# Tracking-In Feature Label — effect skill for headlines & callouts

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page.

Wide-spaced letters draw together into a tight, crisp label as the blur clears.

## What it does

Built on [Tracking In](https://github.com/heygen-com/hyperframes/tree/main/registry/components/tracking-in) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

A short label starts with very wide tracking and soft blur, then closes to normal spacing with a tiny spring.

**When:** Feature names, plan names and section labels over UI — quiet and premium.

**Watch out:** Do not use it on paragraphs or long names; tracking changes reflow the whole line.

**Timing:** 0.6–0.9 s, expo.out; letter-spacing from ~0.5 em to 0.

**Also called:** letter-spacing reveal, tracking in, premium label

### In HyperFrames

```bash
npx hyperframes add tracking-in
```
```js
tl.from(".label",{letterSpacing:"0.5em",filter:"blur(6px)",opacity:0,duration:0.8,ease:"expo.out"},0.4);
```

### In Remotion

```tsx
// npx shadcn@latest add @remocn/tracking-in
const p = spring({frame,fps,config:{damping:18,stiffness:120}});
letterSpacing:`${interpolate(p,[0,1],[0.5,0])}em`
```

### In CapCut

Text → Animation In: "Spread in"/"Letter spacing" 0.6–0.8 s.

## More headlines & callouts skills

- [Kicker Over Rising Headline](https://varg.ai/how-to/skills/kicker-headline-rise.md): A small mono kicker fades in, then the headline rises word by word from a soft blur.
- [Rotating Benefit Word](https://varg.ai/how-to/skills/rotating-benefit-word.md): A fixed phrase holds while one word in it cycles through benefits, uses or audiences.
- [Masked Line Reveal](https://varg.ai/how-to/skills/masked-line-reveal.md): Each line slides up out of an invisible slot, so the type looks cut from the frame.
- [Marker on the Key Phrase](https://varg.ai/how-to/skills/marker-highlight-phrase.md): A marker band draws behind the one phrase that matters while the rest of the line stays calm.
- [Strike Old, Write New](https://varg.ai/how-to/skills/strike-and-replace.md): A line strikes through the old way, then the new word takes its place.
- [Clean Lower Third](https://varg.ai/how-to/skills/clean-lower-third.md): Name and role slide in at the lower left on a quiet bar, hold 3–5 s, then wipe out.
