VFX

Visual effects (VFX) is the process through which imagery is altered, created, or enhanced for live-action media that could not be captured during live-action filming due to it being costly, dangerous, impractical, or impossible to shoot. Visual effects allow for the integration of live-action footage and VFX to create realistic objects, characters and environments.

VFX (visual effects) encompasses any kind of effect created in post-production that wasn't shot directly on set.

Visual effects are different from special effects because visual effects require a computer and are added in after shooting. Special effects, or SFX are realized on set — they are things like purposeful and controlled explosions, fake gunshot wounds, etc.
