Character consistency
Character consistency means a person in a video looks recognizably the same in every scene: the same face, build, hair, clothing and age.
Why it matters
If someone's face changes from scene to scene, viewers stop being sure who they are watching. In a documentary about real people, it also undercuts trust in the story.
AI makes each picture fresh, so the same description can produce a slightly different person every time. Across a story those small changes add up: a jaw gets wider, a coat changes color, a person suddenly looks years older between two scenes.
Careful makers settle one approved look first, draw every scene from it, and keep clothing and details fixed unless the story says they change. If a person ages across the story, that change is planned, not left to chance.
For a real person, the approved look should be checked against real photographs, and viewers should understand that it is an illustration, not a photograph of them. Every finished shot is then checked by eye against the approved look.
A short follows a scientist from her first lab job to an award forty years later. Her look is approved at two ages and each scene is drawn from the right one, so she ages once, on purpose, instead of drifting from shot to shot.
How we use it
When a real person appears in several scenes, we approve one look for them first, and every scene that shows them is drawn from that look.
