The distinction eludes me. Literally. I'm not even sure whether you're using a colloquial or a specialized technical lexicon there.
To me, a "video" is a recorded movie with sound, made with a camera, possibly edited. To me, an "animation" is a rather blurry concept, and could mean anything from a talking-paper-clip to a slideshow to a game world generated in realtime. To me, there's no real relationship between the kind of moving graphic thinger and what it's called, except i suppose that a video would probably eat less processor due to not beging generated on-the-fly.
Heh, old people, you gotta laugh, when i started writing code at 19, i never thought i'd live long enough to get old... i think i'm actually less amazed that i'm still fascinated with computing than that i lived through the misspending of my youth.
