AI character generator: one invented person, the same in every shot
By VODOO AI · · 4 min read
Making one good-looking AI person is easy. Making the same person twice is the hard part: change the pose, the light or the outfit, and the face drifts into someone else. For a brand that wants a recurring face across a campaign, a series or a feed, that drift is the whole problem.
This guide covers how VODOO keeps one invented character consistent: describing them once, building a reference set of angles and expressions, and driving every new picture and video from that set.
Describe them once, in detail
Start with a short description you'll never change. The more specific it is, the less room the AI has to drift.
- Age and build: "a woman in her early thirties, tall and slim".
- Face: shape, eyes, nose, one distinctive detail such as a small scar or freckles.
- Hair: colour, length, texture and how it's worn.
- How they come across on camera: warm, serious, playful.
Build a reference set
One good picture isn't enough to hold a face. VODOO makes the look once as stills, then a reference set from it: front, three-quarter and profile, and a few expressions. Every new picture and video of the character is made from that set, which is what keeps them recognisable in the fortieth shot, not just the first.
Front, three-quarter, profile
- Why
- So any camera angle has something to match
Neutral, smiling, speaking
- Why
- So expressions don't change the face
Full length
- Why
- So build and posture stay the same
| In the set | Why |
|---|---|
| Front, three-quarter, profile | So any camera angle has something to match |
| Neutral, smiling, speaking | So expressions don't change the face |
| Full length | So build and posture stay the same |
Briefs to copy
A woman in her early thirties, tall and slim, warm brown skin, high cheekbones, short natural curls, a tiny gold stud in one nostril, a calm, confident smile. Make her reference set: front, three-quarter and profile, neutral and smiling, plain light grey background.Make this in VODOO →
Our character from the reference set, wearing a rust linen shirt, sitting at a café window in morning light, laughing at something off camera, holding a small paper cup. Candid, 35mm, shallow depth of field.Make this in VODOO →
A man in his forties, broad-shouldered, short salt-and-pepper beard, rectangular glasses, deep-set grey eyes, a slightly crooked nose, friendly and direct on camera. Make his reference set: front, three-quarter and profile, neutral and speaking.Make this in VODOO →
Where a recurring character helps
A face people recognise builds trust over time, the way a familiar shop assistant does. Brands use one character as the presenter of a weekly series, the model in every season's lookbook, or the guide in their help videos.
Keeping them the same in video
Video is where faces drift most, because every frame is a new chance to change. Driving the video from the reference set, rather than from a description alone, is what keeps the identity steady through movement. Short clips hold better than long ones; join several five-second shots rather than asking for one long take.
Invented, and labelled
Characters must be people who don't exist. Don't base one on a real person, a celebrity or someone you know: VODOO holds anything that looks like a known public figure for a person to check before it's made. When an invented person appears in an ad, say it's made with AI. Platforms and, increasingly, the law expect it.

Questions people ask
- How do I keep an AI character consistent?
- Describe the face and body once in detail, make a reference set of angles and expressions, and make every new picture and video from that set.
- Can I use an AI character in ads?
- Yes, as long as they're invented, not based on a real person, and you say the person is made with AI.
- Can the character change clothes?
- Yes. Keep clothes and setting out of the core description, and change them in each brief while the face and body stay the same.
