To slow down a clip’s motion at the beginning and speed it up as it nears the
next keyframe:
m Drag the velocity handle away from the selected keyframe.
To add Bezier handles to a keyframe and change the acceleration:
m Control-click a keyframe, then choose an option from the shortcut menu, depending
on the kind of acceleration you want.
 Ease In/Ease Out: Bezier handles are added to the keyframe and the velocity handle is
set for motion to begin slowly and then speed up over time, as the clip moves from
that keyframe to the next one on the motion path.
 Linear: Bezier handles are added to the keyframe and the velocity handle is set to
provide a steady rate of speed as the clip moves from that keyframe to the next one
on the motion path.
Note: Both commands create Bezier handles with the same controls.
Important: The velocity at which clips speed up into or slow down out of keyframed
motion in the Canvas has no effect on the overall speed of the clip’s motion.
Drag away from the
keyframe to slow down
the motion of the clip at
the beginning and then
speed it up as it nears the
next keyframe.
Two commands in the
shortcut menu let you
manipulate acceleration
on a motion path.
