For those interested in creating deepfakes for legitimate purposes, such as filmmaking, education, or research:

At the heart of deepfake creation lies a process known as deep learning. This AI method involves training neural networks on extensive datasets of images or videos. Over time, these networks learn to identify and replicate the patterns and nuances of the input data, enabling the generation of new, synthetic media. The result can range from simple image swaps to complex videos where the subject's expressions, voice, and movements are convincingly altered.
