* feat(registry): add 25 image carousel blocks (5 families × 5 variants) Five carousel families, each with 5 style variants: - Orbit (1–5): image cards on a spinning 3D Fibonacci sphere - Path (1–5): cards following animated CSS motion paths - Circle (1–5): circular carousel layouts - Vision (1–5): Apple Vision-style spatial presentations - Text Circle (1–5): circular carousels with text overlays All blocks are 1920×1080 at 6s, with 12–24 configurable image slots. Includes catalog preview thumbnails for each block. Co-Authored-By: Jake Moran <jake.moran@heygen.com> * refactor(registry): host carousel block images on the CDN The registry is served straight out of this repository (DEFAULT_REGISTRY_URL points at raw.githubusercontent.com), so every byte a block ships is permanent history. The 25 carousel blocks added 421 JPEGs, 27.7 MiB in a checkout, and made the diff 472 files. Only 23 of those images were distinct: the same 12-24 placeholders were copied into every block. files[] entries gain an optional `url`. When set, the installer fetches the bytes from there instead of joining the registry base. `path` does not change and still says where the file lands relative to the item, so composition HTML, target mirroring and `hyperframes add` behave exactly as before. Keys are content-addressed, so the 396 manifest entries resolve to 23 objects, and a changed image gets a new URL rather than a stale one cached behind `immutable, max-age=31536000`. The catalog preview renderer copies an item's directory and renders it, so it needs the same materialisation step. Without it the preview draws every card blank and reports success, which is worse than failing. Also drops registry/catalog/, 25 hand-made thumbnails referenced by nothing; catalog previews are rendered by CI and served from docs/images/catalog. Verified: all 23 objects return 200 from the CDN with hashes matching their keys; `hyperframes add carousel-orbit-1` against a local registry installs 24 real JPEGs; the preview render produces the album art, and produces blank cards when the fetch step is removed. * style(registry): format the carousel composition HTML `oxfmt --check .` covers the whole tree, and these 25 files were never run through it. The pre-commit hook only formats staged files, so nothing local caught it. * feat(catalog): publish the carousel blocks without republishing their images These 25 blocks had no Catalog page. Every other item in the registry has one, so they shipped invisible: installable by name, unfindable by browsing. Generating them naively undid the change they were added by. The Catalog payload copies an item's assets into docs/public/, which is tracked, so the 396 images this PR just removed came back as 43 MB one directory over — worse than the 3 MB they started as, because each block got its own copy. The copy exists because these compositions assemble `img.src` at run time out of a variable value, so there is no `src="..."` in the markup for the payload's asset scan to resolve. An unpredictable path can only be satisfied by serving every file beside it, which is what `needsOwnDirectory` asks for. An absolute URL needs no directory: the scan already skips any `https:` reference. So for the payload path only, hosted files are left undownloaded and the composition's variable defaults are rewritten to their URLs. The preview renderer still downloads them, because it paints real frames and a missing file is a blank card. The explorer posts every value to the preview frame on mount, including untouched ones, so the page's variable list carries the URLs too. Left as local paths they would have overridden the payload's own defaults and asked the frame for a file that was deliberately never published. Result: 25 pages, 25 payloads, zero bytes of image added. Verified: a spike item declaring no assets at all rendered its 24 covers from the CDN, proving the variable-default path; payload generation for a carousel block now writes no item directory and no shared asset; the preview render still produces the album art. mint validate and mint broken-links pass on the new pages. test:scripts is green. * refactor(catalog): split the hosted-asset step out of prepareProjectDir Two functions rather than one: finding the composition and rewriting its variable defaults are separate jobs, and inlining the mode branch pushed prepareProjectDir past the complexity gate it was already sitting on. Behaviour is unchanged. Re-verified both paths after the split: the payload for a carousel block still writes no item directory and no shared asset, and the preview render still produces the album art. * feat(catalog): give the carousels their own shelf 25 image carousels landed in Showcases and were 53% of it, so the scenes that shelf exists for disappeared underneath them. That is the same shape the 