* feat(registry): gooey split block with metaball goo and directional motion blur A dot splits into a three-dot menu through a gooey neck, spins into a swirl mark under shutter motion blur, breaks back into three dots and merges into one. Timing, spacing and eases are measured off a reference recording frame by frame. The motion-blur snippet gains an opt-in `sharp: 0` option that hides the crisp frame-time copy while an element moves, leaving only the shutter average. The default is unchanged; the inlined copies carry the same text. * feat(registry): grow gooey-split blades out of swelling dots * refactor(registry): tidy gooey-split pose code and document sharp 0 limits * fix(registry): hide a sharp 0 motion-blur target by marker, not its visibility Hiding through the element's own visibility fought timelines that write it (autoAlpha): a target faded in after attach stayed hidden at rest. A marker attribute and one !important rule now do the hiding, the default path writes nothing, and a declarative sharp other than 0 or 1 is refused like any other bad option. * fix(registry): smear a motion-blur target that was hidden when blur attached Copies froze the target's computed visibility at attach, so a target entering with autoAlpha never smeared (and vanished entirely under sharp 0). The group now carries the target's current visibility each frame, read with the sharp 0 marker lifted, and a copy keeps a descendant's visibility only where it differs from its parent's. * test(registry): pin a copy keeping a descendant's own visibility * fix(registry): keep a child's own hiding in the smear of a target hidden at attach * refactor(registry): restore a lifted visibility in one call and lift any hidden form * fix(registry): restore a lifted visibility even when copying styles throws * fix(registry): let motion-blur copies hide with a clip that has ended The smear group set an explicit visibility on every moving frame, and copies used to freeze an explicit visible, so an ancestor clip hiding after the last update could not hide them: copies from a 0-4 s sub-composition stayed on screen at 16.4 s. The group now sets a visibility only where the element's differs from its parent's. Also regenerates skills-manifest.json for the motion-blur skill doc.
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
Set HYPERFRAMES_RENDER_DETACHED=1 when starting a render with nohup or
disown so it keeps running after the invoking shell exits.
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
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
