How To Use Layer Markers To Trigger Animations in After Effects

In this tutorial, learn how to quickly and easily animate objects along a path in after effects.

L = thisLayer;

  KF1 = key(2).time - key(1).time;

  KF2 = key(4).time - key(3).time;

  M1 = L.marker.key(1).time;

  M2 = L.marker.key(2).time;

    if (time < L.marker.key(2).time)

linear(time,M1,M1+KF1,key(1).value,key(2).value)

  else  if (time > L.marker.key(1).time)

    linear(time,M2,M2+KF2,key(3).value,key(4).value)

     else 

  value;
