The Innovation
A team of researchers from KAIST and DeepAuto.ai has developed VideoRAG, a framework that takes Retrieval-Augmented Generation (RAG) in a new direction by tapping into the rich potential of video content as a knowledge source. Unlike traditional RAG systems that rely solely on text, VideoRAG dynamically retrieves relevant videos and processes both their visual and textual elements. This comprehensive approach is made possible through the sophisticated use of Large Video Language Models (LVLMs).
Measurable Impact
The results speak for themselves. When compared to baseline systems, VideoRAG demonstrates significant improvements across all standard metrics. The framework achieved a ROUGE-L score of 0.254 (up from 0.141), BLEU-4 of 0.054 (increased from 0.014), BERTScore of 0.881 (improved from 0.834), and G-Eval of 2.161 (elevated from 1.579).
Technical Architecture
At its core, VideoRAG's implementation combines three powerful components. It uses InternVideo for precise retrieval tasks, leveraging its strong semantic alignment capabilities. The video-augmented answer generation is handled by LLaVA-Video-7B, while Whisper efficiently extracts textual content from videos that lack subtitles.
Real-World Applications
The practical applications of VideoRAG shine in scenarios requiring detailed instruction or demonstration. The system excels at delivering instructional content, explaining complex processes, and providing comprehensive step-by-step guidance. Its ability to understand and process visual demonstrations makes it particularly effective in educational and training contexts.

Research Significance
This research represents a significant step forward in addressing the limitations of current RAG systems. By moving beyond text-only knowledge sources and incorporating temporal dynamics and spatial relationships, VideoRAG offers a more complete and nuanced understanding of content.
Research Team
The advancement comes from Soyeong Jeong, Kangsan Kim, and Jinheon Baek from KAIST, along with Sung Ju Hwang, who is affiliated with both KAIST and DeepAuto.ai.
Note: As of January 24, 2025, while the research findings are publicly available, the official code repository has not been released. Interested developers and researchers should monitor the authors' GitHub profiles and paper updates for future code releases.
