Question

I'm using a expression shake and I'm getting this error:

This is the code

n = 0;

if (numKeys > 0){

n = nearestKey(time).index;

if (key(n).time > time){

n--;

}

}

if (n == 0){

t = 0;

}else{

t = time - key(n).time;

}

 

if (n > 0){

v = velocityAtTime(key(n).time - thisComp.frameDuration/10);

amp = .1;

freq =3.1;

decay = 7;

value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);

}else{

value;

}

How long does the comp run beyond the last keyframe? You might need to replace this line:

value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);

with this:

value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(Math.min(decay*t,10));
