  Time Remap Expression

  Posted by Jeremy Wick on February 11, 2014 at 7:43 pm

  I’m working on a Lego, stop motion, music video and I want to create sound waves with Lego bars I created.

  I have a comp that is 11 frames. Each frame has one more brick than the previous – they’re stacked on top of each other to create a bar.

  I have that comp in a separate comp, with the time remap linked to the audio keyframes. The highest value in the song is about 44. I want 44 to equal frame :10 and 0 to equal frame :0. I was messing around with this, but got stuck.

  Has anyone done anything similar to this? My project is 24fps, btw.

  Something like this, probably:

  aud = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
  framesToTime(Math.round(linear(aud,0,44,0,10)));
