Definition & Meaning of "visual effects"

What are "visual effects"?

Visual effects (VFX) are techniques used in film, television, and other media to create or enhance imagery that cannot be captured during live-action filming. These effects are achieved through various methods, including computer-generated imagery (CGI), digital compositing, and practical effects. Visual effects can be used to create fantastical worlds, simulate complex actions, add elements that are not present on set, or enhance scenes to achieve a specific look or mood. They play a crucial role in bringing imaginative ideas to life and providing viewers with a more engaging and visually compelling experience.
