NotebookLM Video Overviews add Nano Banana visual styles, Brief or Explainer formats

After introducing in July, NotebookLM is giving Video Overviews a big upgrade with the help of Google’s Nano Banana image editing and generation model (Gemini 2.5 Flash Image). 

You can now choose from one of two Video Overview formats:

  • Brief: A bite-sized overview to help you quickly grasp core ideas from your sources
  • Explainer: A structured, comprehensive overview that connects the dots within your sources

Meanwhile, NotebookLM is now using Nano Banana to offer six new visual styles for your video: Whiteboard, Watercolor, Retro print, Heritage, Paper-craft, and Anime. 

Classic remains available as the original style, with an “Auto-select” option offered if you don’t want to choose. In generating “helpful, contextual, and beautiful illustrations based on the sources you upload,” Google wants to “help you understand and remember them.”

Select the pencil icon in the Video Overview tile of the Studio panel. These two new options join language customization and the prompt box that lets you focus the AI hosts on specific sources, use cases, and structure.

These two updates are rolling out first to NotebookLM Pro users (Google AI Pro) this week. It will be available to all (free) users in the coming weeks. 

On the Nano Banana front, Google today made official the AI Mode and Lens integrations, while it’s coming to Google Photos “in the weeks ahead.”
