HeyGen open-sources its HTML-to-MP4 tool

By Steven Van ·

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's avatar and translation features, more a developer tool than a talking-head one, and the announcement itself was posted as an X post.

Talking-head videos from AI avatars — pick from hundreds or build your own from a clip, script in 40+ languages, and translate with lip sync intact.
