OpenFilm

OpenFilm is an open-source AI video agent and local editor. Add the skill with npx skills add openfilm/openfilm, ask for a short film, and the agent follows a printed manual to build a folder of pages plus film.html. Each shot is a web page with a frame(t) draw contract — canvas, CSS, three.js, footage, audio. Studio runs on your machine in the browser so you can move clips, restyle elements, and save versions the agent will respect. Render is npx openfilm render to MP4 (optional 4K). Media generation uses your own keys for ElevenLabs, fal, OpenAI, Google, and similar. MIT. Node 22.2+ and ffmpeg.

Founders already live in coding agents. Launch clips and product demos still force a separate video stack or a closed generator. OpenFilm keeps the work in the agent you use: it writes the film as HTML and CSS you can read, then Studio lets you fix timing, text, and layout by hand while the agent keeps going on the same files.

Install the skill or run npx -y openfilm@latest so the agent gets the manual. Ask for a 20-second launch video with music, or open Studio yourself with openfilm open. Edit in the browser; overrides write back into the film files. When it looks right, openfilm render exports the MP4 beside film.html. Connect provider keys in Studio only for generated voice, music, images, or stock. Desktop builds for Mac and Windows bundle Studio with chat beside your installed agents.

Not another CapCut clone and not a heavy composition framework first. OpenFilm’s job is agent-native film making: one HTML timeline, one frame function per shot, and a real editor that shares the same files with Codex or Claude Code. Complementary to HyperFrames and OpenMontage when you want the coding agent to author the piece instead of only assembling clips.
