<<Publication Purpose and Content Introduction>>

This book covers the implementation methods for technology that enables searching based on the content of videos themselves using AI. Addressing the current challenge where video search relies on metadata like titles and descriptions and cannot directly search the content of videos, this book clearly presents the mechanism of video understanding through multimodal analysis of video, audio, and text, and how it differs from conventional search methods. In building a basic pipeline for scene search from video, it introduces the entire flow—from loading video and acquiring metadata, to detecting scene boundaries, extracting text through speech recognition and OCR, generating image captions, and building a search index via multimodal embedding—along with actual working code. It also details the concepts of embedding vectors, similarity calculation, and the use of vector databases for efficient search. Furthermore, by explaining the basic mechanism of RAG and its application to video search, it clarifies why combining search and generation can provide more accurate search results. The book is structured so readers can try the entire process—from video upload to scene analysis, vector registration, and natural language search—using a demo application. This is a must-read for anyone interested in video analysis and multimodal AI.
