Using filter tracks

You can use filters in a movie to create special effects, such as changing the color of a video track or blending two video tracks together. You can also use filters to create transition effects between tracks, such as having one video image cross fade over another video image. You can also specify exactly when filters start and end.

A filter track stores the characteristics of a filter and its target video. There are four different filter tracks you can add to a movie:

• Generic filter tracks generate a cloud, fire, or ripple effect.
• One source filter tracks are applied to one video track only and change the visual presentation of the source track.
• Two source filter tracks, or transitions, fade out one track and fade in another. This filter is applied to two video source tracks. Some examples of transition effects you can select are cross fade, explode, implode, and gradient wipe.
• Three source filter tracks use a track's luminosity to control how two other source tracks blend over each other. This is useful when you want to do real-time animated masking.
