How to change Ellipse size to random number within range on second keyframe?
I have about 100 ellipses. I need them all to grow or shrink in size randomly all within a 50% range. I also need this to happen starting at 6 secs and ending at 8 secs with ease in and out. Ideally they start and end of the motion would be connected to Keyframes. I have scoured the internet trying to find a solution, but cannot figure it out. Any one have any ideas? Thanks!

Hello Louis
this code should work.
Copy it to the scale-property of one of the elipses. Then right-click to the scale-property and chosse “copy expression only”.
Then select all other elipses and ctrl+v.
Hope that helps
Andreas//This takes the markers of the comp
var beginning = thisComp.marker.key(1).time;
var ending = thisComp.marker.key(2).time;var shrinkFrom = 50;
var shrinkTo = 150;seedRandom(index, true);
randomShrinkSize = random(shrinkFrom, shrinkTo);var newScale = linear(time, beginning, ending, 100, randomShrinkSize);
[newScale, newScale]
