VFX stands for "Visual Effects" in film. It refers to the use of digital technology, computer-generated imagery (CGI), and other visual elements to enhance or create visual sequences that are difficult or impossible to achieve through practical means alone. VFX in film encompasses a wide range of techniques, including creating realistic environments, animating fantastical creatures, simulating natural phenomena like fire and water, and adding visual enhancements to live-action footage. VFX artists play a crucial role in the filmmaking process, using specialized software and techniques to bring imaginative worlds and extraordinary visuals to life on the big screen.
