An AI character that stays the same

The moment an AI character changes face between two scenes, the spell breaks and the audience leaves. Character consistency is the difference between a clip and a story — and it is a solved problem if you design characters as assets.

Create a portrait, not a one-off

Generate a clean character portrait in the character library first. That portrait becomes the reference for every scene the character appears in — same face, same outfit, same proportions, every time.

Describe them the same way every time

Keep one short written description per character — age, hair, clothing, vibe — and reuse it verbatim in prompts. Small wording changes produce small drift, and drift accumulates across scenes.

Reuse across videos

The library is the asset. A character built once can star in Express videos, Series episodes and Studio projects. Audiences bond with recurring characters — that bond only forms if the character never changes.

Takeaway

Portrait once, described identically everywhere, reused in everything — consistency is a system, not luck.
