[KDD'2026] "VideoRAG: Chat with Your Videos"

A new open-source framework, VideoRAG, transforms how users interact with video content, enabling AI-powered conversations with clips spanning hundreds of hours. This technology, detailed in a forthcoming KDD 2026 paper, allows users to ask complex questions in natural language and receive accurate answers, pulling insights from both visual and audio data, according to GitHub. It effectively acts as a personal AI assistant, capable of "watching" and understanding vast video libraries to retrieve specific information.

For anyone who has ever painstakingly scrubbed through a two-hour lecture, a long documentary, or a sprawling security footage archive, VideoRAG offers a powerful solution. The framework's accompanying desktop application, Vimo, is designed for both casual users and power analysts, supporting various video formats like MP4, MKV, and AVI across macOS, Windows, and Linux. This tool fundamentally shifts video consumption from passive viewing to active, conversational query.

How Does VideoRAG Understand Videos?

Imagine having a hyper-efficient research assistant who can digest entire libraries of video content and recall any specific detail you ask for, no matter how obscure. That's precisely what VideoRAG brings to the table. It doesn't just skim; it builds a comprehensive understanding of the video's narrative, visual elements, and spoken dialogue. This deep comprehension makes it possible to query vast amounts of video data instantly.

The core of VideoRAG is its novel dual-channel architecture. It employs graph-driven knowledge indexing, constructing multi-modal knowledge graphs to give structure to video understanding. Simultaneously, it uses hierarchical context encoding to preserve spatiotemporal visual patterns across incredibly long sequences. This approach allows the system to distill hundreds of hours of video into concise, searchable knowledge representations.

VideoRAG also features adaptive retrieval mechanisms optimized for video content and cross-video understanding, enabling semantic relationship modeling across multiple videos. This capability is crucial for comparative analysis or tracking themes across a series of clips. Impressively, this intricate processing can run efficiently on a single Nvidia RTX 3090 GPU, handling hundreds of hours with its 24GB of memory.

What Impact Will This Have on Video Analysis?

This framework changes the game for video content interaction. Researchers can leverage the underlying VideoRAG algorithm and a new benchmark dataset called LongerVideos, which comprises over 134 hours of content across lectures, documentaries, and entertainment. This allows for rigorous evaluation and further development in extreme long-context video understanding. The system achieves a 60.2% accuracy on the Video-MME long video track, significantly outperforming existing backbone models.

For everyday users and professionals, Vimo simplifies complex video analysis. Instead of manually reviewing footage, users can pose questions in natural language and get immediate, contextually rich answers. This is a massive leap from keyword searches, which often miss nuances or rely solely on transcriptions. The ability to handle "extreme long videos" means everything from historical archives to multi-day conference recordings becomes searchable and understandable.

The open-source nature of VideoRAG invites contributions from the community, whether through bug reports, algorithmic improvements, or UI/UX enhancements. This collaborative model accelerates the development of intelligent video interaction, setting a new standard for how we derive insights from the ever-growing volume of video content. This level of granular, conversational access ensures no detail is lost, even in the longest visual narratives.
