It's possible to create a background to follow around the game; and even animated by using several hidden pictures; and representing them as frames.
But what I intend to do is a bit more... advanced. Can you make a movie file be a part of a background of a game? AND it to scroll where you go as well.
I don't think it's possible to put other objects in front of a video file. This could have been fixed in a more recent update but I remember trying it a while ago and couldn't get anything to work.
