  Scale expression

  Posted by Jonny01782 on March 15, 2007 at 12:48 pm

  Hi, sorry if this is on the forum somewhere already but i couldnt find it, Im new to expressions and im a bit stuck! i have converted some audio to key frames and used the pickwhip to link it to the scale. My problem is that i want the width of the object to stay the same but the hight to vary with the music. does anyone know an expression that will do this?

  It should look something like this:

  minScale = 30;
  mult = 3;
  s = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
  [value[0],s*mult + minScale]
