VFX vs. CGI: Know the Difference

By Hifza Nasir & Dua Fatima || Published on September 20, 2025

VFX encompasses the broader category of visual effects in filmmaking, including practical effects, while CGI refers specifically to computer-generated imagery used within VFX.

Key Differences

VFX, or visual effects, refer to the various processes by which imagery is created or manipulated outside the context of a live-action shot. These can include practical effects (like miniatures and explosions) and digital effects. CGI, or computer-generated imagery, is a subset of VFX that exclusively uses computer software to create or enhance images. It's one of the many tools used in the VFX arsenal.

VFX is employed to integrate the created imagery into real-world scenes, making the effect look realistic as if it were actually part of the live shot, CGI focuses on creating purely digital elements from scratch. For example, VFX might involve combining CGI dragons with live-action footage in a fantasy film to make them appear as if they are interacting with the real world.

CGI has revolutionized how filmmakers bring imaginative concepts to life, offering unparalleled precision and control. It allows for the creation of detailed characters, environments, and objects that would be impossible or impractical to achieve through physical means alone. VFX, on the other hand, might still utilize physical components, like models or prosthetics, combined with digital enhancements to achieve the desired effect.

The choice between using CGI or other VFX techniques often depends on the specific needs of the project. CGI offers consistency and flexibility, especially for scenes that would be too dangerous, expensive, or impossible to film in reality. VFX, encompassing both digital and practical effects, provides a broader toolkit for filmmakers to achieve their vision, sometimes opting for practical effects for a more grounded or authentic feel.

Both VFX and CGI require significant skill, creativity, and technology, but they cater to different aspects of the visual effects process. VFX is about the integration of all visual elements into cohesive final shots, while CGI is concerned with the creation of those digital elements.
