  Randomise keyframe time

  Posted by Susie Blatchford on January 23, 2019 at 11:23 am

  I have around 50 layers each with a dot. I’ve set keyframes to animate them moving into different group arrangements – firstly groups of 10, then into bigger groups of 15, then into groups of 5 etc. Is there a way that I can use expressions to randomise when they move so each layer is moving at a slightly different time? I know I can do this manually but it will take some time with all the layers.

  Thanks!

  Something like this maybe:

  minDelay = 0;
  maxDelay = 1;
  seedRandom(index,true);
  delay = random(minDelay,maxDelay);
  valueAtTime(time-delay)

  You can also use this script for the same purpose.
