Heygen HyperFrames

Heygen HyperFrames is an open-source framework designed for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. It is built for agents and allows users to define a video as HTML, adding data attributes for timing and tracks. The tool uses GSAP, CSS, Lottie, Three.js, Anime.js, WAAPI, or a custom frame adapter for seekable animation. HyperFrames is used in production at HeyGen and has community examples from teams like tldraw and TanStack.

The framework works by allowing users to write HTML and render video, with features like adapter-based animation, HTML-native compositions, and deterministic output. It supports various tools and integrations, including Claude Code, Cursor, Gemini CLI, and Codex. HyperFrames also has a growing set of tools around HTML-native video creation, including a catalog of pre-built components and a showcase of finished videos.

The tool is most valuable for teams and individuals who need to automate video creation, such as marketing teams, video producers, and developers. It is particularly useful for those who want to create videos with complex animations and effects, but do not have extensive video editing experience. With HyperFrames, users can create high-quality videos quickly and efficiently, without requiring significant manual editing or post-production work.
