So I've been playing around with this A.I. website,
https://hailuoai.video/, the last few weeks that can take a prompt you use and turn it into a short 6 second video clip. The results can vary wildly even when using the same prompt over and over, but now and then the clip it comes up with is actually pretty good. It's definitely a step up from anything else I've tried. It isn't free anymore, but it has potential. I'll share a clip I made so you can see what it can come up with.
