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.

<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-deck-7.mp4" poster="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/loop-deck-7.png" autoPlay muted loop playsInline />
## Install
<InstallCommand command="npx hyperframes add loop-deck-7" item="loop-deck-7" />
That writes one file: `compositions/loop-deck-7.html`.
## Add it to your video
It runs for 7 seconds at 1080×1080. Paste this into your composition:
```html index.html
<div
data-composition-id="loop-deck-7"
data-composition-src="compositions/loop-deck-7.html"
data-start="0"
data-duration="7"
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` | `natural` | `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` | `16` | 0px to 200px, step 1px | Card corner radius in px at 1080. |
| `fade` | `0` | 0 to 100, step 1 | Fade (engine parameter; see the block header comment). |
| `cycles` | `1` | 0 to 10, step 0.1 | Number of motion cycles per loop. |
| `delay` | `0` | 0s to 2s, step 0.01s | Hold time between steps, seconds. |
| `direction` | `left` | `up`, `down`, `left`, `right` | Direction of travel. |
| `flipAxis` | `horizontal` | `vertical`, `horizontal` | Flip Axis (engine parameter; see the block header comment). |
| `planeSize` | `330` | 0 to 1000, step 10 | Card size in scene units. |
| `distance` | `860` | 0 to 8260, step 10 | Camera distance from the formation. |
| `perspective` | `100` | 0 to 200, step 1 | Camera focal length: smaller = stronger perspective. |
| `gap` | `0.38` | 0px to 2px, step 0.01px | Spacing between cards. |
| `maxScale` | `1.15` | 0 to 3, step 0.1 | Max Scale (engine parameter; see the block header comment). |
| `tilt` | `0` | -180° to 180°, step 1° | Tilt (engine parameter; see the block header comment). |
| `twoSided` | `on` | `off`, `on` | Two Sided (engine parameter; see the block header comment). |
| `solo` | `off` | `off`, `on` | Solo (engine parameter; see the block header comment). |

// Deck loop family — "Cards flip through in a stacked deck".
// Mechanism (measured on the 512 previews, 2026-09-08): cards sit on a straight belt (vertical for
// direction up/down, horizontal for left/right) with pitch P; every step (loop/(images*cycles),
// 26.25 frames in the 7s/8-image previews) each card advances one slot with an eased progress
// p = 0.25x + 0.75*expoInOut(x) (Deck03 centre-card position, maxerr 0.028) and at the same time
// rotates about its OWN centre by rho(u) = 115deg per slot up to |u|=1, then on to 180deg (flat,
// back side) by |u|=2 — so the card that just left the centre is seen edge-on at p≈0.75 (Deck03
// f15: p=0.746 by position, h=4px) and then shows its back. The far-from-centre edge of a slot
// card is nearer the camera (Deck01 upper neighbour top 162px / bottom 130px; Deck02 3D
// reconstruction from edge widths: rot 85..90deg at f9-12, 125 at f13, 180 at rest).
// flipAxis vertical -> rotateX, horizontal -> rotateY (independent of the belt axis: Deck04 =
// vertical belt + rotateY gives the tall slivers; Deck06 = horizontal belt + rotateX).
// rotation sign: the leaving card's trailing edge swings toward the camera and over the top, so at
// rest the far-from-centre edge is the near one (Deck01 edge widths 168/127 -> z 903/1194, rho 114deg);
// solo (Deck09 f17: right edge taller) follows the same rule.
// Constants: planeSize = world units at z=distance with f = 1000px*(100/perspective) @1080 (Deck01
// 320 -> 152px@512, Deck03 445*2500/4130 -> 128px, Deck09 500*1000/1090*1.15 -> 250px: all <1%).
// maxScale = centre-card scale, falls linearly to 1 at |u|=1 (Deck02 centre 204 = 177.8*1.15).
// tilt = rotateZ of the centre card only (Deck01 4.5deg, neighbours 0), same 1-|u| falloff.
// twoSided on: 8 images -> 4 two-sided cards (centre-card grey sequence has period 4 in Deck01
// and Deck03; slot +1 and -1 show the same "back" grey for a card); back of card k = image 2k+1.
// fade: 0 -> no dimming at any slot (Deck01 slot1/slot2 greys equal); 30 -> slot1 luma-above-bg
// 0.64 (Deck03 vs Deck01 same faces), slot2 0.60. Modelled as opacity below.
// Guesses/knobs: PITCH — P/planeSize measured 1.022 (D01 gap .29), 1.081 (D03 .44), ~1.3-1.4
// (D06/D08 horizontal belts, neighbours partly cut) — no gap formula fits; used
// P = S*(1+gap)*K, K = 0.78 vertical / 0.97 horizontal. delay = seconds of phase. natural fit =
// contain in S x S. steps per loop = images*cycles. Solo (Deck09 f15-22): the belt still
// translates, only the card nearest the centre (|u|<0.5) is drawn, rotation ~90deg/slot (40deg at
// p=.45); the leaving card rises with its right edge toward the camera, the next one comes from
// below with its left edge toward the camera.
