## What it does

Built on [Camera Scan Gate](https://github.com/heygen-com/hyperframes/tree/main/registry/components/camera-scan-gate) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Black-on-white QR (≥300 px on 1080p) on a card with a light border beam; "Scan to try free" beside it; logo small above.

**When:** Event screens, keynotes, TV/CTV spots and any video shown on a big screen.

**Watch out:** Do not flash it for 2 seconds; hold it at least 7–10 s and never animate the code itself.

**Timing:** Card in 0.4 s, code static, hold 7–10 s; border beam loop 3–5 s.

**Also called:** QR end card, scan CTA, QR code outro

### In FFmpeg

```bash
ffmpeg -i film.mp4 -i qr.png -filter_complex "[1]scale=320:-1[q];[0][q]overlay=W-w-120:H-h-120:enable='gte(t,38)'" out.mp4
```

### In HyperFrames

```bash
npx hyperframes add camera-scan-gate
```
Render the QR as a static `<img>` inside a white card; only the frame/beam animates.

### In Remotion

```tsx
// npx shadcn@latest add @magicui/border-beam
<div style={{background:'#fff', padding:24, borderRadius:24}}><Img src={qr} style={{width:320}}/></div>
```

### In CapCut

Overlay the QR PNG at the lower right inside the guides, no animation on the code; add a Text line "Scan to try" with Fade in.
