❗️❗️❗️ News:
NEW DATASET: We are excited to introduce our brand-new deepfake dataset called DF40, comprising 40 distinct deepfake techniques, even the just released SoTAs. DF40 is designed for seamless integration into the workflow of DeepfakeBench, allowing you to train or test just as you would with other datasets like Celeb-DF and FF++. Please refer to DF40 dataset for details.
** OUR LATEST WORK **: Our latest research paper has been released at ArXiv. We propose a highly generalizable and efficient detection model that can be used to detect both face deepfake images and synthetic images (not limited to face). We will soon release all the codes implemented by the DeepfakeBench codebase.
We implement two recent SoTA video detectors: AltFreezing (CVPR 2023) and TALL (ICCV 2023) on our benchmark. We release their pre-trained weights on FF++ via Google Drive AltFreezing and TALL. You can also use our codebase to retrain this model from scratch. The training and evaluation processes will be the same as those of other detectors on DeepfakeBench.
The pre-trained weights of 3D R50 for training I3D, FTCN, and AltFreezing are here

Other datasets are similar to the above structure
If you choose to store your datasets in a different folder, you may specified the rgb_dir or lmdb_dir in training\test_config.yaml and training\train_config.yaml.
The downloaded json configurations should be arranged as:
preprocessing
├── dataset_json
| ├── FaceForensics++.json
You may also store your configurations in a different folder by specifying the dataset_json_folder in training\test_config.yaml and training\train_config.yaml.
❗️Note: If you want to directly utilize the data, including frames, landmarks, masks, and more, that I have provided above, you can skip the pre-processing step. However, you still need to run the rearrangement script to generate the JSON file for each dataset for the unified data loading in the training and testing process.
DeepfakeBench follows a sequential workflow for face detection, alignment, and cropping. The processed data, including face images, landmarks, and masks, are saved in separate folders for further analysis.
To start preprocessing your dataset, please follow these steps:
-
Download the shape_predictor_81_face_landmarks.dat file. Then, copy the downloaded shape_predictor_81_face_landmarks.dat file into the
./preprocessing/dlib_tools folder. This file is necessary for Dlib's face detection functionality. -
Open the
./preprocessing/config.yamland locate the linedefault: DATASET_YOU_SPECIFY. ReplaceDATASET_YOU_SPECIFYwith the name of the dataset you want to preprocess, such asFaceForensics++. -
Specify the
dataset_root_pathin the config.yaml file. Search for the line that mentions dataset_root_path. By default, it looks like this:dataset_root_path: ./datasets. Replace./datasetswith the actual path to the folder where your dataset is arranged.
Once you have completed these steps, you can proceed with running the following line to do the preprocessing:
cd preprocessing
python preprocess.py
You may skip the preprocessing step by downloading the provided data.
To simplify the handling of different datasets, we propose a unified and convenient way to load them. The function eliminates the need to write separate input/output (I/O) code for each dataset, reducing duplication of effort and easing data management.
After the preprocessing above, you will obtain the processed data (i.e., frames, landmarks, and masks) for each dataset you specify. Similarly, you need to set the parameters in ./preprocessing/config.yaml for each dataset. After that, run the following line:
cd preprocessing
python rearrange.py
After running the above line, you will obtain the JSON files for each dataset in the ./preprocessing/dataset_json folder. The rearranged structure organizes the data in a hierarchical manner, grouping videos based on their labels and data splits (i.e., train, test, validation). Each video is represented as a dictionary entry containing relevant metadata, including file paths, labels, compression levels (if applicable), etc.
To run the training code, you should first download the pretrained weights for the corresponding backbones (These pre-trained weights are from ImageNet). You can download them from Link. After downloading, you need to put all the weights files into the folder ./training/pretrained.
Then, you should go to the ./training/config/detector/ folder and then Choose the detector to be trained. For instance, you can adjust the parameters in xception.yaml to specify the parameters, e.g., training and testing datasets, epoch, frame_num, etc.
After setting the parameters, you can run with the following to train the Xception detector:
python training/train.py \
--detector_path ./training/config/detector/xception.yaml
You can also adjust the training and testing datasets using the command line, for example:
python training/train.py \
--detector_path ./training/config/detector/xception.yaml \
--train_dataset "FaceForensics++" \
--test_dataset "Celeb-DF-v1" "Celeb-DF-v2"
By default, the checkpoints and features will be saved during the training process. If you do not want to save them, run with the following:
python training/train.py \
--detector_path ./training/config/detector/xception.yaml \
--train_dataset "FaceForensics++" \
--test_dataset "Celeb-DF-v1" "Celeb-DF-v2" \
--no-save_ckpt \
--no-save_feat
For multi-gpus training (DDP), please refer to train.sh file for details.
To train other detectors using the code mentioned above, you can specify the config file accordingly. However, for the Face X-ray detector, an additional step is required before training. To save training time, a pickle file is generated to store the Top-N nearest images for each given image. To generate this file, you should run the generate_xray_nearest.py file. Once the pickle file is created, you can train the Face X-ray detector using the same way above. If you want to check/use the files I have already generated, please refer to the link.
If you only want to evaluate the detectors to produce the results of the cross-dataset evaluation, you can use the the test.py code for evaluation. Here is an example:
python3 training/test.py \
--detector_path ./training/config/detector/xception.yaml \
--test_dataset "Celeb-DF-v1" "Celeb-DF-v2" "DFDCP" \
--weights_path ./training/weights/xception_best.pth
Note that we have provided the pre-trained weights for each detector (you can download them from the link). Make sure to put these weights in the ./training/weights folder.
❗️❗️❗️ DeepfakeBench-v2 Updates:
The below results are cited from our paper. We have conducted more comprehensive evaluations using the DeepfakeBench-v2, with more datasets used and more detectors implemented. We will update the below table soon.
In our Benchmark, we apply TensorBoard to monitor the progress of training models. It provides a visual representation of the training process, allowing users to examine training results conveniently.
To demonstrate the effectiveness of different detectors, we present partial results from both within-domain and cross-domain evaluations. The evaluation metric used is the frame-level Area Under the Curve (AUC). In this particular scenario, we train the detectors on the FF++ (c23) dataset and assess their performance on other datasets.
For a comprehensive overview of the results, we strongly recommend referring to our paper. These resources provide a detailed analysis of the training outcomes and offer a deeper understanding of the methodology and findings.
