How to prompt Nano Banana 2 for consistent characters
By the FXI Studio team · Updated
Nano Banana 2 is an image model that excels at fast, clean, well-composed stills and at holding a character consistent across many frames when you feed it reference images. Attach one or more references, describe the same subject in the same words each time, and it keeps the identity locked across a whole storyboard.

“Character reference sheet, neutral studio grey. An auburn-haired bicycle courier in her late twenties, light freckles, an olive canvas field jacket over a grey henley. Three views on one frame: front, three-quarter, profile. Even soft key light, consistent proportions, photoreal.”

Every strong prompt is built, not written.
| References | Attach 1–14 reference images. A clean front portrait plus a contact sheet locks identity hardest. |
|---|---|
| Subject phrasing | Describe the character with the SAME words every frame — "auburn-haired courier, freckles, olive field jacket". |
| Scene | Change the setting and action per frame; keep the subject description word-for-word identical. |
| Composition | Name the shot — "medium two-shot", "over-the-shoulder" — so the storyboard reads as coverage. |
| Resolution | 1K for drafts, 2K–4K for finals. Draft the whole board at 1K, then re-render keepers. |

Character sheet
Lock a face before you build the story around it.
Character reference sheet, neutral studio grey. An auburn-haired bicycle courier in her late twenties, light freckles, an olive canvas field jacket over a grey henley. Three views on one frame: front, three-quarter, profile. Even soft key light, consistent proportions, photoreal.
- Build the sheet first — it becomes your reference for every later frame
- Neutral background and even light keep the identity clean
- Reuse this exact character description verbatim in every downstream prompt
Storyboard frame (with refs)
Same character, new scene — identity held.
Cinematic still, medium shot. [Image1] the same auburn-haired courier with freckles in her olive field jacket, now walking a rain-slicked cobblestone alley at dusk, string lights overhead, warm amber pools on wet stone. Shallow depth of field, filmic grade. Keep her face and wardrobe identical to the reference.
- Attach the character sheet and reference it as [Image1] in the prompt
- Change only the setting and action — never the subject wording
- End with an explicit "keep face and wardrobe identical" instruction
Product hero still
A clean, well-composed commercial frame.
Product hero still, 4:5. A ceramic pour-over coffee dripper in matte sand-beige on a sunlit linen surface, a single stem of dried wheat casting a soft shadow across the frame. Late-morning window light from frame-right, airy negative space top-left for a headline. Editorial, minimal, photoreal.
- Reserve negative space if you plan to add a headline later
- Name a single light direction for believable shadows
- Nano Banana 2 composes cleanly — trust it with minimal, editorial layouts
Common failures, and how to unlock them.
The character drifts between frames.
Attach the reference sheet, cite it as [Image1], and reuse the exact same subject description word-for-word.
Faces look subtly different each render.
Add a clean front portrait to your references and lock lighting to "even soft key" on the reference sheet.
Composition feels cramped.
Name the shot type and reserve negative space explicitly if a headline is coming.
Output is too illustrated.
Add "photoreal" and a lens/grade cue to bias toward photography.
A single prompt is a clip. The workflow is the film.
The real leverage is in the pipeline between generations — keeping one character across every shot, and frame-chaining each clip’s last frame into the next so a storyboard becomes one continuous move. That is a built-in FXI Studio capability.
