MVAD：A Comprehensive Multimodal Video-Audio Dataset for AIGC Detection

MVAD is the first general-purpose dataset specifically designed for detecting AI-generated multimodal video-audio content. https://www.arxiv.org/abs/2512.00336

:file_folder: Dataset Overview

Statistics of multimodal video-audio data in the MVAD dataset:

Reflecting the diversity of multimodal video-audio content in real-world scenarios, MVAD spans two visual domains (realistic and anime-style) and covers four primary categories: humans, animals, objects, and scenes. The dataset incorporates three video-audio forgery types and four modality combinations (fake-fake, fake-real, real-fake, real-real). As shown in Table, MVAD contains 205,758 multimodal video-audio samples generated using over 20 distinct methods, including 104,578 forged and 101,000 authentic samples. Following conventional dataset design principles , MVAD maintains a 1:1 ratio between forged and authentic samples. The distribution across modality combinations is as follows: fake-fake (62,178 samples), real-fake (31,880), fake-real (10,700), and real-real (101,000).
