A fake video, also known as a deepfake, is a manipulated or fabricated video that presents false information or portrays events that never actually occurred. These videos are created using advanced technology, such as artificial intelligence and machine learning, to alter or replace the original content with deceptive elements. The purpose of a fake video can range from spreading misinformation to creating false evidence or simply for entertainment. With the rise of social media and the ease of sharing videos, the danger of fake videos has increased, making it crucial to critically evaluate the authenticity of any video before believing or sharing it.
