[AI Tools 精品 AI 工具导航] htmlvideo.ai — A Collection of Remotion Apps, Templates & Video Use Cases

v2ex · 2026-06-08 05:34:59+08:00 · tech

I’ve built htmlvideo.ai , a curated hub for Remotion-based apps, templates and real-world video use cases. As the foundational technology for programmable video rendering in the community, Remotion powers nearly all high-performance browser-side video rendering today. With the rapid advancement of AI Coding Agents, we can expect an explosion of code-generated videos with increasingly polished quality. I created this site to help myself and fellow developers learn and adopt Remotion more efficiently. My hope is that htmlvideo.ai will serve as a starting point for the great journey of HTML as Video in the AI era. I will keep updating this site continuously, until everyone can easily leverage AI agents including Claude, Codex, OpenClaw and Hermes to create and edit custom videos effortlessly.

感觉我做的AgentHTML有点太简陋？
