There are a few special effects that pop up over and over again in the media that’s seen today. Here are just some of the effects created by VFX software that you may have seen in your favorite pieces of media.
Stop motion is an animation technique that involves playing many still images in a row, giving the still photos on the screen the illusion of movement. In movies, stop motion used to involve someone moving a clay figure or puppet between frames to achieve this illusion, as was done in “The Nightmare Before Christmas”. Nowadays, much of this can be achieved through CGI, like “The Lego Movie”. Having said that, some video-creating software will make it simple for you to create stop-motion animation without having to learn the ins-and-outs of CGI.
Bullet-time, which is also called time-slicing, grew popular after its effective use in “The Matrix” trilogy. Bullet-time allows for the extreme distortion of time and space, giving the audience the illusion that they’re able to see events that are normally imperceptible, like a bullet flying by. To achieve this effect without video effects software is extremely difficult since the camera would have to go impossibly fast, or you may have to purchase extremely expensive camera equipment. Bullet-time effects can also be found in broadcast advertisements and video games.
Slow motion is different from bullet-time since it doesn’t aim to make the audience feel a distortion of time and space. Bullet-time involves the camera panning around a subject in real-time while the subject itself is going super slowly; this creates that “distorted” effect. Slow motion usually involves a simple static or tracking shot that can be slowed down using special effects software.
Chroma key, more commonly known as the use of “green screen,” is widely used by professionals in the movie industry and by online video-makers at home. This allows you to composite two images based on color hues. Many movies make use of chroma key, since they mitigate the costs and labor that’s needed to create huge set pieces. Movies with exotic or fantastical locations are a great example of this; think “The Lord of the Rings” or the “Harry Potter” series, which uses chroma key effects to give the illusion that the actors are standing in huge castles or inside gigantic caverns.
Digital compositing involves using video effects software to assemble multiple images to make a final image. Both print media and movies use digital compositing. “Independence Day” used digital compositing to brilliant effect, making viewers feel like they were truly seeing an alien invasion in action. The digital compositing in “Independence Day” seamlessly combined digital movie effects with miniatures and real actors.
CGI has exploded in popularity, thanks to studios like Pixar breaking new ground in the world of computer animation. Just take a look at movies like “The Incredibles” or “Monster’s Inc” to get an idea of what CGI can do: both movies include hair and fur that reacts naturally to its environment and fabric that folds and tears realistically. This type of animation would only be possible at a large scale with the use of special effects programs. CGI can also be used in print media and video games.
