VFX stands for Visual Effects. It is a process that involves creating or manipulating imagery outside the context of a live-action shot in filmmaking and video production. VFX is used to create scenes and images that do not exist in the real world, such as people, creatures, objects, and worlds that are usually not possible in reality. It deals with combining real-life video and computer-generated imagery (CGI) to create scenes that appear realistic and reasonable but that would be expensive, hazardous, and unfeasible to shoot on film otherwise. VFX is adaptable since it can be used to produce a variety of videos using live footage visuals, edited videos, and computer-generated imagery. The most widely used tool in visual effects is a green screen, which is a background that can be quickly and easily removed from behind the actor after creating the necessary visuals on the background. VFX is distinct from CGI, which is an application of computer graphics (imaging software) that enables you to create images, characters, and video games that look real and may not be possible using other means.
