Google's NotebookLM is adding a 'Video Overviews' feature. This tool automatically generates videos on requested topics, using data from user-uploaded images, diagrams, quotes, and documents. Currently, Video Overviews are slideshows with narration and only available in English. Google plans to expand language support and the toolset's capabilities, aiming to make it more effective for explaining data, demonstrating processes, and visualizing abstract concepts.
