Yeah....I'm a bit confused as well. There wouldn't be any wipes at all on the Original-Original negative (meaning: Camera negative).

All the FX, wipes included, would have been done post-production.

Back in the 1920s they did in-camera FX, like iris wipes. But as motion-photography became more sophisticated, that clumsy practice stopped at least in-part for the reason that if you screwed it up, you couldn't undo it.

I'm becoming more and more skeptical about everything that's been fed to us by Lucasfilm, including what source materials they ACTUALLY used for the SEs.

There are wipes and FX on the original negative, it is a completed cut of the film. The way it works is the director chooses which takes he wants evolved and those are then copied to a workprint material, which is what the editor works with. The editor puts the workprint together and that is then sent to a lab, where the same cut is assembled from the original camera negative material under laboratory conditions, including wipes and FX. That is why separate FX elements are (were) usually shot on 65mm or 70mm, because they were then combined in an optical printer to a 35mm film, which became the FX shot's original negative.

Or at least that's how I think it works, I'm sure Zombie could describe bit more accurately...
