Nano Banana 2.1 Prompt Guide: Four Practical Workflows
Nano Banana 2.1 creates images you can revise before animating. Google describes improvements in text rendering, prompt adherence, and character consistency across edits. These are Google’s claims, not our benchmark results. The prompts below are suggested starting points; we have not tested them. Google’s model documentation identifies the stable model as gemini-nano-banana-2.1.
For a PixVerse workflow, aim for an approved first frame: a clear product, readable composition, or consistent character. Check the still first, then upload it for image-to-video.
Set the Controls Before Writing
Google documents 1K, 2K, and 4K output, with 1K as default. Thinking levels are minimal, medium (default), and high. Choose resolution and thinking through the controls your Google interface or API exposes; writing “4K” in a prompt does not establish that setting. Model specifications.
The 512px option from Nano Banana 2 is unsupported in 2.1. Google’s API settings are also distinct from settings visible in other platforms. Image-generation documentation.
Separate the desired result from details that must stay fixed. Give each reference image an explicit job.
1. A Product Photo With Clear Constraints
Attach a clean product photograph. Start with one composition that will leave room for captions in your finished video.
Use the attached bottle as the product reference.
Create a studio photograph of this exact bottle on a pale stone surface.
Preserve its shape, cap, label placement, and color.
Place the bottle in the right third; leave the left third uncluttered.
Soft daylight from the left, subtle contact shadow, realistic glass.
One bottle only. No added props or invented text.
Follow-up edit:
Change only the backdrop to muted sage green.
Keep the bottle, label, camera angle, position, and lighting unchanged.
Compare the output with the source photograph. Check the cap and label. If precise branding matters, retain the original label in final editing rather than relying on regeneration.
2. A Poster With Short, Literal Text
Verify text even with Google’s reported improvement. Short copy and an explicit hierarchy make review manageable.
Create a minimal poster for a neighborhood coffee event.
Render these exact strings, once each:
Headline: “COFFEE CLUB”
Subtitle: “SATURDAY 10 AM”
Large dark headline at the top, smaller subtitle directly below.
One ceramic cup in the lower half. Cream background, clear margins.
No other letters, numbers, logos, or decorative text.
Follow-up edit:
Increase the subtitle size and darken it for readability.
Keep both text strings exactly as written.
Preserve the cup, background, headline placement, and margins.
Read every character at the intended viewing size. For multilingual campaigns, review each language separately; correct English spelling does not establish correct localized typography. Add final campaign copy in an editor when accuracy must be guaranteed.
3. Character Frames for a Storyboard
Use a clearly named character reference and generate individual shots. Google’s documented ceiling is 14 reference images, with support for up to four characters and ten objects; it is not a guarantee that every detail survives each edit. Reference-image limits.
Reference A defines the courier’s face, hairstyle, and yellow raincoat.
Create one storyboard frame: the courier stands outside a small bakery
at dawn, holding a blue delivery bag. Medium shot at eye level.
Preserve Reference A’s identity and clothing details.
Warm window light, damp pavement. No extra people or text.
Next shot:
Create the next frame: the same courier steps toward the bakery door.
Keep the face, raincoat, bag, weather, and bakery design consistent.
Change the framing to a close shot of the upper body.
Check face shape, coat fastenings, and bag straps across frames. Keep the last approved image available as a reference if the sequence drifts. A storyboard is a planning asset; these frames do not constitute generated video.
4. A Wide Composition With Usable Empty Space
Google reports fixing tiling artifacts at 2K and 4K for panoramic ratios including 4:1 and 8:1. Treat that as a release claim and inspect your own output. Wide-image update.
Create one continuous coastal landscape at sunrise.
Put a lighthouse in the left quarter and open ocean across the right.
Keep the horizon continuous with one consistent camera perspective.
Leave the upper-right sky clear for later campaign text.
No panels, repeated scenery, borders, or lettering.
Select the supported ratio and resolution separately. Inspect horizon seams and repeated objects. For video, plan a composition that also works at the delivery ratio instead of cropping the lighthouse away afterward.
Approve the Still, Then Animate in PixVerse
Nano Banana 2.1 generates images, not video. This guide does not establish its availability inside PixVerse. Export an approved still from your image tool and upload it to PixVerse for image-to-video.
Start with a restrained motion brief: “Slow camera push toward the bottle. Soft light stays consistent. No new objects or text.” Review motion for product distortion and lettering changes before producing more variants. For exact titles, overlay them during final editing.
