Scale precomp with text changing

[animaii]

Hi there,

I made a animation of rectangles and then pre-comp them.

Now I have a text with the pre-comp under the text.

I would like that when I change the text, like Hi to Hello, the pre-comp size scale with text change.

you can do this using sourceRectAtTime expression. just link the appropriate parameters.

Thank you Roei Tzoref,

I tried with this one, but I put the expression on the scale of my pre-comp and liked like as the tutorial but it makes me a huge scaling...

I think it's because I link x and y like in the tutorial, and he use a shape rectangle so it's working but I'm using a pre-comp so in the scale there is no x and y...

Here is my project if you want to help me 🙂

Well I put this :

x=thisComp.layer("Digital Collaboration").sourceRectAtTime().width/10;

y=thisComp.layer("Digital Collaboration").sourceRectAtTime().height;

[x,y]

And the scale of my pre-comp scale less bigger and it's look what I would like.

But I would like it keeps like 30px left and right of my text...

Like my guide layer "Border info"

Add +60 (or whatever number you like) to both x and y.

For further control you could create expression slider controls and then link the + amount to those slider controls.
