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.

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