Cardboard - Cursor for video editing

Cardboard is an agentic video editor that gets you from raw footage to final cut in minutes. Think of it like an intelligent collaborator, one that understands what's in your clips, has the taste to know what a good edit looks like, and executes your vision.

the "describe the edit, it executes" framing is sharp. curious how the agent handles first-time users with no editing history - does it lean on the clarifying questions a lot early on? the cold start problem for understanding someone's aesthetic is one of the harder ones. congrats on the launch

 

The agent asks more and more questions if user says "can you make it into a cool vlog?"

We're also planning a feature where users can upload a video/image they like and they'll be able to get closer to that using Cardboard's agent :)

"Cursor for video editing" and backed by YC. My video editor just started updating their resume. Upvoted. 🎬

 Haha!

Max video length it can handle at once?

 

It depends on how much memory your PC has. There should be no limit in theory but we've seen it produces good results for raw footage of upto upto 60 gb/8hr of footage.

Beyond that, we still support it, but the agent quality degrades because of context limits, we're working on smarter context management.

This is awesome, its amazing to see how many functions people perform online are now totally turning out to be prompt and usage based.

 you can just type things into existence :)

Great product, very very useful for launch videos!!

 ty ty dhruv!

Woah this is insane. I remember someone debating on twitter about the idea that building cursor for video editing is impossible to build. Guess that didn't age well haha.

Que: why browser and why not a mac app?

Btw love the name guys. Keep going. Will definitely try.

 Thanks!

It is definitely hard but not impossible. Browser allows it to be more accessible and collaborative in nature.

amazing product i have come across in last couple of days amazing

 thanks sammy, glad you liked it.

This has good potential

 I agree!

I really appreciate the live collaboration feature weaved into this. Is there a comment-and-resolve flow on the timeline or is that on the roadmap?

 

Yep, feels like you read our minds!

This looks very cool. Congrats to you both on the launch guys. Is Final Cut export on your roadmap?

 We already export FCPXML :)

 Oh cool! I somehow missed that as I thought it was only Premiere and Resolve as listed on your pricing page.

 Thanks for notifying, we'll update that!
