It might also be worth noting that in general I tended to aim for the minimal fix - in this case, applying a hue layer, rather than repainting all the sabres. The sabre blade is not well aligned to the hilt in this scene, as Mark Hamill didn't have a prop blade - this is the sort of thing they really should have fixed for the Special Edition, let alone the DVD. But I guess it isn't as notable as Jawas falling off a Ronto
(and entails a lot more than Photoshopping one frame).
To be fair I did make myself some actions so each frame only took about two seconds
