Researchers have developed MMTM, a novel pipeline for discovering topics in long-form videos by combining speech recognition, audio and visual embeddings, and BERTopic clustering. This tri-modal approach significantly enhances topic quality, reducing noise and improving temporal stability, as demonstrated by substantial improvements in metrics like cluster validity and lexical coherence. The team has released the pipeline code and a large, human-validated multimodal video topic corpus to facilitate further research. AI
