Apple Motion 2 - Manual (Page 437)

Chapter 6 Keyframes and Curves 437
To paste keyframes:
1 Select the destination parameter in the parameter list.
2 Place the playhead at the point in time where you want the keyframes to begin.
3 Choose Edit > Paste (or press Command+V).
Pasted keyframes may not make an identical-looking curve to the original if the
parameter scales are different.
Modifying Curves
Perhaps the most powerful and valuable feature that the Keyframe Editor offers is the
ability to make changes to the curves between the keyframes. Of course, manipulating
keyframes causes changes in the curves, but Motion gives you tools to control the
interpolation and extrapolation of your parameter values themselves.
By using different preset mathematical algorithms or by using manual controls, you can
dramatically alter the impact of your effects.
When you set the interpolation for a curve, you select the keyframe you want to
modify. The method you choose determines the distribution of values through, into, or
out of the selected keyframe.
To set an interpolation method for a keyframe:
1 Select the keyframe you want to affect.
The keyframe turns white.
2 Control-click the keyframe to display the shortcut menu.
3 Choose an interpolation method from the Interpolation shortcut menu.
