wiggle expression-1

Hi,

Wiggle expression needs frequency and amplitude. I understand Frequency. But Amplitude is giving me trouble.

X position of a circle is 540 (1080x 1080 comp) . Just in the middle. so If I write in X position wiggle (2,200) that means am telling AE move the circle twice every second and offest will be 200 from original value right? in that case the position range is 540-200 =340 and 540+200= 740. right? So range is fixed. from 340 to 740.

then why does it move beyond 740? it touches 758!! why?

what am missing here?

The amplitude is an approximate, not absolute maximum. It's not uncommon to see peak values 25% (or more) higher than the specified amplitude.

Thank you so much.

if it's critical that the amplitude not exceed a maximum value, you can tie it to a slider and adjust it until it fits within your limits, or change the random seed to get a completely different waveform, like this:

seedRandom(1101,true);
wiggle(2,200);
