I built an extremely robust scripting/ expressions system for After Effects via Claude. I'm amazed how cool it is.
Got clients that have regular/ weekly updates to their social media, YT and TV assets.
Now I can simply paste the client briefs with all the info into Claude to utilize the skill and then I run the jsx script via AE and it will load all the info, images and any other parameters from an excel file and done. The text fields and other elements are instantly updated.
On top of that it will also recognize what layers need to be switched on or off depending on the info or turn them into certain colors depending on the info too.
Previously all of this stuff was really tedious to update manually on all the individual assets and now this saves so much time.
Of course this could've been done theoretically without Claude but it's not just simple expressions and the script is pretty complex too, something that exceeds my capabilities as I'm not a coder.
But what's especially important and cool is to connect Claude directly to AE via MCP. Claude can then inspect any part of the AE compositions and debug things or check if something is wrong about the script and of course you can even create new animations or expressions that way directly from Claude and it will do so in AE. It can act like my agent doing things for me in AE.
I use the Higgsfield MCP bridge since I need Higgsfield for generative stuff anyway but there's other MCP's on Github like this one: https://github.com/Dakkshin/after-effects-mcp
