Launch HN: Kino AI (YC S23) – AI media manager and video editor

By · Published by Everything Blog

In short

The platform relies on a code-first architecture where timeline adjustments, comments, and 3D scenes are expressed as code. Everything within the system—including individual projects, clips, frames, lines of code, and comments—is assigned a specific URL to serve as a shared source of truth for both humans and AI agents. The software features real-time collaboration, showing live user cursors and current timeline positions while swarms of agents concurrently perform tasks like rotoscoping or color adjustments. To support heavy workloads, the system generates low-resolution proxies for cloud inference while custom decoders handle professional formats locally via WebCodecs.

Hi HN! I'm Luke from Kino (

https://kino.ai). Kino lets you make great videos with your agents and your teammates. Storage of footage and assets, a rich video editor, and review links for teammates are all bundled into one. Your colleagues and Codex / Claude Code can work on the same timeline with review notes and footage all in one place. See a basic overview at

https://kino.ai/launch-videoOpus 5.5 can edit videos and make great motion graphics now. But with a raw agent harness, you need to describe tiny edits either in words or in quick one-off UIs, you can’t refer to footage shared across your devices, and feedback from teammates comes as screenshots on Slack.

Kino is code-first. All editing, all motion graphics, all dragging of timeline items around, all teammate comments, and all 3D scenes are expressed as code, built on Remotion. This was hard to get right, as we found ourselves building a what-you-see-is-what-you-get editor for React, which we then turned into a video editor. For our launch…
