Type "make me a beach sunrise animation that loops from day to night" into Claude, and a few minutes later there is a composition in After Effects with a gradient sky, a sun and moon arcing across it, an ocean, sand, and stars that fade in at night. Real layers, real keyframes, in the project you have open.
That is what an MCP connector does for After Effects. Here is how to set it up with Filmit MCP, what happened when we gave it that exact prompt, and the jobs where it genuinely saves a motion designer time.
What does Claude in After Effects actually do?
It builds inside your comp using After Effects' own objects. MCP, the Model Context Protocol, is the open standard AI apps use to connect to other software. Filmit MCP gives Claude 35 After Effects actions:
- Comps, solids, nulls, adjustment layers, shapes and text
- Text styling and per-character text animators
- Keyframes with real easing, interpolation and motion blur
- Expressions, expression controls and linked properties
- Effects, gradients, masks, track mattes and precomps
- Rendering a frame so Claude can look at what it made
Because it reads the comp before it acts, you can refer to things by name: "the logo layer," "the second text layer." And because the output is ordinary layers, nothing is baked. You can open every keyframe it set.
How do you connect Claude to After Effects?
The setup is the same as in Premiere Pro, and if you have already connected one app, After Effects only needs its switch turned on.
- Install the panel. Filmit Studio is a free app that installs the Filmit panel on Mac or Windows. A free Filmit account is all you need for MCP.
- Turn on MCP. In After Effects, open Window, Extensions, Filmit Studio, go to the MCP tab and flip the switch on.
- Connect Claude. Click Connect next to Claude. The panel copies the connector address and opens Claude. In Claude, go to Settings, Connectors, Add custom connector, name it Filmit, paste
https://mcp.filmit.io/mcp, then Add and Connect. - Sign in with your Filmit account, by email or Google.
- Check it: start a new chat and ask "Are you connected to my After Effects right now?" It should name the version it can see.
Full steps with screenshots are in the Filmit MCP docs.
What happened when we asked for an animation?
The prompt in the video above was one sentence: a beach sunrise animation that loops from a day to night cycle. Claude planned it out loud first: a looping comp with a gradient sky that shifts from sunrise to day to sunset to night, a sun and moon arcing across, ocean and sand, and stars that fade in. Then it built it, action by action, adding gradients, shape layers and keyframes while we watched the comp fill in.
Partway through, one step failed. We told it to continue and it picked up where it left off. The finished comp loops cleanly through day, sunset, night and back.
Is it good animation? It is a clean, readable first build, roughly what a student makes in their first semester of After Effects. The value is not the polish. It is that the structure, the layers, the keyframes, the loop, all exists in a few minutes, named and editable, ready for someone with taste to make it move properly.
Pro Tip: Ask Claude to render a frame at a few points in time and describe what it sees. It checks its own work that way, and it catches things like a layer sitting off screen before you do.
Which After Effects jobs is it actually good for?
Structural, repetitive work, the kind where you know exactly what you want and the hard part is clicking it into existence:
- Lower thirds in bulk. "Build a lower third for Jane Doe, Director, that slides in from the left," then a list of twenty more names.
- Comp scaffolding. A null controlling a group of layers, expression sliders wired to the properties you will animate, precomps named and organized.
- Repetitive keyframing. The same ease-in move on twelve layers, offset by four frames each.
- Expressions you would otherwise look up. A wiggle driven by a slider, a loopOut on a layer, a property linked to another.
The pattern: you get a correct, editable structure fast, then you spend your own time on the part that makes it look designed.
When is a dedicated tool the better choice?
When the result has to be exactly right every time. A text message conversation is a good example. Claude can build one, but each build is a fresh interpretation. ChitChat builds chat animations from a script with code, not AI, so the bubbles, timing and layout come out the same way every time. The only thing you can get wrong is the spelling, and TextPilot checks that.
That is the split we use ourselves: prompt-driven building for one-off structure and exploration, purpose-built tools for jobs that must be consistent across a series. Our roundup of the best After Effects plugins covers more of the second kind, and if you like understanding what Claude writes, expressions explained is a good companion.
What if Filmit Studio is on two computers?
This one surprised us while recording. With Filmit Studio on a Mac and a PC, both running After Effects, Claude started building on the Mac while we were typing on the PC. Both copies can stay connected to your account, and Claude works in the copy you used most recently. If you want to be sure which machine it builds on, switch MCP off in the panel on the computer you are not using.
Where does this leave motion designers?
Our honest take: story-driven motion is still king, and it still needs an animator's light touch. What changes is the setup time. The comp that took twenty minutes of layer creation and keyframe entry before you could start designing can exist before you finish your coffee, built from a sentence, fully editable. That is worth having, and it is free to try.
Getting started
Download Filmit Studio from the Filmit MCP page, flip on MCP in the panel, and connect Claude. It works with a free Filmit account, in After Effects and in Premiere Pro, where it can edit your timeline the same way. Show us what you built in our Discord.