24 editor themes made, and it gets the same fix they got. Keyed on the first tag, which is this file's stated grouping rule, rather than on the name. `screen-flow-carousel` leads with `product-demo` and stays on the shelf that says what it is for; a future carousel that is not named `carousel-*` still lands here. Showcases 47 -> 22, Carousels 25, and no existing item changed shelf. * fix(registry): centre the circle-5 carousel path in its composition Its ring was centred at x=3832.6 in a 3840-wide composition, so it sat on the right edge and most of it fell outside the frame. Only a few cards were ever visible, cropped, with two thirds of the composition empty. The exported path carried absolute coordinates from a layout that was never recentred. Shifting the four vertices by (-1912.597, -4.340) puts the ring on the composition centre. Handles are relative, so only the anchor points move and the shape is unchanged. carousel-text-circle-5 shares the identical path and had the identical fault. The other three circle variants sit within 12% of centre, which reads as authored placement rather than the same bug, so they are left alone. * fix(catalog): rebuild the circle-5 payloads after recentring the path The Catalog preview plays the payload, not the composition on disk, so recentring the source changed nothing a reader sees. The payload still carried the old vertices and the ring still hung off the right edge of the frame. Verified the consumer this time, not just the producer: both payloads now resolve to a path centre of x=1920. The other 23 rebuild byte-identical, so the formatting pass did not reach them. * feat(catalog): promote Carousels to its own section It was a shelf inside Scenes & demos, which is where a scene type belongs by kind but not by weight. At 25 items it is larger than Data & charts (17) and Blocks (13), each of which is already a section holding a single shelf, so the catalog's own precedent puts it one level up. Pulling it out also takes the largest section in the catalog from 120 items to 95, which is the reason the shelf was added in the first place. The two circle-5 pages change because their embedded source block carries the recentred path; nothing else in them moved. --------- Co-authored-by: Jake Moran <jake.moran@heygen.com> Co-authored-by: Miguel Angel Simon Sierra <miguel.sierra@heygen.com>
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio: http://localhost:3002/#project/my-video
# Server: http://localhost:3002
npx hyperframes preview --port 4567
In an interactive terminal, the preview stays attached until you press
Ctrl+C. In a non-interactive shell such as a coding-agent session, the same
command starts a managed preview that survives after the command returns. Use
--background or --foreground to choose explicitly, and manage persistent
previews with --status, --stop, --list, and --kill-all. Add --json to
managed lifecycle commands for machine-readable output. --foreground --json
prints the ready-session envelope once, then remains attached until stopped.
normalize-audio
Measure two local authored audio clips with integrated LUFS and match the target
to the unchanged reference. The command is a dry run unless --write is passed:
npx hyperframes normalize-audio --reference target-audio --target user-audio
npx hyperframes normalize-audio --reference target-audio --target user-audio --write
It updates only the target element's data-volume and refuses unsafe boosts
that exceed Studio's +12 dB ceiling or would clip.
render
Render a composition to MP4. Run from the project directory; the positional
argument is the project directory (not a file), so render the project's
index.html directly, or point at a specific composition file with -c:
npx hyperframes render -o output.mp4
npx hyperframes render -c ./my-composition.html -o output.mp4
publish
Upload a project directory and get a hosted URL that keeps working after the CLI exits. Published projects are private by default:
npx hyperframes publish
npx hyperframes publish ./my-video
npx hyperframes publish --public
npx hyperframes publish --yes
Signed-out publishing returns an authentication-required claim URL; opening it
lets someone sign in and claim the project. Sign in first with
npx hyperframes auth login to publish an owned project you can update. Use
--public to make the claimed project visible to anyone. --yes only skips the
confirmation prompt and does not change visibility.
Signed-in publishers can use --update <url-or-id> to target an existing project
or --space <space-id> to publish into a shared team space. If the requested
project is missing or inaccessible, publishing can create a new project instead;
check the printed URL and status.
See the publish reference for all options, including video proxy settings.
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
