Miao YangandClaude Fable 5.1 44c43fd99f feat(registry): add 249 seamless image-loop blocks (95 motion families, 1:1)
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.

title: "Loop Pop Grid"

<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-popgrid.mp4" poster="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/loop-popgrid.png" autoPlay muted loop playsInline />
## Install
<InstallCommand command="npx hyperframes add loop-popgrid" item="loop-popgrid" />
That writes one file: `compositions/loop-popgrid.html`.
## Add it to your video
It runs for 8 seconds at 1080×1080. Paste this into your composition:
```html index.html
<div
data-composition-id="loop-popgrid"
data-composition-src="compositions/loop-popgrid.html"
data-start="0"
data-duration="8"
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 |
| --- | --- | --- | --- |
| `mediaFit` | `crop` | `natural`, `crop` | Natural keeps each image's own ratio; Crop fills the card box at the media aspect below. |
| `cropAspectRatio` | `1:1` | `16:9`, `9:16`, `1:1`, `4:5`, `3:2`, `3:4`, `2:3` | Card aspect used when Fit is Crop. |
| `backgroundType` | `gradient` | `gradient`, `color`, `image` | Gradient (start → end colours), flat Colour, or your own Image. |
| `backgroundGradientStart` | `#111111` | color | Top colour of the gradient. |
| `backgroundGradientEnd` | `#444444` | color | Bottom colour of the gradient. |
| `backgroundColor` | `#0b0b0f` | color | Flat colour when Type is Color; also the ground under an Image. |
| `backgroundImage` | `` | image | Cover-fitted background when Type is Image. |
| `blurAmount` | `0` | 0px to 60px, step 1px | Blur on the background image, px. |
| `backgroundGradientNoise` | `0` | 0% to 100%, step 1% | Film-grain overlay strength. |
| `backgroundOpacity` | `1` | 0 to 1, step 0.05 | Opacity of the whole background layer (0 = transparent ground). |
| `borderRadius` | `32` | 0px to 200px, step 1px | Card corner radius in px at 1080. |
| `padding` | `6` | 0px to 100px, step 1px | Padding (engine parameter; see the block header comment). |
| `gap` | `3` | 0px to 10px, step 0.1px | Spacing between cards. |
| `visible` | `62` | 0 to 124, step 1 | Visible (engine parameter; see the block header comment). |
