With Take/Show Curve Snapshot enabled, as you move keyframes in the Keyframe
Editor, the original curve—as it appeared when you took the snapshot—retains its color.
As long as you remain in the Keyframe Editor editing the current set of curves with the
Take/Show Curve Snapshot button enabled, the snapshot curve remains available.
Revert a curve to its most recent snapshot
If, after editing a curve, you want to revert to the snapshot, you can do so from the
Animation menu in the Keyframe Editor.
In the Keyframe Editor in Motion, click the Animation menu for the parameter you want
to revert, then choose Set to Curve Snapshot.
The Animation menu (a down arrow) is hidden until you move the pointer over the right
side of the parameter row.
The curve reverts to the state of its most recent snapshot.
Important: If you leave the Keyframe Editor, or load a different set of curves into the
Keyframe Editor, curve snapshots are taken again, replacing the previous curve snapshots.
Set curve interpolation and extrapolation
Set curve interpolation in Motion
Although you can manually create nearly any curve shape to build the animation you want,
the Keyframe Editor provides tools to control the automatic interpolation of curves—that
is, the computed values between keyframes. Depending on the interpolation method you
choose, you can dramatically alter the shape of animation curves, and therefore the impact
of your effects.
To set the interpolation for a curve, you select the keyframe you want to modify, then
choose a distribution algorithm. For more information about the preset algorithms, see
Curve interpolation methods in Motion.
Set an interpolation method for a keyframe
In Motion, do one of the following:
Control-click a keyframe in the Keyframe Editor, choose Interpolation from the shortcut
menu, then choose a method from the submenu.
Select multiple keyframes, Control-click one of them, choose Interpolation from the
shortcut menu, then choose a method from the submenu.
The interpolation method chosen is applied to the entire selection.
