Changing Keyframe Interpolation 131

P
Depending on your playhead location, the value for the Transform.
Rotation.Z parameter may differ from the preceding figure.

By default, the Keyframe Editor displays all animated parameters for selected
layers or groups, as indicated by the presence of the word Animated in the Show
Curve Set pop-up menu in the Keyframe Editor. Motion will include all “channels”
for the parameter (for example, x, y, and z) even if not all the channels are animated.
On the right side of the window, a pink line connects two diamonds. The diamonds
are the keyframes, and the line is the keyframe curve. The curve is straight because the
default interpolation for rotation is linear, meaning that the rotation value changes
at a constant rate. You can change the interpolation in the Animation pop-up menu,
which appears as a downward facing arrow in the parameter column to the right of
the keyframe icon when you place your pointer over it.
NOTE

The Animation pop-up menu in the Keyframe Editor is similar to the
Animation pop-up menu in the Inspector, but it contains more options.
2 Start playback, and from the Animation pop-up menu, choose Interpolation.
The submenu includes four interpolation options: Constant, Linear, Bezier, and
Continuous.
3 Choose Bezier.
Bezier interpolation creates smoother, more real-world animation by imitating the
effect of inertia: Objects with mass take some time to get up to speed and to slow to a
stop. Instead of a constant rate of change, the rate of change starts low, increases over
time, and then decreases again.
