HyperFrames is an open-source project from HeyGen for creating video with HTML, CSS, media assets, and seekable animation code. Instead of treating a binary editor project as the source of truth, it treats the composition as code that can be versioned, reviewed, generated by agents, and rendered repeatedly.
How code becomes video
A HyperFrames composition describes the layout and animation using familiar web technology. During rendering, a controlled browser advances the composition frame by frame, captures the output, and encodes the frames into video. This deterministic approach is useful when the same data-driven template must produce consistent results many times.
Why agents fit this workflow
Coding agents already understand component structure, CSS, animation libraries, and source control. HyperFrames provides skills and tooling that help an agent author a composition, use reusable blocks, preview frames, identify errors, and render the result.
Strong use cases
Product demonstrations and launch graphics
Data-driven charts and recurring reports
Branded social clips generated from templates
Developer tutorials with animated interface diagrams
Batch video rendering in CI pipelines
What it is not
HyperFrames is not primarily a text-to-video diffusion model. It excels at designed motion graphics and deterministic rendering. It also does not remove the need to license fonts, music, stock media, or other assets used in a composition.
Getting started
Follow the quick start in the official HyperFrames repository. Build a five-second composition with simple shapes and one animation before attempting a complete video. Keep the project in version control and render a few reference frames in automated tests to catch unexpected visual changes.
