hey i just want to give props to madshi.
Madvr is so great at upscaling 1080p to 4k , it even looks better than some native 4k stuff

I think my next laptop will be fanless and probably use ARM.
Will madVR support ARM machines?
Is a new release planned this weekend?

What's new with Latest version

0.71 / 0.71.0-35 Nightly (May 12, 2018) ?

there's nothing on the changelog about this specific version

This is the only recent commit, so 35 is probably functionally identical to 34. Might have been built with a slightly newer version of Visual Studio.

Are you watching 4K movies on a display with a resolution lower than 4K?

If yes, turn off the trade quality for performance option "scale chroma separately, if it saves performance". This option will let madVR avoid scaling chroma if it doesn't have to, instead scaling luma to reach the same resolution as the chroma. Effectively this is still converting to 4:4:4, but it is probably lower quality than scaling chroma to match the luma and then downscaling in RGB.

Madvr stops working on Win 10

Hi all,

I am using madvr 0.92.14 on win10 build 1703 and it stops working as soon as I want to change settings (see attachment). Any idea why this happens or how to troubleshoot it?

Thanks.

Ronald

I'm surprised there is no chroma appeared on madVR OSD.i don't know what's going on?Chroma is not displayed all the time when the playback of 4K UHD movies
Third:
Due to no chroma used, the conversion of 4:2:0 format to 4:4:4 format doesn't always work.This leads to worse video quality.I don't know how to solve the intractable problem.

Have you activated supersampling? (doubling action - always supersample).

It takes a fair amount horsepower, so you might need to adjust your settings for 4k movies when it's activated.

Master,I've done the test again and again for 5 hours this morning.I get now a best way to solve the intractable problem that i expand horizontal and vertical pixels to exceed the active pixels the display allows.Chroma upscale appears now.It works perfectly.The colors of 4K videos look very great.I'm sure the conversion of 4:2:0 format to 4:4:4 format is successful.Thank you very much

I didn't reset what you said above about supersampling.I just did as master Asmodian mentioned in madVR specification.Nothing more was reset by me.Thank you very much.

I found out that restoring settings to default solves the crashing issue, I will have to reconfigure madvr...

Custom modes used to work for me, at least with some resolution. I was mostly using 3840x2160@23. I recently changed some hardware, switched to Windows 10 and despite the fact that I have installed one of the recommended NVIDIA driver, custom mode is broken.

Do any of you has a "strategy" to try to identify what the problem might be? Despite doing a clean install of the recommended driver?

I would also be interest to have some feedback from users using custom modes at a very specific resolution, eg. 4096x2160@23. I'm a Sony projector owner and this is now my default resolution.

Thanks.

On a completely different topic, I would also suggest to clarify the scaling tabs. I feel like it could be better. Isn't possible to clearly differentiate between luma and chroma scaling? I remember one build with four options: chroma doubling and quadrupling, luma doubling and quadrupling.

Anyway, love madVR. Excellent job!

The x86-to-ARM emulation is limited to 32-bit though, isn't it?
A native ARM64 binary would be faster but I don't think most developers would bother.

Install Geforce v390.65 driver, it's the last one that doesn't have the fubared custom resolutions.
I tried every single driver after that, they just do not work properly with custom resolutions.

3d mvc

Hi, can someone help me? I've done a bunch of research but cant find a solution for playing a 3D MVC file.

Im running latest LAV and MadVR in MPC-HC 64bit on Win10 64bit, on a intel i5-4250u with HD 5000 graphics. Im using DX11 decoding.

I have 2D movies working fine but when i try to run a 3D MVC frame-packed file, while it displays properly on the TV, its very slow and the CPU is at 100%.

Any way to make LAV/MadVR work smoothly for these 3D movies or does my computer not have enough power?

thanks!

the i5-4250u that can boost quite a lot. check the temps.

you are not using d3d11 decoding is software decoded there is no support for hardware MVC in lavfilter. h264 is not a real problem for most CPU but the i5-4250u is a dual core with 1.3 ghz...

i'm using an ageing i7 2700k, this uses anything from 30 - 50 % cpu on my rigg, this cpu is about 3 times faster than yours in benchmarks so its likely you are over taxing it and your setup it fine.

you're going to need to upgrade the CPU i'm afraid as I doubt MVC will every get hardware accelerated in LAV.

If custom modes used to work for you, running DDU usually solves these issues. I know you did a fresh install of the driver, but that isn't always good enough. This has fixed issues for me with custom resolutions twice now.

I am using the latest driver with a working custom mode.
