I'm getting some heavy aliasing artifacts on a VHS capture and I can't tell if it's part of the source video, or if the artifacts are being introduced by QTGMC. I'm in the process of converting my entire VHS collection, and so far nothing has stood out to me like this, which leads me to believe it's the source.
Sample videos linked below. I'd appreciate any insight offered.
Raw capture:

Processed with Avisynth:

Script:
Code:SetMemoryMax(1200) SetMTMode(3, 6) FFmpegSource2("R:\vid.avi", atrack=1) SetMTMode(2) ConvertToYV12(interlaced=true) AssumeTFF QTGMC(Preset="Very Slow", SourceMatch=3, Lossless=2, MatchEnhance=0.75, Sharpness=0.1, EdiThreads=3) #LanczosResize(640,480)

Even with a clean source you will have problems with very thin ~horizontal lines in motion.

Understood. Will keep the unprocessed files for archival and future tweaks if necessary.
Cheers.
