Visual Effects (VFX) refers to the process of creating or manipulating imagery outside the context of live-action shooting — used to enhance, add, or completely create elements that would be impossible, dangerous, or too expensive to film in real life. VFX is widely used in films, TV shows, advertisements, music videos, and increasingly in YouTube content and social media reels. Common examples include adding explosions, replacing backgrounds, creating fantasy creatures, or simulating weather effects like rain and snow. Understanding the difference between VFX and general video editing is important — editing focuses on arranging footage, while VFX focuses on altering or adding to what was actually filmed.
