VODOOAI ad generator: make video and image ads that look made, not generated
By VODOO AI · · 5 min read
An AI ad generator is only as good as the brief you give it. Ask for "an ad for my serum" and you get something glossy, vague and instantly recognisable as AI. Ask for a person, a moment, a product doing one thing in one light, and you get an ad that stops a thumb.
This guide is the brief that works: what to put in it, how to open in the first second, which shape each platform wants, and a set of ads you can copy and change to your product today.
The five things every ad brief needs
- Who is on screen, described like a casting note: age, style, mood, what they're doing.
- Where it happens, with the light: a kitchen at 8am, a gym at dusk, a studio with one soft window.
- What the product does in the shot: poured, applied, worn, opened, used.
- The first second: the thing that happens before anyone decides to scroll.
- The shape: vertical for Reels, TikTok and Shorts; square or 4:5 for the feed; wide for YouTube.
Open on the hook, not the logo
People decide in the first second whether to keep watching. The best AI ads open mid-action: the cap already twisting off, the coat already swinging, the coffee already pouring. Save the logo for the last two seconds.
Vertical 9:16 ad, opens mid-motion: a woman in her thirties with freckles and natural skin texture presses a dropper of amber serum onto her cheek in a bright bathroom at 8am, soft window light, slight handheld movement. Close-up on the drop meeting skin, then she smiles at the mirror. The bottle stays sharp with its label readable: 'LUMEN SERUM'. Last two seconds: the bottle on a white sink edge.Make this in VODOO →
Vertical 9:16 ad: a man in a rust corduroy overshirt walks out of a café door into low autumn sun, the shirt swinging open in a gust of wind, leaves crossing the frame. Real fabric texture, natural skin, 35mm look, slight film grain. Ends on a still of the overshirt hanging on a chair in the same light.Make this in VODOO →

In VODOO you write the idea once in Create and ask for the shapes you need; each one is framed for its platform rather than cropped from another. For a set of ads tested against each other, the Ads room makes variations from one brief.
Image ads that don't look like stock
Still ads still carry most of the feed. The same rules apply: a real setting, real light, one clear product moment. Avoid the tell-tale AI look of perfect symmetry, glowing skin and empty backgrounds.
Square ad photo: a ceramic mug of flat white on a wooden windowsill with rain on the glass behind, a half-read paperback beside it, morning light from the left. The bag of beans in the corner shows its label 'NORTHFIELD ROAST' clearly. Natural colour, slight grain, shot on a 50mm lens.Make this in VODOO →
4:5 ad photo: a close-up of a hand with a thin gold signet ring resting on a linen sleeve, the other hand holding a cup, visible knuckle creases and fine hairs, warm late-afternoon light. The ring's engraving 'AM' is crisp. Background softly out of focus: a café table.Make this in VODOO →
Which engine for which ad
Different engines are good at different ads. Veo handles people talking and natural sound; Kling is strong on bodies moving and fabric; Seedance is quick for short social cuts; for still ads, Nano Banana keeps a product right across edits and Seedream does polished campaign looks. VODOO picks the right one for each shot when you leave it to the studio, and you can always choose.
You can make your first ads with 300 free credits a month, no card needed. For the whole list of engines compared, see the best AI video generator.
Labels and honesty
Platforms and some laws now ask for AI-made ads to be labelled, especially when a realistic person appears who isn't real. Label them; it costs nothing and audiences mind far less than they mind finding out later. Every file made in VODOO carries the industry-standard marker that says it was made with AI.
Questions people ask
- What is the best AI ad generator?
- The best one is the one that lets you choose the right engine for each ad: some are better at people talking, some at fabric and motion, some at still product shots. A studio that picks per shot beats any single engine.
- Can AI make video ads for TikTok and Instagram?
- Yes. Ask for vertical 9:16, open mid-action in the first second, and keep it between 6 and 15 seconds. Describe a real person and setting so it doesn't look generated.
- Do I have to say an ad was made with AI?
- Increasingly, yes: platforms ask for a label on realistic AI content, and some places now require a clear notice when an ad uses an AI-made person. Labelling is the safe default.
