How to export/import madVR settings?

[el Filou]

You can either give write access to the folder madVR is installed in (usually somewhere in Program Files) to your user account and then it will create a settings.bin file in it, or you can export the HKEY_CURRENT_USER\SOFTWARE\madshi\madVR key from the registry (the resulting .reg is quite big, so zip it if you want to share it).

@madshi Would it be possible for madVR to store the settings.bin in %ProgramData% ? That folder has the advantage of having write access even for standard users.

hi

Has the full/limited issue been fixed with new nvidia drivers?
Selecting RGB Full in both desktop section and video section, is 0-255 correctly displayed?

thanks

I'm noticing small white horizontal dashes (most of the time white, but on occasion black) flash on the screen at what may be random times during playing of videos. I've also noticed they flash on quite frequently (although not always) right after I pause videos too. Its a brief flash, and doesn't remain on the screen making me unable to take a screen shot.
(MadVR, MPC-HC 64, LAV-64, XySubfilter)

I'll post my settings if needed, but before that I thought it may ring a bell to a few of you who may have encountered it yourselves in the past. Any theories on what may be causing it, or a setting I should try changing to remedy it?

Excellent, thanks for the info! Much appreciated!

I updated to 385.69 and it's not fixed for me, but then most people don't have this problem so it will probably be difficult to have NVIDIA acknowledge it.

Just one remark: the Dynamic range setting in Adjust video colour section shouldn't have an effect on madVR.

[Asmodian]

Yes, that is very strange. I haven't had a problem with Nvidia + full range RGB in years.

I compare by switching settings and re-watching shorter sections of different types of content.

why jnc does not need overthink?

I was wondering which decoder to use, CPU decoding, or GPU decoding (DXVA copy-back). CPU is XEON X5650, GPU is GTX 1050 Ti.

Jync is a decent enough scaler so you can set it and forget it, if you can't be bothered to do some testing of your own.

Jinc is the the highest quality non-doubling scaler. It is a simple very high quality choice if you do not notice the difference from NGU.

The video block in the 1050 decodes pretty much everything and hardly consumes any power, and it's dedicated so you're not using other processing resources. The only case I'd see in your situation for not using it would be if copy-back mode has problems (usually with UHD content).

I'm not using any processing/enhancement/refinement, and yet on my system the picture looks more similar to your madVR screenshot than to your VLC one (albeit with more banding artefacts).
I noticed that madVR produces a 1920x800 image and your VLC screenshot is 1920x804, the aspect ratio is different. I don't know much about VLC, but what renderer and decoder does it use? If it's DXVA and/or EVR, are you sure your graphics card video 'enhancements' are not processing the image? And how does it produce screenshots? Or did you use print screen?
I also tried basic EVR, and the resulting image is 1920x804 like your VLC screenshot, but with the same brightness levels as madVR. I think the VLC image is the bad one here.

Edit: this scene is a very good showcase of how much better at rendering madVR is than GPU drivers & EVR, btw!

I watch only 1080p content So copy-back is the right choice?

Can someone give me tips for faster skipping/jumping inside low quality formats like porn? It needs 2-4sec to rebuild after jumping with my high settings on NGU AA, but maybe I did something wrong. HD 1080p movies work without delay.

I have tried to lower the setting and deactivate the NGU, but it doesn't really help, so it seams something else is wrong.

I'm testing them but I do not see any difference between the various scalers, maybe I can not figure out what the differences are and with what images i have to do the tests?

Here's a screenshot
GPU deinterlacing is definitely working, no combing whatsoever as in your screenshot.
I left madVR at its default settings.

I may be wrong, but could madVR + GPU deinterlacing be too much for your graphics card? Have you tried with EVR just to see if deinterlacing works without madVR? Have you tried lowering madVR processing quality?

EDIT: I see your average processing time is ~23 ms. 50i video deinterlaces to 50 fps, not 25, so it means 20 ms per frame. I think it's likely your GPU has no processing resources left to deinterlace in addition to madVR processing. I know Radeons at some point had a 'feature' that disabled some video processing options if the GPU was maxxed out, I don't know much about NVIDIA GPUs yet but could it be that's what happening?

I just realize that when you were testing this I didn't know yet that it only breaks when I change channels.
Could you try it that way? (If you're still around)

Maybe you should edit out the boring stuff before playing the video.

Haha

When I skip/jump the decoder queue goes up over the set limit from 16 to 19/21 for a few sec, in this time the video stops.

I'm using a i7 7700k, should I set the decoder queue higher then the default to fix the problem?
