Product Demo Video

This is the Codex-skill port of the Claude plugin. There is no slash command, so Codex should drive the workflow explicitly and use the bundled Remotion template under assets/remotion-template/.

Template Setup

• If the target workspace does not already contain a Remotion project, copy assets/remotion-template/ into a working directory such as demo-video/.
• Run npm install in that working directory.
• The template includes scene components, entrypoints, a narration script, and a starter src/storyboard.ts.

Workflow

1. Scan the target project README, docs, manifests, source tree, and any existing screenshots.
2. Ask which features to highlight, preferred length, tone, brand color, and whether specific screenshots should be used.
3. Draft a storyboard using references/scene-catalog.md.
4. Show the storyboard for approval unless the user explicitly asks to skip that checkpoint.
5. Write or update src/storyboard.ts.
6. Generate narration MP3s into public/narration/ by calling scripts/generate-narration.sh once per scene from a small helper script.
7. If ffprobe is available, measure each MP3 and set durationInSeconds to audio length plus roughly 0.8 seconds.
8. Preview with npx remotion studio and render with npx remotion render DemoVideo output/demo.mp4.

Storyboard Rules

• Always start with intro and end with outro.
• Keep most scenes around 8 to 12 seconds.
• Include at least one clearly animated scene such as workflow, comparison, or a dynamic feature.
• Use real code and concrete product details from the target project.
• Keep narration in spoken language, roughly 120 to 150 words per minute.

Notes

• The bundled TTS script supports macOS say, OpenAI TTS, and ElevenLabs.
• If the user already has a Remotion project, copy only the needed components, src/storyboard.ts, or the narration script instead of the entire template.
