In May 2025, Google's research tool NotebookLM underwent a significant update with plans to launch a new feature called "Sparks," which provides one-to-three minute video summaries. Ten percent of the content will be generated by AI. This innovation will further integrate Gemini2.5 chatbot and Deep Research report functions, offering users an intelligent content creation experience from documents to short videos. AIbase combines the latest social media dynamics to deeply analyze the technical highlights of the "Sparks" video summary and its far-reaching impact on the field of AI content generation.
"Sparks" Video Summary: The AI-driven Revolution in Short Videos
"Sparks" is NotebookLM's upcoming video summary function designed to transform user-uploaded documents, notes, or Deep Research reports into concise one-to-three minute videos. AIbase understands that these videos consist of 10% AI-generated content and 90% based on user input materials, blending text, images, and audio elements into a dynamic narrative similar to a podcast. Users just need to upload their materials, and NotebookLM can automatically generate a clear structure and visually attractive video, suitable for learning, report sharing, or content marketing.
AIbase analyzes that this function relies on the multi-modal capabilities of Gemini2.5Pro to intelligently extract key information from documents, generate scripts, and match visual effects. For example, a research report about "AI Trends in 2025" can be transformed into a short video containing charts, narration, and dynamic transitions, taking only a few minutes to generate. This efficiency makes it an ideal tool for students, researchers, and content creators.
Technical Highlights: Deep Integration of Gemini and Deep Research
The "Sparks" video summary is backed by Google's technological accumulation in NotebookLM and the Gemini ecosystem. AIbase noticed that this function may be driven by the same model supporting NotebookLM Audio Overviews, utilizing the multi-modal generation capabilities of Gemini2.5Pro to seamlessly integrate text, images, and audio. Users can directly generate videos through the Gemini chatbot or convert Deep Research reports with one click, bypassing the complex traditional video editing process.
Deep Research, as Gemini's flagship function, can analyze hundreds of network resources in real time and generate detailed research reports. AIbase tests show that when Deep Research reports are input into NotebookLM, "Sparks" videos can automatically extract key points from the reports, generating visualized content including charts and citations. For example, a report on "Renewable Energy" can be transformed into a three-minute video containing data visualization and AI narration, with a generation speed ten times faster than manual editing.
Multi-scenario Applications: Broad Potential from Education to Business
The flexibility of the "Sparks" video summary makes it applicable to various scenarios:
Educational Field: Students can turn classroom notes or papers into short videos as learning summaries or presentation materials. NotebookLM's Audio Overviews have already been widely popular among students for its podcast-style format, and the "Sparks" video will further enhance the visual learning experience.
Research and Reporting: Researchers can use Deep Research to generate reports, then convert them into videos via "Sparks" for academic conferences or team sharing.
Content Creation: Marketing teams can convert market analysis reports into short videos for social media promotion or client presentations, enhancing brand appeal.
AIbase predicts that the low threshold and high efficiency of "Sparks" videos will promote the popularity of AI content creation, especially in the context of the prevalence of short video platforms (such as TikTok and YouTube Shorts), making its commercial value significant.
Community Response: Innovation Sparks Discussion
Since the news of the "Sparks" video summary was exposed on social media, the developer community and users have shown great enthusiasm. AIbase observes that many users call it a "game-changer" in content creation and look forward to its deep integration with the Gemini chatbot. Some developers have tried similar functions on Hugging Face Spaces, verifying the feasibility of short video generation. AIbase believes that the success of "Sparks" will further consolidate NotebookLM's leading position in the fields of education and research.
However, AIbase also noticed that the 10% AI-generated content may trigger copyright and originality controversies. Google needs to clarify the sources of AI-generated parts to ensure compliance. In addition, the quality and consistency of video generation still need to be tested by users after the official release.
Industry Impact: The Next Wave of AI Content Generation
The launch of the "Sparks" video summary marks the comprehensive evolution of AI content generation from text and audio to video. AIbase analyzes that compared to OpenAI's Sora or Runway's video generation tools, "Sparks" focuses more on structured content, providing an end-to-end solution from research to presentation by integrating Deep Research and the Gemini ecosystem. This vertical integration gives Google an edge in the AI-driven content creation market.
AIbase also observes that "Sparks" may provide inspiration for domestic AI tools (such as MiniMax Speech-02 or Qwen3), encouraging Chinese developers to explore the combination of video and multimodal AI. In the future, as NotebookLM supports more languages (such as the recent addition of 50 languages for Audio Overviews), its global influence will expand further.
Another Masterpiece of Google's AI Ecosystem
As a professional media in the AI field, AIbase highly appreciates the innovation of NotebookLM's "Sparks" video summary. Its combined capabilities of Gemini2.5 and Deep Research offer users a smooth experience from complex research to intuitive videos, truly realizing the vision of "AI Empowering Content Creation." Of particular note is that "Sparks" may drive the application of AI in China's education and content creation sectors, accelerating localized innovation.
