Cinematic prompting: keeping characters, light and lenses consistent
The short answer: consistency across AI shots comes from a reference system, not from better luck. Name every recurring entity, freeze a style block you paste verbatim into every prompt, and anchor scenes with reference images or start frames whenever the tool allows it.
Why do characters drift between shots?
Every generation starts from noise. If your description of the character varies — “a woman in a coat”, then “the woman”, then “a figure” — the model re-invents her each time. Drift is not a model failure; it is a script supervisor failure. The fix is the same discipline continuity people have used for a century: write it down once, repeat it exactly.
What goes in a style block?
- Film stock and era: e.g. “1950s black-and-white 35mm film, fine grain, deep blacks”.
- Lens language: focal length feel, depth of field, vignetting.
- Light: one dominant source per scene, named (“the neon sign”, “the moon”).
- Palette discipline: what colors are allowed to exist — ours is black, silver-white and one neon accent.
- Negative space: what must NOT appear (logos, text, modern cars).
How do reference images change the workflow?
They turn prompting from description into casting. Generate a character sheet first — front, profile, expressions, wardrobe — then feed the same sheet to every shot of the sequence. When a model supports start and end frames, storyboard in stills first and let the video model interpolate performance between fixed images. You are no longer asking for a person; you are directing an actor you already hired.
What breaks consistency even with references?
- Changing aspect ratio mid-sequence — reframe in the edit instead.
- Mixing model versions within one scene.
- Prompting emotion abstractly (“sad”) instead of physically (“shoulders down, eyes on the floor”).
- Regenerating a whole shot when only the last second fails — trim and extend instead.
A prompt is a call sheet. Write it once, shoot it many times.
QUESTIONS & ANSWERS
- How do I keep the same character across AI-generated shots?
- Create a character sheet (front, profile, expressions, wardrobe), name the character, and reuse both the sheet as reference and the exact same descriptive wording in every prompt of the sequence.
- What is a style block in AI video prompting?
- A frozen paragraph describing film stock, lens language, light and palette that you paste verbatim into every prompt of a project, so every shot shares the same visual DNA.
- Why does my AI video look different in every shot?
- Because each generation starts from noise and your prompts vary. Fix the wording, fix the references, fix the aspect ratio and model version, and the shots will hold together.
