What is the difference between chroma key and green screen?

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?

You use a green screen to chroma key a composited video. Chroma key is the process in editing, usually people say ‘green screen’ when they’re shooting.

You can chroma key any color – just most video people use green or blue. Depends on what your camera likes.

The critical thing to remember when you’re doing green screen shooting is your LIGHTING!! It is very very important to get even lighting on your screen or it’s not going to key properly.

In answer to your question, depending on the price difference and your budget, get the package that does the most things.

And then when you get frustrated when you can’t do all the things you want to do, chuck it all for Premier or Final Cut.
