Compounding ease() interpolation (source)

You can't control the influence directly, but you can compound the ease such as below.

if (numKeys > 1){
t1 = key(1).time;
t2 = key(2).time;
v1 = [0,540];
v2 = [1080,540];
t = easeOut(time,t1,t2,0,1); // using a normalized value to drive the 2nd ease
easeOut(t,0,1,v1,v2);
}else
value
