release-video

Two outputs per release:

• Recap: a 45-75 s motion video, one scene per shipped feature, vertical (1080x1920) by default.
• Explained demos: one 30-60 s clip per feature, a real recording of the product with step captions, eased zoom on the payoff, and intro/outro cards (1920x1080).

Every frame of the recap is a pure function of time (window.renderAt(t) in scripts/engine.js), so a re-render is identical, renders split across workers, and any single frame can be pulled as a still for review before the full render.

This skill makes motion scenes and composes demos from recordings. It does not cut raw footage of people talking. For narrated takes, founder voice-overs or interviews, use browser-use/video-use, which cuts on word boundaries from a transcript, and drop the recap and demo clips into its folder as B-roll.

Requirements

ffmpeg, Python 3 with playwright, numpy, Pillow, and ELEVENLABS_API_KEY for audio. If Playwright's bundled Chromium doesn't launch, point CHROME_PATH at any Chromium or headless-shell binary.

Rules from review

These came from a real review of the first cut. Each one cost a full re-render when it was missed.
