Re: Linking audio amplitude to PNG sequence?
by Dan Ebberts on Jun 13, 2008 at 4:50:11 pm

You need turn on time-remapping for your PNG sequence and use a time remapping expression something like this:

minAudio = 0;
maxAudio = 15;
maxFrame = 28;

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

f = Math.round(linear(audioLev,minAudio,maxAudio,0,maxFrame));

f*thisComp.frameDuration
