To change the interpolation method for multiple parameters
1 In the parameter list of the Keyframe Editor, Shift-click to select multiple parameters.
2 Click in the fifth column of the Keyframe Editor parameter list to open the Animation
menu, then choose a method from the Interpolation submenu.
The selected interpolation method is applied to all selected curves.
Convert to Bezier
Bezier interpolation is the most flexible, allowing manual modification of the curve. Motion
lets you convert any keyframe into a Bezier keyframe.
To convert a keyframe into a Bezier keyframe
µ
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 tangents. If there are no tangents on the point, drag it
while holding down the Command key.
To adjust tangents of a control point
µ
Hold down the Option key and drag a tangent to adjust it independently of the other.
µ
Hold down the Option key while dragging the handle of a control point with broken
handles to lock them together again.
µ
Control-click a tangent’s handle, then choose Link tangent to constrain one broken
tangent to another so both move together.
µ
Control-click a tangent’s handle, thenchoose Align Tangents to line both tangents up
again.
