Ease Both: This method combines Ease In with Ease Out, applying both at once. This option
is available only when you Control-click a keyframe; it is not available in the Animation
pop-up menu.
Convert to Bezier interpolation
Bezier interpolation is the most flexible method of curve generation because it allows manual
modification of the curve. Motion lets you convert any keyframe into a Bezier keyframe.
Convert a keyframe into a Bezier keyframe
m While holding down the Command key, drag the keyframe in the keyframe graph.
Bezier handles appear and your mouse movement controls one of the handles.
Note: Command-clicking a Bezier point resets it to Linear interpolation.
To simultaneously modify the handles for more than one control point, Shift-click to select
multiple points, then adjust the tangent handles. If there are no tangent handles on the point,
drag the point while holding down the Command key.
Adjust tangents of a control point
Do one of the following:
m Hold down the Option key and drag a tangent’s handle to adjust it independently of its other
tangent handle.
m Hold down the Option key while dragging a tangent with broken handles to lock the handles
together again.
m Control-click a tangent’s handle, then choose Link Tangent from the shortcut menu to constrain
one broken tangent to another so that both move together.
m Control-click a tangent’s handle, then choose Align Tangents from the shortcut menu to line
both tangents up again.
