madVR - high quality video renderer (GPU assisted)

"...i will still get presentation glitches if..."

Do you mean to say that zero presentation glitches (let's say, for a 2 h movie) is actually a realistic target that you should strive for, or am I drawing a false conclusion?

you shouldn't get continues presentation glitches with default settings.

It worked well on my ol' 240hz display except for the occasional hang when I would drag it to a different refresh rate display. But MadVR doesn't like the new 540hz panel.

On 540hz, playing a video:
first 1sec of playback: normal playback
2sec-6sec: stuttering playback, MadVR statistics show "display" Hz incorrectly fluctuating from 100~180Hz
7sec-infinity: normal playback

Latest Win11 update, RTX 4090, latest MadVR beta (but also happens on the stable release), happens on any given LAV decoder setting
Happens on MPC-HC or MPC-BE with MadVR enabled
Doesn't happen with MPC video renderer enabled
Also happens when all monitors besides the 540hz one are off, so it's not a mixed refresh rate problem

just VVR running at the start.

Hello, I cannot get HDR passthrough to work with madVR. My laptop is connected to a LG HDR capable monitor via thunderbolt. Enabling HDR in windows just works fine, I see the HDR logo pop up on the monitor. I turned it off cause it's not needed for madVR.
In madVR settings I selected 'passthrough HDR to display' but playing a video just shows washed out colors, also in full screen. The GPUs of my laptop are Intel Irix Xe (11th gen) and NVIDIA GTX 1650 Ti and all drivers are up to date.

I see the following behavior depending on which GPU is used by MPC-HC:

- When using the intel gpu for video decoding (windows graphics 'Let windows decide'): video is not that smooth but colors are not washed out. Note: Colors are slightly brighter/vivid when I select the passthrough mode than with 'let madVR decide', but HDR is never triggered on the monitor.
- When using the NVIDIA gpu for video decoing ('High performance'): video is smooth but colors are washed out no matter which option I select for HDR in madVR.

Your help is appreciated.

check on madvr that the hdr monitor is the first in the list of devices

when I open an hdr file, it is not bright, the colours are pale.
I have the default settings on madvr, except 10bit, hdr passthrough, display mode and FSE (fse not working)

any tips?

Keep it on. If you enable Windows HDR then madVR will use the standard Windows HDR APIs, which nowadays are more modern and better supported than the GPU-specific APIs (which mostly only exist for historical reasons at this point) that madVR would use otherwise.

It's quite likely that your problems are caused by GPU-specific HDR APIs not supporting your hardware setup well (i.e. Optimus laptop), and you'd have better luck avoiding them.

Happens with g-sync disabled and in windowed mode, which doesn't trigger g-sync, so I don't think it's possible

so we can use OS hdr? because it fixed my problem

VVR works in window mode for a long time now.

seeing the screen fps rise from 220 to 240 is just normal here on one system.
still a bug but nothing will change about that here.

No matter whether I use FSE, only the full screen mode of MPC-HC, or only that of madVR (matching display mode), and also regardless whether I have optimizations on or off (or running as administrator or not), it's always somehow glitchy. What I mean is I very often have to start the video multiple times before I get full screen to work, as it so often only shows black. Now for the first time it dawned on me that I might have a larger problem with full screen, as I connected this to the fact that even Chrome is glitchy (flashes when scrolling, videos showing faded colors) after hitting F11. Any thoughts or suggestions?

Amd driver crashes sometimes with 4K movie and needs system restart.Updated driver and even tried DDU but it happened again.Any ideas?

[Schwartz]

Sticking to DXVA2(Copy-Back) in LAV was what made video stable for me with my older R9 AMD card.

[Damien147]

D3D11 in LAV is very convenient for me to use.The crash happens only with 4k movies and sometimes,not always.If it happens it will happen at around half of the movie.It's not such a big problem but it would be nice to fix it.My PC is old and is on fire when I play a 4k movie.Maybe it crashes because it's ''overloaded'',I don't know.

Probably a faulty power supply, run some system tests.

[Damien147]

Ok,I will check.Thanks guys for guiding me.

[Sunspark]

Do a memory test too.

[Damien147]

OK,thanks.

I need some help with madVR...

This is the first time I noticed this issue, with madVR and MPC-HC / MPC-BE.

MPC-BE x64 1.6.10
Filters currently loaded:
- Default DirectSound Device
- madVR Renderer
- ffdshow Audio Processor
- LAV Video Decoder
- Audio Switcher
- MPC Audio Decoder
- MPC Matroska Source

RGB subsampled, well, now that's something.
Wrong container info, and poor renderer believes it ?
VD2 chaching input driver 2.1 assumes "yuv420p (?)", and I would do the same.

P.S. To avoid ambiguity: I did not mean to call renderer "poor" as in "poor quality",
rather as in "could not know better, has been misinformed".
In German this is a valid first notion as in "armer Kerl" = "poor guy",
but now I see that it might have left a different first impression in English.

[Sunspark]

It's only MadVR that has the problem.. the other renderers can play it.

That said, why are you using such a low-quality file? It looks like it came off VHS tape or something.

[huhn]

madVR has no problem the file is flagged wrong.

the issue at best is a sanity check that ignores RGB flags when a file is subsampled that is missing here.

following flags even barely sane ones is not a wrong behaviour.

This is a VHS capture (made because of the audio content, not the image itself, which I already have in 1080p). Do you all suggest a new recording?

Also, is there a chance (since my source is from Brazil) it's in PAL-M? https://en.wikipedia.org/wiki/PAL-M

Back in the 1990s this was the system used for TVs, which is different from regular PAL and NTSC.
