How to choose an AI video ad generator: a 9-point checklist
There are now dozens of tools that promise a finished video ad from a prompt, a link or a template. They are not interchangeable. This checklist helps you compare them on what actually decides whether the ad is usable.
What are the main types of AI video ad tools?
Most tools fall into four families, and knowing which one you are looking at explains most of the differences in output.
- Text-to-video models generate every frame from a prompt. They can be striking but they invent the scene: your product, your logo and your interface are re-drawn, so they drift from reality.
- Avatar presenters put a synthetic speaker on screen reading a script. Useful for explainers, less so for product or brand visuals.
- Template editors give you a timeline and styled layouts. You do the creative work; the AI mostly helps with captions and trimming.
- Link-to-ad generators read a web page, then assemble an ad from the real assets they find there. ClipMotion works this way: you paste a product page or website address and it builds the script, voice-over, captions, music and edit.
1. What does the tool need as input?
A blank prompt asks you to be a creative director. A link asks almost nothing: your page already contains the product, the photos, the logo, the colours and the claims. If the tool cannot read a page that blocks automated access, check that you can add photos by hand instead.
2. Does it keep your real product intact?
For e-commerce this is the most important test. Generative video tends to reinvent the product, so the shoe has the wrong sole and the logo is a blur. Look for tools that use your actual photos and only change the background. ClipMotion removes the plain background and places the original product on a new setting, so its shape, logo and colours stay as photographed.
3. How well does it respect your brand?
Check that it finds your real logo, derives the palette from it, and uses the same typeface and caption style from the first frame to the last. A video that could belong to any company is an ad for the category, not for you.
4. Where do the footage and music come from?
Ask for the licence. Royalty-free stock libraries and music composed by the tool avoid rights claims; scraped clips and unlicensed tracks do not. Also check relevance: footage chosen from abstract words (growth, innovation) looks generic, while footage chosen from what a camera can film in your customer's day looks specific.
5. Is the voice-over natural, and are captions built in?
Most viewers watch with the sound off, so captions are not optional. Look for word-by-word captions in short groups, voice-over in your language, and spoken numbers and prices that are read correctly.
6. Which formats can you export?
You need vertical 9:16 for Reels, TikTok and Shorts, square 1:1 for feeds, and horizontal 16:9 for YouTube and websites. The tool should reframe the composition for each, not just crop it. See our guide to formats and lengths.
7. How much can you edit afterwards?
A first draft is never perfect. You should be able to rewrite a line, swap a clip or change the music and regenerate without starting over.
8. Who owns the output, and is there a watermark?
Read the terms on commercial use and on watermarks. A free preview with a watermark is fair; a surprise paywall at export is not. ClipMotion lets you try it without an account, exports a watermarked preview for free, and sells the clean export per video or through a subscription.
9. What does the price really include?
Compare the cost per finished video, not the headline plan. Count credits, resolution limits, export fees and whether footage and music are included.

Frequently asked questions
What is an AI video ad generator?
It is a tool that produces a short video ad automatically: script, visuals, voice-over, captions and music. Some generate frames from a prompt, others assemble the ad from your real photos, website and brand.
Which kind of AI video ad generator is best for e-commerce?
One that uses your real product photos and only changes the background, so the product is never reinvented. That keeps shapes, logos and colours accurate.
Do I need a video editor or a filming crew?
No. A link-to-ad generator needs only a product page or website address. You can still edit lines, clips and music afterwards.
Is the footage safe to use commercially?
Check the tool states its licences. ClipMotion uses a licensed royalty-free stock library and music composed by ClipMotion, so there are no rights to clear.
