You have probably seen one without knowing what it was: a drinks can the size of a building on a real street corner, a sneaker unfolding out of a subway floor, a car driving out of a billboard. Those are CGI ads. Here is what they are, what they cost, and whether they are worth it for a smaller brand.
What a CGI ad is
CGI stands for computer-generated imagery. A CGI ad places a digital version of your product into a real filmed location, at a size or in a way that could not happen in real life. The background is real. The product is built in 3D and lit to match.
The effect only works because the viewer half-believes it. That pause, the second where someone asks “is that real”, is the whole point.
How it is different from a normal product video
- A normal product video shows your product being used. A CGI ad shows it doing something impossible.
- A normal shoot needs the product in hand, a location, and a crew. A CGI ad needs a 3D model and a plate shot.
- A normal video explains. A CGI ad gets attention. They do different jobs.
Why brands use them
- Stopping power. In a feed full of talking heads, a 40-foot handbag stops the thumb.
- Shareability. People send them to each other, which is free distribution.
- No logistics. You can place your product in Times Square without a permit, a shoot day, or a flight.
- Launches. They work hardest on a new product, a new flavour, or an entry into a new market.
What they are bad at
CGI ads get views. They do not explain a product, build trust, or close a sale on their own. Nobody buys software because of a CGI ad. They are the top of the funnel, and they need something behind them.
If what you actually need is a believable person holding your product and saying why it is good, that is AI UGC ads, not CGI.
What goes into making one
- The idea. One impossible moment, in one sentence. If it takes a paragraph to explain, it will not work.
- The plate. A real video or photo of the location, filmed or licensed, with the camera movement locked.
- The 3D model. Your product rebuilt accurately, including the label, the material, and how it reflects light.
- Tracking and lighting. Matching the real camera move and the real light so the product sits in the scene instead of floating on it.
- Render and finish. Shadows, reflections, grain, sound.
What CGI ads cost
Traditional CGI production runs from a few thousand dollars for a simple single-shot piece to well over twenty thousand for a hero film with complex animation. That is why the format was mostly limited to large brands.
AI-assisted production has changed the lower end of that range considerably. A short, single-moment CGI piece is now within reach of a mid-size brand rather than only a national one. Our CGI ads service covers that end.
Which businesses they suit
Strong fit: consumer products with a recognisable shape or package, drinks, cosmetics, footwear, cars, consumer electronics, and anything launching.
Weak fit: services, software, local trades, clinics, and anything where the buyer needs reassurance rather than spectacle. Those get better results from video with a real person in it.
How to judge a good one
- Does the shadow fall the right way? Wrong shadows are the giveaway.
- Is the product recognisably yours in the first second, at thumbnail size, with sound off?
- Is there one idea, or three competing ones?
- Would you watch it twice?
How to use one once you have it
Do not just post it and hope. Run it as a paid ad to build an audience of people who watched it, then retarget those people with something that actually sells: a product video, an offer, a review. The CGI piece gets the attention; the second ad does the work.
Worth it or not?
Worth it if you have a physical product with a strong shape, a launch coming, and something to retarget people with afterwards. Not worth it if you have no product to show, or if you are hoping a single video will fix a demand problem.
