Search first, inspect visually when needed: A multi-agent architecture for semantic video archival retrieval

Tech Papers 2026: This paper introduces Smart Chat, a multi-agent video question-answering system that searches indexed video moments, localizes candidate evidence, and inspects a short clip only when visual verification is needed.

Abstract 

Broadcast, over-the-top (OTT), and free ad-supported streaming TV (FAST) archives contain visual evidence that is difficult to search and reason over using metadata, filenames, and transcripts alone.  

It builds on a deployed indexed-moment foundation, extending it from retrieval to timestamp-grounded question answering.
