    Hi, I’m new to using expression in AFX and have very little programing experience. I’m trying to animate different mask opacities so that they vary randomly but in smooth and slow way over time.
    I’ve tried the different Random Numbers expressions but they flicker much too fast for the effect I want to achieve. I’m having a hard time time comming up with a solution to this. Can anyone help me slow down the flicker to a smooth random ondulation? Thank you.

    wiggle(.2,50)
    
    (the 50 is assuming you have your opactiy set at 50 before applying the wiggle to generate the full 100%)
    
    if its still too much just keep lowering the .2 

    A wiggle with usually give you a smoother result than a random expression. Try a wiggle that generates at about .2 times a second.
