Both VFX vs CGI are used in the film and television industry to create realistic images that would otherwise be impossible to capture.
VFX, or visual effects, refers to the process of creating images that are not physically possible, such as adding computer-generated objects into a live-action scene.
CGI, or computer-generated imagery, refers to the process of creating images that are completely computer-generated, such as an animated character or a detailed background.
In film and video games, visual effects (abbreviated as VFX) are the processes by which imagery is created and/or manipulated outside the context of a live-action shot. Visual effects involve the integration of live-action footage (special effects) and generated imagery (digital or optical effects) to create environments that 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 filmmakers and have been used in some of the most expensive films of all time.
Some of the most common examples of visual effects include computer-generated imagery (CGI), matte paintings, and 3D animation. CGI is used extensively in movies and video games to create characters, environments, and special effects.
Visual effects are often integral to the telling of a story and can be used to create atmosphere, enhance the action, or further the plot. They can be used to make the impossible seem real, or to make the real seem surreal.
What is VFX?
VFX stands for visual effects.
Visual effects are the processes and techniques used to create images and animations that cannot be created using traditional photography or filmmaking techniques. This can include anything from creating the illusion of a character flying through the air to make a scene look as if it is taking place in a different location entirely.
What is CGI?
Computer-generated imagery (CGI) is a digital image that is created by a computer. This can be a 3D model of something or a photo that has been manipulated to look like it is a different photo.
Difference between CGI and VFX
VFX is short for visual effects. CGI is short for computer-generated imagery. Both VFX and CGI are used to create images that look realistic, but they are created using different methods.
VFX artists use a combination of live-action footage and computer-generated imagery to create their effects. This can include adding explosions or other special effects to live-action footage or creating completely CG environments.
CGI artists use computers to generate their images from scratch. This means they can create any kind of environment or creature that they can imagine.
Another key difference is that VFX artists typically have more experience with traditional art forms such as painting and sculpting. While CGI artists often have more experience with computer programming and 3D modeling.
Finally, VFX artists are often more focused on the creative aspects of their work, while CGI artists tend to be more technical and focused on the technical aspects of their work.
VFX vs CGI: Key differences
History of VFX and CGI
The history of VFX and CGI is long and complicated. The first examples of VFX and CGI can be traced back to the early days of film.
One of the earliest examples of VFX and CGI can be seen in the film “Le Voyage Dans La Lune” which was released in 1902. This film featured a number of special effects, including the use of miniatures and stop-motion animation.
In the years that followed, VFX and CGI continued to evolve. A number of films were released that featured increasingly sophisticated special effects, such as “King Kong” (1933) and “The Wizard of Oz” (1939).
However, it was not until the late 1970s and early 1980s that VFX and CGI began to be used extensively in films. This was largely due to the development of new technologies, such as computer-generated imagery (CGI).
Some of the earliest examples of CGI can be seen in the films “Star Wars” (1977) and “E.T. the Extra-Terrestrial” (1982). In both of these films, CGI was used to create realistic-looking aliens and environments.
Since then, VFX and CGI have been extensively used in a wide variety of films. Some of the most iconic examples of VFX and CGI can be seen in the “Lord of the Rings” trilogy (2001-2003), the “Harry Potter” films (2001-2011), and the “Marvel Cinematic Universe” films (2008-present).
Uses of VFX
Some of the ways in which VFX can be used include:
- To create realistic or impossible environments
- To enhance or change the appearance of people or objects
- To animate objects or people
- To create special effects
- To remove objects or people from a scene
- To add objects or people to a scene
Uses of CGI
CGI is used in a variety of fields including:
- Television / Live streaming production
- Video game development
- Web design
- Graphic design
- Architectural visualization
- Product design
- Medical imaging
- Weather forecasting
VFX, CGI and the film industry
Visual effects using computer-generated imagery (CGI) have become increasingly common in big-budget films, although using natural locations and advanced equipment is still preferred in certain cases.
Some visual effects are so realistic that audiences may not even be aware that they are seeing a visual effect. For example, in the film The Lord of the Rings: The Two Towers, the character Gollum was created with CGI. He looks so real that many people believe he is a real person.
In the early days of film, visual effects were created by filming the action in front of a green screen, which is a blank screen that is used as a background. The footage would then be edited so that the blank screen would be replaced by another image, such as a landscape.
This technique is still used today, but with advances in technology, more sophisticated visual effects are possible. For example, in the film The Hobbit: An Unexpected Journey, the character of Gollum was created using motion capture, which is a process of recording the movement of an actor and then translating it into a computer-generated character.
Some visual effects are created using a process called rotoscoping. This is where footage of a live-action scene is projected onto a blank canvas and then an artist traces over the image to create a new image. This technique was used to create the animated character of rotoscoping.
With the advent of digital technology, visual effects have become more sophisticated and realistic. For example, in the film Avatar, the characters of the Navi were created using a process called motion capture, where the movements of actors were recorded and then translated into computer-generated characters.
Today, visual effects are an essential part of the filmmaking process and are used to create a wide variety of images, from environments and characters to special effects and explosions.
While we’re not sure what the future holds for CGI, VFX, and the industry behind them, we do know that there will always be a place for both. And with the rise of new technologies, we’re sure we’ve just scratched the surface of what we can do with CGI and VFX.
