I've been wondering for a while, and been doing a lot of research on the subject: how does the main menu in minecraft play a "video". As far as i can tell, it's not a .gif, it appears to be a movie. What is it that minecraft does that allows the moving background in the menu? Sorry for the lack of depth... but that's the question! Thanks in advance!
It's just a few chunks of a specifically seeded world viewed through a camera with a blur effect added that is slowly moving. I believe there is a way to change it though that would be another question.
