What is the difference between SFX and VFX?

• A. SFX are live effects created on set, while VFX are created in post-production using computers.
• B. SFX are computer-generated in post-production, while VFX are practical effects on set.
• C. SFX and VFX are identical.
• D. SFX are sounds only; VFX are pictures.

Answer: (A)

The main idea here is the difference between practical effects produced on set and digital effects created after filming. SFX refers to practical, hands-on effects you can see in the scene—like a rain machine, a breakaway prop, a controlled explosion, or prosthetics. These are performed during the shoot and captured on camera. VFX, on the other hand, are computer-generated effects added in post-production—things like CGI creatures, digital environments, or removing wires and compositing different elements together. This distinction makes the best answer: SFX are live effects created on set, while VFX are created in post-production using computers. The other options mix up where the work happens or what each term covers: one suggests SFX are computer-generated, another says they’re identical, and another reduces SFX to sounds only, which ignores the practical, on-set nature of SFX.
