  Help with expression tied to Audio Keyframes

  Posted by Alturo Nguyen on October 5, 2005 at 8:05 pm

  Goal, tie the position of a layer to the “Audio Amplitude” Layer (keyframes from audio data)

  Getting “expression result must be of dimension 2, not 1” error
  …Figured needed to change min/max stuff to (x,y) type of thingy…still didn’t work
  *******************************************
  minAudio = 0;
  maxAudio = 25;
  minPosition= -1; //Tried this>> maxPosition= (1,1);
  maxPosition= 1; //maxPosition= (1, 1);

  audio=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)
  linear(audio,minAudio,maxAudio,minPosition,maxPosition)
  *******************************************

  still no go

  Thank you

  Your minPosition and maxPosition variables need to be two dimensions, like this:

  minPosition = [0,0];
  maxPosition = [100,100];

  They could be any x and y values, they just need to be in the brackets.
