HyperFrames adds a free 85k-asset media library
By Steven Van ·
Agent video framework HyperFrames now sources music, images, SFX and logos in-workflow, free with a HeyGen login.
HeyGen filled in the biggest gap in agent-made video: the assets. HyperFrames, its open-source framework that turns HTML and CSS into rendered MP4s, now has a built-in media library, 10k+ music tracks, 75k+ images, sound effects, and logos, free with a HeyGen login. When the catalog doesn't have what a project needs, the same layer can reach HeyGen's generative models and make it.
Why assets were the bottleneck
HyperFrames' pitch is "write HTML, render video, built for agents": an agent composes a video the way it writes a web page, and the framework renders it deterministically. Agents got good at the composition part fast. What stalled them was everything around it, hunting for a background track with the right energy, a clean logo, a whoosh for the transition. Those searches used to bounce the agent (or you) out to stock sites. Now they resolve inside the workflow.
How /media-use works
The library is exposed through the media-use skill, which the HyperFrames repo describes as the framework's media operating system. Ask for music, SFX, images, icons, logos, voice narration, or even color grading and LUTs, and it either pulls from the catalog or generates the asset via TTS, music, or image models when nothing fits. It also handles transcription, captioning, and background removal along the way.
The detail that shows real workflow thinking: assets save to your machine, with a manifest and ledger tracking what's been used. Your next project skips the search, reuses what you already pulled, and never regenerates an asset it already has. Across a channel's worth of videos, that consistency, same tracks, same logo files, same look, is what makes output feel produced rather than assembled.
A rapid buildout of the agent video stack
The media library extends a relentless HyperFrames release pace: nine agent-routable workflow skills in June, cloud rendering so your laptop isn't the bottleneck, the open-sourced Keyframes motion system in early July, and now assets. Piece by piece, HeyGen is assembling a complete production pipeline where the agent handles composition, motion, rendering, and now sourcing, and the free-with-login library gives every HeyGen account a reason to route that pipeline through HeyGen's ecosystem.
Try it
Install the skills suite with npx skills add heygen-com/hyperframes, then invoke /media-use when a composition needs music, images, SFX, or a logo. It's free with a HeyGen login, and the assets land as local files ready for your current and future projects.
