Nano Banana 2.1 Character Creation Guide: Preparing More Consistent Visual Design for AI Shorts

The protagonist of an AI short film may need to appear on an early-morning street, in a dimly lit interior, and in a crowded station. The scenes keep changing, but the audience still needs to recognize that this is the same person. For creators, a character’s face, clothing, and signature details are important clues that connect different shots. The clearer the preparation is in the early stage, the more basis there will be for selecting and revising images later. The capabilities described for Nano Banana 2.1 align well with this kind of creative need.

Why should character creators pay attention to Nano Banana 2.1?

According to nanobanana.io, Nano Banana 2.1 is designed for image generation and editing, with an emphasis on using reference images to guide character appearance and visual style, and on modifying details such as clothing and backgrounds through natural language. The page also notes that different results may still vary, and this version is currently marked as “coming soon.” For AI short-film creation, the page introduction offers an approach worth trying: first define the character’s basic look, then explore variations around the needs of the story. The following methods can serve as creative preparation after the model becomes available, and they are also useful for organizing existing character materials.

Start with a character reference that can be reused

Suppose you want to make an urban short film about a young photographer. You can first define several identifying traits: shoulder-length short hair, a dark blue jacket, a crossbody camera bag, and an expression that looks slightly tired but focused. The purpose of the base reference image is to make these traits clear. When preparing it, you can prioritize images where the face is unobstructed, the clothing silhouette is complete, and the lighting makes details easy to observe. At the same time, write a brief character description that separates two types of information: - Fixed settings: appearance traits, usual clothing, and signature accessories. - Story changes: expression, action, clothing condition, and environment. This way, when designing a rainy-night shot, it is clear that “the jacket is wet from the rain” belongs to the story changes, while “the jacket color and camera bag style” should be carried forward.

Give a clear visual goal for every revision

When iterating on character images, requesting too many changes at once makes it harder to judge the results. A clearer approach is to make specific requests around the current shot. For example, the following is an original editing prompt that can be used for testing: Keep the facial features, hairstyle, dark blue jacket, and camera bag of the reference character. Change the scene to a bus stop after the rain. The character is looking down at the camera, with a quiet and focused mood. Use soft streetlights in the background and avoid blocking the character’s face. This kind of description explains both what should change and which elements need to be preserved. When reviewing the result, you can compare it point by point instead of deciding whether to use it based only on the overall impression.

In NadouPro, place character references back into the story

After the character image is defined, it still needs to be connected to the specific plot. NadouPro’s Workbench organizes projects by script, subjects, storyboards, and production, and supports managing characters, scenes, props, and related states. Creators can organize confirmed designs into the production process and prepare corresponding character references for different story moments. The same photographer may need completely different actions and emotions across the three stages of “searching for a subject,” “discovering an important clue,” and “deciding to leave.” Arranging materials around the plot is more likely to serve later shot production than simply accumulating a large number of attractive portraits.

For storyboard preparation, check the relationships between images

When character materials enter the storyboard stage, you can focus on checking character position, line of sight, prop status, and lighting changes. For example, if the character is holding the camera in the right hand in the previous shot, is it still reasonable in the next shot? If the character is looking toward the left side of the frame, does the following shot respond to that gaze? These details determine whether the images can connect smoothly. NadouPro supports editing storyboard descriptions, order, and subject references, making it easier to turn these judgments into shot arrangements before gradually advancing image or video material production. The focus brought by Nano Banana 2.1 can become an opportunity to reorganize character creation methods. Prepare a clear visual design first, then enter NadouPro to organize the story and shots, so the character maintains a recognizable image and continuous emotion across different scenes.
