Just added posterizeTime() but works perfectly! Thanks!

That is a good question, I would assume that if anything is visible in the composition viewer, any expressions it is connected to will execute / run. So if Layer 1 position property is linked to Layer 2 position property, which is then linked to a Control Layer’s Slider, and Layer 2 is turned off – the expression that Layer 2 has will still execute because Layer 1 is using it.

You could have a deep web of expressions but none of them will execute unless a layer that is visible is using it.

I hope this makes sense!

1. Create a new shape layer
2. Create a 2-point line with the pen tool
3. click on the shape path in the timeline panel
4. Window>Create Nulls From Paths>Points Follow Nulls
5. Use Tomas Bumbulevičius expression for both null’s positions with the Text Layer as your Source.
-Null 1 should have an expression that positions it always on the left side
-Null 2 should have an expression that positions it always on the RIGHT side
6. Click on the shape path in the timeline panel
7. Window>Create Nulls From Paths>Trace Path
8. Shift + Parent your red shape layer to this new null

this will animate the shape on the x-axis based on the width of the Text. I haven’t done this in a long time but I know it took some experimenting with the expressions. There are ways to add “padding” within the expressions that links to sliders.

I would suggest watching some tutorials and looking more into the sourceRectAtTime() expression.

Don’t know of any way for dynamic link between AE files. I don’t know how your projects are setup but the only thing I can suggest is making all your changes in the overlay AE file, import to desired file, and ALT-Click to replace compositions manually. I know that probably isn’t the answer you were looking for but I hope you are able to figure it out.

Without know how your projects are setup, is there a way to just keep them all in one project file? That would make it more robust for if you need to go back and make changes. Maybe bring in all your other AE files into the one overlay file?

Hope this helps?
