Chroma Key in Premiere CS3?

[MikePizzoff]

Chroma Key is not in Premiere CS3, so I've just been using Color Key. Is Color Key the same thing as Chroma Key or is there a difference (perhaps Chroma is easier)? Also, is there anywhere I can download a plug-in for CS3 in order to get Chroma Key into it, if there happens to be any difference from Color Key. Thanks in advance.

Chroma Key is not in Premiere CS3, There is Chroma Key in Premiere CS3. Are you using a Mac or something?

There is Chroma Key in Premiere CS3. Are you using a Mac or something? Woops, I forgot to mention that I'm on a Mac! I've also realized that Color Key works pretty much exactly the same as any other Chroma Key I've used. I just wish it worked more like Final Cut, where I could click and drag the color-dropper around the image to make sure I get every color I want keyed out, instead of having to create multiple keys for the clip.
