Many of you get confused about that CGI & VFX are the same thing or not. Well, it's not, there's a huge difference between them. CGI is computer generated image where any shot is totally created with computer, there is nothing shot using camera. The editors make 3D Models using computer & turn them into a realistic object. On the other hand, VFX is actually visual effects used in videos. Live action reference footages are edited or replaced or turned into a different environment using VFX.
