## What it does

Apple's foldable iPhone in 3D, folding open or shut with your screens: the cover shows while it's folded, the inner screen when it opens, and the moving half blurs and darkens toward its edge exactly like the launch film. A screen can be an image, a screen recording, an HTML page the agent writes for you, or a URL, and one picture can span both screens so the folded view continues into the open one. Four presets (`unfold`, `fold`, `loop`, `reveal`) or your own keyframes for the hinge and the camera, Star White or Night Sky, a caption that sits with the phone at any aspect, MP4 at any size or transparent ProRes 4444 / WebM for an edit. Frames are rendered one by one in headless Chrome and piped into ffmpeg, so the same flags always give the same video; a 6 s 1080p clip takes about 20 s. The fold deformation and blur shaders are ported from [jadon7/iphone-duo](https://github.com/jadon7/iphone-duo) (MIT); Apple's AR model is fetched from apple.com on the first run and never bundled.

## Use when

- An iPhone Duo or foldable iPhone mockup video, an app promo on a folding phone
- An unfold reveal, a fold animation or a fold-unfold loop with your own screens
- A transparent phone clip to drop into an edit
- Requests like "айфон дуо", "складной айфон", "анимация складывания", "покажи приложение на iPhone Duo"

## Not for

- Flat phone mockups or screen swipes (use stamp-carousel or apple-notes-video)
- Generated live-action footage of a phone in someone's hands (use varg-ai)

## Install

- Claude Code: `git clone --depth 1 https://github.com/vargHQ/code2video-templates ~/code2video-templates && ln -s ~/code2video-templates/iphone-duo-fold ~/.claude/skills/iphone-duo-fold`

## Example output

https://skills.varg.ai/previews/iphone-duo-fold.mp4 — Rendered with the template itself: bun render.ts --config examples/aurora.json (a generated panorama across both screens; folded, the cover shows the cabin and the clock, unfolding reveals the lake). 1920x1080, 7 s.
