The first panel of the wizard lets you display camera and lighting setup tips. If you are not
familiar with setting up your camera and lighting, we recommend that you select the Show
Camera & Lighting Setup Tips check box. Click Next to set the key for your video
presentation.

Position the camera so that it is capturing only the background, and click Auto-Set Key to
calibrate background color.
5.
Position the subject of the video in front of the camera, and click Next.

Remove the blue or green background color by adjusting the Start Level. Move the slider
until most of the blue or green color is keyed out, and only a slight halo of blue or green
surrounds the subject.
7.
Adjust the Desaturation until the remaining green turns magenta, or, if using blue, the halo
turns yellow. Do not desaturate the color so much that it bleeds into the subject.
8.
Adjust the Spill Suppression until the magenta or yellow halo is removed from the image,
but not so much that the green or blue halo returns.
9.
Adjust the transparency so that the subject is solid against the background. Move the
Transparency Level slider so that the subject starts to become transparent against the
background, then back up just past the point when the subject becomes solid.
