Remote script. The install step runs packages fetched from npm and GitHub, so review what the agent runs before you approve it.

Who it is forA developer or founder who needs a short product or CLI launch video and already works in a coding agent.

The problemMaking a video usually means learning a timeline editor or hiring someone, which slows down a simple launch.

The outcomeA rendered MP4 of a short film written by the agent as web pages, with music if requested.

What you need first

  • Node 22.2 or later and ffmpeg on macOS, Windows or Linux, or the OpenFilm desktop app for macOS or Windows, which includes ffmpeg and the headless browser
  • A coding agent such as Codex or Claude Code, or any coding agent
  • Git, for Studio's saved versions
  • About 100 MB of disk space for the headless Chromium download on the first run
  • Your own API keys in Studio's Settings → Providers, only if you want generated voice, music, images or video

Steps

  1. Install the skill with npx skills add openfilm/openfilm.
  2. Ask your agent for a film, for example: Make a 20-second launch video for my CLI, with music.
  3. Watch the film take shape in Studio, which opens in your browser.
  4. Make changes by hand in Studio or by asking the agent again.
  5. Render the final file with openfilm render.

Prompt for your agent

In the openfilm/openfilm repo, run the skill install, then ask the agent to make a 20-second launch video for <product>. Expect a film folder with a film.html that opens in Studio and renders to an MP4. Verify by running `openfilm look` on the film and confirming it reports no page errors, missing fonts or missing sound files.

Caveat. Generated voice, music, images and video need your own keys for services such as ElevenLabs, OpenAI, Google or fal, and the README does not say which of these your agent will pick.
