See especially the roof of that stage. The video is interlaced and has 4:2:2 chroma subsampling. After deinterlacing with QTGMC those aliasing artifacts are still noticeable. I think it could be a sampling issue. Any ideas how to get the best result besides using an antialiasing filter like Santiag (I tried TurnRight().Santiag().TurnLeft())? On a side note, should I save the video as 4:2:2 or 4:2:0?

Did you try 'Very Slow' as QTGMC preset? (iirc one of the parameters that changed between 'Slower' and 'Very Slow' helped with that,...)

The problem is the video is way over sharpened. Try something like:
Code:LWLibavVideoSource("sample.mkv") QTGMC(preset="very slow", Sharpness=0.0) Santiag(3,1)

Yeah, applying an additional QTGMC with InputType=3 and more aggressive AA can help a bit, some flickering can also be removed with masked denoising,... question is when the effort is not worth the result anymore

Thanks. But something strange happened: the image became much darker (with or without the Santiag filter). It seems that Very Slow preset triggers that. Do you have any idea why? I'm using the latest Avisynth+ and I installed the latest versions of all required tools for QTGMC.

Possibly an old or conflicting version of masktools2 or mvtools2 . Check your plugins directory and clean it out
You can use avsinfotool to help identify versions -
