1University of Chicago, 2Virtue AI, 3University of Illinois, Urbana-Champaign
Overview: With the wide adoption of generative AI and rapid growth of high-quality video generation, video guardrails have become more crucial than ever to ensure safety and security across platforms. We introduce SafeWatch, an efficient MLLM-based video guardrail model designed to follow customized safety policies and provide multi-label video guardrail outputs with content-specific explanations. Specifically, SafeWatch incorporates two powerful modules to tackle the high inference latency and policy bias under lengthy safety guidelines input, ensuring a focused, policy-compliant guardrail with significantly reduced computational overhead. In addition, we introduce SafeWatch-Bench, a large-scale high-quality video guardrail dataset covering over 30 comprehensive unsafe video scenarios for training and benchmark our model.

(1) Strong policy-following to provide multi-label guardrail flags with precise explanations.
(2) Novel Architecture for achieving low infer- ence latency and mitigating policy input bias.
(3) Advanced Training for accurate guardrail and grounded explanation for both real-world and generative videos.
(1) Large & High-quality: Contain 2M+ videos annotated in high quality by multi-agent LLMs;
(2) Comprehensive Coverage: Cover 6 policy categories and over 30 safety-related scenarios;
(3) Real-world and GenAI: Cover challenging videos produced in both real-world settings and various generative models.
(1) SafeWatch-Bench: On both real-world and generative video subset, SafeWatch outperforms SOTAs by 29.2% and 27.2% on average;
(2) Existing Guardrail Tasks: On 5 existing benchmarks, SafeWatch achieves 87.1% accuracy;
(3) Unseen Tasks: On 8 new video categories or prompting tasks, SafeWatch has high accuracy.

The dataset features two distinct subsets:
β’ Real-World Subset: Curated from diverse online sources including social media platforms and existing datasets. To ensure comprehensive coverage and challenge, we: (1) Collect videos from diverse sources (e.g., short videos, livestreams, and films), covering a range of content types, lengths, and scenarios to maximize diversity; (2) Maintain balanced demographic representation by collecting from diverse user groups; (3) Include challenging benign examples (borderline-safe videos) to maintain low false positive rate and improve model robustness.
β’ Generative Subset: Features high-quality unsafe videos generated by SOTA models: (1) Text-to-Video: generated using curated unsafe prompts from SafeWatch-Bench-Real captions and existing unsafe prompt datasets (e.g. I2P); (2) Image-to-Video: generated from SafeWatch-Bench-Real screenshots and existing unsafe image datasets; (3) Significantly higher quality and better alignment with sophisticated unsafe scenarios compared to existing datasets.
Annotation: Each video is annotated with multi-label guardrail flags and in-depth explanations through our multi-agent propose-discuss consensus pipeline, ensuring comprehensive coverage while maintaining exceptional annotation quality.
