Art direction for AI video: building the visual bible of a universe
Tools change every six months. What holds a series together over time is not the model: it is the art direction, decided before the first generation. Without it, every shot is beautiful and the whole looks like nothing.

Why a visual bible
An AI model pulls every image towards its average: saturated colours, flattering light, textures that are too clean. Without fixed instructions, your shots each drift their own way. The visual bible is the document that brings every generation back to the same universe. It fits on one page, and it no longer changes once the series has started.
Close the palette
Choose five or six colours, named by their material rather than a code: that is how a model understands them best. The whole Archives laboratory fits into five shades:
- matte white panels;
- burgundy enamel;
- brushed steel;
- laboratory glass;
- aged paper and leather.
Anything outside the palette stands out at once. That is the point: a stray colour becomes a warning sign, not a detail.
Choose your materials once and for all
Texture gives AI away faster than shape: a plastic look, resin skin, metal without wear. Decide which materials exist in your universe, how worn they are, and write it down. Add an "anti-plastic" instruction to every prompt: matte surfaces, micro-relief, signs of use.
A vocabulary of light
A time of day, a direction, a temperature, and an identifiable main source: a sign, a window, a lamp. Keep the same words from shot to shot. If the light changes, it is because the story demands it, not because the model decided so.
Write down what is forbidden
A visual bible also says what does not exist in the universe: the shapes, colours and effects to reject. This list is often more useful than the description itself, because it is what lets you throw a shot away without hesitating.
One set sheet per location
For each recurring location, prepare a reference sheet: the zones of the place, from several angles, in the closed palette. A set is treated like a character: a reference image, a fixed description, and no retouching once production has started. The method is covered in the guide on character consistency.
Check the series, not just the shot
Regularly lay all your shots side by side as thumbnails. A shot that works on its own can be wrong within the series: too warm, too clean, too saturated. Final colour grading brings shots closer together, but it cannot rescue a palette that was never fixed.
