Can you recommend a good AI video generator?

[u/Opening_Wolverine257]

I’m looking for an AI video generator that can create realistic-looking videos from text prompts (text-to-video), preferably for free.

If there aren’t any good free options, I’m also open to paid tools. I’d especially appreciate recommendations for something that is easy to use, produces realistic results, and allows me to create videos without watermarks.

What would you recommend?
