freq = 1;
decay = 3;

t = time - inPoint;
startVal = [0, 0];
endVal = [50, 50];
dur = 0.1;
if (t < dur){
linear(t, 0, dur, startVal, endVal);
}else{
amp = (endVal - startVal)/dur;
w = freq*Math.PI*2;
endVal +
}

I got a slightly different script that works too.

freq = 1;
decay = 3;

t = time - inPoint;
startVal = [100, 100]; // Adjusted initial scaling
amplitude = 3; // Adjusted amplitude for slight increase and decrease
dur = 1;

// Linear interpolation for continuous scaling
value = startVal[0] + amplitude * Math.sin(freq * Math.PI * 2 * t / dur);
value = [value, value]; // Apply the same scale to both X and Y axes

value;

THANK YOU OMG I'VE BEEN TRYING SO HARD TO MAKE A SMOOTH SCALE BOUNCE BUT KEEP FAILING, THIS HELPED LOADS
you also taught me a little on how to alter expressions as well!

You"re Such a HERO!!
LOVE from Indonesia 💪

Thank you so much, I can change the values, it gives me many results😊

Super effective, thank you for this quick video

Hey, So it's obvious you are a new channel. Just came across you yesterday. Your method of teaching is amazing and efficient. looking forward to all of you future content. keep up the good work.

Thank you for the tutorial! How can I make it bounce out instead of in?

[chessidychess]

thanks for the video! Where can I change the starting time of this function?
I want it to happen in the middle lets say if my whole thing is 10 seconds long, I want to have this bouncy movement start at 5 seconds.
Essentially what I want to do is basically show an image and after around 5 seconds make an animation where the object flies to the side with a bouncy animation and another object flies in at the same time from the other side also with a bouncy animation, giving the feel as if one object is pushing the other to the side.

This here would be the solution to my issue if I knew how to set a different starting time.

Just what I was looking for. Liked and subscribed!

Thanks bro works great but,
how to control the bounce value ?

[seyferf]

is there a way to bounce out when the frames end? means It bounces back from 50/50 to 0/0 kinda, I hope you understand it.

[harcourtshb]

How do you do the effect thats at the start of this video where the time goes from huge to the right size? Been trying to find it for ages!!

[CoreyDeRosa]

Thanks so much for the script! Looks and works great. Easy to customize as well. Liked and subscribed.

[lokey]

worked like a charm... thank you for the fast tutorial! def subscribing!

[muhammadsyuhada]

can i use it to another object beside a typeface?

[bantuyengiao]

Hi! can you help me
i use this in scale of transform effect, but it error in line 1: expression result must be of dimension 1, not 2

[A.DHorrorShow]

I have apply this I got this error please help

After Effects warning: Expression Disabled
Error at line 1 in property 'Scale' of layer 1 (Adeel') in comp 'Comp 1: expression result must be of dimension 2, not 1

how to reverse it to make it dissapear?

[deviantmultimedia]

At 0:23 He's actually hitting Command+V (aka paste) . That makes a world of difference right? No? Why not? You don't have anything to paste? Well I suppose you need someone to come over and do your animation for you too. Look pal, this is a free tutorial. There simply isn't time to include premium details like V's and "Follow the google docs link in the description to copy the expression script" In fact, I don't even have time to fi
