You probably won't be impressed and these are legendary figures in experimental film making either.
There is no audience or market for what these tools would be good for.
These videos in the examples are laughable uncreative trash to me but so are big budget super hero human slop.
The main constraint with AI art is that I think the models have been overfit to a very narrow range of visual expression. Midjourney in 2023 could produce the absolute most fucked up images I have ever seen and I have seen a lot of fucked up visual art. That has all been washed out of the model at this point towards a statistical average of what people think is "beautiful".
Also no nudity allowed. What we have is nothing like a model trained to output the sensibility of Hieronymus Bosch or Francis Bacon with nudity. We have literally the opposite of that.
It is the difference between an artist and a "creative". These models are for "creatives", the conformist corporate bullshit version of the artist.
Instead of Hieronymus Bosch we have the statistical average infinite pretty portraits of the virgin mary because we are good people and good corporate citizens.
