Key takeaways

Nano Banana 2 is a practical candidate when your workflow needs image-to-image editing, text-to-image generation. Start with the simplest enabled input mode, keep the first test small, and compare results with the same prompt and source material before committing to a longer production run.
Enabled modes: image-to-image editing, text-to-image generation.
This guide covers Nano Banana 2 AI image generator and the enabled input modes.

Is Nano Banana 2 the right model for this workflow?

Nano Banana 2 is a practical candidate when your workflow needs image-to-image editing, text-to-image generation. Start with the simplest enabled input mode, keep the first test small, and compare results with the same prompt and source material before committing to a longer production run.

A useful comparison keeps the prompt, input asset, aspect ratio, and review criteria constant. Change only the model. That gives you evidence about fit instead of a misleading comparison between different creative briefs.

What Nano Banana 2 supports in Videu AI

The current Videu AI catalog exposes the following modes. Each mode starts from a different kind of input, so choose the one that preserves the part of your idea that is already decided.

Image to image

When to use it: Use image to image when you need a controlled variation or edit while keeping important parts of an existing asset.

Prompt focus: Name the elements to preserve before describing the edit. Separate content changes from style changes when you need predictable comparisons.

Review: Check preserved areas first, then look for unintended replacements, edge artifacts, color shifts, and changes to the original framing.

Text to image

When to use it: Use text to image to explore a composition from a written brief before you have a reference asset.

Prompt focus: Specify the subject, composition, environment, lighting, visual treatment, and intended use. Add constraints only when they affect the final asset.

Review: Inspect subject anatomy or object geometry, focal hierarchy, text rendering, edge quality, and whether the composition fits its intended placement.

Provider capabilities and limits can change. This page intentionally reports the modes currently enabled in Videu AI instead of making unsupported claims about resolution, duration, or quality.

How to prompt Nano Banana 2 for a first test

Start with a brief that is easy to judge. A first prompt should describe the result, not every possible detail. Use this order, then remove any field that does not affect your goal:

1. Subject
2. composition
3. environment
4. lighting
5. visual treatment
6. final use or aspect requirement

Run the shortest representative test your workflow allows. If the result misses the brief, identify whether the input, prompt, or model caused the mismatch before adding more instructions.

Good use cases for Nano Banana 2

Create a still image from a structured prompt for concepts, thumbnails, and campaign assets.

Iterate on an existing image while preserving the parts of the composition that matter.

A practical workflow

1. Define the asset job. Specify where the image will be used, what must be visible, and which composition constraints matter.
2. Choose text or reference input. Use text for open exploration and image input when an existing subject or layout must remain recognizable.
3. Change one variable. Separate composition, content, and visual treatment changes so comparisons remain meaningful.
4. Save the reproducible version. Keep the prompt, selected model, and source image for the version that meets the brief.

What to check before using the result

A result can look impressive and still fail its actual job. Review it at normal playback or display size, then inspect the details that matter to the destination:

Subject or object geometry
Composition and focal hierarchy
Text legibility when text is requested
Edges and background details
Fit for the intended placement

Record the prompt, source asset, and selected model for the version you keep. That makes the next iteration reproducible and prevents a good result from becoming an unrepeatable accident.
