hyperframes

Write HTML. Render video. Built for agents.

HyperFrames is an open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. Use it locally with the CLI, from AI coding agents with skills, or as the rendering core behind hosted authoring workflows.

Using Claude Code, Codex, Cursor, or another coding agent? Run npx hyperframes skills update once, then ask your agent to make a video.

Quick Start

With an AI coding agent

For Claude Code, install the versioned plugin:

claude plugin marketplace add heygen-com/hyperframes
claude plugin install hyperframes@hyperframes

Enable auto-update for the hyperframes marketplace in /plugin → Marketplaces, then use /hyperframes:hyperframes. See the plugin guide for Copilot, VS Code, Cursor, Gemini CLI, updates, and migration.

For standalone skills (including OpenCode), use:

npx skills add heygen-com/hyperframes

The picker opens with nothing pre-selected — the Core Skills group is all you need; /slideshow, /remotion-to-hyperframes and /figma install on demand. Agents and non-interactive runs should use npx hyperframes skills update instead — it installs exactly the core set, whereas skills add --all installs all 7 published skills. The six repo-internal skills under .claude/skills / .agents/skills are excluded by default. For the full published set use npx hyperframes skills.

skills add resolves the skills.sh registry blob, which can lag main by hours. npx hyperframes skills update installs from the current main, so reach for it when you need the newest copy of a skill.

Try a prompt like:

Using /hyperframes, create a 10-second product intro with a fade-in title, a background video, and subtle background music.

The skills teach agents the HyperFrames production loop: plan the video, write valid HTML, wire seekable animations, add media, lint, preview, and render. They work with Claude Code, Codex, Cursor, Gemini CLI, IBM Bob, and other coding agents that support skills.

Skills

HyperFrames ships 7 skills. Make any video by asking for it; the /hyperframes skill carries the contract and the references (film, captions, overlays, motion, look). Read it first.

For standalone installation, default to the core set (/hyperframes, /hyperframes-cli, /hyperframes-registry, /media-use). npx hyperframes skills update installs exactly that from anywhere; the interactive picker (npx skills add heygen-com/hyperframes) lists it as the "Core Skills" group, nothing pre-selected. The picker is interactive-only — a non-interactive or agent run without --skill installs all 7. Use npx skills add heygen-com/hyperframes --all to install the complete published set deliberately (skips the picker), or npx skills add heygen-com/hyperframes --skill <name> for just one (bare name, no leading /).

Standalone installs stay lean after that: npx hyperframes init keeps the core set fresh (plus whatever is already installed) and never expands a partial install; /figma, /slideshow and /remotion-to-hyperframes install on demand with npx hyperframes skills update <name>. Nothing re-pulls the full set behind your back.

Plugin packages

Plugins bundle the full skill catalog and use their agent's update manager. bun run package:agent-plugin builds the committed portable ZIP, source metadata, and SHA-256 checksum. See the maintainer checklist.

Upload to Codex

Build the upload-ready Codex plugin archive from the committed HEAD version of the manifest, brand assets, and skills:

bun run package:codex-plugin

This writes dist/hyperframes-plugin.zip with a hyperframes/ root folder and fails if the archive exceeds Codex's 100 MB upload limit.

Core set

Skill	Use when
/hyperframes	Read first for any request to make, edit, animate or render a video, motion graphic, captions or overlays with HyperFrames (HTML rendered to video). Holds the render contract and the work loop, and points to the references for format, motion, look, captions, whole films and storyboards.
/hyperframes-cli	The HyperFrames CLI by job — scaffold, check, look at frames, edit the timeline, preview, render locally or in the cloud, publish, project history — plus reading its JSON and recovering from build or render failures.
/hyperframes-registry	About 450 ready-made blocks and components installed as editable source — transitions, overlays, titles, kinetic type, captions, charts, maps, 3D, camera moves. Use before hand-building any named visual; also for hyperframes add and catalog.
/media-use	Get or make any media for a video — music, sound effects, images, icons, logos, voiceover, avatar and generated video, transcripts, cutouts, colour grades and looks — with HeyGen or free local tools, and mix placed audio. Also for footage that looks dark, flat or dull.
