extractfaces.py
   Face extraction from video.
   The code works for DFDC dataset. You can test it using the sample data provided.

deepfake_cvit_gpu_ep_50.pth - Full model weight.
deepfake_cvit_gpu_inference_ep_50.pth - For detection.

python cvit_prediction.py
    Predicts whether a video is Deepfake or not.
    Prediction value <0.5 - REAL
    Prediction value >=5 - FAKE

To train the model on your own you can use the following parameters:
  e: epoch
  s: session - (g) - GPU or (t) - TPU
  w: weight decay default= 0.0000001
  l: learning rate default=0.001
  d: path file
  b: batch size, defualt=32

python cvit_train.py -e 10 -s 'g' -l 0.0001 -w 0.0000001 -d sample_train_data/
