• Light people evenly with no shadows. A fill light is very important. An office white
board may be helpful in accomplishing this.
Good Camera
You should get reasonable quality out of most cameras on the market today. Wirecast
has been tested with a low-end DV camera to verify the quality of its Chroma Keying
system. However, the better the camera the better the keying.
If you use a cheap USB Web-cam, it may not give you enough source quality to get a
reasonably good key. But if you have excellent lighting, an iSight camera works well.
3CCD is better than 1CCD. If you have the choice, a PAL camera is better than NTSC, due
to how data is captured internally.
High Quality Video
If you are keying video from disk and not capturing it live, make sure the High Quality
Video option is checked in the Advanced Preferences Panel. This forces Wirecast to
decode the video from disk in the best quality possible, giving the Chroma Key the best
data possible for keying. Wirecast warns you if High Quality Video is turned off when
you turn on Chroma Keying.
