Show HN: Kimu – Open-Source Video Editor (trykimu.com)

>A cute AI agent (coming soon!)

Why??? You don't need this just because "AI" is popular right now, it will distract you from the goal of developing "video editor built for the web". It's really not going to improve the video editing experience.

Another remotion video editor with vibe-coded features? There are so many of them... A video editor in the long term needs to be mobile-first. A web video editor in the big year of 2025 is not going to move the needle. Capcut has a free desktop app that you must compete with. I think a better idea is building a mobile video editor, it's much harder to vibe code. To be the "Cursor for Video Editing," it's a must.

So I appreciate the aim here, but for me to trust any video editor, I need to see an example timeline that’s like, 30 minutes long with clips from at least 10 1080p video files and at least one effect on each track.

And for the record I wouldn’t consider that a stress test (a stress test would be more like 3 hours, 100 tracks, 4K and like a dozen precomps that are being reversed or something). That’s just to make sure this thing won’t fall over during casual usage.

You may be inclined to respond that your editor is targeting beginner editors, to which I’d note that beginner editors are MUCH less disciplined than experts when it comes to trimming footage, splitting things up into comps, pre-rendering chunks, using proxies, etc. Beginner editors (I’d know, I used to be one) will dump a 1 hour 4K-HDR iPhone video of a presenter speaking, and a screen recording of presentation slides they accidentally took in 4K60 into your timeline. Being able to demonstrate that you’ve got that level of memory management handled is what separates video editors people can use from mere “good ideas”.

Edit: Another thought, you call your product “Cursor for video editing”, and that’s a valid goal. But bear in mind that a LARGE part of why Cursor is successful is because they didn’t try to build an IDE from scratch. They got to absorb all of the nice UX (not to mention the extensive plugin ecosystem) of VS Code, and then spend their time on AI features. If that’s how you want to spend your time, you definitely don’t want to be building an editor from scratch.

Well, my very simple 3-minutes playing around with this were enjoyable.

Please add the ability to center images if you upload different-sized images, so the smaller images don't all clump in the upper left corner.

I'll try this with larger video clips later

You should prepopulate the timeline with an in progress edit so people can jump in start playing with it.

How does it compare with OpenCut?

I would like someone to make either a voice controlled or gesture based video editor. I have not seen a single one for obvious reasons. Voice controlled would go like "OK search for the input.mp4 file " and drag it at 2 seconds "Now, play at 5x speed from 1 minute" "After a few seconds, you say stop and it stops at that frame" "Cut it here" "Now go 4 mins ahead" "Stop, cut it here" Imagine a video editor where you dont even need the mouse and keyboard

Looking good, but I think you should be able to drop image/video files into the editor.

Can it be installed in an existing project as, say, a react component? Or is it standalone only?
