In the world of film and entertainment, there are two terms that are often used interchangeably but actually have significant differences: VFX (Visual Effects) And CGI (Computer-Generated Imagery). Both have a very important role in creating stunning visual effects on the screen, but have differences in terms of process, use and final results.
This article will discuss in detail about difference between VFX and CGI, as well as explaining why understanding these two terms is so important, especially for professionals in the entertainment, film and digital media industries.
What are Visual Effects (VFX)?
Visual Effects (VFX) is a technique used to create or manipulate images or videos that cannot be taken directly through a camera. VFX is a process that involves various techniques for adding certain visual elements to a film or video production. This includes physical effects such as explosion, building damage, extreme weather, or even fantastic characters which cannot exist in the real world.
VFX also covers compositing, namely combining various visual elements into one natural-looking image. This may include combining real and digital images, or other effects that enrich the film’s visuals.
What is Computer-Generated Imagery (CGI)?
Computer-Generated Imagery (CGI) is a specific technique in VFX that refers to creating images or animations digitally using computer software. CGI produces computer-generated 2D or 3D images, which are often used to create objects, characters, or worlds that could not exist in the real world.
For example, characters like Gollum Of The Lord of the Rings or fantasy world in Avatar is the result of CGI, which is created with special software to create realistic or imaginative images. CGI is often used for animation, 3D films, and even video games.
Key Differences between VFX and CGI
1. Definition and Scope of Use
- VFX is a general term that covers a variety of techniques and processes for creating visual effects in films and videos. It includes CGI, but also includes practical effects such as prosthetics, make-up effects, image composition, and other visual elements produced after the shooting process.
- CGI is a part of VFX that specifically refers to images or animations created using computers. CGI refers to the digital creation of elements used in films or videos.
2. Manufacturing Process
- VFX often involve various visual elements, which can be practical effects (such as physical explosions captured on camera) or digital elements added after filming was completed. VFX is a term that covers the entire visual process involving image and video manipulation.
- CGI, on the other hand, focuses on creating completely computer-generated images or animations. CGI is usually used to create worlds or objects that cannot be found in the real world, and is often used in science fiction or fantasy films.
3. Use in Film and Media
- VFX used in a wide variety of films and media to add visual elements of depth and are often necessary to enhance the cinematic experience. VFX can include major effects such as explosion, complex camera movements, or even dramatic weather effects.
- CGI focusing more on creating digital characters, virtual worlds, and other 3D elements that are an integral part of modern film production. Movies like Avatar, The Avengers, And Transformers relies heavily on CGI to create the creatures and digital world.
4. Goals and Final Results
- VFX aims to create or enrich visual elements in films, both real and imaginative. The goal is to enhance the visual narrative and transport the audience into a more dramatic or fantastical world.
- CGI, meanwhile, is often used to create completely digital objects or characters, with the aim of providing visual elements that would be impossible to achieve physically.
