You know, since I have recreated the crawl, I had to study the original carefully (from the EoD documentary.) After I was done, I superimposed mine over the original, and because mine was so "smooth" compared to the original, it actually made it look fake, rather than film-like.

The other problem is, sometimes the "shake" is in the video - but the letterboxing remains the same - so if one were to align the shaking, you'd either have to crop a few lines of the movie, or suffer with the top/bottom edges wiggling around. I don't know if either solution is really acceptable.

Personally, if there was any scene that I would consider smoothing out, it would be "A long time ago....", because it wouldn't be affected by the letterboxing.
