Researchers have developed new frameworks for zero-shot composed video retrieval, a task that involves finding a target video based on a reference video and a textual modification instruction. These methods, presented at the CVPR 2026 VidLLMs workshop, utilize frozen foundation models to reason about the implied changes and re-rank potential candidates. One approach, R3-CoVR, achieved high accuracy by using a multimodal LLM to generate post-edit descriptions and a constraint-aware re-ranker, while another, R^3, focuses on reasoning-guided recalling and re-ranking.
