Hi Dan

Curious if you do see a possibility to make this evolving fwd<>bwd loop behave like a pendulum. I mean that it speeds up exponentially ( ?) to the middle and slows down in the extremes .

in the box below I post your code for the evolving fwd / bwd loop with the straight speed …

segDur = 13;
segOffset = 2;
totalDur = segDur*2-4;

f = timeToFrames(time);
segNum = Math.floor(f/totalDur);
segPhase = f%totalDur;
if(segPhase < segDur)
framesToTime(segOffset*segNum + segPhase)
else
framesToTime(segOffset*segNum + 2*segDur- segPhase - 2)

sorry for late reply . maybe I can simplify by asking : is there a method to make a layer resistant against keying ? ( the upper layer contains the key , mid layer contains the foreground , and the lower one is the background which should remain complete). screenshots attahched thanks in advance .

all the best

that works brilliant …. thanks so much . when you come to berlin I ll cook a meal for you 😉

btw: would it work as ‘pingpong’ too?
( would run from 0 to 12, from 12reversed to 2 , then from 2 to 14 , back to 4 and so on)

best
