This is the overview article. It covers what these tools do, what they do not, and how to get a useful answer about your own catalogue without spending much.
What the category actually is
An AI video generator for e-commerce takes a product and returns an advertisement. The good ones do three things in order: read the product, plan the ad, then render it. The step that separates results is the middle one, because a tool that renders straight from your photographs produces a montage, and a montage is not an advertisement.
The inputs
A product URL is the richest input. Shopify, Amazon, AliExpress, eBay, Etsy, Temu and thousands of other stores are read directly, giving the planner your title, description and images.
Photographs work nearly as well and are the fallback when a site blocks automated reading. Product alone, plain background, in focus. Avoid images containing people, which automated content checks on video models often decline.
A description works for concept testing, when nothing is live yet.
The output, concretely
A standard MP4 in 9:16, 16:9 or 1:1, at 720p by default and 1080p on the premium models. Short single clips of about 12 seconds, or multi-chapter videos of 24, 32 or 36 seconds assembled from 12-second chapters with audio continuity across the joins.
You own the commercial rights. The file works on product pages, in organic posts and in paid campaigns, with no player to embed and no ongoing dependency.
Where to place it, in order of return
Paid social first. Feedback arrives in days, and creative fatigue means fresh assets have continuous value. If you place a video in one location only, place it here.
The product page second, near the images. This is where video answers the hesitations photographs leave: scale, texture, mechanism.
Email third, as a still frame with a play button linking to a page where it plays. Most inboxes will not play video reliably, so the click is what you are optimising.
How to know whether it worked
Pick one product with real traffic. Record conversion rate for a full cycle. Add the video and change nothing else. Measure the same window again. Compare conversion rate, not revenue, because revenue moves with traffic.
That is the only number that means anything for your store, and unlike any published industry average, you can defend it.
What it costs
Credit-based. Credits do not expire and each generation shows its exact cost before you confirm, because the model, duration and resolution you choose change the price substantially. There is no unlimited plan.
The entry point is a €5 offer producing one short video from your own product, which exists so the cost of finding out is five euros rather than a production budget.
The limits, stated plainly
It is not a screen recorder. It does not film physical samples, so it cannot vouch for material quality. There is no template library, which is deliberate. And it will not create demand for a product nobody wants: it removes the friction of not being able to see something properly, and where that is not the friction stopping your buyers, better video changes nothing.
