SFX, or special effects, are practical effects like makeup and explosions done on set during filming. VFX, or visual effects, are created with computer software after filming to add things like spaceships or dragons that don’t exist in real life. SFX is about real, live-action effects, while VFX is digital and added in post-production. Similar to the old fashioned technique of rotoscoping, visual effects artists today can use live action reference to create more realistic CGI. The technology has been around for a number of years but the capabilities seem to leap even further every year.

Practical effects can also help actors get into character by providing them with tangible objects to interact with on set.
