What is CGI ?
Computer-Generated Imaging (CGI) is a technology that utilizes computer software to create still or animated visual content, such as images, characters, scenes, and special effects in movies, television, games, advertising, architecture, engineering, virtual reality, and art.
- CGI includes both 2D and 3D graphics, with 3D graphics being more commonly associated with CGI due to its ability to create lifelike characters and environments.
- CGI has become an indispensable tool across numerous industries, enabling the production of visually stunning content while pushing the boundaries of creativity and innovation.
- The origins of CGI trace back to the 1950s, with the earliest examples appearing in films like Alfred Hitchcock's Vertigo (1958).
- As technology improved, CGI gained prominence in Hollywood, becoming a staple in blockbuster films and leading to advancements in fields like virtual cinematography and real-time rendering.
- With the advent of powerful hardware and sophisticated software, CGI has become accessible to individuals and small companies, allowing them to create engaging content without needing massive studio resources.

Some common criticisms of CGI in film and television include
Unnatural or Unconvincing Effects: If CGI effects look too artificial or unconvincing, they can take audiences out of the story, making it challenging for viewers to suspend their disbelief and fully engage with the narrative.
Overuse: Heavy reliance on CGI can lead to films and TV shows feeling overly stylized and artificial, making it difficult for audiences to relate to the characters or story, ultimately detracting from the viewing experience.
Cost and Time-Consuming: Creating complex CGI effects requires significant resources and skilled labor, which can drive up production budgets and delay release schedules, posing challenges for independent filmmakers and smaller productions.
Substitute for Genuine Storytelling: When CGI is used excessively, it can become a substitute for authentic storytelling, potentially leading to a focus on visual effects over character development and narrative depth.
What is VFX ?
Visual effects (VFX) refer to the process of creating or manipulating imagery outside the context of a live-action shot in filmmaking to add a sense of realism to visual storytelling. VFX involve the integration of live-action footage and computer-generated imagery (CGI) to create realistic environments, characters, and scenarios that would otherwise be impossible or unsafe to capture on film. Examples of VFX include creating fantastical creatures, simulating natural phenomena such as storms, and removing unwanted elements from live-action footage. VFX are commonly used in feature films, television series, and advertisements, and they have evolved significantly since the advent of computer-generated imagery in the 1980s.
"Difference Between CGI and VFX"
CGI (Computer-Generated Imagery):
Definition: CGI refers to anything created digitally on a computer platform, encompassing images in various media like films, games, videos, animations, and commercials.
Usage: CGI is more commonly associated with 3D computer graphics but can also be used for 2D images, both static and dynamic.
Creation: CGI images are developed using computer graphics software and can be incorporated into VFX shots in live-action movies to create realistic 3D models and environments.
VFX (Visual Effects):
Definition: VFX involves manipulating computer-generated images and live-action footage to create visual effects for films and animations.
Usage: VFX enhances live-action footage by adding elements that are impractical or impossible to capture physically, such as imaginary creatures or environments.
Creation: VFX images are created through CGI, giving them a natural look and seamlessly integrating them with live-action shots to enhance visual storytelling.
Key Differences:
Purpose: VFX enhances live-action footage, while CGI empowers the creation of digital imagery like characters and environments.
Creation Process: VFX involves manipulating both computer-generated images and live-action shots, while CGI specifically focuses on digitally created content.
Integration: CGI is a subset of VFX, with CGI images often being used within VFX shots to create realistic effects in movies and TV shows.
In summary, while CGI focuses on creating digital imagery using computer graphics, VFX involves integrating these computer-generated images with live-action footage to enhance visual storytelling in films and television productions.
