App Promo Reel
Your app's real screens doing real things, cut to a beat, for Reels, TikTok and Shorts.
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
Make an app promo reel for Reels and TikTok from our app's web build: hook with our tagline, show adding an item, the aisle list and swiping an item into the cart, and end on our icon with the sign-up link. Also a square version.
Style prompt (Claude Motion or Opus 5.5)
Make a 16-second 9:16 promo for [who will watch, e.g. home cooks scrolling Reels and TikTok], playing [where, e.g. Reels, TikTok and Shorts]. Use only our app's real screens and the lines below; no mockups, no rankings or numbers we haven't given. Frame one already carries the hook line over our app. Then three features, each a big caption of five words or fewer over our real screens doing one real tap, scroll or swipe, with hard cuts and whips on a 120 bpm beat. Captions stay clear of the platform's top, bottom and right-hand buttons. End: the phone closes into our app icon, which lands with our name, where to get it and our call to action, held 2.5 seconds. A punchy score with a hit on every cut. App: [name and what it does] (e.g. Listling, a shared grocery list) Hook: [our own line, e.g. "Never forget the basil again."] Features: [caption → the real action, e.g. "Add it in one tap → tap a suggested item"] Where to get it and CTA: [e.g. "Free on the web" · "Start a list" · listling.example]
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.
