Live Chroma-Keying

[madness.productions]

I have a presentation to do on Chroma-keying in the next couple of weeks and I'm demonstrating the keylight plugin for Adobe After Effects.

Instead of demonstrating with pre-recorded footage I wanted to use live footage which will allow those interested in viewing the presentation interact with it and see the results live.

I have access to the Adobe Creative Suite 3 and might be willing to pay for an additional plugin if it's not too expensive.

I'm hoping someone will know if Adobe OnLocation or AdobeUltra has these functions. I haven't been able to find these in the creative suite but I know OnLocation should have been bundled with Premiere so I'll ask some questions about that.

So can anyone help me out.
Thanks in advanced

Adobe Ultra should be able to do this, assuming you have the computing power to do it live. I can't recall exactly when Adobe bought the Ultra software, so I am not sure if it made it into CS3 or CS4

Wikipedia seems to say it was bundled with CS3.
I'll check out it's official website to see what it says perhaps I could get a 30-day trial.

I also remember reading a documentation for a After Effects CS3 plugin which processes live keying, I cannot remember what it was called, I'm hoping someone else has come across it. But hopefully Adobe Ultra will do.
