How
do I make a Video?
Start with this excellent
overview contributed by the
forum Gurus and posted by Steve
(sknis) on the Roxio forums.
How
do I use the Chroma Key feature
to key out backgrounds?
I hope to have a video tutorial
up soon, but for right now, read
though Gary's (ggrussel) discussion,
where he has posted some screen
captures and an explanation: Chroma
Key Help.
