Kino AI turns the edit timeline into code, letting agents and teammates cut the same timeline at once
Synopsis
Kino AI launched a rebuilt video editor on Hacker News that expresses editing, motion graphics, timeline dragging, teammate comments and 3D scenes as code built on Remotion, so agents such as Codex and Claude Code can work on the same timeline as human teammates. Previously, a raw agent harness could only describe tiny edits in words or one-off interfaces, could not refer to footage shared across devices, and received teammate feedback as Slack screenshots. In the launch video, more than five agents edited the timeline concurrently, one rotoscoping and one color grading all media through LUT support.
Interpretation
Kino AI's rebuilt editor lets agents and human teammates collaborate on one video timeline, with editing, motion graphics, timeline dragging, teammate comments and 3D scenes all expressed as code. Previously, a raw agent harness could describe small edits only in words or quick one-off interfaces, could not refer to footage shared across devices, and got teammate feedback as Slack screenshots. The launch video was made entirely with Kino, and during its production more than five agents edited the timeline concurrently while a teammate's swarm worked a few minutes further down.
The editor is code-first and built on Remotion, after the team built a what-you-see-is-what-you-get editor for React and then turned it into a video editor. Code-based editing requires agents to point at specific objects, so projects, clips, footage, comments and replies, a single frame and even the line of code that draws it each have a URL. For the launch video, the author told Claude-with-Kino to find a macOS Leopard install disk and reskin the whole video to match.
To make code-first editing work with real footage, everything is transcribed, embedded, described and face-detected, with local scrubbing after import and a low-res proxy uploaded for teammates and cloud inference. Local scrubbing plus custom professional media decoders let a 250GB ProRes clip from a new iPhone be dragged straight into a Kino timeline. The team built custom decoders for professional codecs such as ProRes, BRAW and R3D, and credits WebCodecs and libraries like Mediabunny as necessary for the performance.
Perspective
What is shown is the making of Kino's own launch video, plus teams managing a company's media in Kino, spinning up agents to make new videos daily and using review links to flag issues.
The launcher says Opus 5.5 can now edit videos and make motion graphics, yet a raw agent harness still struggles to refer to footage and collect feedback; these are the launcher's statements, with no independent comparison given.
