time variations between 2 keyframes
Hi!
I have this setup:
a: a null called “control” with a slider called “grow”
b: 800 shape layers with trim
So I’m sure it’s possible, but I couldn’t find out how:
I have 2 keyframes in the slider (from 5 to 80). And the end trim value of the 800 layers linked to the “grow” slider inside the null.
I wonder if one of these 2 options could be done:
a) all layers start at the first keyframe and end at the 2nd keyframe but in the middle the speed of each layer is not the same (like editing the easeIn and Out curves randomly)
b) all layers start at the same time but reach their end value some frames after and before the 2nd keyframeRight now I have the 800 layers with their own end trim values animated with no main controller, but automate this would be really great… (as side note, there are a lot of other layers between them, so “following the leader” with index-1 is not possible (or maybe yes?)
thanks!

Something like this might work:
range = 1; // plus or minus 1 second
s = thisComp.layer("control").effect("grow")("Slider");
if (s.numKeys > 1){
seedRandom(index,true);
d = random(-range,range);
ease(time,s.key(1).time,s.key(2).time+d,s.key(1).value,s.key(2).value);
}else
value
Adjust range to get the timing you want.

awesome! thanks!
uhm…is it possible to get the range in frames instead of seconds?

Like this:
range = 10; // plus or minus 10 frames
s = thisComp.layer("control").effect("grow")("Slider");
if (s.numKeys > 1){
seedRandom(index,true);
d = framesToTime(random(-range,range));
ease(time,s.key(1).time,s.key(2).time+d,s.key(1).value,s.key(2).value);
}else
value
