How to make a product Demo Video with ai?

I build a website that helps and makes the openclaw install way easier. I dont have the money to pay someone 2 grand to get a 30 second apple like demo to post on the socials. I just need a software to easily make clean product demo videos preferably with the use of AI. I tried Remotion with claude code and not gonna lie it was pretty bad.

Do anyone have recommendations for me?
