Short answer
A free HyperFrames guide as of November 2026: what HyperFrames is, how HTML becomes video, the free Studio desktop app, adding HyperFrames skills to Claude Code, Codex, or Cursor, the connector for Claude and ChatGPT with cloud rendering, your first video step by step, editing by typing, pointing, or drawing, ready-made blocks, local vs cloud rendering, HyperFrames vs Remotion, good uses, and tips.
HyperFrames is a free, open-source framework from HeyGen that turns HTML, CSS, media, and animations into MP4 videos. It is built for AI agents: you describe a video, and an agent writes and renders it. It uses the Apache-2.0 licence.
If an AI can build a web page, it can now build a video.
02
How it works
Each video is a web page with a timeline
Animations are seekable, so every frame renders the same way every time
A headless browser captures frames and FFmpeg turns them into video
03
Three ways to use it
Studio app
A free desktop app for macOS, Windows, and Linux where you describe a video and an agent builds it
Agent skills
Run npx skills add heygen-com/hyperframes to teach Claude Code, Codex, or Cursor how to build HyperFrames videos
Chat connector
A beta connector for Claude, ChatGPT, and Grok that renders in the cloud under your HeyGen account
04
Your first video
Install the Studio app, or add the skills to your coding agent
Describe the video: length, format, style, and message
Watch the live preview
Ask for changes
Render to MP4
Make a 20-second vertical ad for a coffee subscription: dark background, big bold captions, three product benefits, a price reveal, and an end card with the website.
05
Edit naturally
Type changes in plain language
Point at parts of the picture
Draw or comment on frames
06
Use ready-made blocks
HyperFrames has a registry of hundreds of ready-made blocks and components, such as transitions, titles, captions, charts, and overlays, that agents can install and edit.
07
Local or cloud rendering
Local
Free, runs on your computer, but heavy renders can make laptops hot and slow
Cloud
Renders on HeyGen’s servers through the connector or cloud option
While iterating, check single frames or short low-resolution drafts, and do one full-quality render at the end.
08
HyperFrames vs Remotion
HyperFrames
Plain HTML and CSS, made for AI agents, Apache-2.0
Remotion
React-based video framework with its own licence terms
Both render video from code. Pick the one that fits your agent and your team’s skills.
09
Great uses
Product launch and promo videos
Social clips with animated captions
Explainers with charts and diagrams
Title cards, lower thirds, and overlays
10
Tips
Give the agent your brand colours and fonts first
Plan scenes before animating
Keep captions inside platform safe zones
Use only music, fonts, and footage you have rights to
The golden rule
Do not render over and over. Describe the video clearly, check frames and drafts as you go, and do one final render when it is right.
