README

launch-film

A Claude Code skill for Apple-style product launch films rendered frame by frame in code.

An HTML page paints any moment through `window.__seek(t)`; headless Chrome captures the frames (one process per worker, 4-sample motion blur) and ffmpeg encodes them. Cuts lock to the measured beat grid of a generated score. ElevenLabs makes the music, voiceover and sound effects, Gemini or GPT the art, and speech-to-text checks every voice line, because the agent cannot listen. A still-by-still critique loop keeps the quality up.

Install

npx skills add Dwite/launch-film -g        # with the skills CLI (skills.sh); drop -g for one project
# or
git clone https://github.com/Dwite/launch-film ~/.claude/skills/launch-film

Claude Code picks the skill up in every project (a global install) or in the one project (a project install). Ask for "a launch film for " or run `/launch-film`.

Requirements: Google Chrome (the renderer points at the macOS path; edit `CHROME` in `template/scripts/render.mjs` elsewhere), ffmpeg, Node 18+, Python 3 with Pillow, and [uv](https://docs.astral.sh/uv/). Keys in the environment: `ELEVENLABS_API_KEY` for music, voice, sound effects and speech-to-text; optionally `GEMINI_API_KEY` and `OPENAI_API_KEY` for images.

Start a film

bash ~/.claude/skills/launch-film/new_film.sh ~/films/my-product    # or ./.claude/skills/launch-film/ for a project install
cd ~/films/my-product
node scripts/render.mjs stills 1,4,8,12,18 && python3 scripts/sheet.py review/stills review/sheet.jpg 5 400
node scripts/render.mjs video --fps 60 --sub 4 --shutter 0.5 --workers 12 --out out/master.mp4

The template is a working 20-second film (kinetic title → phone with a pop-out card and a tap → end card). Timing lives in `timeline.json`, which the page and the audio scripts both read, so picture and sound never drift apart.
