Cardboard: agentic video editor that takes raw footage to a cut

What it is. Cardboard is an agentic video editor that takes raw footage and works toward a finished cut on its own. You feed it clips, tell it what you are going for, and it makes structural editing decisions rather than waiting for you to make every one yourself. The pitch is something like Cursor for video: a collaborator that understands what is in the material and has enough taste to know what a decent edit looks like.

Why it matters. The part of editing that burns the most time for most people is not the fine cut, it is the rough assembly. Watching everything, deciding what to keep, building a first structure. Cardboard takes a swing at that stage, which means you could come in at the point where the work actually requires your judgment instead of just your patience.

How to use it. Bring in your raw clips and give Cardboard a clear sense of what the piece needs to do: a 90-second brand film, a talking-head cut with the best takes, a highlight reel from an event. Let it build an assembly. From there you treat it the way you would treat a rough cut from an assistant editor: watch it critically, pull out what is working, redirect what is not, and take it the rest of the way yourself. The collaborator framing is the right one. You are not handing the edit off, you are skipping the part that did not need you anyway.

Limits. How much you can trust the assembly depends entirely on how well it reads your material and your intent, and that is genuinely hard to know without running your own footage through it. Agentic tools at this stage tend to do well on structured content and struggle with anything that needs a strong editorial point of view or a feel for pacing that goes beyond the obvious. Pricing and availability details are worth checking directly, since the product is still early.
