You’d need your private data center, a video model, and skills with video models. I think all publicly available models don’t do more than minutes at a time and will probably not accept fucking with copyrighted material. But if you ran your own operation you could probably do it in a month or so. You shouldn’t though for a laugh because you’ll be personally responsible for killing a polar bear family.

OP is lost. This is “no stupid questions”

You can’t achieve that with AI, but you could learn video editing skills and it wouldn’t be too hard to super impose Xmas hats.
