How to create an AI Video more than 4 or 10 seconds please?

Dearest Bro, I sincerely thank you for your reply which is very informative. I will try to give a try by tomorrow and i will update you. Do I need to be a Pro user here? What advice can you give me please? I have another request regarding using LoRa, or contents above 18? Is this something we can discuss here? Thanks
