Mastering Marker Triggers: Unlock Dynamic Animation in AE!

A boilerplate expression for triggering specific actions or events at designated markers in your timeline. It’s versatile and can be applied to any animatable property to activate actions at specific points in time.

n=0;
if(marker.numKeys>0) {
n=marker.nearestKey(time).index;
if(marker.key(n).time>time) {
n–;
} if(n==0) {
value;
} else {
t=time-marker.key(n).time; //time since marker
// your expression
frequency = 2; // wiggles per second
amplitude = 40; // amount of pixels to wiggle
secondsToLoop = 2; // time to loop in seconds
// ——–
t = time % secondsToLoop;
wiggle1 = wiggle(frequency, amplitude, 1, 0.5, t);
wiggle2 = wiggle(frequency, amplitude, 1, 0.5, t – secondsToLoop);
x = linear(t, 0, secondsToLoop, wiggle1, wiggle2);
x; }
} else {
value;
