How to Keep a Character Consistent Across AI Video Clips Using Reference Images

Описание и применение

В статье описывается пошаговый рабочий процесс, позволяющий сохранять постоянный вид персонажа в нескольких AI‑видеоклипах, используя изображения‑ссылки, корректные подсказки и пост‑обработку.

Задача

AI video clips often show the same character with inconsistent appearance across shots, causing visual drift.

Результат

Following the workflow reduces character drift, enabling coherent short stories, product ads, or social clips with recurring mascots.

Рабочий процесс

• Build a clean character sheet with plain background, 2–3 angles, and fixed signature details.
• Write prompts that describe the scene and camera, not the character, and reuse a short anchor phrase.
• Generate clips with reference‑to‑video, paying attention to clip length, camera motion, and aspect ratio.
• Keep a shot log to track prompts, references, and outcomes.
• Repair near‑miss shots with character replacement passes.
• Extend existing clips from the last frame instead of restarting generation.
• Assemble and smooth cuts with motion cuts, varied shot sizes, and unified color grading.

Доказательства

If you have tried to make anything longer than a single AI video clip, you have probably hit the same wall: the character in shot one is not quite the character in shot two.

Reference-based generation changes the input: instead of only describing the character, you give the model one or more images of the character and ask it to place that character into a new scene.

Cut on motion. A cut in the middle of a movement hides small differences between shots.
