Character bibles

What a bible is

A bible is one locked paragraph that defines a character: face, hair, age, body type, wardrobe, jewelry, voice, and posture. It is injected unchanged into every video prompt, which is what keeps her the same person across clips.

Create a character

Either let the Character Builder write the bible from a few inputs (costs 5 credits), or send your own.
