Answer:
Visual effects (abbreviated VFX) is the process by which imagery is created or manipulated outside the context of a live action shot in filmmaking. The integration of live action footage and CG elements to create realistic imagery is called VFX.
VFX involves the integration of live action footage (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 computer-generated imagery (CGI) have recently become accessible to the independent filmmaker with the introduction of affordable and relatively easy-to-use animation and compositing software.
