I've ripped the footage from TMP and play-edited a few times and it's actually easy to pick up the pace of a lot of sections without resorting to amputation (as most fan edits try), but you have to have some reasonable understanding of cinematography and how things cut together to understand how to do it. I easily shorted the drydock flyaround by something like 30 seconds, and if it wasn't for the fact that so many have memorized every note of the music, most people wouldn't be able to spot the trims.
Wise was correct that that film could easily have been shortened, mostly via "letting the air out" as I like to say. Sharpline's edit only lowered the pressure from 44 to 42 PSI. It should have been 37.
