For purposes of any video that you wish to produce to market your products or services, you should consider using a green screen for a variety of reasons. In a video we produced for Dimension One Spas, it made more sense to have waterfalls and spas in the background of the CEO than his office. So we interviewed him in his office with a green screen backdrop; with a few quick clicks, the editor keyed out the green and substituted water.
We interviewed a scientist using green screen because the client wanted a background of animated cells. And for a coaxial cable company, we used a green screen for their mascot who “flew” in and out of a coaxial cable. For a wine distributor, we placed wine cellars, vineyards and grapes behind the talent.
The beauty of a green screen is that you can pretty much set it up anywhere, as long as there are at least six feet between the interviewee and the backdrop. In the case of a dancer or a troupe of dancers moving and leaping, you would need to use a studio and have an entire wall and floor painted green. But for a simple interview with the subject placed in a chair, you will not need to rent a studio; you can get away with smaller quarters.
