It would be great if MadVR could do this, but for some reason Madshi doesn't seem to be willing to go all the way for 3D support with nVidia. He has provided registry settings that help momentarily but don't stick. The only way is the batch file, so if we could get MadVR to launch a batch file on 3D playback that would be very useful as it could be automated and wouldn't have to be manual. On the other hand it might be too late to start the file by the time playback starts, so we'd need some delay as well.

can you post your batch file please.

thanks

You didn't need to quote the post mclingo.

So I was having the IRQ issue with MadVR in Windows 10 with Zoom Player using it in FSE, disabling forced FSE solved the blackscreen/IRQ issue.

Now upon exiting after a long viewing session I get a BSOD that says "attempted execute of noexecute memory".

It happens immediately after clicking Exit.

This only happens with MadVR.

Edit - Seems I've been using MadVR 92.8.0 will see if it happens again next time I watch a movie.

Blue Screens are not caused by software, they are caused either by broken drivers or broken hardware.

But the IRQ error is caused by FSE mode in W10

[Anima123]

Windows 10 doesn't like FSE so much. However, the windowed full screen mode has been enhanced, which can be considered substitution of FSE to some extend.

My i5-Haswell downscales 4k@24/30fps hevc hdr movies to 1080p fine using CPU decoding and iGPU dxva.

Hey,

I noticed something the moment I switched from Potplayer x86 to Potplayer x64. The frame drop literraly drops down (from several hours in x86 to few minutes in x64). I checked everything regarding Madvr then I asked myself if it wasn't related to audio - since Reclock doesn't exists in x64.
And the result was obvious. If I switch the Reclock option back to default (in Potplayer x86) I have the same drops down I have in x64 application.

What I understand is Potplayer is more demanding for outputing audio than Reclock and this loss of performance is impacting Madvr?
What alternative or settings should I change to properly use this x64 app?

I'm thinking, maybe I should directly ask to Potplayer cause I bet Madvr is not the faulty one in this case?

cheers

The main issue with NVIDIA for me was 3D, its just not reliable at all, sometimes it works, often it doesnt. I was also getting for more black screen and HDMI signal loss with my 1050. HDR is also a problem, its broken at the moment, a fix is coming but they will likelly break it again.

My AMD 550 is pretty stable now but it still freezes my PC now and again coming out of a video playback, although i've gone back to 17.10.2 and it hasnt crashed for over a week. HDR is spot on with my AMD card, no issues at all, perfect glitchless playback.

My current preference is AMD as I have perfect playback of everything with only the odd pc hang on newer drivers, I dont game so there is no rush for me to keep up to date.

So Rx 550 is powerfull enough to upscale 1080p -» 4K with NGU antialias high???

[huhn]

depending on the used scaler yes for sure make sure it is a 4Gb version.

edit: NGU high no way...

madVR is not the problem, but it's potentially your solution.

Make sure you're using the latest version of madVR, then read madshi's tutorial on creating custom resolutions for your TV/monitor. When you find the right custom resolution, your frame drops will go back to days or even longer and you'll have no need for ReClock because your audio and video will be in perfect sync.

This is the drivers fault. The software says FSE mode please, and the drivers do something that crashes the system.

FSE mode uses parts of the drivers/hardware other modes do not. Software has to access the hardware via the drivers, it has no control at the IRQ level. Software can sometimes work around driver issues to avoid them crashing but not cause a blue screen itself, at worse the software crashes.

Thx for the tuto, I didn't know about those custom settings... And thx to it I understand a bit more why I loose such of "frame drops every". It's all related.

First of, my TV accepts all framerate (from 23 to 60). I followed his tutorial but unfortunately I can't choose no "optimized pixel clock #" because the gpu don't accept it. :/ I have a GTX 970 by the way.

So my new BSOD is an issue with Nvidia display drivers ?

I'll watch a movie tonight and see if it crashes upon exiting since I'm using the latest MadVR now.

Are you having problems USING the optimized setting or SAVING it? If using, make sure your custom res is in madVR's list of resolutions to automatically change to (for example, "1080p25" or "720p25").

If you're having trouble saving it (common with Nvidia), try changing the display resolution in Windows to something other than the custom resolution. For example, if you're trying to save a 25Hz resolution, use Windows display adapter properties dialog to set your TV to 60Hz, then try to save the 25Hz again. Doesn't always work, but it does sometimes.

ive had similar issues, mine doesnt blue screen it just hangs, i get a black screen and the pc is dead, I have to power cycle it, nothing in events, no mini or memory dump, nada, at least if you are getting a BSOD you can check where its coming from.

I was also getting random black screens when coming out of movies for no reason, with identical settings I didnt get the same on my AMD card.

All the issues we are having awith win 10 t the moment seem to stem from the fall update, my system was stable before that.

Have you tried a full clean install of GFX drivers, LAV and MADVR?

Yep USING it. But now I think it's all good I don't know how or why but I could change and save the "optimized" setting for the 23fps. I succeeded to achieve more than several days reaching the "no frame drops/repeats expected" sometimes.

Thx again for pointing me this new tutorial and for your time.

[Ceremony]

is there a way to quickly "convert" a few clips (which still amount to a few thousand frames) through madvr processing without manually screenshooting every single frame?

I know its not the intention of madvr, but I need to convert them as the hardware i plan on showing the clips on unfortunately do/can not run windows or madvr. The enhancements i set within madvr (upscaling, debanding, post processing and so on) do make a huge difference when I tested a short ~5sec sample using the painful screenshot method. obviously, frame deliver is not optimal, but overall quality at near lossless reencoding does work wonders. anyone got a nice script or some tool capable of going through all the frames and exporting them as PNGs or something for further conversion in the appropriate format?
