How to keep the same AI character across images and video

Identity consistency is a hierarchy

Face shape, feature spacing, hair, skin tone, age cues, and body proportions matter more than wardrobe or background. Put those immutable traits first, then describe the scene transformation.

A reliable generation order

Start with neutral, readable references and prove the identity in simple scenes before pushing into extreme editorial lighting or fantasy styling.

• Choose a sharp front or three-quarter portrait with natural texture.
• State the identity preservation instruction before scene language.
• Generate controlled variations and keep only recognizable results.
• Use approved outputs as additional references for difficult angles.
• For video, animate the strongest still instead of regenerating identity from text.

Common failure patterns

Overloaded prompts often preserve the costume while losing the face. Heavy beauty language can also smooth away the specific imperfections that make a person recognizable. Reduce style pressure before adding more identity adjectives.
