Google NotebookLM Short Video Overviews: 60-Second AI Clips Powered by Nano Banana 2 Lite

A New Way to Digest Your Research

Google has added a third video format to NotebookLM's Studio panel: the Short Video Overview. This is a 60-second, vertical (TikTok-style) AI-generated video that summarizes the documents, notes, and sources you upload to a notebook. Think of it as a fast, visual alternative to the existing Audio Overviews — ideal for quick catch-ups without reading through pages of text.

Key Feature Details

Format and Duration

This is the third video format in NotebookLM's Studio. The official Google Help page now lists three formats: Cinematic, Explainer, and Short . (The "Brief" format was briefly mentioned in earlier reports but has since been superseded by the official naming.)

Customization Options
