Chapter 50 Adjusting Parameters for Keyframed Effects 741
IX
To vary the acceleration of this clip along its motion path, you must first add Bezier
handles to the keyframes you want to adjust (see “Creating Curved Motion Paths Using
Bezier Handles” on page 738). A velocity handle appears as a small purple dot between
the keyframe and the end of the Bezier handle. You can then modify the velocity
handle attached to each Bezier handle for these keyframes.
The velocity of a clip’s motion from one keyframe to the next can be modified by
dragging the velocity handle in and out along the Bezier handle.
To speed up a clip’s motion at the beginning and slow it down as it nears the
next keyframe:
m Drag the velocity handle in toward the selected keyframe.
