguignant]

Does anyone clarify this for me? I always use RGB full 8 bits in D3d11 exclusive mode (10 bits) recently, I discovered that I can use for 23, 24, 25, 29, 30 mhz in 12 bits enabling RGB48 in Lav Video decoder and disabling all other options. I have to also change 12 bits to RGB full in 23, 24, 25, 29 and 30 mhz in nvidia control panel too? Is there a way to do it automatically from "display modes" from Madvr config? Or just modifying since Lav Video decorating is enough?

[Asmodian]

No, that is not the way to get 10-bit!

NEVER disable any color modes in LAV Video for maximum quality. nevcairiel has said before that conversion to RGB is not done at maximum quality in LAV (the chroma must be scaled by LAV to do this). You want madVR to receive the decoded but untouched video from LAV, not force LAV to do a quick and dirty conversion to RGB48 for no reason.

Only change the bit depth in the Nvidia control panel and madVR (the display's property).

Sadly madVR's new custom modes seem to only be 8-bit modes. However, if you set a standard 23-30Hz mode to 12-bit in the Nvidia control panel and then do not set the bit-depth to anything when switching back to 60Hz (the box goes blank on my system but is using 8-bit in >30Hz modes) when madVR automatically switches to a mode that supports 12-bit it does use 12-bit.

edit: The line in madVR's OSD that is confusing you is the one that looks something like: "h264 8 bit 4:2:0 -> NV12 8 bit, 4:2:0"?
That line is only discussing the source, in my example the video was H.264 8 bit 4:2:0 and madVR received it as NV12 8 bit 4:2:0 video data from LAV (madVR only reports the codec for H.264, everything else only has the bit depth and sub-sampling/RGB).

Perfectly clear! Thks! Then the 12 bit change should do manual. Another question, In Lav Video decoder I use this option "Untouched (as input)", or I should use "PC (0-255)"

Another thing, when I change Nvidia cp 23 or 30 mhz 12 bits active HDR on my TV, I do not know why, what can be happening?

[Asmodian]

No need to quote me.

I leave it on PC (0-255) because this matches what I have madVR set to output, in the extremely unlikely event that LAV needs to covert to RGB for some reason. This usually has no effect when using madVR.

Maybe you have the Windows HDR option enabled? It auto disables itself if you switch to 8-bit explicitly and re-enables itself when you switch back. On my TV HDR only activates when I pass it metadata, either by using the option in Windows (which is only present in a 12-bit mode, or when that box is blank because I switched to 60Hz from 23Hz 12-bit), or by having madVR send it. 12-bit by itself doesn't switch my TV to HDR.

[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.

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!

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.

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.

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

but Madshi is not properly and is fullscreen 1920x1080 and is here

Otherwise the link with 4 videos are here (different video than this screenshots)

But with zero download...

@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?

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.
