madVR - high quality video renderer (GPU assisted)

[YGPMOLE]

Sorry for bothering you all with a dumb question, but I changed my JVC PJ and now I have two level of calibration: SDR (Rec. 709) and HDR (BT. 2020); I created the relative profiles in madVR with a rule and works fine!

Is there a way to make the PJ automatically switch between the two calibrated profile by a madVR instruction?

report bt 2020 to display flag with the same profile.

On windows 10 1809, it will trigger and hold hdr. even in non fullscreen exclusive.

There's also a pause now for the picture to come in when video files are initially opened..

HDR should work in windowed mode too, at least for me it does on win11 and 6900xt.
I noticed the pause/black screen before playback a few months ago, not sure why it happens or how to get rid of it.

Thanks, I already tried that but MPC-BE crashes after few second of watching the video, so I though I was missing something.

Even without it, the PJ recognizes that the color space received is bt 2020, but just remains on the SDR memory bank.

Ok, I sorted out and now it works: the only problem is that it doesn't switch back!

I mean, once it goes on the BT. 2020 memory bank it remains there even if the playback stops; it switches to the Rec. 709 memory bank playing SDR contents, but when they stops it goes back to BT. 2020.

Windows desktop and Kodi menus are SDR...

What's your whole stack look like.

I am using 7800x3d, b650, 7900xtx, win11 os build 26100.2605, amd driver 24.12.1, madvr v113, mpchc.

I have a 6950xt as well, I've tried that same behavior.

On my windows 10 build, it works like you said. Even outside of fullscreen.

[strumf666]

5800x, b550, 6900xt, marantz cinema 40, lg g3, win11 26100.2605, amd driver 24.12.1, madvr v207, lav filters 0.79-20, mpcbe.

Hi All,

I am experiencing "presentation glitches" every second since updating my windows 11 to 24H2.
I have madvr matching the display framerate and video framerate. (23,975xxx or something)
I am running a 13900k with 4090RTX with MPC-HC with MADVR 0.9.17 with measure 207 update.
In NV Control panel I set MPC-HC profile to prefer maximum performance and Vsync ON.

All was running fine until after the update to win11 24H2.
Since the update I see all stats being stable when starting a video and going to fullscreen.
After a few seconds I see the "presentation glitch"-counter report one every second and letting the playback be stuttery.
It also seems the refreshrate shifts back to 23hz iso the normal 23,97x it normally has.

Furthermore I tried MPC-Video renderer as a substitute but there it starts rendering fine in fullscreen but after 10 mins the "present timer" increases to 40-50ms and introduces stutter.

The second I roll back to Win11 23H2 ALL ISSUES ARE GONE! and playback is stable as Always.

Does anyone have a (temporary) solution for this and is there any hope this will be fixed by either MSFT, NVIDIA or MADVR?
Setting the disable desktop redering setting in MadVR didn't help, Setting the "disable fullscreen optimization cpompatibility setting in .exe properties didn't help, and disabling Vsyc in NV Control panel didn't help.

Disabling HAGS also doesnt provide consistent results, it does seem a bit more stable but also is not able to play a full 1,5hr movie without stutters.
And disabing HAGS will be a miserable bother as I play alot of games with FG on (which requires HAGS).

have you turned game mode off in windows, apparently this can cause some issues.

Im thinking of getting a new GPU. I use the Samsung Q90R 4K TV 2019. I want to use very high settings with Processing and Upscaling in MadVR. Very high setting on every front. I was thinking of getting the RTX 4070 Super or should I wait for the RTX 5070 Ti? What RTX GPU should I get? Does MadVR want high VRAM?

[Asmodian]

There is very high on every front and then there is 8K doubling to 16K with NGU very high with all pre and post processing enabled.

How reasonable are you being with "very high setting on every front". A 4070 Super would be a great card for madVR, very high on everything that is even slightly reasonable, overkill even. It won't do very high on absolutly everything at once though (but that would be worse quality even if it could).

With today's GPU memory sizes, no madVR does not use significant VRAM.

I'm with 4070 ti, and on very high upscaling to 4k, it does really well around ~ 12 ms. Even with some additional settings: dithering, smooth motion and etc. The difference between high and very high can be seen, not by everyone, but I can see it.

Can the brightness of subtitles be changed? They are too bright in Hdr, but ok in SDR.

Your player should have a setting to change for this

Although I have yet to use this change on SDR subs since I did it, so I am not sure if it is too dark now for SDR....

Unfortunately this also doesn't resolve the issue.
Is there ANYONE running Windows 11 24H2 without MadVR & MPC-VR fullscreen playback stuttering/issues?

would be good to understand bcuz I only see people who report problems with it.

[strumf666]

Depends on how much of a nitpick you are, for me, both generally work, but nowhere as smooth as streaming apps on the TV.
It also happens that either of the two doesn't play a file properly or at all, but it's quite rare.

[Sunspark]

You don't need to have your subtitles at #FFFFFF/RGB 255 255 255 pure white. Change it in the player settings to a tonality that is comfortable for you (more gray).

Can you post a screenshot of your madvr stats, I have had a couple of issues in the past were I have had to completely wipe the drivers using DDU and start again from scratch.

I have been seeing this crash in MadVR off and on recently.

Running Win 11 and beta 207.

I have attached the crash report.

I got an OLED and I watch a lot of 4:3 with black borders down the sides and I am worried about burn in over the next 5 years of watching 4:3 stuff.

Is it possible with madvr to do something with the borders like colour them grey instead of black?

Is there an alternative media player that has options for this?

Currently using MPC-HC and it has loadable shaders so I was thinking maybe a third party shader could be used to do that, maybe even something fancy like drawing a fake frosted glass reflection down the sides like the megabezel shader for retroarch
