Let Claude write your launch video: agent-driven Remotion scenes
Describe the video, let an agent write the Remotion scene code, and render an exact MP4 on your Mac, AI video from code, no keys, free with ReDock.
You can describe a launch video in a sentence and have an agent write the Remotion scenes for it — then render an exact MP4 on your Mac. This is AI video from code, and the distinction matters: the agent writes React scene code, and Remotion’s renderer draws each frame precisely as that code specifies. Nothing is synthesized or hallucinated. ReDock exposes its whole app as MCP tools on localhost:47200, so Claude, Cursor, or ReDock’s built-in agent can author scenes against a live Remotion project running on the Bun runtime.
What “AI video from code” actually means
There are two very different things people call “AI video.” One is generative synthesis — a model invents pixels from a prompt, and you can’t guarantee your product name is spelled right or your logo is the correct color. The other, which is what happens here, is an agent writing code that a deterministic renderer executes. The AI’s job is drafting scene components; the renderer’s job is drawing them exactly. You get the speed of describing what you want with output that’s precise and on-brand every time. We lay out the full distinction in free AI video with Remotion.
How the agent authors a scene
Because ReDock runs Remotion as a stack and exposes the app over MCP, an agent has real context: it knows the project is running, on which runtime, and can write and revise scene files. The loop looks like this:
- You describe the video. “A 15-second launch video: logo animates in, product name, three feature bullets that appear in sequence, then a call to action with our URL.”
- The agent writes the scenes. It produces React components — timing, text, colors, transitions — as Remotion code.
- The renderer draws it. Remotion walks the frames on the Bun runtime; ReDock shows live frame progress.
- You review and refine. Change a color, slow a transition, fix the wording. Tell the agent, or edit the code yourself, and re-render.
You stay in control because the output is code you can read. If the agent gets the timing wrong, it’s a number you change — not a re-roll of a black box. New to Remotion itself? Start with the Remotion tutorial.
No API keys required
ReDock is a free (alpha) native macOS app that ships a built-in agent and a local-LLM catalog. That means you can have a model write your scenes with no external API calls and no keys — the model runs on your Mac. If you’d rather use Claude Desktop or Claude Code, they connect to the same MCP endpoint; the tools are identical. Either way, setup is in the MCP docs and the built-in agent docs.
A realistic launch-video pass
Say you’re shipping a feature. You tell the agent the beats: title card, a screen-recording placeholder, three benefit lines, and a closing CTA with your .test preview URL. The agent scaffolds a scene per beat and wires them in sequence. You render, watch the frames complete, and notice the second transition is too fast. You say so; the agent adjusts the interpolation. Second render, it’s right. The whole thing lived on your machine, cost nothing to render, and the project is now a template you reuse for the next launch — the batch pattern is in render farm of one.
Because the scenes are data-driven, you can also point the same template at your changelog to spin up demo clips automatically — see auto-generate product demo videos.
FAQ
Is the agent generating the video frames?
No. The agent writes Remotion scene code. Remotion’s renderer draws the frames exactly as the code specifies. This keeps your video precise and on-brand — no synthesized or misspelled content.
Do I need to pay for an AI API?
No. ReDock includes a built-in agent and a local-LLM catalog that runs on your Mac, so you can author scenes with no keys and no cloud calls. Connecting Claude or Cursor is optional.
Can I edit what the agent writes?
Yes, and that’s the point. The output is readable React code. Tweak colors, timing, and text yourself, or ask the agent to revise, then re-render. You own the project.
