Google appears to be advancing its video overviews feature within NotebookLM, just ahead of its I/O event. A post from the Google Labs account referenced last year’s I/O debut of audio overviews, short spoken summaries generated from user content. This year, attention seems to shift toward video, with evidence pointing to a more elaborate storytelling format combining both visuals and voice.
We are less than ONE WEEK out from this year's #GoogleIO. In last year's keynote, we unveiled @NotebookLM’s Audio Overviews. This year we have cooked up even more fun stuff in the Lab. 😉😉😉

Any guesses for what kinds of experiments we've been working on?
The updated interface for video overviews now includes a length selector—users can choose between “default” and “longer” versions—and introduces a prompt field that allows for deeper customization. This prompt guides users to define the focus topic, preferred visuals, or elements to emphasize. According to the updated feature description, the final output resembles a podcast-like video, narrated by two virtual hosts discussing the selected topic while showing visuals that match the narrative. It is also yet unclear if Video Overviews will be powered by recently spotted Veo 3, which would make this feature even more exciting.
Things to try
• Target a specific use case (“present this to a book club“, “help me review for a quiz“)
• Focus on a specific source (“show the photos from the album“, “focus on the biology paper”)
• Describe the show structure (“start by talking about the mission”, “end with next steps“)
This could be especially useful for content creators, educators, and media publishers, particularly for those producing summaries or commentary on technical topics. NotebookLM’s dual support for audio and video formats potentially allows for fully AI-generated multimedia briefings from textual inputs alone.
The feature is not yet publicly released, but its presence in the interface and subtle nudges via official posts suggest it may be showcased or launched during the upcoming I/O conference.
