What they said

• Turns Codex, Claude Code or any AI agent (Devin, Cursor, OpenCode, OpenClaw, Antigravity, GitHub Copilot icons shown) into a video editor. Name: OpenFilm. Free, open source, MIT.
• Tell it what you want: cuts the ums, picks shots, adds captions, B-roll, colour, motion graphics, voice and music; product videos, ads, explainers, picture books, lessons, music videos.
• Manual editing: click an element to move, scale, turn, colour; properties panel on the right; works on text, shapes and video; draw a box and tell the agent to fix that region.
• Getting started: paste one line into the agent, then describe the video; the editor opens by itself, film builds piece by piece; stop anytime or edit yourself; export any format (GIF, PNG, ProRes, WebM, MP4, HEVC, Premiere Pro / DaVinci Resolve project, transparent, audio stems, captions, whole project).
• This reel was made with it. Early project, updated constantly ("3 a.m. updates"), "Follow now and you're basically an early investor. For free." (Early Investor Certificate gag.)
• Engagement ask: top comment gets made into a video.

Try this

• Creators and small teams: Try an open-source video agent that works inside a coding agent. Describe the video, let it cut filler, add captions, B-roll and graphics, then refine by hand.
• Workflow: Use manual controls for fine edits, and export the formats your tools need, such as a project file for Premiere Pro or DaVinci Resolve.
• Review the install: Read what a one-line install command does before you run it, and check the repository and licence.
• Cost and quality: The software is free, but agent usage costs money. Test it on a short video first.
• Creators: "Top comment gets made into a video" is a cheap way to invite comments and ideas.
