Visual Effects :
Visual Effects are often integral to a movie's story and appeal. Although most visual effects work is completed during post-production stage, it usually must be carefully planned and choreographed in pre-production and production. Visual effects primarily executed in Post-Production, with the use of multiple tools and technologies such as graphic design, modeling, animation and similar software, while special effects are made on set, such as explosions, car chases and so on. A visual effects supervisor is usually involved with the production from an early stage to work closely with production and the film's director design, guide and lead the teams required to achieve the desired effects.
