Smoothing Keyframes
Smoothing a keyframe, or adding Bezier handles to it, makes the change from one
keyframe’s value to the next more gradual by applying a curve instead of a straight line.
To smooth a keyframe:
m Control-click the keyframe, then choose Smooth from the shortcut menu.
You can manipulate the velocity of change that takes place from one keyframe to the
next by adjusting the Bezier handles on the curve.
To change the shape of a Bezier curve:
m Drag the Bezier handle on the side of a keyframe.
To resize one side of a Bezier curve independently of the other:
m Hold down the Shift key as you drag a Bezier handle.
When you release the Shift key, the relative length of the two handles is locked to the
new unequal lengths you set.
To change the angle between one side of a Bezier curve and the other:
m Hold down the Command key as you drag a Bezier handle.
When you release the Command key, the new relative angle of the two handles is
locked to the angle you set.
To change the length and the angle of one Bezier handle independently of the other:
m Hold down the Command and Shift keys as you drag a Bezier handle.
When you release both keys, the new relative angle and length of the two handles you
set are locked.
Choose Smooth from
the shortcut menu.
Hold down the Command key to
change the angle of a handle
independently of the other handle.
Hold down the Command and Shift
keys to change the length and angle
of a handle independently of the
other handle.
