How does VFX work?

In a film, VFX is used when special effects have to be shown in a scene. To implement VFX, 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.

When was VFX first used?

The first VFX in the world: was produced by Oscar Rejection in 1857, combining 32 negative elements into one image and creating a montage combination print.
The first VFX in India: The Gentleman Movie was the first film in India to use vfx, the film depicts the condition of a teenager's heart after a bomb explosion through computer graphics.But the first such film in India which used VFX in large quantity is the Ammoru film of The Telugu film industry, which was released in 1955. and Kodi  Ramakrishna Directed this film.
Vfx was first used in the Bollywood industry in India in Ajay Devgan's film "Pyaar To Hona Hi Tha", this was told by Ajay Devgan himself in an interview.

Why only 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.

Suppose a waterfall scene is to be added to the film, and there is not even such a big budget, so that all the scenes are shot realistically, in which case the scene is shot on a green screen, and with the help of vfx software, the green curtain is removed and the seascape is added there.
