Mystical Footage in Video Format Genereated by AI form Scratch?

Hello all,

I wanted to know if anybody knows an AI that can generate mystical footage in video format. I want footage for my YouTube channel, if someone can point me in the right direction that would be very appreciated. I did a search and came up with Kawpwing and Synthesia. The former supposedly be able to create mystical footage from scratch.

According to ChatGPT.
I need to type my topic in a window, but nowhere do I see any window where I can type in. I checked for tutorials but only found a guy using his own recorded video as a basis, to which he can change the avatar. This is not what I’m looking for I want an AI to create mystical footage from scratch without me having the provide any recording. And Synthesia is also not what I’m looking for as it can only make videos with avatars.
