madVR - high quality video renderer (GPU assisted)

This doest happen with others renders, only with madvr, and also it happens on every player/setup Ive tested on my house (using madvr of course). The only way to fix this is turning on smooth motion, but I dont like that effect because in 60hz I can see some ghosting on some scenes.

Please help! How can I play 60hz on madvr? (I dont like neither 24hz or 48hz because I totally hate flicker)

Thank you so much.

I've seen bitstreaming with clock correction using ReClock cause judder problems.

If other renderers are fine, it sounds like your madVR settings are at fault. Your rendering stats would be a necessary first step.

This fix very old bug with D3D11@Intel HD4000/HD2500@Win7 - on second (and in more rare cases - on first/only) monitor exit from FS Exclusive (with video played) start massive frame repeats/drops for seconds(5-20) sometimes .
Thanks.

Thanks for the help guys!

I have amd fury. Any crimson driver + pot player 32 bit is instant madvr crash for me. Seem to be fine with mpc hc. So anything I can pinpoint to?

I sent the report using the madvr interface.

seem to be fine with 64bit pot player as well.

I am by no means an expert at diagnosing issues via rendering stats.

With that said, have you tried using processing -> zoom control -> disable image scaling? It looks like your sample video is upscaled slightly, even though it is 1080p, which may cause some issues.

Also, is the present queue filling during playback? And is your average rendering time + present time under the movie frame interval (41.71 ms)? In this case, you should have no dropped frames or presentation glitches during playback.

If you answer yes to all of the above, I wonder if the sharper image is causing artifacts. madVR can produce a very sharp (even oversharpened) image, which can cause motion artifacts. Try disabling all image enhancements and upscaling refinement settings.

Beyond that, what you are seeing might be normal, but I'm not the person to ask.

is there a reason you have changed the flush settings?

You have 25 dropped frames. Maybe the missing frames are what makes motion seems to stutter for you?

Ok I will see and try all of that, thanks... But whats funny is if I enable smooth motion all the jerkiness goes away. What I also tried was changing the dithering options, if I put ordered dithering in the LAV filter the problem goes away in the 720p videos, but it remains in the 1080p ones. It is more obvious in panning scenes like the one in the beginning of The Martian.

Again, thanks, I will try that later today and I will come back with the results.

Yeah, maybe trying to fix the problem days ago I changed some options but forgot to change some of those to the default again.

Thanks!

I think the missing frames error showed up when I paused the video, before there were only one frame missing.

Thanks mate.

this doesn't make any sense because this part of lavfilter isn't used with default settings. did you changed the lavfilter settings too?

think about a screen with default madVR settings.

they usually come from starting and resizing the video and are pointless as long as they don't rise while playback.

You are totally right about the LAV dithering option because after some testing the problem is still there...

Something I see, and might be the problem in here, is the clock deviation... do you guys think that there is the problem? Because when I start the videos (in a panning scene) everything is fluid (with the judder of course) but after the clock deviation shows in the stats the choppy movement also shows in the panning scenes (I cant notice that on other scenes, only if I look for it)

Thanks for the help!

the flush options can cause this problem...
you tried to alter something o gpu control panel?
what gpu are you uing?

[kabal223]

Which are the best flush options?

No, I didnt change anything on my gpu options, its a geforce660

Thanks!

You might have to reset your madVR settings in the installation folder. What audio renderer are you using? Did you try turning bitstreaming on and off?

Sigmoidal light seems to reduce aliasing with Jinc AR.

Sigmoidal light:

So, maybe it can be recommended in general for upscaling?

Default flush options are best now, but you could experiment with changing the GPU/CPU queue to 8/4

It seems you uploaded the same picture twice there.
Even photoshop diff doesn't show any difference between the two. (zero)
It is weird that they have a different filesize though...

You probably rather downloaded the same picture twice.
I checked the image for different pixels (I downloaded them from the image hoster as well), each red pixel differs:

madshi, any plans on adding a "black level correction" checkbox?

I'm about halfway through Peaky Blinders and still have no idea why the blu-ray is so bright. Blacks are almost gray.

Would love an option to correct these mastering issues. DVDs seem to suffer from it more than blu-rays.

Well, after some serious testing the only fix for my problem is using a 58hz refresh rate, now the playback is almost perfect, thank you guys!
