The Google NotebookLM tool has received a major upgrade. Its AI-driven video overview function adds a "Cinematic Video Overviews" feature to further optimize the video experience.
This feature goes beyond the traditional narrative slideshow model and leverages generative AI models such as Google’s Gemini 3, Nano Banana Pro and Veo 3 to create smooth animations and detailed visuals around user-specified topics.
Gemini AI acts as a "creative director", automatically determining the best narrative structure, visual style and format, and iteratively optimizing to ensure consistency, thereby efficiently telling the story of the source material uploaded by the user.
This feature is currently limited to English and is available to users aged 18 and above. It is open to Google AI Ultra subscribers on the web and mobile terminals. Google has not yet announced a timetable for expansion to other paid plans or free users.
Looking back at history, the video overview function was launched last year. Based on the audio overview extension, it can generate animated videos with AI moderators. The screen displays images, charts and quotes. Users can add prompts to specify focus and visual style.
However, excessive use of AI has also caused controversy. National Public Radio (NPR) "Morning Edition" host David Greene once sued Google, claiming that its NotebookLM's AI male voice was similar to his, causing many people to misidentify his authorized voice.
