VFX

What is VFX?

The abbreviated VFX stands for Visual effects. Visual effects 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.
