  Expression help

  Posted by Dan Schaffner on April 10, 2006 at 3:04 pm

  I’m using an expression that links the scale to audio keyframes. How do I control the expression so that it won’t scale past the layers original size?

  I just used the pick whip to create the expression.

  How high is the scale going now?

  I don’t remember what scale “convert audio” normally uses. But find the highest that your values are going right now, then make your scale expression into
  (current expression)/highest value*100

  Or if you meant to apply a ceiling instead of scaling the whole thing, use
  Math.max(current expression,100)
