Abstract

The detection and localization of highly realistic deepfake audio-visual content are challenging even for the most advanced state-of-the-art methods. While most of the research efforts in this domain are focused on detecting high-quality deepfake images and videos, only a few works address the problem of the localization of small segments of audio-visual manipulations embedded in real videos. In this research, we emulate the process of such content generation and propose the AV-Deepfake1M dataset. The dataset contains content-driven (i) video manipulations, (ii) audio manipulations, and (iii) audio-visual manipulations for more than 2K subjects resulting in a total of more than 1M videos. The paper provides a thorough description of the proposed data generation pipeline accompanied by a rigorous analysis of the quality of the generated data. The comprehensive benchmark of the proposed dataset utilizing state-of-the-art deepfake detection and localization methods indicates a significant drop in performance compared to previous datasets. The proposed dataset will play a vital role in building the next-generation deepfake localization methods.

Metadata Structure

The metadata is a json file for each subset (train, val), which is a list of dictionaries. The fields in the dictionary are as follows.

• file: the path to the video file.
• original: if the current video is fake, the path to the original video; otherwise, the original path in VoxCeleb2.
• split: the name of the current subset.
• modify_type: the type of modifications in different modalities, which can be ["real", "visual_modified", "audio_modified", "both_modified"]. We evaluate the deepfake detection performance based on this field.
• audio_model: the audio generation model used for generating this video.
• fake_segments: the timestamps of the fake segments. We evaluate the temporal localization performance based on this field.
• audio_fake_segments: the timestamps of the fake segments in audio modality.
• visual_fake_segments: the timestamps of the fake segments in visual modality.
• video_frames: the number of frames in the video.
• audio_frames: the number of frames in the audio.

SDK

We provide a Python library avdeepfake1m to load the dataset and evaluation.

Installation

pip install avdeepfake1m

Usage

Prepare the dataset as follows.

|- train_metadata.json
|- train_metadata
|  |- ...
|- train
|  |- ...
|- val_metadata.json
|- val_metadata
|  |- ...
|- val
|  |- ...
|- test_files.txt
|- test

Load the dataset.

from avdeepfake1m.loader import AVDeepfake1mDataModule

# access to Lightning DataModule
dm = AVDeepfake1mDataModule("/path/to/dataset")

Evaluate the predictions. Firstly prepare the predictions as described in the details. Then run the following code.

from avdeepfake1m.evaluation import ap_ar_1d, auc
print(ap_ar_1d("<PREDICTION_JSON>", "<METADATA_JSON>", "file", "fake_segments", 1, [0.5, 0.75, 0.9, 0.95], [50, 30, 20, 10, 5], [0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95]))
print(auc("<PREDICTION_TXT>", "<METADATA_JSON>", "file", "fake_segments"))
