madVR - high quality video renderer (GPU assisted)

Asmodian, madshi,
is this true also when the "passthrough HDR content to the display" and "send HDR metadata to the display" are enabled? I don't think it would make any sense to do so having in mind that by default the TVs (and may be also projectors) will switch display modes when it receives the HDR metadata and this means (usually) totally different configuration/calibration including support for the wider color space.
I'm a bit lost on this topic but I have the feeling that we need two separate sections (one for SDR and one for HDR) for telling madVR how our displays are calibrated ... or am I missing the whole point here?
I apologize for asking this question again but I simply can't believe that madVR will behave so user unfriendly to downconvert everything to BT.709 and pure power 2.2/2.4 including real HDR content.
btw
what will madVR output in these cases (BT.709 SDR source and BT.2020 HDR source) if I select "disable calibration controls for this display"?

[huhn]

hdr pass through is not effect by this only sdr output.

i mean common how can you pass through meta data and convert it to gamma at the same time?

[pankov]

OK,
now that you say it like this I kind of see the stupidity of my question.


but just to be sure - the same applies to the other two options that output HDR (process HDR content by using ....), right?
And the calibration settings are actually in effect only when there is native SDR content or a conversion from HDR to SDR using either pixel shader math or external 3DLUT, correct?
If that's the case may be the calibration tab should be renamed to "calibration for SDR content"

[huhn]

you can read it in there pixelshader is by default converting it to DCI-P3. i guess it is still sending bt 2020 or at least DCI P§ and says it the screen.

and using a 3d lut is well doing color correction by using a 3d lut.

I'd like it a bit sharper?

[huhn]

it's chroma we are talking about it has little effect.
you can try super xbr.

you can try adaptive sharpening what ever you like but don't expect it much from a 740.

I turned on Sharpen Complex 2 in MPC-HC.

Any special recommendations for Chroma, Image and Dithering for a 1080p video on a 1080p screen, when used in combination with MPC-HC's Sharpen Complex 2?

You could try the image enhancements in madVR instead. You could also increase the strength of chroma upscaling to medium or high, if possible, but this will only have a small impact.

The rest wouldn't change.

I changed NGU to Soft and combine it with Sharpen Complex 2. It doesn't look way too sharp or not sharp enough.

If there are any reasons not to use NGU Soft, do tell!

[Asmodian]

Did you compare it to NGU AA? I usually prefer NGU AA over Soft but if you like soft more there is no reason not to use it.

Yeah, NGU AA and Sharpen Complex 2 was too sharp. NGU AA w.o. SC2 I find too soft. Shoot me, but I really like SC2.
On my older PC I combine it with good old SoftCubic80.

With madvr should i use VSFilter or xy-VSFilter?

[Asmodian]

I prefer XySubFilter, though I believe there is a known issue madshi would like fixed I never encounter any problems with it and I am not sure what the issue is. It renders to madVR in higher quality than other options. xy-VSFilter over VSFilter for performance.

Anyone know how you can force Nvidia to switch to 12bit output whenever MadVR switches refresh rate to 23/24 Hz? It's at 8bit everytime so I have to go to settings and change to 12bit.

[Asmodian]

No. If you find a way please let us know.

Newer drivers using 12bit do not survive a reboot last time I tested. Use an older driver. I suggest 385.28. Cures an audio problem too. On the other hand, newer drivers (help) with frame drops better than older drivers but they only help, not cure. Also, 12bit is only good for displays and/or PJ's that handle 12bit correctly. Otherwise, you will introduce banding. The difference between 8,10, and 12bit is not going to be as noticeable as many assume imo but striving for it is closer to perfection.

There's only two options, 8bit or 12bit.

I watch 4k Mastered HDR Blurays, who have native 10bit I believe.

Would playing them back in 8bit Nvidia setting lower the PQ?

Asked about this some years ago and madshi said 10-bit wasn't exposed as something that could be switched to outside of Nvidia's control panel. Maybe now that he has a contact he might be able to suggest this as a feature to add.. I hope they get 23Hz profiling and the bit depth bugs fixed this year...

[brazen1]

I think 12bit dithers down to 10 even though NCP doesn't report it. Look at the OSD. Also 10bit can be selected but only if you use 4:2:2 which I wouldn't reco just to gain 12bit at the expense of using a limited color space. RGB Full 10bit addition 2D and 3D with proper 23/24Hz timings would be perfect..... and fix the audio bug.

Does anyone know when this went wrong? Are you sure it isn't a custom resolution that is causing this?

I went through the pain of editing this post recommending this configuration: https://forum.kodi.tv/showthread.php...438#pid2739438.

It seems kind of pointless if this doesn't work.

It would also be nice if someone more technical than me read through the guide posted in my signature. I went the through the pain of editing the entire thing for improved language and technical accuracy. My feelings would not be hurt if anything is inaccurate. I should move all of that content elsewhere, so it not stuck in the Kodi forums. The Kodi forums are just so easy to edit and format. If I can find a browser that makes editing easier, I would post it at AVSForums.
