After Effect – Expressions

I have used wiggle expression (camera position) on the video to add a little more life to the video. The video didn’t look as appealing without the expression so it helped the video to look more lively.

Usual wiggle expression looks like…

wiggle(.3,25)

But for it to start or/and stop at a specific time then it looks like…

timeToStart = 2;
timeToStop = 4;

if ((time > timeToStart) && (time
wiggle(3,25);
}else{
value;
}

…which is what I’ve used. I did not need it to stop at a specific time, I just needed it to start wiggling randomly from 9 seconds and it worked.
