jsut go to theater when you finished the level and find the moment you want to capture and push the screenie button

You go to theater and then you go to the clip on like campaign or recent films then you wait till you find the part. When you stop it you can play around with the view and everything and when you want to take the screen shot you press the X button and move over to the camera option. =)
