Give your brand videos a motion language

A DESIGN.md describes how a brand looks. It says nothing about how it moves, and motion is where brand videos live or die. HeyGen's HyperFrames closes that gap with FRAME.md: your design system extended with a motion language, the easing curves, transition style, and pacing that fit the brand's character. A sharp, technical brand moves differently than a warm, editorial one. The workflow starts with the file Dembrandt already produces. Run the CLI with --design-md to render the live site headlessly and emit a DESIGN.md from computed styles: verbatim hex values and the fonts that actually load, never colors estimated from a screenshot. HeyGen's own quickstart recommends this as the deterministic path. Let an agent add a voice section derived from real site copy, upload the file at hyperframes.dev/design, and download the generated FRAME.md into your project folder. From then on it rides along with every video the agent composes: website-to-video, launch videos, PR-to-video, all in your brand, moving like your brand.
