Transparent Background

[mdmbud]

I was wondering if someone could post breif steps to getting a transparent background when I export a video using green screen. Once I export the video, I want to convert it into flash, so the greenscreen will be transparent.

For example, will video my dog playing, with a greenscreen in the back. What I will do is make the background transparent, then turn the video file later through flash pro into, into a flash file. Then when I play it as a layer on my site, it will just show my dog playing on the screen with nothing behind him, besides the underlying website.

Thanks!

In effects select the chroma keyer tool - use the colour picker to select the green and adjsut sliders to tweak it and wehey - done!

Thanks for reply. I understand that, but how do I go about making it transparent rather than color? Sorry if this is easy question....
