How to make a video ad with AI: the step-by-step method
AI now makes it possible to produce a short video advert with no filming or studio. The result depends mainly on the message and the script, not the tool. Here is the method, and the rules to follow in 2026.

The answer in 30 seconds
In short
To make a video ad with AI, start with a short script: a hook in the first few seconds, a problem, your solution and an action to take. Then generate the images or video shots, add a voice and subtitles, and edit it all together. Since 2 August 2026, under the EU AI Act, a realistic video that could pass for real must be disclosed as AI-generated.
Generated visuals
Shots, products, settings or an avatar.
A voice and subtitles
Many people watch with the sound off.
A clear label
When the content could seem real.
Your video ad in 6 steps
A 15 to 30 second video is often enough. The shorter it is, the more every second counts.
What you must respect in 2026
An AI-generated advert is still an advert. All the usual rules apply, plus a few new ones.
Disclose realistic content
The EU AI Act requires you to disclose an image, sound or video generated or altered by AI that could seem authentic.
Image and voice rights
Never reproduce a real person's face or voice without their written consent.
Rights to the elements
Check the commercial use terms of every tool, piece of music and image you use.
No misleading advertising
The product shown must match the product sold. An invented or exaggerated result can be a misleading commercial practice.
Which format for which use
The same script can be adapted into several formats. Think first about where the video will be watched.
| Use | Recommended length | Format |
|---|---|---|
| Ad on mobile | 15 to 30 seconds | Vertical |
| Sales page | 60 to 90 seconds | Landscape or square |
| Product presentation | 20 to 45 seconds | Square or vertical |
| WhatsApp message to your customers | Under 30 seconds | Vertical, lightweight |
These lengths are common guidelines, not rules. Test and keep what works for your audience.

Your questions, our answers
How do you create a video advert with AI?
Write a short script, break it into shots, generate the images or video for each shot, add a voice, music and subtitles, then edit it all together.
Do I have to say an advert was made with AI?
Since 2 August 2026, under the EU AI Act, AI-generated or altered content that could seem real must be clearly disclosed. Obviously fictional content is treated more flexibly.
Can I use an AI-generated celebrity voice or face?
No, not without the person's written consent. Using someone's face or voice without permission can breach image, personality and data protection rules, whether they are famous or not.
How long does it take to make a video ad with AI?
A simple video can be made in a few hours with a script ready. The longest part is often writing the message.
How long should a video advert be?
Often 15 to 30 seconds for an ad viewed on a phone. The key point must come across in the first few seconds.
Do I own videos generated by AI?
It depends on the terms of the tool you used and on your own creative input. Read the commercial use terms and get advice if in doubt.
