• Adobe After Effects Expressions

  Wiggle at only certain volumes on music.

  Hi. I’ve been trying to create an expression for a position’s wiggle but I can’t seem to get it right

  The problem is that I only want it to wiggle at a value of audio keyframes.

  This is what I had (In the expression code box) but it but it only wiggles in the lower right and doesn’t look great.

  And while I’m here, I have another question. I rendered out an mp4. I am trying to speed up the mp4 when the song gets loud and slow it down when it kind of quiet. I don’t want a twitching effect (this is what I keep coming up with)

  All help appreciated.

  s=thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")

  x=value[0];

  if (s < 25) x=value[0];
  else (x=x+s);

  y=value[1];

  if (s < 25) y=value[1];
  else (y=y+s);

  [x, y]
