In our submission for the Hackathon for Good, we created a working POC which is a website where people can easily paste youtube links or upload videos to have them be checked for manipulated sections. The deepfake detection is done using the model from FaceForensics++, which has around 80% accuracy on a combination of compressed videos, but achieves around 99% accuracy on a single type of compression.
The POC also allows for easy checking whether a video has been seen before with a database of video hashes which can be searched.
For usage, one needs to download the model weights from the FaceForensics repository and put them in classification/weights. Then call flask run in the top level directory.
