Whats the difference between chroma key and green screen?

Question

I want to buy video editing software from pinnacle but i can't decide between studio plus and studio ultimate. So any suggestions there would be nice.

But my real question is whats the difference between chroma key and green screen? i understand that its a way to add your own background to a video. Both Pinnacle packages have chroma key effects, but only the ultimate one has green screen. What's the difference?

And do I have to buy a special type of green screen for either of these?

Answer 1

The correct term is chroma key, but it's often called green screen or blue screen because they're the most popular colours.  They're the same thing, though.  You don't need a special screen, but it should be as near to a pure green as you can get, and it must be evenly lit.

Personally, I wouldn't use any of the Pinnacle editors - they're too buggy and unstable.  Have a look at Sony's Vegas Movie Studio.  It's not as easy to get started, but give it an hour or so and you can produce great results.
