Tweaking existing expression
I have this expression from one of AE’s animation presets, but I’d like to tweak it:
______________________
rawAmount = effect(“Scale Bounce – random”)(“Chance of Bouncing”);
compareAmount = (50-rawAmount) / 50;
nervousness = effect(“Scale Bounce – random”)(“Bounce Nervousness”) / 20;
targetScale = effect(“Scale Bounce – random”)(“Target Scale Change”);
noiseResult = noise(time * nervousness);
linear(noiseResult, compareAmount, 1, 100, targetScale)
_______________________Right now, it just randomly scales my text layer. What I want to change is: instead of having regular scaling, I’d like it to be abrupt, where with regular keyframes I would say “toggle hold keyframes” I’d like to do it to this expression somehow, since there are no actual keyframes.
thanks.

Do you know the name of the text preset? It looks like it has several sliders for variables for the expression but I con/t locate it to see if I can hack it?

How often do you want it to freeze? Is it periodic? If so, it might be as simple as adding something like this to the top of the expression:
posterizeTime(3);
