Different Environments

Hello -

This is my first post here, so I hope I chose the right place for this question...

I am producing a video for a company who is introducing five families of copiers.

One concept is to have one on-camera host. He is sitting or standing as he addresses the camera.

The background behind him (his environment) continuously changes (from small business to huge IT department, to design firm, etc.) and stays on each one for about 15 seconds. Each environment features a product specialist. As the background changes, he interacts with each product specialist in their specific environment and they discuss the features and benefits of each product family.

This way, he touches on each of the five families in their own environment. The spot would be similar to AT&T's Philawarepraguecago spot. The host would be shot green screen and we'd key the backgrounds individually and use wipes as transitions.

Another concept is to have the host walk into each of these product specialist's environments and he interacts with them there. I was thinking of possibly using fake walls or door frames as transitions into each of the environments. This seems much more complicated.

Does anyone have any experience with a semi-complex shoot like this? I'd like to present these ideas to the client, but I want to make sure I can pull them off.

Thanks so much for any help!
