There was a question the other day on the After Effects List about tips for successfully shooting greenscreen. A couple good links were suggested (see below), but one that stood out was rotating the video camera vertically. If you’re shooting a person standing, and they’re going to be keyed anyways so you don’t need the extra space horizontally, use the wide part of the camera to capture more vertical resolution. It was also a reminder that shooting greenscreen is difficult even for pros.
Great tips from Jonas Hummelstrand:

and from the After Effects Help section!
More vertical resolution, anyone?
