Keeping a character consistent

Each generation starts fresh, so a character described only in words will look a little different every time. The reliable fix is a reference image.

#The basic method

1. Create or choose a main image of your character. A clear, front-facing picture with even light works best.
2. Switch to an Edit model: Nano Banana 2, Nano Banana Pro or Nano Banana Lite. Only these accept reference photos.
3. Add the main image as a reference. Open it and click Edit this image, or upload it (up to 3 photos, JPG/PNG/WebP up to 10 MB).
4. Describe the new scene and say what should stay the same.

Keep the same character from the reference: same face, same red curly hair, same green jacket. Now she is sitting in a cafe by the window, reading a book, soft afternoon light.

#Tips

• Write a fixed description of the character (hair, eyes, clothes, age, style) and paste it into every prompt.
• Use the same reference every time. Chaining edits of edits can slowly drift.
• Add a second reference for something that must stay exact, like an outfit or a logo. Say which photo is for what.
• Keep the style the same. Switching from photo to anime changes more than you expect.
• Use Nano Banana Pro for faces when realism matters most.

#In Tyzli Movies

On the canvas, connect one Photo or Image block with your character to every Image block that makes a key frame. Each frame then uses it as a reference. See Canvas blocks reference.

The Character highlight template (16:9) is built for this: upload a photo of a character or a pet and it builds shots around it.
