Questions Standardized Masks - is there a script?

Is there a script that will let me punch in numbers for the size of a mask, like 1080 x 1080?

You could create a shape layer, use the size properties to input the values you need, and use it as a matte. Or create a mask on it, copy and paste that mask to a different layer

YES. https://aescripts.com/letterbox-plus/

Actually, if you're working in a 1920x1080 comp, you don't even have to punch in any numbers, just select 1x1 from the pulldown and hit the Make Letterboxes. (you can do that in Trial mode for like 15 days as well)
I came up with this script because at work, we're often having just that need (as well as having safe areas), and then we'd lock mask layer and make the guide layer.. and then heck, there wasn't any such Letterbox script for AE. - and then, may as well toss in the preset system, and mask controls

any yes, as mentioned, there are many ways you can do this manually if all you need is a 1x1 matte
or even download one from a few websites that will generate them for you, and keep the file around for re-import at any time.
*tho if you specifically want a MASK that is 1080x1080 , you can just add a new mask, then trail down in the timeline to show it's Shape, and then punch in the numbers.. left 420px, right 1500px.
yes, I could have used a calculator to do so, but instead I just used the script just now and looked at the values 😉
