I don't know if this is possible, searched for a bit but didnt find anything. The idea is to use both of the camera's while filming/shooting picture, so eg, you can see yourself on a pip-ish window. A picture explains better than words i guess, so i made a mockup. It should be very awesome if it was possible! (for the ones who dont get the idea, its a guy in a rollercoaster, you can see the coaster track and his face at once)
