Convert to Bezier interpolation in Motion
Bezier interpolation—the default keyframe type—is the most flexible method of curve
generation because it allows manual modification of the curve. If you’ve converted Bezier
keyframes to linear keyframes, Motion lets you convert them back to Bezier keyframes.
Convert a linear keyframe into a Bezier keyframe
• In the Keyframe Editor in Motion, Command-drag a keyframe.
Bezier tangent handles appear and your mouse movement controls one of the handles.
Adjust the handle to create a custom curve around the keyframe.
Note: Command-clicking a Bezier keyframe resets it to Linear interpolation.
To simultaneously modify the tangent handles of more than one keyframe point, Shift-click
to select multiple points, then adjust the tangent handles. If there are no tangent handles
on the keyframe point, drag the point while holding down the Command key.
Adjust tangents of a keyframe point
Each Bezier keyframe point has two tangent handles that adjust the angle of curve at the
keyframe. By default, these handles are locked together (moving one moves the other,
creating a uniform curve at the keyframe point). However, you can break the handle to
create separate curve segments on each side of a keyframe point. Doing so lets you create
irregular curves.
