Hi guys. I need to tap into your respective genius.

I'm looking at adding live actors to sets, newsroom style kinda, but not using the Pop Vidoe add-on. I own Sony Vegas and do my final editing there and I wonder is there any other approach anyone knows of aside from using the Pop Video thing, to key out a background.

I haven't tried it yet, but Vegas will export a video of the Alpha channel only, so I wonder if I export two videos, one with the green screen and another with only the alpha channel, would putting the second video in the other box (transparency or whatever, the terminology escapes me at the moment) key out the background?

Thanks for listening. I wanted to ask before trying it.
