how to write expression in such case -14 (scale, wiggle)

[Suraiya A]

Hi,

I want the wiggle expression to repeat the bigger scale in a non regular basis, But the wiggle only makes the star bigger once in the entire 30 sec long comp! How should I write the expression so trhat AE can understand what I want. Thank you.

Please guide me.

see? Star only gets bigger once

wiggle() may not be the right tool. What is the affect you're going for, exactly?

I want the star twinkling based on scale. I tried loop out. But that is robotic... Too much repetation and no aesthetic vibe. Then I tried wiggle. I love the reasult. But it makes the star too tiny... Only once it gets bigger 🥺😶

How big it gets depends on the pre-expression value you have it set at. Wiggle (10,10) is only going to increase that value by 10%. So if you have the scale value set to 5%, the max value will be roughly 15%. So you may need to adjust the the pre-expression value as well as the wiggle amplitude to get the range you want. Also, unless you want non-uniform scaling you might want to do something like this:

freq = 10;
amp = 10;
s = wiggle(freq,amp)[0];
[s,s]

yes, yesss, It works now. I increased the amp to 100, now am getting the result I wanted.

Thank you so much.
