You've eclipsed my knowledge of post-production techniques of the period there, jefferiestubes8
, so I'll defer to you. I'm drawing on my own editing experience (in Final Cut from 16mm, DV, and HDV sources), Walter Murch's book on the subject called In the Blink of an Eye
, and the link I posted a page or two back.
Nevertheless, I'll still stand by the point that professional editors are more than able to find the original shots by hand without error. With or without keycode (which would, of course, make the process a hell of a lot simpler) the discrepencies other posters have worried about won't happen.
