Nothing personal. I do work in the biz so my bias clearly favours real crews / actors. Once we take the human element away from art I just don't see what the point is. But you're absolutely right in that it will carve out a niche for itself, it already is.
I mean I favour real actors and crews too, obviously. I'm not saying it's all sunshine and roses, there are legitimate issues here that we need to figure out. Like anything else, some elements are good and some are bad. I have no interest in AI making movies or albums of its own accord.
I'm just saying for a video like this, if a person sits down and maps out a parody trailer mashup of Lord of the Rings and Star Wars, coming up with ideas of scenes and shots, then edits it together into a trailer, it's not feasible to make this video with real actors cause it would obviously cost a ridiculous amount of money. So you can animate it (again, also would take a massive amount of time and effort) or have AI generate the images.
And the idea of "copyright issues" is just a red herring because this is not a real movie people will pay to go see. Sure someone will try that at some point but this is not that. It's just a clever 2-minute mashup/parody that is fun to watch (or in your case, not fun to watch, I guess).
I agree it's kind of the wild west out here trying to determine what's acceptable and what's not. I guess you could just assume a "nerd" just prompted ai to make a trailer, but it usually ain't that simple. With something cohesive like this, it likely involved a lot of human work to create it. Just like the "There I Ruined It" guy doesn't just prompt audio recordings, he "creates these remixes by building new instrumental backings in a DAW, recording vocals, and using AI to map specific artists' voices onto tracks".
