## What it does

Built on [iPhone Duo Fold](https://github.com/vargHQ/code2video-templates/tree/main/iphone-duo-fold) by varg (varg), MIT. The write-up and recipes below are varg's.

The device unfolds from closed to open; each half carries its own screen (image, recording or URL).

**When:** Two-sided stories: prompt and result, editor and preview, old and new.

**Watch out:** Do not put unrelated content on the halves; the fold should mean "these two belong together".

**Timing:** Unfold 0.8–1.2 s power2.inOut; hold 2 s.

**Also called:** foldable phone, duo screen, unfold reveal

### In HyperFrames

Use the varg template (HyperFrames-compatible screens): pass each half as an image, video, HTML page or URL.

### In Remotion

```bash
git clone https://github.com/vargHQ/code2video-templates && cd code2video-templates/iphone-duo-fold && bun render.ts --screen app.png
```

### In CapCut

Not native; render the fold with the template and import it as a clip.

### Ready-made components
