VFX, or visual effects, refers to the creation and integration of computer-generated (CGI) images, animations, and effects into live-action footage or other media to create an illusion of reality or support visual narratives. VFX are often used in film, television, commercials, music videos, and computer games to create scenes and elements that would be impossible to achieve in the real world due to budget restrictions, security risks, or physical limits. VFX serve a range of purposes, including:Realism and Immersion: By using VFX, filmmakers and game developers can create realistic environments, characters, and events that immerse audiences in the world of narrative .Creativity and Artistic Expression: VFX enable artists and designers to realize their creative visions without the limitations of reality and create impressive visual effects and styles.Cost and time savings: In many cases, VFX can be a cheaper and faster alternative to creating sets, props, and special effects in the real world.
