Your One-Stop Solution for AI-Generated Video Detection

Recent advances in generative modeling can create remarkably realistic synthetic videos, making it increasingly difficult for humans to distinguish them from real ones and necessitating reliable detection methods. However, two key limitations hinder the development of this field. $\mathbf{\text{From}}\mathbf{\text{the}}\mathbf{\text{dataset}}\mathbf{\text{perspective}}$, existing datasets are often limited in scale and constructed using outdated or narrowly scoped generative models, making it difficult to capture the diversity and rapid evolution of modern generative techniques. Moreover, the dataset construction process frequently prioritizes quantity over quality, neglecting essential aspects such as semantic diversity, scenario coverage, and technological representativeness. $\mathbf{\text{From}}\mathbf{\text{the}}\mathbf{\text{benchmark}}\mathbf{\text{perspective}}$, current benchmarks largely remain at the stage of dataset creation, leaving many fundamental issues and in-depth analysis yet to be systematically explored. Addressing this gap, we propose AIGVDBench, a benchmark designed to be comprehensive and representative, covering $\mathbf{\text{31}}$ state-of-the-art generation models and over $\mathbf{\text{440,000}}$ videos. By executing more than $\mathbf{\text{1,500}}$ evaluations on $\mathbf{\text{33}}$ existing detectors belonging to four distinct categories. This work presents $\mathbf{\text{8}}\mathbf{\text{in-depth}}\mathbf{\text{analyses}}$ from multiple perspectives and identifies $\mathbf{\text{4}}\mathbf{\text{novel}}\mathbf{\text{findings}}$ that offer valuable insights for future research. We hope this work provides a solid foundation for advancing the field of AI-generated video detection. Our benchmark is open-sourced at https://github.com/LongMa-2025/AIGVDBench.
