Fine-tuning Animation
You can fine-tune nearly all changes over time using the Speed graph or Velocity graph in
the Timeline window. The Speed graph provides complete information about and control
of the value and rate of change for all spatial values (such as Position) at any frame in a
composition. The Velocity graph provides complete information about and control of the
value and rate of change for all nonspatial values (such as Opacity) at any frame in a
composition.
A. Speed at the current-time marker B. Minimum and maximum speed (not limits)
C. Speed graph D. Speed control
The change of value or speed over time is affected by the following factors:
Time difference The time difference between keyframes in the Timeline window. The
shorter the time interval between keyframes, the more quickly the layer has to change
before reaching the next keyframe value. If the interval is longer, the layer changes more
slowly, since it must make the change over a longer period of time. Use distance to adjust
speed by moving keyframes forward or backward along the timeline.
