📝 Introduction

🌟 CaReBench is a fine-grained benchmark comprising 1,000 high-quality videos with detailed human-annotated captions, including manually separated spatial and temporal descriptions for independent spatiotemporal bias evaluation.

📊 ReBias and CapST Metrics are designed specifically for retrieval and captioning tasks, providing a comprehensive evaluation framework for spatiotemporal understanding in video-language models.

⚡ CaRe: A Unified Baseline for fine-grained video retrieval and captioning, achieving competitive performance through two-stage Supervised Fine-Tuning (SFT). CaRe excels in both generating detailed video descriptions and extracting robust video features.

🚀 State-of-the-art performance on both detailed video captioning and fine-grained video retrieval. CaRe outperforms CLIP-based retrieval models and popular MLLMs in captioning tasks.
