Visual effects (commonly shortened to Visual FX or VFX) include the various processes in which imagery is created and/or manipulated away from context of a live action shot. Visual effects involve the integration of live-action footage and generated imagery to produce environments which look realistic, but will be dangerous, expensive, impractical, or just impossible to capture on film. Visual effects using computer generated imagery has become offered to the independent filmmaker while using introduction of affordable and simple to use animation and compositing software.
Visual effects tend to be integral with a movie’s story and appeal. Although most visual effects jobs are completed during post-production, it usually has to be carefully planned and choreographed in pre-production and production. Visual effects primarily executed in Post-Production, with the aid of multiple tools and technologies for example graphic design, modeling, animation and other alike software, while tricks are made on set, like explosions, car chases etc. A visual effects supervisor is generally involved with the fabrication from an earlier stage to operate closely with production and also the film’s director design, guide and lead the teams necessary to achieve the desired effects.
Visual effects might be divided into at least four categories:
Matte paintings and stills: digital or traditional paintings or photographs which function as background plates for keyed or rotoscoped elements.
Live-action effects: keying actors or models through bluescreening and greenscreening.
