From my understanding the way you create ai video is through prompting, and when you want to change or tweak a video you adjust the promp wich spits out a completely new video. I may be wrong, if I am please correct me.

although tbh I don't hate the idea of AI ad's as much as i do other stuff. Making your advertisements intentianally garish and inuman is more honest to these companies morals and identity than the genuine filmmaking that they often employ.

-, it just creates the whole thing for you. "Democratizing filmmaking" means nothing because your not making a film! your just typing shit in and then something kind of what you thought comes out! who in their right mind would enjoy that
