You might have seen films with heavy visual effects and heard people say “The visual effects were amazing!”, but what exactly are visual effects and how do they work? In this post, I’m going to give you a rough overview of the possibilities that visual effects can offer, then we’ll go into more detail in the next posts..
According to VES handbook: Visual effects (commonly shortened to Visual FX or VFX) is the term used to describe any imagery created, altered, or enhanced for a film or other moving media that cannot be accomplished during live-action shooting. In other words, much of the art of visual effects takes place in post-production, after primary image capture is complete. Visual effects can be added to live-action, captured through techniques such as matte painting; rear- and front-screen projection; miniature or forced perspective sets; computer graphic objects, characters, and environments; and compositing of images recorded in any number of ways. The recent explosion in digital tools that make flawless compositing, digital sets, and fully computer-generated characters possible and accessible to moving image makers at all levels has made visual effects a standard part of every moving image maker’s tool kit.
“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 has recently become accessible to the Independent filmmaker with the introduction of affordable animation and compositing software. So basically, anything that’s difficult to film then we use visual effects to achieve it. For example, aliens attacking the earth is impossible to film so we use visual effects for all the alien creatures to destroy the city. This is a very obviously example of visual effects. A lot of time we use visual effects in more subtle areas. For example, if there’s a scene in the story that needs to be in another country, an imaginary location or a city in the future/past. It’s just inefficiency to go to another country or build a set. Visual effects in these situation are really helpful. A lot of visual effects examples will be discussed in the future posts. Here we just need to have a rough concept of what visual effects is about and why we use it for films. We hope you enjoyed this post and please feel free to leave us any comments.
