<video className="w-full aspect-video rounded-xl object-cover bg-zinc-100 dark:bg-zinc-800" src="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/loop-wheelspinbottom.mp4" poster="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/loop-wheelspinbottom.png" autoPlay muted loop playsInline />

## Install

<InstallCommand command="npx hyperframes add loop-wheelspinbottom" item="loop-wheelspinbottom" />

That writes one file: `compositions/loop-wheelspinbottom.html`.

## Add it to your video

It runs for 14 seconds at 1080×1080. Paste this into your composition:

```html index.html
<div
  data-composition-id="loop-wheelspinbottom"
  data-composition-src="compositions/loop-wheelspinbottom.html"
  data-start="0"
  data-duration="14"
  data-track-index="1"
  data-width="1080"
  data-height="1080"
></div>
```

Move it in time with `data-start`. Put it on a different timeline row with
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.

## Variables

Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:

| Variable | Default | Accepts | What it does |
| --- | --- | --- | --- |
