WebMotion
Browser-native, deterministic video composition
Compose video in the DOM, encode it with WebCodecs, download an MP4. No FFmpeg, no headless Chrome, no render farm. Every frame is a pure function of the frame index.
Hey everyone! Thanks for checking this out.
Wanted my AI agent to create beautiful videos without opening a video editor.
Every tool I tried could generate something, but none let the agent actually see the result, make changes, watch it again, and keep refining until it looked right.
So I started building a workflow around web native technologies that gave the agent the ability to inspect what it was making, iterate, and keep improving the output instead of treating video generation like a one shot prompt.
Happy to answer any questions and would love to hear what you build with it.
