ADOBE AFTER EFFECTS 5.0
User Guide
Two Position keyframes and the interpolated frames in between create a motion path.
You can modify layer properties with or without setting keyframes. If you do not set
keyframes, or if you set only one keyframe, changes you make to the property value
remain in effect for the duration of the layer.
Time-vary stopwatch
Each layer property has a time-vary stopwatch icon ( ) that you click to begin the
animation process. Once the stopwatch is active for a specific property, After Effects
automatically sets new keyframes whenever you change the current time and the property
value. When the stopwatch is inactive, no keyframes are present. If you type a value for a
layer property while the stopwatch is inactive, the value remains in effect for the duration
of the layer.
