Cools man, Have a go using a photo as an image plane, setting up floors to match the persp of the camera youre rendering from and then animate an object this way.

P.S You need to know the focal length of the camera and put this into the camera attributes for the objects havet he same focal/distance properties of the camera.

You can then sort of take the same principles onto footage but its a bit more complex as your gonna need to track the camera as well as knowing all its specs.

What did you learn in Lightwave?
