AI Video Ads, Step by Step: Make UGC-Style Adverts for Brands (41 Prompts)

Every small business knows that short videos sell better than flyers, but very few can afford actors, a camera crew or a regular content creator. That gap is an opportunity for anyone who can make good AI adverts, whether for their own business or as a paid service.

If you have tried AI video before, you may have seen faces change between scenes, the wrong person speaking, extra jewellery appearing from nowhere or a misspelt logo ruining a good clip. These problems happen because most people start generating before they have a plan. This guide gives you that plan.

Built from a real advert that is live today

I made a 60-second story advert for Souvenir Gifts Haven, a souvenir business in Lagos, with 13 characters and no actors or cameras. It is live on Instagram, Facebook and TikTok. This guide breaks the project down step by step and prints all 41 prompts I used.

What you will be able to do

• Plan an advert so faces, outfits and products stay consistent in every scene

• Create character, location and product reference sheets the AI can follow

• Turn still images into video clips with natural Nigerian-English voices

• Fix the wrong speaker, extra jewellery, misspelt logos and lip-sync problems

• Edit your clips into a finished vertical advert with captions, music and an end card

• Package, price and pitch AI adverts to businesses

What you need

You can make your first advert for free using Google Flow's free daily credits, a free chatbot such as ChatGPT, Claude or Gemini, and a free editing app such as CapCut. For regular client work you will most likely need one paid subscription, and the guide explains the cost honestly.

Who it is for

Beginners who want a practical AI skill businesses will pay for, content creators, social media managers and virtual assistants who want to offer video adverts, and small business owners who want to make their own adverts. This guide teaches a skill that takes practice. It is not a get-rich-quick product.
