App Store Preview: its example films and styles →
How it works
- 1Copy the install prompt and paste it into your agent.
- 2Your agent runs mo doctor to check Node.js, FFmpeg and Chrome, and tells you how to install anything missing.
- 3Give it your material. It renders an MP4 on your computer, and you ask for changes in plain words.
Paste into Claude Code, Codex, Cursor or any agent that supports skills.

All it takes
No API keyThis is all it needs
- A website or app
Dependencies
Node.js 22+, FFmpeg, Chrome. No API keys.
Before it starts, your agent runs mo doctor to check Node.js, FFmpeg and Chrome and tells you how to install anything missing; if this skill needs more (such as whisper for captions), its instructions say so.
Example prompt
Use the app-preview-director skill to make an App Store preview from the screen recordings in ./recordings for my plant-watering app.
Style prompt (Claude Motion or Opus 5.5)
Make a 25-second App Store preview (886×1920 portrait, 15–30 s, 30 fps) from my screen recordings in [folder] for [who will watch, e.g. people browsing the App Store]. Put the core feature in the first 5 seconds, one short copy line per feature for muted viewers, a hotspot on each tap, plain transitions, one music track; no prices, dates, rankings or calls to action, and disclose [purchases / sign-in]. Use only the screens and lines I give below; don't change a word or number. End on the app name and one line, held for 2 seconds.
Nothing to install: paste this into Claude Motion (Team or Enterprise) or give it to Opus 5.5 for a similar look. The result changes from run to run; the skill works from your own material and renders on your computer.
