Hey HN, I built LongCat Video because I was frustrated with AI video generators that only produce 3-5 second clips.

Every tool I tried had the same problem - you'd get a cool 5-second video, then have to generate dozens more and stitch them together. The results were inconsistent and the process was painful.

LongCat Video generates minutes-long videos from text or images with stable motion. No more flickering, no more stitching clips together.

Tech stack: 13.6B dense diffusion transformer model, 720p output at 30fps.

Would love feedback from the HN community. What features would be most useful for your projects?

This is cool excited to test it
