Yes, the entire movie was cut using subclips made from one original clip. A handful of clips seems to be correct, but 90% seem to be referencing the original clip starting at the 01:00:00:00 Timecode.
IE – First shot is from “Scene 3” subclip. In After Effects the footage used for that shot starts at the 1 hour mark from the original “Full Movie” clip…Then the second shot, also from “Scene 3” subclip, goes back to that same spot on the original clip.
Does that make sense?
