How to Keep Character Consistency in AI Video

Character consistency is the difference between a usable story clip and a noisy render. You need persistent anchors repeated across prompt sections.

Formula: [identity anchors] + [signature prop] + [camera constraint] + [emotion progression] + [continuity reminder].

1) Write fixed identity traits (face shape, eyes, hair). 2) Add outfit and accessory anchors. 3) Keep one camera transition. 4) Repeat anchors near end. 5) Render short test before longer sequence.

Noble Girl at Side Gate, braided hair, jade silk texture, lantern reflection on eyes.

Magical Girl Rooftop Reveal, same wand ornament and sleeve pattern across every frame.

Mistake: only describing identity once. Mistake: adding wardrobe change language unintentionally. Mistake: mixing two art styles in one prompt.

Sora: repeat identity anchors in closing sentence. Vidu: keep identity tokens short and literal. Kling: include body motion logic to avoid pose drift. Runway: use shot labels with anchor restatements. Veo: reinforce interaction consistency with environment props.
