What is VFX?
Visual Effects (abbreviated VFX ) is the process by which imagery is created or manipulated outside the context of a live action shot in filmmaking. Visual effects involved in the integration of live-action footage ( special effects ) and generated imagery (digital effects) to create environments 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 easy-to-use animation and compositing software
