Google’s research tool, NotebookLM, is getting a new feature called “Short Video Overviews”: 60-second portrait-oriented videos that explain a single concept based on your uploaded sources. Visually, the whole thing resembles an Instagram Story or a Reel; in terms of content, it’s like a concise explanatory clip. The rollout began on June 30, 2026.
The key feature: The videos are automatically generated from your documents, PDFs, or notes. Explanatory animations are paired with an AI narrator, similar to the already familiar Cinematic Video Overviews—only much shorter and designed for mobile devices. Google is promoting the feature with the tongue-in-cheek slogan “Doom scrolling, but make it educational.”
The key points at a glance:
- Short Video Overviews are 60-second vertical videos that summarize a concept based on your sources.
- The rollout began on June 30, 2026, initially for Google AI Ultra and Pro subscribers on mobile and the web.
- Free users will get the feature later; Google hasn’t specified an exact date yet.
- Technically, the new models Nano Banana 2 Lite and Gemini Omni Flash are behind this.
- At launch, the feature is available only in English; additional languages are expected to follow in the coming weeks.
What Short Video Overviews Can Do in NotebookLM
You upload a source to your Notebook—such as a PDF, a Google Doc, or a webpage—and NotebookLM turns it into a one-minute clip on a single topic. The format and length are deliberately chosen: portrait orientation, short, for a quick glance whenever you have a moment. Google is clearly targeting the viewing habits we’re used to seeing on social media feeds.

The short videos differ from the older Cinematic Video Overviews primarily in length and focus. The Cinematic version is longer, in landscape format, and features more elaborate production with about 20 generations per day. The Short Video Overviews, on the other hand, are geared toward speed and volume. Google apparently wants you to create many of them, one after another, just as you would scroll through a feed.
Nano Banana 2 Lite and Gemini Omni Flash: the models behind them
The short videos aren’t coming alone. At the same time, Google unveiled two new AI models that are primarily intended for developers but are directly integrated into products like NotebookLM.
Behind the name Nano Banana 2 Lite lies the Gemini 3.1 Flash-Lite Image model. Google positions it as the fastest and most affordable image generation and editing model in its portfolio. An image is said to be ready in about four seconds, at a cost of $0.034 per image in 1K resolution, according to Google. Despite the speed, Google promises reliable prompt fidelity, consistent characters across multiple images, and legible text directly within the image. It is precisely this model that generates the images for the Short Video Overviews. A lightweight model fits the concept: A one-minute video must be produced quickly and affordably if you want users to create them in droves.
The second model, Gemini Omni Flash, is entering public preview. It processes text, images, and videos together and uses them to generate new video content, including a native audio track. The price is $0.10 per second of 720p video, which is on par with Veo 3.1 Fast. Both models are accessible via Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform.
Key Technical Specifications at a Glance
| Feature | Nano Banana 2 Lite | Gemini Omni Flash |
|---|---|---|
| Model ID | gemini-3.1-flash-lite-image | gemini-omni-flash-preview |
| Type | Image Generation and Editing | Video generation and editing |
| Speed / Price | Approx. 4 sec. per image, $0.034 per 1K image | $0.10 per second of 720p video |
| Status | Generally available | Public Preview |
| Role at NotebookLM | Generates the images for the short videos | drives parts of the video overviews |
There are still a few limitations with Gemini Omni Flash, which Google openly acknowledges: The model currently generates only 10-second clips, audio references cannot yet be uploaded via the API, and character consistency may break during scene changes. It is therefore not yet intended for production use without careful review of each clip.
Who Can Use the Short Videos
At launch, Google AI Ultra and Pro subscribers will receive the Short Video Overviews, both on mobile and on the web. Google has confirmed that the feature will also be available to users of the free plan, but has not yet provided a specific date. Additionally, the feature will initially be available only in English. For NotebookLM’s other video formats, additional languages typically followed within the weeks after launch, though an official timeline has not yet been announced.
Incidentally, Nano Banana 2 Lite isn’t just coming to NotebookLM. Google is also rolling out the image model in other consumer products, including AI Mode in Google Search, the Gemini app, Google Photos, and Google Ads.
Context: A Smart Move Rather Than a Revolution
NotebookLM has quickly become an essential tool for AI-powered research. What sets it apart is that the platform works exclusively with the sources you upload yourself, distinguishing it from traditional chatbots. The Short Video Overviews are part of a whole series of visual features that Google has recently introduced, ranging from infographics and slide decks to Cinematic videos.
For those who already use NotebookLM, the short videos offer another output format for learning content and summaries. Whether you actually want to scroll through a feed of self-created learning videos is something everyone must decide for themselves. But the trend is clear: Google’s AI tools for knowledge presentation are gradually becoming more visual and mobile.
The integration of NotebookLM notebooks directly into Gemini also demonstrates just how closely Google is now interlinking its AI services. For Pro and Ultra users, NotebookLM also offers the reasoning model from our report on Gemini 3.1 Pro. Meanwhile, competition in the AI learning platform space comes from sources such as Adobe Student Spaces.
