# HeyGen open-sources its HTML-to-MP4 tool

By Steven Van · 2026-04-17

HyperFrames installs as a coding-agent skill, letting tools like Claude Code render video straight from HTML.

HeyGen open-sourced **HyperFrames**, the tool it used internally to build its own launch video, which converts HTML into MP4. It's built for agent use: install it as a skill with npx skills add heygen-com/hyperframes, and coding agents like Claude Code can generate video directly from HTML rather than through a traditional editor. This sits apart from [HeyGen](<https://creatorstoolbox.com/tools/heygen>)'s avatar and translation features, more a developer tool than a talking-head one, and the announcement itself was posted as an [X post](<https://x.com/i/status/2044827454460871072>).
