Video Overviews on NotebookLM get a major upgrade with Nano Banana

Dense documents can be challenging. NotebookLM helps you understand any sources you upload and today, that process becomes better — and more fun, too.
We’re rolling out a major upgrade to Video Overviews, our feature that instantly turns your notes and documents into narrated videos. Using Gemini’s image generation model, fondly known as Nano Banana, our new update gives you more options for how Video Overviews look and feel.
A creative boost with Nano Banana
Nano Banana in NotebookLM generates helpful, contextual, and beautiful illustrations based on the sources you upload. The result is Video Overviews that don't just tell you about your documents — they help you understand and remember them.
New Video Overviews will automatically use one of six new visual styles: Watercolor, Papercraft, Anime, Whiteboard, Retro Print and Heritage.

Two ways to watch
Sometimes you need a detailed summary from a Video Overview. Other times, you just need the highlights. NotebookLM now offers two formats to meet both needs.
- Explainer: A structured, comprehensive video based on your sources for in-depth understanding.
- Brief: A new, bite-sized video format to help you quickly grasp the core ideas of a document.
To create the new video overview:
- Select your sources in NotebookLM and click the "Video Overview" button.
- To customize your video, select the pencil icon on the Video Overview tile.
- Choose between the format, visual style and try customizing the video, like "Focus only on the cost analysis sections of the business plan." or "Convert these recipes into an easy-to-follow video focusing on the prep time and cooking steps."
- Sit back and explore your notebook while the video is being generated.

This update continues our work to make information more accessible and useful by transforming dense information into dynamic multimedia that helps people understand complex topics in new ways.
The new Video Overviews will start rolling out in all supported languages to Pro users this week and to all users in the upcoming weeks.
