Answers

1.	Warping is a process that deforms a portion of an image.
2.	It is best to break the compositing out of a keying operation when the foreground item within the green screen requires color adjustments or transformations.
3.	When adding elements to a moving image, you could analyze the motion of the moving clip and apply that motion to your elements. Or, you could stabilize the moving clip, combine all your elements, and then destabilize the composite.
