In V2 (single subject with optional dialogue and separate narration) and V3 (two-person dialogue), the "Subject" field lets you describe each character’s appearance and traits. Using the same description across shots helps the AI keep the same character consistent in your video.
A short "character brief" of around 200 characters—age, build, hair, clothes, overall impression—works well. Keep it in your script or notes and copy-paste whenever you need that character again.
For **three or more people** in one shot, use **V4** (Premium): separate appearance fields for subjects A–E. See the **V4 Shotlist** block on this page or the AI features page for the full walkthrough.
Example: AI character prompt (e.g. Have AI describe a film character in one sentence, ~200 chars: race, age, build, hair, clothes, impression—like “…appearance of Tom.”)
Tom: a 32-year-old white man, 185cm, solid build, short blond buzz cut with neat stubble, sharp blue eyes, wearing a navy bomber jacket over a clean white plain T-shirt, broad shoulders and a defined jaw—an active, strong presence.
V3: Assign dialogue and optional action beats to the right character
In V3, each subject has appearance, on-screen dialogue, and an optional **Action** field (action-only → leave dialogue empty, or a simultaneous beat split from the line). That reduces mix-ups about who speaks. Talk-while-doing can stay in dialogue with a parenthetical, or split across dialogue + action; **if both are filled**, the app merges **(verb)line** inside quotes. Do not duplicate the same beat in both fields.
