Edit Composition Settings for multiple compositions at once

[Rob5FE3]

I'd love to see functionality added to be able to edit the composition settings of multiple compositions at the same time.

Example of functionality:

- Select multiple compositions

- Right click and select composition settings

- Any settings that are shared across compositions are visible

- Any settings that are different between compositions show a '-', but can still be edited

- Once adjustments are made, any settings that weren't adjusted remain as is to ensure that any differences between compositions are still honoured.

Real-life use case:

I have 30 compositions set up for social 'feed' posts at 1080x1080.

I need to now do 'story' versions of all of these compositions at 1080x1920.

Currently, I have to manually edit the specs of each composition one at a time.

Check out AEScripts.com. Smart Resize is one option. There may be others. 

If you are good at writing scripts, you could write your own.

That's fair, and good advice. However this is intended as a feature request. I'd still like to see this feature implemented out of the box. Is there a way to mark this as not solved?

on god i have a client that gave me 20 scenes to animate but brother wants each comp from 1080p to 4k

and I'm thinking intuitively after effects after all its damn updates should have something as simple as selecting multiple comps to resize, but the fact that they don't, makes me question Adobe's decisions.

Hi, @Portfolio_sc 

While there are third-party scripts that will do multiple Comps at once, File > Scripts > Scale Composition is included with After Effects; however, it needs to be run while the Comp is open.  

So, you can open the 20 Comps, bring up the Scale Composition window by choosing the script, and click through your Comps - setting the New Scale Factor to 2 each time as you click through (or use the Select Next Panel in Frame keyboard shortcut to move through) each Comp Timeline tab.
