TL;DR
利用H.264视频编解码器中的运动矢量和信息掩码来检测DeepFakes中的时间不一致性，该方法在有效性和计算成本方面表现出色，可用于视频通话和流媒体的实时时间感知DeepFake检测方法。
Abstract
video deepfakes
are fake media created with
deep learning
(DL) that manipulate a person's expression or identity. Most current DeepFake detection methods analyze each frame independently, ignoring inconsistencies
