Google has added a feature to its AI research tool NotebookLM that automatically condenses uploaded material into roughly 60-second vertical videos, extending the tool’s content-generation capabilities beyond text and audio to short-form video.

Announced June 30, the feature, called Short Video Overviews, uses AI to analyze documents, notes and web sources uploaded by users and summarize the key points into vertical clips of about a minute, according to 9to5Google. The videos combine AI-generated images and animations with narration and are designed to let users grasp long documents quickly — built, in Google’s framing, to be watched on a phone like a social-media story.

The Latest Format in a Growing Tool

NotebookLM began as a research tool centered on document summaries and question-and-answer. It has since added AI podcasts, cinematic video, visual explanations and now short-form video, growing into a platform that spans text, audio and video. Short Video Overviews builds directly on the existing Cinematic Video Overviews: where the earlier format produced longer, explanatory videos, the new one is meant to compress only the essentials for fast comprehension.

To create a video, users select a source in NotebookLM, open the Studio panel, choose the video output and set the format to “Short,” alongside the longer Cinematic option. The feature is launching first in English, and Google said it expects it to be used for student review, research summaries, enterprise document sharing and educational content.

Who Can Use It

Subscribers to the Google AI Ultra and Pro plans can use Short Video Overviews now on the web and mobile, and Google said it will extend access to free-tier users in the coming weeks. Google also notes the feature is limited to users 18 and older. As with the earlier video formats, the rollout is expected to take some time, and clips are generated in English at launch.

The Models Behind It

The clips are generated by Nano Banana 2 Lite, a lightweight image-generation model Google unveiled the same day. Officially named Gemini 3.1 Flash-Lite Image, it is what Google calls its fastest and most cost-efficient image model, producing an image in about four seconds — cheap and fast enough to string many frames into a short clip. Google positioned it as the successor to the original Nano Banana and released it to developers alongside its consumer debut, threading it into products from Search’s AI Mode to Google Photos.

Google also previewed a separate video-generation model, Gemini Omni Flash, the same day. That model, aimed at generating and conversationally editing short video clips, already powers part of NotebookLM’s video features; Short Video Overviews leans on the faster image model to keep the clips quick and inexpensive to produce.
