Ok... what should I start with?
Well.
Let's start simple.
For a blockhead walking infront of the earth.
You would need Chroma Key, the earth video, and the blockhead walking video INFRONT of a greenscreen, which can be done on the green screen map.
You would do the greenscreen options in Chroma Key and replace the background with the earth video, so it would look as if a blockhead was walking infront of the earth.
Now replace the Earth video with a blender video, and you've got something.
You choose what you want infront and in back. The ordering.
