HeyGen releases frame.md to teach AI agents branded motion design

HeyGen released frame.md, a motion-specific markdown specification that governs how AI agents generate video. Building on the HyperFrames framework, the spec defines video-native elements like pacing, scale, and dwell time. It serves as a bridge between static brand rules and deterministic (predictable and repeatable) video output.
Format
Markdown .md
Core Parameters
Pacing, scale, dwell, and motion
Input Support
design.md translation
Framework
HyperFrames
Availability
Open source via GitHub

While the DESIGN.md standard helped agents follow brand rules, they often defaulted to static layouts like webpages. By adding a motion layer, HeyGen ensures agents understand how a brand moves, not just how it looks. This benefits systems like Hermes Agent that manage autonomous video production.

Users can upload a design.md file to the HyperFrames platform to generate a corresponding frame.md spec. This file directs compositions within the open-source HyperFrames framework. The specification is available via a web interface and GitHub for immediate use in agentic workflows.

Introducing frame.md, a spec built for videos & motion design.md kept your brand consistent across screens but when applied to videos, agents translated it back into webpages and decks frame.md teaches your agents how to make branded video turn your design.md into frame.md ↓ https://t.co/TZpTUBajhq

Still wondering? A few quick answers below.

It is an open-source markdown specification created by HeyGen to define motion design rules for AI agents. It provides structured instructions on how a brand should move within a video frame, covering elements like timing, scaling, and pacing.

While design.md defines static brand elements like colors and fonts, frame.md translates those rules into motion. Users can upload a design.md file to HeyGen's platform to automatically generate a frame.md file that agents use to create branded video content.

Without specific motion instructions, AI agents often default to translating brand guidelines into static formats like webpages or slide decks. frame.md provides the necessary motion instructions to ensure agents produce professional-grade video that remains consistent with a brand's identity.
