Chapter 16 Changing Clip Speed and Time Remapping 331
II
 Acceleration/deceleration: Finally, the most powerful feature of the time graph is the
ability to adjust the transition in a clip from one speed to another, at whatever
velocity you require. Gradual changes from one speed to another are represented by
curves. For example, a gradual transition from slow motion to fast forward might
look like this:
When you put all this together, you can start to understand what is happening in more
complex time graphs. For example, in the following graph, you can see that the clip
begins by playing in slow forward motion, gradually speeds up, and then goes in
reverse briefly before going back into slow forward motion just before the end of the
clip. Each speed transition is smoothed out by a Bezier keyframe.
For more information on using Bezier handles to smooth keyframes, see “ Smoothing
Keyframes With Bezier Handles ” on page 268. For more information on working in the
keyframe editor of the Timeline, see “ Working With the Timeline Keyframe Editor ” on
page 286.

Tip: The keyframe editor area of the Timeline can be resized vertically, allowing you to
have a more detailed view of the keyframe graph you’re editing. For more information,

Working With the Timeline Keyframe Editor ” on page 286.
