DF26: We Cannot Tell Fake From Real Anymore
🤖 AI Summary
本文通过引入DF26基准来解决AI生成视频的检测问题，该基准包含271个真实视频和2420个由现代模型生成的合成视频，揭示了当前检测方法的局限性。
📝 Abstract
We introduce DF26, a novel benchmark for detecting AI-generated videos containing fully synthetic clips produced by recent text-to-video and image-to-video models. The videos capture single-person public-speaking scenarios, spanning direct-to-camera recordings, official statements, and studio interviews - 271 real and 2,420 synthetic videos generated by seven modern video models. The study on DF26 shows that human performance in detecting AI-generated videos, as well as state-of-the-art deepfake detectors, is close to random chance. Our results highlight the limitations of current evaluation protocols and motivate the need for benchmarks that explicitly measure robustness to modern generative model distribution shifts.
