How do I get the best Chroma Key possible?
First you need a Green Screen. There are many variations of this to select from. Wirecast Chroma Key also supports Blue Screen. To get the optimal Chroma Key you want to have the best lighting setup. Here is one way to light a Chroma Key scene: • The background screen should be lit as evenly as possible and independently of the talent. • Your talent should cast no shadows on the screen. • Your talent should have 3 light sources on them: 1. The main light (place just to the side of the camera – brightest light). This is what you generally think of as “lighting”. 2. The fill light – so talent has no dark areas/shadows (place on other side of camera – dimmer). This is what keeps your talent from having drop-out areas on them. 3. The back light – to light the edges of the talent (place behind talent). This is what cleanly separates the talent from the background.
