Thanks 6233638 and yes, it happens both with copy-back and native. The only way I can get hardware accelerated deinterlacing to work with madvr is by setting lav to aggressive or forced and as I said, other decoders, deinterlacing doesn't work at all with madvr.
Edit* I have tried now: Reinstalling Latest AMD drivers for my graphics card. Reinstalling madvr Reinstalling lav Reinstalling mpc Changing deinterlacing preferences in madvr "if in doubt activate deinterlacing". None have worked. Last edited by Dodgexander; 15th January 2013 at 17:39. |

With Intel iGPU (HD3000/4000), the good scaling algo is DXVA2? Or bicubic75+lanczos3AR should be better?
And when select luma scaling to DXVA2, chroma can be set to anything and it'll still use intel's internal algo right? Last edited by Guest; 15th January 2013 at 19:31. Reason: 12 |

Question regarding madvr deinterlacing. I very rarely watched interlaced content. When i do it is generally ntsc 1080i tv sitcoms. Should i have madvr autodetect for deinterlacing or force film mode? It seems film mode would be used for most content but im unaware of any way to know when to switch to video which makes me think auto detection would be best.

Therefore, leaving it on auto is usually the best thing to do: You can check whether deinterlacing has been turned on for a particular video by pressing CTRL + ALT + SHIFT + D.

I tried Cyberlinks decoder and deinterlacing works fine, so for LAV it needs to be aggressive, for microsoft or ffdshow dxva deinterlacing doesn't work at all.
Basically any decoder using the controls from the AMD Driver does not work. |

Film mode removes pulldown from telecined content.

The question is whether madVR is too dark or whether EVR is too bright. Please make sure the media player color controls are set to neutral. Then please double check the GPU driver control panel options for video. They should usually be set to "application decides" (or something like that). Finally, try switching madVR output levels to see whether switching to TV or PC levels makes the image look correctly. And of course make sure that what EVR gives you is *really* the correct brightness. Quote:

Not that I know of. Of course using a lower GPU queue size in madVR saves GPU RAM. Quote:

At some point in the future I plan to add an automatic progressive vs. film vs. video detection to madVR. That should then detect such cases, too, but it could be a while until I get to that... I've no problem at all if you guys want to start an IRC channel. But please don't expect me to join. Quote:

It does. But it's measured with the system clock. Which is usually not perfectly identical to the audio hardware clock. Which is the cause of all the problems... It's still on my list of things to look into. |

You make it sound as if there's exactly only one right result of doing resampling. But that's far from the truth. For audio resampling the same problems apply as for video resampling: Depending on resampling filter characteristics, you get aliasing, ringing or loss of high frequency response. Or all of that.

If you say it like this you might confuse some users. Many people consider telecined content as "interlaced content", too. It's important to be clear. If you say "film mode won't properly deinterlace *native* interlaced content" then I fully agree with you. Quote:

Also, wouldn't that technically be detelecining/IVTC, not deinterlacing?

Can mediainfo or a similar program determine natively interlaced vs telecined? |

No. At least not for hard-telecined content. |

And the point about 0.1% was that the tempo change of this small adjustment should be inaudible (possible artefacts aside). Not that the artefacts, such as they exist, would be less because the adjustment was small. But yeah, talking about precision is dangerous Last edited by Jong; 16th January 2013 at 17:40. |

Video Mode deinterlacing of telecined PAL just results in 50p, even if it would be supposed to only be 25p, so usually we never notice any such problems.
