FWIW, I used to have intermittent black screen problems. The unlikely fix turned out to be returning madVR to default settings with the batch file, then re-entering my settings.
I have no idea why that worked (madshi said it shouldn't), but it did. Last edited by jkauff; 14th March 2016 at 23:44. |

Usually it only crashes the first time I try to play a movie after a reboot. If I start exactly the same film, not doing anything in between, it works. So it looks like an initialisation issue or something. Don't have the time to debug in the dark at the moment.

Thanks for your feedback guys. I was feeling alone :P. I also use NNEDI 32 for Chorma but the tests have shown that it is not related to scaling algorithms. It is more a FSE problem in my case, as it presents different behaviour between 8 and 10 bits.

Hmm. I only get black screens if my computer goes into sleep with a video paused. On wake, the video will play sound with a black screen.
It's probably an entirely different cause, because I use "use a separate rendering device", and that runs into problems if my discreet gpu goes into ulps from sleep and is turned back on. However, I mention it on the off chance this information might lead you towards solving your problems. (@madshi, I'm not asking for a fix for the sleep black screen behavior. The problem very rarely happens and isn't really a bug of madvr anyways) |

I was trying to use MPC-BE but I got black screen in MPC-BE too. This problem has been introduced in recent versions of madvr, I tracked it to 90.13, didn't test 90.12 yet. But I think it needs to be fixed, beacuse it happens in every movie I play, and others are having troubles too. What I have found is not related to sleep pc or gpu driver trouble, it is in fact a problem in FSE recently introduced which wasn't present before, I will try windowed mode and if that works will try to track the latest version where FSE works. Thanks for your comments.

Hi!
So madVR doesn't have profiles as far as I know. But is there a method/trick I can use to change settings quickly? I mean the scaling algorithms in particular. I settled on something that works for me most of the time. But other times it gives me constant frame drops. Such as 60 fps, particularly if image resizing is also involved. PS: A "you get constant framedrops fool" alert might come in handy. I didn't realize a video was 60p because of the framedrops. (It was video game footage without motion blur, so less noticeable) |

i having some micro stuttering when playng 23,976 content
i have i optimus system but nvidia 930m only render the video because the hdmi output from intel hd 5500 the display refresh is 23.97570, its possible to be this 00.00030 diference that causing the stuttering? the best mode for me is fse d3d9, but i really don īt know, d3d11 with present a frame for every v sync changes my display behavior anda the refresh rate goes down a little i tried wasapi from reclock and the exclusive mode from mpc-hc internal audio reclock seens to be better but i still geting some stutering its possible to be a v sync issue? should i disable v sync on nvidia cp? because on intel cp donīt have a option to disable v sync, only app controled and driver controled.. itīs possible that the two drivers are perfoming v sync separately? like v sync are performanced two times one time for each driver? on nvidia cp should i put single display perfomance, multi display perfomance or compability mode? someone could help-me? i really don īt know what do to solve this... i tried everything, even smooth motion on 60 hz 72 hz 75 hz canīt solve this thanks

And this stutter persists, even when you use smooth motion?

I believe there is an issue with the way that level adjustments and gamma corrections are being processed.
I have a few Blu-rays here which have badly encoded levels, resulting in a washed-out image. To be displayed correctly, they need black level and white level adjustments, which I've applied using filename tags. This works fine for full-screen playback, where I do not use any gamma correction. However in windowed mode, I tell madVR that my display's gamma is 2.60 and have it set to use a 1.80 power curve - windowed mode is about clarity for me, not accuracy. When applying this gamma correction, the letterboxing - and the video itself - ends up looking very washed-out again. What should be happening is that the level adjustments are applied first, so that the letterboxing is made black, and then the gamma adjustment is applied - so it should look something like this instead. To create that image, I just displayed the level-corrected screenshot in madVR using my typical windowed mode settings. I thought that something was "off" about the way that the gamma correction behaved for a while now, but these Blu-rays with very badly encoded levels are what prompted me to investigate exactly what was happening.

(I probably should have used the word "preset") Keyboard shortcuts would probably work well if I could sot the same shortcut for multiple actions. (Although it complicates things that anti-ringing only has a toggle) I could also make a .reg file if the settings weren't stored in a binary format in a single registry key. |

You can configure profiles for different types of content.
See here: http://forum.doom9.org/showthread.ph...17#post1271417 Click "scaling algorithms" then click "create profile group" and so on. |

Color formats
Greetings madshi,
thank you for your awesome work on madVR. I have a source video with P010 (YUV 4:2:0 10bit) 16-235 HEVC 5.1 4K 59.94fps and I'm using a GTX 960 & Sony X850C 4K TV. Sony reports the panel has "10bit driving of an 8bit panel (8bit + Hi FRC)" and at least it passed the test @ http://forum.doom9.org/showthread.php?t=172128. I can either select Ycbcr420 with 12bit color or Ycbcr422 with 10&12bit color in the Nvidia control panel @ 59/60Hz. (Ycbcr444 & RGB modes at over 30Hz@4K have 8bit color only.) Therefore, should I use 4:2:0 12bit or 4:2:2 10bit when I watch the video in the FSE mode? Also, should I tick "disable GPU gamma ramps" @ Devices - Calibration and disable dithering @ Rendering - Dithering? Thank you! Last edited by Damie; 17th March 2016 at 03:25. |

Thanks, is this because MadVR's dithering is superior to TV's FRC (frame rate control)? So 10bit should be only used with a native 10bit panel?
Or even then, conversion from 4:2:0 to RGB/4:4:4 yields additional benefits? By the way, the source video has also the BT.2020 color space, but I guess this works fine in 8bit mode too? (Gotta manually enable BT.2020 mode from TV settings, Auto detection is not working). |
