Question 1

What does VFX stand for?

Accepted Answer

VFX stands for visual effects. It describes any imagery created or altered digitally and combined with live-action footage, usually in post-production. Green screen compositing, motion tracking, rotoscoping, matte painting, digital set extensions, and CGI all fall under VFX.

Question 2

What does CGI stand for?

Accepted Answer

CGI stands for computer-generated imagery. It refers to images, characters, objects or environments built entirely in software, such as 3D creatures, digital cities or simulated fire and water. CGI can stand alone in fully animated films or be blended into live-action footage as part of VFX.

Question 3

What does SFX mean in movies?

Accepted Answer

In movies, SFX means special effects: physical effects created on set and captured by the camera, like pyrotechnics, prosthetic makeup, animatronics and rigged stunts. In video editing and audio work, SFX usually means sound effects, the recorded or designed sounds added in post-production.

Question 4

Is CGI the same as VFX?

Accepted Answer

No. CGI is a subset of VFX. CGI refers to elements built entirely in software, like 3D models and animations, while VFX is the broader process of creating or altering imagery digitally and combining it with live-action footage. All CGI used in live-action film is VFX, but not all VFX is CGI.

Question 5

What is the difference between visual effects and special effects?

Accepted Answer

Visual effects (VFX) are created digitally, mostly in post-production, while special effects (SFX) are practical effects performed on set during filming, such as explosions, prosthetics and animatronics. Many modern films combine both, for example a real explosion on set enhanced with digital fire and debris.

Question 6

Is CGI better than practical effects?

Accepted Answer

Neither is better in every case. CGI offers limitless creative freedom and can be changed in post, while practical effects give real light, weight and actor reactions that often age better on screen. Most modern films blend the two, choosing each based on budget, safety and the realism a shot needs.
