I am about to render an Animation with a background video and already did it once, but I'm too stupid to remember how I did it, and can't find any useful tutorial how to do it. So I set the Video as Background "Image", turned on Paper Sky in the "World"-Section and created a Texture with the Video, so what did I forget? When I render it, there's only an image of it in the background but it's not moving.
Can you help me?
