I was able to hack this together by using the below thread as an example.

Here’s what I came up with, probably a more elegant way to do this but it worked.

max = thisComp.layer(“control”).effect(“Length”)(“Slider”)
min = 436.5019
t1 = key(1).time
t2 = key(2).time
t3 = key(3).time
t4 = key(4).time
if (time<=t1) min;
if (time>=t2) max;
else if (time>t1 && time=t3) ease(time,t3,t4,max,min);

Just came accross this thread while dealing with this so I wanted to reply in case anyone else was dealing with this. If setting the shadow map rez to 4000 doesn’t quite get rid of the blurriness, you can leave it set on “use comp size” and just make your comp size 8k or more. Then crop your comp by putting it into another comp that is your final output size.
