How does VFX work?

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 any color other than green. And thus if a scene is shot on a screen of a color other than green for a VFX shot, in such a situation the VFX software does not work properly on any color other than green.

Why green background is used for VFX?

And in such a situation, if the background color is removed with the help of vfx software, then it also affects the body part of the actor or actress, that means if any color other than green screen will be used, then during video editing the actor or actress The color of the clothes or hair is also likely to be affected.

A major reason is that most of the movies use green screen to act as VFX. The green color does not match the natural skin and hair color of the actor, and for this reason no editing can be done in the VFX software on any actor. The green screen effect is one such technique, which is green and removes the screen and combines two pictures or videos.
