Consistent AI Characters

Consistent AI characters
across every shot and engine.

Cast locks a brand or character identity once — a real, authorized actor or a stylized character — and holds it across every engine, shot, and cutdown. The face your client approves in the boards is the face in the final master.

The moat

Identity that holds by design, not by luck

Character consistency on VisionX isn’t a prompting trick. It’s an identity system — verified, guarded, and enforced before a single VX is spent.

A brand-locked identity

A Cast member is a real, authorized actor or a stylized character, held in an org-scoped roster — the Cast belongs to the studio, and only its members generate with it.

Consent, recorded per actor

A real person verifies themselves through a recorded face-validation consent flow — a liveness check on their own phone via QR link — before the identity can generate a single frame. That trail is what makes the output commercially usable.

Identity lives in the roster

A Cast reference resolves to the member’s verified assets at generate time. The identity a shot renders is the one the roster holds — not whatever URL happened to be in the prompt.

Characters without an actor

Paste or upload reference art, or generate a character in one click — a mascot or stylized spokesperson with no real person behind it. Same roster, same guard, same @-mention.

Face-match galleries

Every Cast member carries a primary portrait and a face-matched photo gallery. Every upload is checked against the verified actor — wrong-face and multi-face images are rejected before they can pollute the reference set.

@-mention, resolved server-side

Write @Aryan into the prompt and the platform resolves the identity server-side — the prompt itself never carries a face. Same mention, same character, whichever engine takes the shot.

The identity stack

Five layers between your brand and drift

Each layer locks a different surface of the identity. Together they’re why the face in shot 42 matches the face in shot 1.

Layer	What it locks	How it holds
Cast member	The face	A Cast reference resolves server-side to the member’s verified assets at generate time — the identity a shot renders is the one the roster holds.
Photo gallery	The reference set	A primary portrait plus a face-matched gallery — wrong-face and multi-face uploads are rejected before they can pollute the reference set.
Voice	The spoken identity	A cloned voice binds to the Cast member, so the character speaks with one voice in every deliverable.
Brand Memory	The world around the face	Reference plates, signature cinema-control keys, and the negative prompt apply in one click to shots, the composer, and templates — the Cast roster and style notes travel in the same portable bundle.
Consistency checker	The storyboard	A perceptual-hash pass flags identity drift across shots before the client ever sees the board.

The consistency checker is flagged as a v1 in the product — a perceptual-hash pass that catches the drift a tired eye misses on the tenth review. It sharpens a director’s judgement; it doesn’t replace it.

An @-mention resolves to the same identity wherever Cast references run — the Seedance 2.0 production tiers, the guest video engines, and every image route (Learning and Iteration cover Cast-free drafting). Because the identity lives in your Cast rather than in any single model, an engine changing or retiring never strands the character.

How it works

Roster to rendered shot, four moves

Build the Cast member

Add a real actor or generate a stylized character. Set the primary portrait and build the gallery — face-match enforcement keeps every reference on-identity.

Record the consent

For real people, the actor completes a face-validation liveness check on their own phone via QR link. Until that consent is recorded, the identity generates nothing.

@-mention in the shot

Write the character into any prompt with an @-mention. The platform resolves the identity server-side and routes the shot to whichever engine fits.

Check the board

Before client review, the cross-shot consistency checker flags identity drift across the storyboard — so the thirtieth cutdown gets the same scrutiny as the hero spot.

Why it matters

One face, every deliverable.

Agencies answer to brand books. A campaign is a hero film, thirty cutdowns, a stills library, and localized versions for every market — coherence across all of it is what the client is buying.

Included:The hero spot and all thirty cutdowns — one spokesperson, every cut.
Included:Stills, key art, and character sheets that match the film frame for frame.
Included:Localized versions where the same face delivers every market’s script.
Included:Two-character scenes that hold both identities in a single frame.
Included:Brand Memory in one click — plates, cinema-control keys, style notes, and the negative prompt travel with the Cast.
Included:Next quarter’s brief opens with this quarter’s character — the roster belongs to the org, not to a chat thread.

FAQ

Consistent characters, answered

How does VisionX keep AI characters consistent across shots?

Every generation binds a Cast — a brand-locked identity held in an org-scoped roster. Cast references resolve server-side to the member’s verified assets, so the identity a shot renders is the one the roster holds rather than whatever URL was pasted into a prompt. A cross-shot consistency checker then flags identity drift across the storyboard before a client ever sees it.

Can I build a consistent AI character from a real person?

Yes — with recorded consent. The actor completes a face-validation liveness check on their own phone via a QR link, and that consent is recorded per actor before the identity can generate anything. The authorization trail is what makes the output usable in commercial work.

Can I create a consistent character without a real actor?

Yes. A stylized Cast member starts from pasted or uploaded reference art, or from a one-click Generate character — a mascot or stylized spokesperson with no real person behind it. It lives in the same roster, resolves the same way at generate time, and uses the same @-mention workflow.

Do consistent AI characters work across different engines?

Yes — that is the point of Cast. You @-mention the character in a prompt and the platform resolves the identity server-side, so the same face renders whether the shot routes to the Seedance 2.0 production tiers (Standard and Cinema), a guest engine like Sora, Veo, Kling, or Grok, or any image engine. Consistency lives in the Cast, not in any one model.

Can the character keep the same voice too?

Yes. A cloned voice can be bound to a Cast member, so the character speaks with the same voice in every deliverable — the hero spot, the cutdowns, and the localized versions. Voice cloning and dubbing run in the VisionX Audio Studio.

What does it cost to run a campaign on one character?

Generation is metered in VX at $0.10 per VX list. A 5-second Standard shot at 720p costs 8.5 VX and a Seedream still is a flat 1 VX — the exact cost is quoted before every run. Every account starts with a free 100 VX trial, no card required; monthly plan allowances reset each cycle, and purchased top-up VX stays valid for 180 days.
