I'm working with a retail DVD release of a film that I guess would be classed as a Shot-on-Video movie.
It's NTSC 29.970 FPS, interlaced, bottom field first, and it has no visible combing, only motion interpolation (I think?)
Likely it's baked in already and impossible to reverse, progressive video flagged as BFF. Still I'm curious to hear a 2nd opinion.
The clip I included is a car in motion. It's also very noticeable on rapid motions such as hand gestures and limbs flailing about.

No motion interpolation. The 24p video was telecined to 30i, then blend deinterlaced. Use FixBlendIVTC() and TDecimate() in AviSyth to restore it to 24p.
Code:LWLibavVideoSource("car-clip.mkv") FixBlendIVTC() TDecimate()

Same result (I think) is obtained with SRestore (included in Hybrid AFAIK):
Code:LWLibavVideoSource("car-clip.mkv") SRestore(omode="pp3") TDecimate()
In Hybrid try: Filtering->Avisynth->Reduction-> Tick 'Restore' and 'Decimate after'.Last edited by Sharc; 29th May 2025 at 18:09.

Thanks, it appears to work well.
I adapted these instructions to vapoursynth and got that to work as well.
omode=pp3 was a critical piece I was missing before.
I left the deinterlacer on QTGMC, I trust that was the right thing to do?
