can someone help me in removing ghosting/blending in this clip ? i dont understand exactly what type of artifact is this. i tried plain qtgmc + srestore and

QTGMC(Preset = "Slower", InputType=0, NoiseProcess=0)
srestore(mode=4, thresh=44)

but cant fix it completely or reduce it to minimum. heres the sample source and encoded clip

I didn't look, but I can immediately recommend not using QTGMC as your detection clip for sretore. The best results come from simpler bobs. However, you can still using the frames generated by QTGMC by running both at the same time like so:

FFmpegSource2("....")
d=TDeint(mode=1, type=2, full=false, tryWeave=true)
QTGMC(Preset = "Slower", InputType=0, NoiseProcess=0)
srestore(frate=23.976, speed=-1, thresh=1, dclip=d, mode=4)

Yes, these are aggressive srestore parameters, so I'd suggest bumping up the thresh value until the filter stops working well. You might want to try mode=-4 also, since sometimes srestore will work better by analyzing the chroma instead of the luma. It's kind of an art using srestore since no one method seems to work best all the time.

I've also had better results sometimes by downscaling the analysis clip with ReduceBy2() after bobbing it.

Here's one strange case I've been trying to fix.

https://drive.google.com/open?id=1oI...PD71KtYKHKyZsp (original clip)
https://drive.google.com/open?id=1O1...dNAplNFP5oUVnw (bobbed clip)

I tried figuring out a pattern with a that bobbed clip and it looks like 4 good frames, 2 blended ones. Then if you look closer, it looks more like 3 good frames and 3 blended ones where the middle one is a real blended mess and the surrounding frames much less so Is it something that cannot be handled by SRestore as the origins seem to be an interlaced clip?
