User Manual

Methods of adjusting the Bezier handles of motion paths:
 Drag any control point to reshape the motion path.
 Drag any Bezier handle to change the shape of the curve.
 Command-drag any Bezier handle to break the tangent between it and the opposite
Bezier handle. When you release the Command key, the two Bezier handles become
locked together again at whatever angle you created.
To eliminate a control point on a motion path, along with its keyframe:
Right-click any control point and choose Delete Keyframe.
To switch a control point between sharp and curved angles:
Right-click any control point and choose Linear (for a sharp angle) or
Smooth (for a curve).
Keyframing in the Timeline
and Curve Editor
If you need to do more complicated keyframe editing than the relatively simple controls of the
Inspector allow, you can use the Keyframe tracks and Curve Editor found in the Timeline. When
one or more clip parameters are keyframed, two small buttons appear at the far right of a clip’s
name bar in the Timeline, a Curve button and a Keyframe button. These buttons let you access
specialized keyframe editors that serve different purposes.
The Keyframe Editor
The Keyframe Editor in the Timeline is the simplest way of exposing all of a clip’s keyframes and
adjusting their timing and interpolation. It’s only available when you’ve already keyframed one
of a clip’s Inspector properties.
To open or close the Keyframe Editor:
 Click a clip’s Keyframe button at the far right of a clip’s name bar.
 Select a clip and choose Clip > Show Keyframe Editor (Command-Shift-C).
The Keyframe track button in the Timeline
appearing on a keyframed clip
The Keyframe Editor exposes one keyframe track for each group of parameters that’s
keyframed. For example, the Composite parameters, Transform parameters, and
Cropping parameters are all encapsulated by group tracks. For example, if you’d added
keyframes to the Zoom and Position parameters, these keyframes all appear within a
single keyframe track labeled Transform, while Opacity adjustments appear on a
second keyframe track for Composite.
