launch-film

Turn a product idea into a premium, viral-ready launch video — rendered entirely from code.

An agent skill for Claude Code (and any agent that supports SKILL.md). It interviews you, optionally studies the videos and screenshots you love, writes a beat-sheet script and a frame-exact brief, builds the film in a deterministic HTML motion engine, composes an original picture-locked soundtrack, and renders an H.264 MP4 in 9:16, 1:1 or 16:9.

Manual: copy skills/launch-film/ into .claude/skills/ in your project, or into ~/.claude/skills/ to use it everywhere.

Requirements: Node 18+ and ffmpeg. The skill installs Playwright + Chromium and the Inter font into your project on first run. yt-dlp is optional (for inspiration links).

Use

Just ask:

Make a 15 s vertical launch video for my app Orbit — it books a haircut in two taps.

Here's a video I love: https://… — make something with this energy for our product.

or run /launch-film. The skill walks through:

1. Intake: two short rounds of questions (product, format, look, brand, message, UI, sound), with sensible defaults for anything you skip.
2. Inspiration (optional):
   • Videos and links: turned into timestamped contact sheets, a cut list and a tempo estimate the agent reads, then a written breakdown of pacing and motion grammar.
   • Screenshots: mined for palette, type and surface style.
3. Script: a hook → reveal → proof → payoff → CTA beat sheet you approve.
4. Brief: a six-section, frame-exact spec (the "prompt formula"). It has a beat grid, positions, keyframe tables, blur values and an entry and exit for every shot.
5. Build: the film is written against a small motion engine. Every pixel is a pure function of the frame number, blur follows speed, and nothing sits still.
6. Checkpoints: contact sheets are reviewed against a QA checklist, and you see 4 key stills.
7. Soundtrack: an original synthesized track from a cue sheet (tempo, chords, sections, and every SFX tied to a frame), mastered to −14 LUFS / −1 dBTP. It can also sync to a licensed track you own.
8. Render: Playwright captures every frame, which is encoded to H.264 yuv420p + AAC, then verified.

Originality

Inspiration is used for pacing, rhythm and technique. The skill won't clone someone else's video shot-for-shot or reuse third-party logos, characters, footage or music. It designs original marks and objects and composes original music instead. Your own brand assets are always fair game.
