I’ve got a blog on this – https://www.broadcastgems.com/post/how-to-write-performant-expressions-in-adobe-after-effects-developing-intelligent-bespoke-motion

After Effects processes each Expression on every frame - understanding this and other important bits of information will help you write Expressions that are more performant; leading to better user-experiences for your users and this includes yourself.When developing bespoke Intelligent … Continue reading

Thanks for tidying it up. 👌

I wrote an AE Script to provide a decent level of protection for Expressions – https://broadcastgems.gumroad.com/
It’s called AeXpressions Encrypter
It does name scrambling of your variables. And if you have a complex set up, it will work well. it will work better if you also scramble your Effect Control names.
You may also want to place the source text property in the Essential Graphics Panel and let the user know that is the only place to edit text input.
I write not only complex expressions but they’re also usually with Adaptive and Responsive Features. This means each set up can be quite easily used to create hundreds and even thousands (or more) variations with not too much effort for each variation. So, it’s critical to protect my IP.

I’m not familiar too BUT I would look at using System/Script Prompts to proceed to the next stage.

This Adobe Live video was supposed to provide a solution using the new Null Positional Feature but I can’t understand these two nor did I see all the new features. I could have missed something. Perhaps others may get more mileage –

Nothing wrong with Expressions and sourceRectAtTime() – 200% user error, for sure and x-height is not the answer. If it works, it’s because it got lucky. It’s a ‘maybe/iffy solution’. I’ve seen that website and it offers little to nothing in terms of actual, professional output – lots of supposed solutions not only from this site (which is actually good in other areas – except x-height) but very short on providing professional work samples.
If you want a good and quick solution then look at Adobe Express for this sort of output. Adobe Express and Canva provide really good quality output for this sort of work and they have automated and spreadsheet-linked features for scalable output.

I’ve updated/upgraded the Article. Fixed typos. Added LLM Prompt and its results for search to include non-integer and negative numbers. Lots of useful stuff.

The Original Blog has been updated with lots of good stuff AND it’s on the COW.
More details. Additional Expression to select a single word or phrase with support for search-match based on instancing and partial word match.

The Text Selector Expression is arguably the most elusive Adobe After Effects Feature and yet it’s its most powerful Text Feature – Creative COW
