Hyperframes Registry Video Editor Agents

HyperFrames Registry

The registry provides reusable blocks and components installable via hyperframes add <name>.

• Blocks — standalone sub-compositions (own dimensions, duration, timeline). Included via data-composition-src in a host composition.
• Components — effect snippets (no own dimensions). Pasted directly into a host composition's HTML.

Quick reference

hyperframes add data-chart              # install a block
hyperframes add grain-overlay           # install a component
hyperframes add shimmer-sweep --dir .   # target a specific project
hyperframes add data-chart --json       # machine-readable output
hyperframes add data-chart --no-clipboard  # skip clipboard (CI/headless)

After install, the CLI prints which files were written and a snippet to paste into your host composition. The snippet is a starting point — you'll need to add data-composition-id (must match the block's internal composition ID), data-start, and data-track-index attributes when wiring blocks.

Note: hyperframes add only works for blocks and components. For examples, use hyperframes init <dir> --example <name> instead.

Install locations

Blocks install to compositions/<name>.html by default. Components install to compositions/components/<name>.html by default.

These paths are configurable in hyperframes.json:

{
  "registry": "https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry",
  "paths": {
    "blocks": "compositions",
    "components": "compositions/components",
    "assets": "assets"
  }
}

See install-locations.md for full details.

Wiring blocks

Blocks are standalone compositions — include them via data-composition-src in your host index.html:

<div
  data-composition-id="data-chart"
  data-composition-src="compositions/data-chart.html"
  data-start="2"
  data-duration="15"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>

Key attributes:

• data-composition-src — path to the block HTML file
• data-composition-id — must match the block's internal ID
• data-start — when the block appears in the host timeline (seconds)
• data-duration — how long the block plays
• data-width / data-height — block canvas dimensions
• data-track-index — layer ordering (higher = in front)

See wiring-blocks.md for full details.

Wiring components

Components are snippets — paste their HTML into your composition's markup, their CSS into your style block, and their JS into your script (if any):

1. Read the installed file (e.g., compositions/components/grain-overlay.html)
2. Copy the HTML elements into your composition's <div data-composition-id="...">
3. Copy the <style> block into your composition's styles
4. Copy any <script> content into your composition's script (before your timeline code)
5. If the component exposes GSAP timeline integration (see the comment block in the snippet), add those calls to your timeline

See wiring-components.md for full details.

Discovery

Browse available items:

# Read the registry manifest
curl -s https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry/registry.json

Each item's registry-item.json contains: name, type, title, description, tags, dimensions (blocks only), duration (blocks only), and file list.

See discovery.md for details on filtering by type and tags.

Contributing a new block or component

To author a NEW registry item (caption style, VFX block, transition, lower third, or a reusable component) and ship it as an upstream PR — not install an existing one — follow the full idea → scaffold → build → validate → preview → ship workflow in contributing.md. Copy-paste starter templates (caption / VFX / component / registry-item.json) are in templates.md.
