Abstract

Manipulated videos often contain subtle inconsistencies between their visual and audio signals. We propose a video forensics method, based on anomaly detection, that can identify these inconsistencies, and that can be trained solely using real, unlabeled data. We train an autoregressive model to generate sequences of audio-visual features, using feature sets that capture the temporal synchronization between video frames and sound. At test time, we then flag videos that the model assigns low probability. Despite being trained entirely on real videos, our model obtains strong performance on the task of detecting manipulated speech videos.

  • The performance of any deepfake detection method is highly dependent on the quantitative and qualitative aspects of the datasets used for development.

    “The performance of any deepfake detection method is highly dependent on the quantitative and qualitative aspects of the datasets used for development [18, 21, 25, 40, 44, 47, 49, 51, 52, 61, 63, 69, 72, 75].”

    From AV-Deepfake1M: A Large-Scale LLM-Driven Audio-Visual Deepfake Dataset (2024) · cites this paper as [18]

    The paper’s §4.7 ablation study reports no significant performance change when its model is trained on different combinations of LRS2 and LRS3. Section 4.4 likewise says its performance is not tied to a single training set. These findings run counter to the claim that the performance of any deepfake detector is highly dependent on the datasets used for development; the paper does not establish that broader claim about dataset quantity or quality. (LLM, conf=0.86)

    Checked by a reasoning model — may be wrong.

  • Existing surveys do not examine how detection methods withstand adversarial attacks designed to evade detection or postprocessing operations that degrade detection performance.

    “Existing surveys do not examine how detection methods withstand adversarial attacks designed to evade detection [17, 21] or postprocessing operations that degrade detection performance [22-24].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
