Using keyframe animation
Keyframe animation is a technique that computer artists use to quickly make complex animated sequences. Instead of drawing
every frame of a title scrolling in from top to bottom by hand, an animator simply has to set a starting and ending position for the
animation and let the computer interpolate the intermediate frames. The animation pictured on the right has three keyframes: a
starting, middle, and ending keyframe. More complex animations use more keyframes.
While keyframing motion may be the most obvious use for keyframe animations, just about any parameter of an effect can be
animated with keyframes. Keyframe animation techniques are used in many areas, including transition effects, video effects, event
panning and cropping, generated media, and track motion. You can animate color, brightness, transparency, motion, size,
perspective, and many other parameters with keyframes.
These three frames show the progression
of a title across three keyframes.
