In our main article, we explained how Gemini 3 Pro and Sora 2 work together inside PetMovie.ai to turn your pet photos into a Pixar-style 3D / CG short film.
But a modern "character IP" doesn't stop at video.
If you really love your dog or cat, you probably don't just want a movie. You want:
- A cinematic poster you can share or print
- A set of stickers / emojis so your pet can "speak" in your chats
That's where Nano Banana Pro comes in.
In this article, we'll walk through how PetMovie.ai 2.0 uses Nano Banana Pro as an AI poster generator and emoji maker to turn one pet movie into a small, shareable IP kit.
1. Quick recap: the core AI pet movie
If you haven't seen our full breakdown yet, here's the short version:
- Gemini 3 Pro analyzes your pet's photos and memories, builds a character profile, and rewrites one of our storyboard templates into a custom script about your pet
- Sora 2 turns that script into a set of short, cinematic clips in a Pixar-style 3D / CG aesthetic
- Our pipeline stitches those clips together with subtitles and music into a complete AI pet movie

Once that core film exists, we can start asking a new question:
"What else can we create from this story and these visuals?"
Enter Nano Banana Pro.
2. What is Nano Banana Pro, in simple terms?
You can think of Nano Banana Pro as:
An image generation and editing model that's particularly good at clean visual design, text, and layout.
Unlike generic "text-to-image" tools that sometimes struggle with typography and consistency, Nano Banana Pro is designed for:
- High-quality still images (great for posters and thumbnails)
- Accurate, legible text on top of images (titles, taglines, names)
- Reasonable control over layout and style, guided by prompts and reference images
For PetMovie.ai, that makes Nano Banana Pro the perfect candidate to be:
- Our pet movie poster designer
- Our sticker / emoji art director
3. Turning your AI pet movie into a cinematic poster
Let's start with the poster.
Step 1 — Picking the key moment
After your movie is generated, PetMovie.ai 2.0 will automatically scan it for:
- The most emotionally intense frame
- Or the most visually iconic shot (for example, your dog framed by Christmas lights, or your cat sitting in a sunbeam)
We can also let you manually pick a frame if you prefer a specific moment.
Example: A cinematic poster generated from a pet movie
Step 2 — Feeding Nano Banana Pro a "poster brief"
We then send Nano Banana Pro:
- The selected frame (or few frames) as visual references
- A short poster brief, for example:
"Create a cinematic movie poster for a heart-warming Christmas hero dog story. The title is 'My Little Hero'. The pet's name is 'Max'. Style: Pixar-style 3D / CG, soft lighting, clear golden title text."
From this, Nano Banana Pro generates multiple poster variations, each:
- Centering your pet as the main character
- Keeping a consistent 3D / CG look that matches the film
- Arranging the title, subtitle and name in a readable, film-like layout
Step 3 — Output sizes and uses
We plan to offer a few practical outputs:
- Phone wallpaper size (vertical)
- Story / Reel cover size (9:16)
- Social post / print-ready size (4:5 or 3:2)
You'll be able to:
- Share the poster as a standalone piece on social media
- Use it as a cover image for the movie
- Print it as a physical keepsake if you like
In short, Nano Banana Pro turns your AI pet movie into something that looks like a real film release poster — but starring your dog or cat.
4. From movie frames to 8–12 custom pet emojis
The second part of PetMovie 2.0 is all about stickers and emojis.
We want your pet to be able to "show up" in your chats, not just in a video player.
Step 1 — Finding the best expressions
Our system scans your pet movie for:
- Big emotional beats (joy, surprise, determination, gentle sadness)
- Clear, readable facial expressions and poses
Capturing expressive moments from the movie for emoji creation
Think:
- The proud "I saved you" look
- The confused head tilt
- The full-body zoomies moment
- The tiny, sleepy eye squint
From these, we select 8–12 frames that could work as stickers.
Step 2 — Stylizing with Nano Banana Pro
We then feed Nano Banana Pro:
- The chosen frames as inputs
- A style brief such as:
"Turn each frame into a clean, fun sticker. Keep the dog clearly recognizable. Use a consistent outline and color style. Transparent background. Ready for chat apps."
Nano Banana Pro outputs a set of cohesive sticker-style images, each:
- Centered on your pet
- Cleanly cropped
- Harmonized in style (same line width, shading, outline, etc.)
Step 3 — Packaging as a sticker / emoji pack
Finally, we package these 8–12 images into a simple format you can import into:
- WhatsApp / Telegram sticker packs
- iMessage sticker apps
- Other platforms that support custom emojis or stickers
The end result: instead of generic dog emojis, you're reacting in chats with your dog's actual face, taken from their AI movie.
5. Real-world examples
Here are some examples of different story types and visual styles you can create:
A cat hero story that could generate multiple poster variations
An adventure story with wide-angle poster potential
6. Why Nano Banana Pro instead of any random image model?
There are many image models out there. We're betting on Nano Banana Pro for a few reasons:
- It's tuned for clean text and layout, which matters a lot for posters
- It plays well with the same kind of prompts and context we already use with Gemini 3 Pro
- It can respect visual consistency across a set of images, which is crucial for emoji packs
Most importantly, it fits our long-term vision:
One consistent visual universe for your pet — across video, posters, and stickers.
7. How to get ready for PetMovie 2.0 now
The good news: you don't need to wait for PetMovie 2.0 to start.
Everything from Nano Banana Pro — posters and emojis — will be built on top of your existing AI pet movies.
So the best way to prepare is:
- Create your first AI pet movie on PetMovie.ai using Gemini 3 Pro and Sora 2
- Pick a storyboard that really fits your story (hero, memorial, reunion, daily life)
- Save or bookmark the movie you love most
When PetMovie 2.0 launches, use that film as the base to generate:
- A cinematic poster
- An 8–12 image sticker / emoji pack
