01 / Overview

About

html-video is the Open Design family's motion-focused meta-layer. Given a description, article URL, or GitHub repository, a local agent creates a multi-frame content-graph storyboard and self-contained animated HTML. Hyperframes then records frames with headless Chromium, while ffmpeg encodes and concatenates them into MP4. The official project distinguishes the shipped Hyperframes engine from adapters still on the roadmap.
