Finally found a method I’m pleased with regarding motion. In the words of Spielberg “I could still see the jerk”.

Involves QTGMC to produce a 60p copy, finding a decent setting on MultiDecimate and then go through each shot frame by frame to remove remaining duplicates. I compare it to a IVTC’d copy of the lower quality DVD-R to make sure the frame match is dead-on. Thankfully these tv-only deleted scenes are short, so I don’t have to go insane doing manual removal. I will hopefully have a test copy in a week or so.
