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 figure below shows three keyframes created with a wipe pattern (the circle) in different positions. This is interpolated to create the effect shown.

Effect execution
Example of keyframes and effect execution
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 124).
