SPLIT: Training-Free AI-Generated and Partially Edited Video Detection via Spatial Patch-Level Incoherence and Temporal Roughness
arXiv:2607.02886v1 Announce Type: cross Abstract: Deploying AI-generated video detectors in real-world services demands an ultra-low false positive rate (FPR) on real videos to avoid falsely rejecting authentic content, a regime where standard metrics such as AUROC fail to reflect actual operating behavior. We introduce Spatial Patch-Level Incoherence and Temporal Roughness (SPLIT), a training-free detector that operates on patch tokens from a frozen vision encoder to detect both fully generated and partially edited videos. SPLIT computes two complementary signals: Two-step Temporal Roughness
The rapid proliferation and increasing sophistication of AI-generated video necessitate advanced detection methods to maintain trust in digital media and prevent misuse.
This development addresses a critical vulnerability in the information ecosystem by enabling more robust identification of deceptive AI-generated content, crucial for security, media integrity, and preventing disinformation.
The introduction of a training-free, high-accuracy detector significantly improves the ability to distinguish authentic from AI-generated or edited videos, potentially reducing false positives and operational costs for content platforms.

Improved detection capabilities will enhance trust in online video content and provide tools for platforms to combat synthetic media effectively.
This could lead to increased regulatory pressure on AI generative models to include native watermarking or detection-resistant features, shifting responsibility upstream.
The arms race between AI generation and detection will intensify, potentially driving further innovation in both fields and raising ethical considerations around digital authenticity.
