Hi,

For a new project, I want to take a video feed, filmed in a greenscreen room, and as you see it, do a color keying, to kill the green and show an alternative picture on the background.

Is there a way to do this with Flash, AS3?

optional question: If a button is clicked, the now new constructed Picture should be saved as a Jpg. Any Idea?

Thanks a lot for you help!
