Keeping Characters Consistent Across AI Video Scenes

Start with a reference, not a longer prompt

Character drift is rarely fixed by adding another paragraph of adjectives to every prompt. The reliable starting point is one approved reference frame: a front-facing shot with the hairstyle, clothing, colors, and key accessory clearly visible. Use the same reference on every scene that must portray the same person.

Write down three or four visual anchors that do not change. For example: a navy work jacket, round silver glasses, short dark hair, and a canvas tote. Repeat only those anchors in each scene prompt. Everything else can change around them: location, camera angle, action, lighting, and pacing. This separation gives the model a stable identity while leaving room for the scene to do its job.

Treat every scene boundary as a handoff. The final frame of the previous clip should be compatible with the opening instruction of the next one. If the character exits left in a bright studio, do not start the next prompt with a dark outdoor close-up and expect the model to preserve every detail. Use a bridging shot, keep the wardrobe explicit, and change one major variable at a time.

For a product video, keep the character notes in a reusable block and the product notes in a separate block. That prevents a new product color or background from accidentally replacing the character’s visual identity. Review the first two clips before generating a full sequence; correcting drift early is far cheaper than rebuilding a finished edit.
