The Nano Banana image generator
Every video starts as images, and image quality compounds: a strong portrait makes every scene with that character better. Nano Banana is the image model for building those reusable assets.
Build character sheets first
Before generating scenes, generate the cast: clean portraits, consistent style, distinct silhouettes. These portraits feed the character library and anchor every future video.
Generate scenes at final aspect
Generate in the aspect ratio the video will use — vertical for feeds. Rerendering a landscape image into vertical costs quality; starting vertical costs nothing.
Fix images before animating
A video model animates whatever you give it, flaws included. Spend a cheap image regeneration to fix a hand or an eye before spending video credits on animating a broken frame.
Takeaway
Portraits first, vertical by default, and fix images before they become videos.
