I don't have anything against stitching together clips to tell your story, but I'm unconvinced that these demonstrate anything like that. As I said in another comment, it seems like you'd need to write a screenplay PLUS all the information the director, cinematographer, etc. use to create an actual movie -- everything from direction for how actors portray scenes to decisions on exactly how shots are constructed, to blocking for multiple actors in a scene, to color schemes...

There are a LOT of choices in making a movie, and if you just let the AI make them, you are getting "random" (uncontrolled) choices. I don't think that is going to compare favorably to the real thing.

If you can specify all that, then it's just a tool. Cool. But it's still going to take pro-level skills to use it.
