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

Kino AI launched on Hacker News as a combined media manager and video editor that stores footage and assets, offers a rich editor, and provides review links for teammates, letting colleagues and coding agents like Codex and Claude Code work on the same timeline. The editor is code-first, built on Remotion, with all editing, motion graphics, timeline dragging, comments, and 3D scenes expressed as code, and it is fully collaborative and real-time with visible teammate cursors. Footage is transcribed, embedded, described, and face-detected, with a low-res proxy uploaded so teammates and cloud inference can access it while local scrubbing uses custom pro media decoders.
