The creation of visual effects typically involves four stages: pre-production, production, post-production and distribution. The process begins with the preparation of the necessary elements (visual effects scenes/sequences) for the visual effects producer or visual effects supervisor to use in creating the final product. This preparation may include organizing and editing of footage, the creation of storyboards, 3D models, matte paintings and on-set data for set visualization. The actual production consists of filming or obtaining existing footage, editing the material into the desired format, and adding any necessary visual effects. The tv storyboard consists of numerous squares filled with drawings that depict wide, medium and tight shots, along with notes or directions about what is happening.
Visual effects are then used to complete film or video in post-production by adding computer graphics, sound effects, music, digitally compositing various elements together to create the finished product. It may also involve correcting any technical issues in existing footage before adding visual effects so that everything will appear seamless and professional looking. Finally, when completed, a visual effect is distributed either by being released directly to movie theaters or television broadcast or by being incorporated onto a recording medium for later playback.
Visual effects (often abbreviated as VFX) is the process of using computers to create or contribute to images in art, printed media, video games and movies. Visual effects involve the integration of live-action footage and generated imagery (or CGI) to create environments which look realistic, like the sky of a planet or the distant view from a spaceship. Visual effects involve not just the placement of 2D images into a movie but also the integrated 3D elements and computer generated elements. It is a subcategory of visual effects and animation, which includes digital compositing, animation and motion graphics, along with other forms of image manipulation.

In the field of filmmaking, visual effects (abbreviated VFX) are the techniques used to create and integrate an object or an image into a natural setting. Visual effects involve the integration of live-action footage and generated imagery (computer-generated imagery or CGI). Visual effects involve the integration of live-action footage and generating imagery. The history of visual effects is closely tied to the history of computer graphics. It started with simple opticals such as matte shot and multiple exposure, moved on to blue screen and other compositing techniques in the 1960s, and it transformed dramatically again in the mid-1990s with the advent of digital effects.
The digital revolution introduced many new and powerful tools for visual effects: fully digital cinematography and camera movements; various approaches to computer-generated imagery (CGI); and numerous software applications for digital image compositing. The combination of digital cameras and CGI has become known as “HDRI”, which stands for high dynamic range imaging.[1] There were several different approaches to this kind of photography: The traditional method involved using a blue backing (either painted on a wall or a separate piece of material) while shooting actors against a bluescreen made from Chroma key (blue or green background).
Visual effects (abbreviated VFX) is the process by which imagery is created and/or manipulated outside the context of a live action shot. The creation of visual effects involves the use of computers to generate or manipulate an image, animation, or film.
Visual effects include:
Matte paintings: images that use a combination of photographs and coloring to create the appearance of a lost backdrop; using bluescreen and/or greenscreen techniques.
Photographic effects: digital manipulation of photographs. Computer generated imagery (CGI): generation of 3D models and their integration into pre-filmed scenes. Motion capture animation. Computer generated imagery is most prevalent in movies today, as it allows directors to create extremely complex images at minimal cost.
Many movies today rely heavily on CGI for special effects, especially those that are science fiction or fantasy genre films. CGI has also become more popular in television shows as well as commercials due to its low cost, high flexibility, and ability to be tweaked until the desired result is achieved.
CGI is often paired with traditional special effects, usually in the form of computer-generated sets or props for actors to interact with. Learn how to use CGI on your movies.
