I have a special type of video that appears to flicker heavily once it's been deinterlaced. I can only assume it happens because of that camera filter or whatever. I don't even know what to call it properly.
Either way, whenever a video like that is featured (not always, it's a news report), there's bound to be flickering. Is there any way to mitigate it? I used both "Fast" and the default presets, no difference.

Ah, I was hoping people would download it and deinterlace it on their end. Here's the deinterlaced video, "Fast" preset.
There is a difference in brightness each field (the problem is the source, not QTGMC) - all double rate deinterlacers will show the luminance flicker
You can try various deflicker scripts/plugins - deflicker, reduceflicker etc...
This deflicker approach is from Didee
AVISource("plane.avi").ConvertToYV16(interlaced=true) AssumeTFF().QTGMC(preset="faster" , border=true) o = last sm = o.bicubicresize(360,288) # can be altered, but ~25% of original resolution seems reasonable smm = sm.temporalsoften(1,32,255,24,2).merge(sm,0.25) smm = smm.temporalsoften(2,12,255,20,2) # most important ! o2 = o.mt_makediff(mt_makediff(sm,smm,U=3,V=3).bicubicresize(width(o),height(o),0,0),U=3,V=3)
Says "Not a clip" when I try using your script. Maybe it has something to do with "o"? Also, is it applicable to the whole footage, even scenes without flickering?
