••• Offset for Trim Path Start (can be used for creating animationg on paths):
thisProperty.propertyGroup(1).end.valueAtTime(time-thisComp.frameDuration*2)-0.01
••• Fading oscillations (no comments here):
amp = 0.1; freq = 2; decay = 6.0; val = value; 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); try{val+v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t)}catch(e){val}}else val;
