Hi,

So I want to terminate an effect to work exactly at a certain point, but before reaching that very second the effect must continue. Is there any way I can use an expression for this? please help me.

Not sure if this is what you’re asking for, exactly, but try setting a comp marker at your stop time and add this expression to the Turbulent Displace Amount property:

m = thisComp.marker;
val = value;
if (m.numKeys > 0){
  val = time >= m.key(1).time ? 0 : value;
}
val
