We built in HeyGen an open source framework specifically made for Agents solving our own pain point that we had when the agents tried to write Remotion. React is not agent-friendly at all, and Remotion is a custom framework where the agent has to first know how it works to make a video. That's changing with HyperFrames, it's just a superset of HTML, and agents know how to write HTML + GSAP by default in their training data, so it's more difficult to make failures with it! One cool thing is that in HyperFrames every web library can be used inside HyperFrames by default, we support all the Web, compared to Remotion where they need to make an adapter for it, and the agent would have to learn another primitive...
