What does Frame-AUC of FF++ is 0.0000 Video-AUC of FF++ is 0.0000 represents

[AB00k]

I used a random video and created it's ldm.json and then run the test and finally received following response (I actually had to put another video in orignal folder to make it work):

Loaded pretrained weights for efficientnet-b3 Load deepfake dataset from ./test_images.. /usr/local/lib/python3.10/dist-packages/torch/utils/data/dataloader.py:558: UserWarning: This DataLoader will create 4 worker processes in total. Our suggested max number of worker in current system is 2, which is smaller than what this DataLoader is going to create. Please be aware that excessive worker creation might get DataLoader running slow or even freeze, lower the worker number to avoid potential slowness/freeze if necessary. warnings.warn(_create_warning_msg( [ WARN:[email protected]] global loadsave.cpp:241 findDecoder imread_('./test_images/original_sequences/youtube/raw/frames/video/frame_0.png'): can't open/read file: check file path/integrity Frame-AUC of FF++ is 0.0000 Video-AUC of FF++ is 0.0000

I'm unable to understand what does Frame-AUC and Video-AUC represents, I would really appreciate any kind response.
