How Does VFX work?

In a film, VFX is used when special effects have to be shown in a scene. To implement vissual effects, a video is first shot on a green screen, and later the desired scene is added to the background via VFX software. If we talk about the film Bahubali then the waterfall scene shown in it was shot on a green screen and later the waterfall scene was added in the background.

Why green background is used for vfx?

The clothes and objects of an actor or actress can be of any color other than green. And thus if a scene is shot on a screen of any color other than the green screen for a VFX shot, in such a situation the VFX software does not work properly on any color other than green. And in this case, if the background color is removed with the help of vfx software, it also affects the bodypart of the actor or actress. 

A major reason is that most films use green screens to act as VFX. The green color does not match the actor's natural skin and hair color, and for this reason no editing in the VFX software can be done on any actor.The green screen effect is a technique of this type, which is green and removes curtains and combines two images or videos.
