How to randomize timing for random scale expression
Hi All,
I found the below expression provided by Dan on a much older thread which worked like a charm. Now I would like to figure out how to specify a random frame range as opposed to the scale change happening at regular frame intervals. Thanks!frame = Math.round(time/thisComp.frameDuration);
seed = Math.floor(frame/3);
seedRandom(seed,true);
s = random(50,150);

Like this maybe:
frame = Math.round(time/thisComp.frameDuration);
seed = Math.floor(frame/3);
seedRandom(seed,true);
f = Math.floor(random(0,timeToFrames(thisComp.duration)));
framesToTime(f)Dan

Thanks Dan, unfortunately I can’t get that to work…
This is the original expression I’m working with to change the scale every 15 frames:
frame = Math.round(time/thisComp.frameDuration);
seed = Math.floor(frame/15);
seedRandom(seed,true);
s = random(145,275);
[s,s]Can you tell me exactly how I should be incorporating your added line? This is what I just tried, hoping that it would set the random range between 1 – 30:
frame = Math.round(time/thisComp.frameDuration);
seed = Math.floor(frame/30);
seedRandom(seed,true);
f = Math.floor(random(0,timeToFrames(thisComp.duration)));
framesToTime(f)
s = random(145,275);

Something like this maybe:
minFrames = 1;
maxFrames = 30;
minScale = 145;
maxScale = 275;f = timeToFrames (inPoint);
fCur = timeToFrames(time);
n = 0;while (f <= fCur){
n++;
seedRandom(n, true);
durFrames = Math.floor(random(minFrames,maxFrames));
f += durFrames;
}
seedRandom(n,true);
s = random(minScale,maxScale);

Thanks so much Dan! That worked beautifully.
