Film-making is segmented right into 3 phases. Pre-production, production, and last but not the least post-production. Pre-production is the stage where you attempt and encourage everybody that your movie (Make a 3D Computer Animation Motion Picture) will start shooting. Throughout production, every little thing takes place at once. The artists, lights, video camera, props, routine, movie supply, egos, tantrum, and all the rest.
VFX stands for Visual Effects. These are the imageries which are created in post-production. In essence, they are an image that appears in a film that could not be photographed during primary cinematography for whatever reason. Examples of VFX would be fantastical creatures whose physiology makes it impossible to create them via a “man in a monster costume”, sets that are too large and expensive to build physically or stunts that are so dangerous it’s safer to produce them in post-production via various means.
Visual effects or VFX in its most elementary form are digitally manipulated live action footage. In other words, a visual effect is the optimum use of computers to add and remove special effects or anything that wasn’t originally within the shot.
A visual effect or impact is the integration of live-action footage and generated imagery to create realistic environments. However, the creation of such imaginary would be dangerous, costly, and simply impossible to capture on film.
