As part of the study, scientists have identified the weaknesses of such videos. They noticed that the errors that issued the fake video were always repeated. Thus, one can suspect the deepfake of the first generation video due to the different shades of the left and right eyes. You can find out that the video is fake if the portrait has different distances from the center of the eyes to the edge of the iris. In addition, the deepfake video also gives out the absence of the correct rounded contours of the limb.

Among other things, in such videos, you can often see poorly traced teeth. At the moment, the most modern way to recognize deepfake is to compare the light that is reflected in the corneas of the eye.
