Changing effects over timeBy default, when you apply an effect to a layer, the controls you specify do not change for the duration of a layer. However, you can change an effect over time by assigning a keyframe to one of the effect's properties at the time you want a change to happen, and then changing the effect controls at that keyframe. For more information about setting keyframes and creating changes over time, see Setting keyframes. To set a keyframe for an effect: In the Effect Controls window or the Timeline, click the stopwatch next to the effect property for which you want to set a keyframe. |
