Change the background alpha color?

How can I change the AE composition background color to not just be a flat color but to use a footage. So when I render it and import it back to AE with ignore alpha checked to see that footage I have chosen.

Sorry, but you can't do that: you can't substitute the background color for a piece of footage. If you put footage in as a background, you will no longer have transparency where you want it.

But you CAN use any kind of footage you want as a background, and before you render turn it off by using the eyeball switch. If you don't turn off the background footage, AE will render it as well.
