In this clip from Total Premiere, Brian Maffitt gives a tour of Premiere's terrific keying abilities. Starting with an image of toys shot against a blue screen, Brian applies the Transparency command. Setting the Key Type to "Blue Screen" is a no-brainer, but Brian also demonstrates the subtleties of the Threshold and Cutoff parameters. The same technique serves Brian well as he next works with a green screen shot of a toy airplane (yes, you can set the Key Type to "Green Screen" too!) Brian then turns to the Motion Settings in his quest to make the keyed airplane fly across the screen, and demonstrates the necessity of setting an appropriate Fill Color. This clip is a sure cure for the blue screen blues; let Brian show you that with Premiere, it is easy keying green.
