A plugin for writing HTML and rendering it as video with HyperFrames by HeyGen. It supports animated compositions, captions, voiceovers, audio-reactive visuals and website capture.

Use it to create animated videos from HTML, including motion graphics, captions, sound-linked visuals and captured websites.

It lets web-based compositions and related media be rendered into video rather than only viewed as a web page.

hyperframes — Plugin for Gemini CLI by heygen-com

About the project

HyperFrames is an open-source framework that turns HTML, CSS, media, and timed animations into deterministic MP4 videos. It is used locally, by coding agents, and in hosted authoring workflows to create rendered videos from web-based designs. Its catalogue add-ons provide skills, agents, instructions, hooks, settings, and a plugin for agent-driven video production.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Security

Grade A, and why

hyperframes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads gemini-extension.json. This mod also ships 20 executable files (examples/aws-lambda/scripts/_aws-isolation.sh, examples/aws-lambda/scripts/_s3-purge.sh, examples/aws-lambda/scripts/_semantic-compare.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Recreate any web animation from a screen recording. Drop a video of an animation you like, motiscope measures its timing and curates keyframes, and your agent rebuilds it as GSAP, CSS, Framer Motion, or Lottie code. Works in Claude Code, Codex, and Cursor.
