The beaming out of a disintegrating captain's yacht was scripted but I don't know that anything was really shot. I interviewed the VFX guys at SBS just a few weeks prior to release when they were about to tackle their end of the reshoots for the new ending, and at least one of the guys there mentioned how disappointed they were about the Data beaming out of the distintegrating yacht thing falling out VERY early. They might not even have done animatics for it, though I imagine somebody at Paramount would have storyboarded it during preproduction.
