The more keyframes you add, the greater the variety of colors you can have. For more onadding key frames see the section on "Using key frame controls" on page188.Working with tracksVideo Editor has three types of tracks you can work with: video,transition, and audio. The video tracks consist of two primary tracks(Va and Vb) and an additional 99 overlay tracks (V1...V99). Between theprimary Va and Vb tracks is the transition (Fx) track, which allows you tocontrol how clips in the Vb track merge with clips in the Va track. Theoverlay tracks are used for performing color keying (blue screening),moving path effects, rolling credits and much more. The audio tracksbehave similarly as the video tracks, with the exception that there is notransition track.
