Abstract:

Composed Video Retrieval (CoVR) aims to retrieve a target video from a large gallery using a reference video and a textual query specifying visual modifications. However, existing benchmarks consider only visual changes, ignoring videos that differ in audio despite visual similarity. To address this limitation, we introduce Composed retrieval for Video with its Audio (COVA), a new retrieval task that accounts for both visual and auditory variations. To support this, we construct AV-Comp, a benchmark of video pairs with cross-modal changes and textual queries describing the differences, enabling retrieval based on audio as well. We also propose AVT Compositional Fusion (AVT), which integrates video, audio, and text features by selectively aligning the query to the most relevant modality. AVT outperforms traditional unimodal fusion and serves as a strong baseline for COVA.
