  Wiggle Expression

  Posted by Jeff Pereira on May 11, 2005 at 7:09 pm

  Hello, I’d like to wiggle a layer, but I’d like the wiggle to gradually increase over time. Is there a way to do this with out breaking the wiggle into smaller sections?

  Thanks,
  J.P

  Set up the amplitude (amp) as a variable, and link it to an animated “expression controls” slider effect in the same layer.

  Apply the expression controls effect, using a slider. Make it visible in the timeline. Apply the wiggle expression with a value for freq, but leave amp as is, and write amp= ; in a line above the expression. With the cursor in the space after the = , pickwhip to the slider.

  Now the amp value is determined by the slider value. Animate the slider value, and the amplitude of the wiggle will follow.

  Wow, that is great.

  And implementing the slider was a snap. Now I can see how it can be done easily.

  Thanks.
