Sample uses for keyframe animation
The following section provides several examples of how keyframe animation can be used with features such as event panning and
cropping, video effects plug-ins, and generated text events.
Animating event panning and cropping
You can combine event panning and cropping tools with keyframe animation to create several special effects. For more information,
see Cropping or zooming a video event on page 266.
Zooming in on a still image
By using keyframe animation in the Pan/Crop plug-in, you can zoom in and out on a still image. In this example, four keyframes are
used to zoom in on a street scene in a photograph and zoom back out again. A generated color gradient event masks the edges of
the image during the zoom to enhance the effect. For more information, see Using generated media on page 307.
