Checks and installs everything the demo-video pipeline needs — ffmpeg, Playwright browsers, the Remotion plugin, uvx, and the ElevenLabs key, plus the optional OBS recorder (websocket reachable, able to pause) and Final Cut Pro finish with its Motion templates and MotionVFX mExtension elements — and scaffolds demo/ in the target project. Use before the first demo video on a machine, when any pipeline stage reports missing tooling, when MCP video tools are absent from /mcp, when OBS will not…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Demo pipeline setup
Verify (and, when asked, install) the toolchain for demo videos.
## 1. Check first, always
```bash
bash ${CLAUDE_PLUGIN_ROOT}/scripts/setup.sh
```
This changes nothing. It reports on: node ≥18, ffmpeg/ffprobe, uvx, Playwright browsers, an
importable `playwright` module for the script capture paths, `ELEVENLABS_API_KEY`, whether
the Remotion plugin and agent skills are present, and the two optional pieces: OBS (installed,
Node 22+, `OBS_WEBSOCKET_PASSWORD` set, the websocket answering, pausing possible) and Final
Cut Pro (installed, the newest FCPXML it imports, `xmllint`, the Motion templates ready, and
MotionVFX: how many elements are downloaded, how many are only placeholders, which theme
packs are downloaded).
Show the user the report.
## 2. Confirm before installing
If the user wants missing pieces installed, **show the exact commands first and ask**.
Some of them change state outside this project:
```bash
brew install ffmpeg # system package
brew install uv # system package
npx playwright install chromium # ~150MB download

How to install
mdr add lukaskellerstein/claude-my-marketplace/demo-setup@sha256:e163255c810e11eeThe line at the top of this page pins the label git:20260914.42e89ab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
