One block per loop variant (loop-<family>[-<n>], 1080x1080), one hand-written engine per family, driven by a single paused GSAP timeline that recomputes every card transform from t. Every engine parameter is exposed through data-composition-variables, grouped like a template editor's panel (Media / Background / Appearance / Animation / Template options), plus image1..N content slots that default to monochrome SVG placeholders. No third-party media ships. Validation: scripts/lint-registry-items.mjs 249/249, oxfmt clean, hyperframes check on one variant per family (95/95), registry.json + docs/catalog pages regenerated by the repo scripts. Previews are rendered locally (720^2) and need the docs-images upload. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

|
||
|
||
## Install
|
||
|
||
<InstallCommand command="npx hyperframes add loop-wheelcarousel" item="loop-wheelcarousel" />
|
||
|
||
That writes one file: `compositions/loop-wheelcarousel.html`.
|
||
|
||
## Add it to your video
|
||
|
||
It runs for 9 seconds at 1080×1080. Paste this into your composition:
|
||
|
||
```html index.html
|
||
<div
|
||
data-composition-id="loop-wheelcarousel"
|
||
data-composition-src="compositions/loop-wheelcarousel.html"
|
||
data-start="0"
|
||
data-duration="9"
|
||
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 |
