April 6, 2005 at 6:27 amI want the opacity of my layer to randomly change. I wrote: random(70,95)
But now I would like the flickering to occur not so fast. I want it a little slower. Can someone help me out with what I need to enter to slow down the speed of the flickering? Thanks!

April 6, 2005 at 6:38 amTry this:
n=5; //change every 5 frames
seed=Math.floor(time/(this_comp.frame_duration*n))+1;seed_random(seed,true);
random(70,95) -

Since you want to vary the opacity from 70 to 95, set a keyframe for opacity at 82.5 (splits the difference), then add a wiggle expression:
wiggle(5, 12.5)
then adjust the frequency (5) to suit your needs.
It’s a bit different, but eminently tweakable.
