  Make TrapCode Sound Keys choose between 2 value

  Posted by Touhami Aglagal on April 12, 2017 at 5:07 am

  Hello, so I’m using SoundKeys, I use one for scaling my video, works great, and an other one for rotate the video but of course it’s only rotating in one side, how can I say to soundkeys to one time rotate left (-5°) and the other time rotate right (+5°) ? Didn’t found anything on google, or by searching by myself, by the way i’m kinda noob to After Effect, just saying ^^

  Use an ease expression on the rotation property. ease(t, tMin, tMax, value1, value2)

  t is your trapcode soundkeys layer, just pickwhip to it. tMin and tMax are the highest and lowest values of that you want to reference from those numbers. value1 & value2 would be your rotation, in this case -5, 5

  I don’t have trapcode and used convert to audio keyframes, but your expression would look something like this.

  t= thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
ease(t, 0, 40, -5, 5)
