Interesting. The smear in the GOUT can be really bad, even more noticeably when put up against the other versions, but then you can see the video noise in those is at rather a high level. The colour is quite different in each, too. The smear-free '93 colouring is making me think of the '92 vhs tape that I grew up watching; it seems very familiar in that way.
By the way, does anyone have any (relatively) high quality footage from the JSC for the 4-eyed stormtrooper and the Mos Eisley sequence that I might be able to obtain? I'm thinking of putting them into a possible edit I have in mind, mainly just to see if I can actually do it, but if it works I might end up using them.
