madVR - General discussion thread

[huhn]

1/4 luma is 1/2 chroma so yes could be correct.

[Zenvota]

Is the convergence correction feature going to be added to madvr or is it going to be exclusive to the envy now?

Does anyone know of a way to make madVR custom display modes, use RGB/YCbCr of different bit depths. I asked this over in the madVR / LG thread but maybe someone here knows. Basically in summary, some modes like YCbCr 444 8-bit limited for me is looking best for 2160p23 SDR, but for 2160p23 HDR I will want to set it to RGB 8-bit Full.

Currently when using custom modes, I cannot see any control over these, so I always get RGB 8-bit.

Which media players with MadVR can navigate DVD images?

[el Filou]

I've never noticed any issue with madVR and DVD menus.
Here it works perfectly under MPC-HC and MediaPortal, with LAV decoder in DXVA2 copyback mode and madVR in windowed mode.

[el Filou]

Has anyone running Windows Insider builds on NVIDIA Pascal+ or Intel Skylake+ by chance tested the new "hardware-accelerated GPU scheduling" (https://www.minitool.com/news/win10-...cheduling.html) to see if it gives any benefit with madVR?
What this changes exactly is pretty vague and I don't know what sources those websites that explain what is is are using.

I finally couldn't help myself and got curious on this update.

Need to join MS insider program to get the preview builds. I chose the slow update channel here (semi-safe I guess).
For Nvidia you need to register on the developer site to access the latest preview driver (450.82): https://developer.nvidia.com/directx
Intel drivers auto updated via MS update to latest WDDM 2.7 drivers.

Works like a charm. No proper testing here but I can defiently push things further with madVR.

Ever since I upgraded to Windows 10 all my HDR videos that have the MadMeasureHDR measurements file next to it play almost completely black. Any ideas why?
I upgraded to latest beta (113 I think) and done the HDR measure again and no difference.
If I play the video without measurements file it plays fine with its on-the-fly HDR to SDR conversion, but the picture is obviously not ideal that way.

[SamuriHL]

The measurement files haven't worked in quite a few versions. Disable it in the options for now. The real time is better.

Thanks for the info.

Is real time really better? Just with default settings for all HDR videos? Is there some kind of tuning/optimization recommended?

Also, is it possible yet to play HLG files yet? Even just in SDR mode?

[SamuriHL]

Yes, realtime is really better. But it requires some tweaking. It's going to take a bit of reading and work on your part, but, the results will definitely be better than what the measurement files used to give.

Thanks. I'm more than happy to learn if it means best possible quality.

Can you point me in the best direction which documentation I should read to learn optimal MadVR HDR tweaks?

Is it possible to play HLG files in SDR mode with MadVR?

[SamuriHL]

There's no real "documentation" on the latest betas unfortunately. Usually you start out with someone else's settings and tweak them to your liking. I usually recommend Neo-XP's settings to start with. Right now is not the best of times to be jumping in to the beta builds as they are working out some saturation issues. So things are still in flux as to what might be good or bad depending on your display.

As for HLG I know there was talk of that recently. Not entirely sure. I've no HLG sources at all.

I am unsure which new OLED TV I should buy with regard to using a PC and madVR as the source for playing movies. Between a LG CX and Sony A8, are there any issues I should be aware of that makes one better than the other?

[VBB]

@-sTi- You should check the OLED section at AVS for ad nauseam "discussions" of LG vs Sony. For PC use, the LG is the clear choice, in my opinion, because it has HDMI 2.1. Right now is not a good time to buy either, with CES announcements just around the corner. Wait a few months and see what's available then.

[Klaus1189]

Or scalpers will buy TVs also

[chros]

I wouldn't buy a Sony until they implement TV-led DoVi, currently (many years) they only support player-led LLDV that is crap

[VBB]

That's another good reason, yeah.

[zeus0r]

i'm not 100% sure but i think since the latest nvidia driver update (460.89 - gtx1660 super) video playback with mpc-be/madvr stutters really weirdly. i tried different files and every single one is choppy on random scenes/frames.

anybody else noticed this?

// EDIT

just installed the previous drivers and it's still there, damn. never had any stutters before and i didn't change anything. (that i know of)

[VBB]

@zeus0r - Try this: Set "how many video frames shall be presented in advance" to 1 or 3 (madVR settings->rendering->windowed mode and/or exclusive mode) and/or enable VSYNC in the Nvidia drivers.
