HyperFrames: HTML to MP4 for Agents

The engine almost every agent video skill renders with. Open-sourced by HeyGen. The agent writes an HTML page with GSAP animation, HyperFrames renders it to MP4. No timeline editor, no clicking.

I use it for my own explainer videos. The new storyboard step shows you still frames first, so you fix the direction before you pay for a full render.
