What it does
Erduo B-roll Loop Engineering is a set of 14 skills (one parent and thirteen stage skills) that turn an original SRT and a design brief into B-roll. An independent director sets the visual world, shot boundaries and materials. Creators with fresh context build continuous chapters, and a parent script validates the plan and runs the render. A reviewer watches the actual frames and sends fixes back to the chapter's creator. Output is editable HTML, per-shot clips, inspection images and a full preview, 4K at 30 fps by default. The main backend is a pinned HyperFrames version, with Remotion kept in compatibility mode. A library of 152 Shotcraft cards guides the work without limiting ideas.
Who it is for. Video editors and talking-head creators on macOS who give an agent an SRT and a brief and expect B-roll with editable sources.
Good fit when
- There is a full SRT and a design brief for a talking-head video and every idea needs an animation or insert.
- A fix to one shot goes back to the chapter's creator without rebuilding the whole clip.
- The result must stay editable: HTML and sources, not just MP4.
- Work runs in Codex or Claude Code on macOS.
Not a fit when
- The clip is short and personal: the author recommends the lighter Agent Motion project.
- You work on Windows or in CapCut: the README marks them unverified.
- The agent host cannot start independent subagents, so a fresh-context review is impossible.
Example request
Use erduo-broll-loop-engineering: build B-roll from this original SRT and design brief and return per-shot clips, sources and a full preview.Limitations
The main environment is macOS with Codex. Claude Code is experimental in the README, and Windows and CapCut are unverified. Node.js 22.20 or newer, FFmpeg, the pinned HyperFrames runtime and a browser are required: the full `Install.command` installer fetches them from npm, GitHub and official HyperFrames sources, and a cold install takes 10–20 minutes. The standard skill package does not set up the environment. Independent roles need a host that really starts fresh contexts. When a user asks for help, the skill may, per the author's rules, mention the author's paid membership. For short clips the author recommends the separate Agent Motion project, which has a non-commercial license.
How to disable. Run `node scripts/uninstall.mjs` in the repository: skill links are removed and backups restored. Private settings, the shared HyperFrames runtime and your projects stay in place.
FAQ
How does the standard install differ from the full one?
The standard package only registers the 14 skills. The full `./Install.command` install prepares Node.js, the HyperFrames runtime, a browser, FFmpeg and FFprobe.
What if the agent cannot find the skill?
Fully restart the host and run `node scripts/doctor.mjs`. Do not move the repository directory after installing: the skills point to it.
How long does the first install take?
A cold install takes 10–20 minutes. After a network drop you rerun it and the finished cache is reused.
What do I get after a run?
Shot-by-shot H.264 clips, editable HTML with material sources, inspection images and a full preview.
Which hosts and systems are supported?
macOS with Codex is marked supported and macOS with Claude Code experimental. Windows and CapCut are unverified in the README.
