Making it alive

While writing a story, a writer dreams a lot. While directing, a director have lots of thing in mind. But while making, there comes the problem. Remember the scene from Chak De, when Team India was playing at Australia, you all saw the crowd cheering up team. Do you think that the Production house actually manage to call so much people for the shot? The Army of Akbar from the initial scene from Jodha Akbar was not true. But that seems too real. If there was no army or audience, then how did we able to see what saw? The technology which used is called Visual Effects.

Visual Effects, commonly called as VFX, is the new technology which is growing and making work easy for the production and director. There are various process involved by which imagery is created and/or manipulated outside the context of a live action shoot. Visual effects involve the integration of live-action footage and generated imagery to create environments which look realistic, but would be dangerous, costly, or simply impossible to capture on film. Visual effects using computer generated imagery (CGI) have become increasingly common in big-budget films, and have also recently become accessible to the amateur filmmaker with the introduction of affordable animation and compositing software.
Visual effects are often integral to a movie’s story and appeal. Although most visual effects work is completed during post-production, it usually must be carefully planned and choreographed in pre-production and production. Visual effects are designed and edited in Post-Production, with the use of graphic design, modeling, animation and similar software, while special effects are made on set, such as explosions, car chases and so on. A visual effects supervisor is usually involved with the production from an early stage to work closely with production and the film’s director to achieve the desired effects.
Visual effects may be divided into at least four categories:
Models: miniature sets and models, animatronics, stop motion animation.
Stop motion: Stop-motion animation is used to describe animation created by physically manipulating real-world objects and photographing them one frame of film at a time to create the illusion of movement. There are many different types of stop-motion animation, usually named after the type of media used to create the animation. Computer software is widely available to create this type of animation.
Matte paintings and stills: digital or traditional paintings or photographs which serve as background plates for keyed or rotoscoped elements.
Live-action effects: keying actors or models through bluescreening and greenscreening.
Digital animation: modeling, computer graphics lighting, texturing, rigging, animating, and rendering computer-generated 3D characters, particle effects, digital sets, backgrounds.
Digital effects (commonly shortened to digital FX or FX) are the various processes by which imagery is created and/or manipulated with or from photographic assets. Digital effects often involve the integration of still photography and computer generated imagery (CGI) in order to create environments which look realistic, but would be dangerous, costly, or simply impossible to capture in camera. FX is usually associated with the still photography world in contrast to visual effects which is associated with motion film production.
