Apply the 3D Picture in Picture keyer, and then rotate the image -90 or 90 degrees as needed.

Someone sent me an iphone clip of scenery. It's supposed to be landscape, but it's in portrait. How do I rotate it 90 degrees? Is there a flag or switch I can tick? I don't want to re-render in Edius if possible.
