Keyframes
A keyframe represents an instantaneous state of an image; it can be saved and
recalled for reuse.
Effects
By arranging a number of keyframes on the time axis, and interpolating
between successive keyframes, you can create an effect in which there is a
continuous change from each keyframe to the next.
The following figure shows three keyframes created with a wipe pattern (the
circle) in different positions. This is interpolated to create the effect shown.
You can save the sequence of keyframes representing a single effect in a
register. Then by recalling this register, you can replay the same effect.
For details of keyframe effect registers, see "Regions and Registers" (page
149).
