I have found an text to video ai wich is even better than Luma Ai, its called Vidu, the thing is, this ai may sometimes give shitty results but of all the Ai's i ever saw, this one is the only one who tries to make inflation content, normally i have to make "magic" or 1 or even use 2 images like in luma, but this Ai can make it with a single prompt, but i rather recommend still use a image btw, and the inflation that makes looks jiggly, maybe is bc i added "Water balloon", so i recomend your prompts to be like this "action movie.
