Visual effects (sometimes abbreviated as VFX) is the process by which imagery is created or manipulated outside the context of a live-action shot in filmmaking and video production. The integration of live-action footage and other live-action footage or computer-generated imagery (CGI) elements to create realistic imagery is called VFX. VFX involves the integration of live-action footage (which may include in-camera special effects) and generated imagery (digital or optics, animals or creatures) which look realistic, but would be dangerous, expensive, impractical, time-consuming or impossible to capture on film. Visual effects using CGI have more recently become accessible to the independent filmmaker with the introduction of affordable and relatively easy-to-use animation and compositing software.
