A practical effect is a special effect produced physically, without computer-generated imagery or other post-production techniques. In some contexts, "special effect" is used as a synonym of "practical effect", in contrast to "visual effects" which are created in post-production through photographic manipulation or computer generation.

Many of the staples of action movies are practical effects. Gunfire, bullet wounds, rain, wind, fire, and explosions can all be produced on a movie set by someone skilled in practical effects. Non-human characters and creatures produced with make-up, prosthetics, masks, and puppetsin contrast to computer-generated imagesare also examples of practical effects.

A film crew is a group of people, hired by a production company, for the purpose of producing a film or motion picture. The crew is distinguished from the cast, as the cast are understood to be the actors who appear in front of the camera or provide voices for characters in the film. The crew is also separate from the producers, as the producers are the ones who own a portion of either the film studio or the film's intellectual property rights. A film crew is divided into different departments, each of which specializes in a specific aspect of the production. Film crew positions have evolved over the years, spurred by technological change, but many traditional jobs date from the early 20th century and are common across jurisdictions and filmmaking cultures.

A sound effect is an artificially created or enhanced sound, or sound process used to emphasize artistic or other content of films, television shows, live performance, animation, video games, music, or other media.

<span class="mw-page-title-main">Miniature effect</span> Special effect created for motion pictures and television programs using scale models

A miniature effect is a special effect created for motion pictures and television programs using scale models. Scale models are often combined with high speed photography or matte shots to make gravitational and other effects appear convincing to the viewer. The use of miniatures has largely been superseded by computer-generated imagery in contemporary cinema.

<span class="mw-page-title-main">Special effect</span> Illusions or tricks to change appearance

Special effects are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world. It used to be called SFX but this short form has also expanded to include “sound effects” as well.

<span class="mw-page-title-main">Prosthetic makeup</span> Techniques to create special cosmetic effects

Prosthetic makeup, which may also be referred to as special make-up effects or FX prosthesis, is the process of using prosthetic sculpting, molding, and casting techniques to create advanced cosmetic effects. Prosthetic makeup draws a straight lineage from the Stagecraft of theater and can be observed at the birth of science fiction cinema with Le Voyage dans La Lune, a 1902 French adventure short film directed by pioneer of special effects Georges Méliès.

Visual effects is the process by which imagery is created or manipulated outside the context of a live-action shot in filmmaking and video production. The integration of live-action footage and other live-action footage or CGI elements to create realistic imagery is called VFX.

<span class="mw-page-title-main">Virtual cinematography</span> CGI essentially

Virtual cinematography is the set of cinematographic techniques performed in a computer graphics environment. It includes a wide variety of subjects like photographing real objects, often with stereo or multi-camera setup, for the purpose of recreating them as three-dimensional objects and algorithms for the automated creation of real and simulated camera angles. Virtual cinematography can be used to shoot scenes from otherwise impossible camera angles, create the photography of animated films, and manipulate the appearance of computer-generated effects.

<span class="mw-page-title-main">Special effects supervisor</span>

A special effects supervisor, also referred to as a special effects director, special effects coordinator or SFX supervisor, is an individual who works on a commercial, theater, television or film set creating special effects. They are generally the department head who defers to the film's director and/or producers, and who is in charge of the entire special effects team. Special effects include anything that is manually or mechanically manipulated. This may include the use of mechanized props, special effects makeup, props, scenery, scale models, pyrotechnics and atmospheric effects: creating physical wind, rain, fog, snow, clouds etc.

The VFX creative director is a position common in films, television programs, and computer games using a large amount of visual effects (VFX).

<span class="mw-page-title-main">Computer-generated imagery</span> Application of computer graphics to create or contribute to images

Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static or dynamic. CGI both refers to 2D computer graphics and 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects. The application of CGI for creating/improving animations is called computer animation, or CGI animation.

Amalgamated Dynamics, Inc. (ADI) is an American special effects company specializing in animatronics and prosthetic make-up, headquartered in Chatsworth, California. It was founded in 1988 by Stan Winston alumni Tom Woodruff Jr. and Alec Gillis who hails from Phoenix, Arizona. Notable work includes Death Becomes Her, for which they won an Academy Award for Best Visual Effects, Starship Troopers, which was also nominated for an Oscar, and the practical creature effects seen in the Alien franchise from Alien 3 onward. Woodruff also portrays creatures in the films ADI works on, such as the Alien.

Physically based animation is an area of interest within computer graphics concerned with the simulation of physically plausible behaviors at interactive rates. Advances in physically based animation are often motivated by the need to include complex, physically inspired behaviors in video games, interactive simulations, and movies. Although off-line simulation methods exist to solve most all of the problems studied in physically-based animation, these methods are intended for applications that necessitate physical accuracy and slow, detailed computations. In contrast to methods common in offline simulation, techniques in physically based animation are concerned with physical plausibility, numerical stability, and visual appeal over physical accuracy. Physically based animation is often limited to loose approximations of physical behaviors because of the strict time constraints imposed by interactive applications. The target frame rate for interactive applications such as games and simulations is often 25-60 hertz, with only a small fraction of the time allotted to an individual frame remaining for physical simulation. Simplified models of physical behaviors are generally preferred if they are more efficient, easier to accelerate, or satisfy desirable mathematical properties. Fine details are not important when the overriding goal of a visualization is aesthetic appeal or the maintenance of player immersion since these details are often difficult for humans to notice or are otherwise impossible to distinguish at human scales.

<span class="mw-page-title-main">Creature suit</span> Type of realistic costumes

Creature suits are realistic costumes used to disguise a performer as an animal, monster, or other being. They are used in film, television, or as costumed characters in live events. Unlike mascots, they are often made with a high degree of realism. In contrast with prosthetic makeup, which is applied to an actor's skin, the wearer is not normally visible outside their movements controlling the costume, although in some cases, part of the wearer's body is still visible.

<span class="mw-page-title-main">Bullet hit squib</span> Special effects device used to simulate a gunshot wound on an actor

A bullet hit squib or a blood squib is a practical, pyrotechnic special effect device used mainly in the film industry, TV shows and stage performances and even in first responder moulage training to simulate the appearance of a person being shot and wounded. This is achieved by blowing open a pre-scored hole on the actor's clothing and bursting a fake blood packet with a small explosion, creating an aesthetic that filmmakers and audiences alike have become accustomed to associating with a gunshot wound.

The special effects of the 1991 American science fiction action film Terminator 2: Judgment Day were developed by four core groups: Industrial Light & Magic (ILM), Stan Winston Studio, Fantasy II Film Effects, and 4-Ward Productions. Pacific Data Images and Video Images provided some additional effects.

Ron Thornton (1957–2016) was a pioneer in the field of computer-generated visual effects for film and television. He is best known for pioneering the use of Computer Generated Imagery (CGI) in the industry, through his work on the Babylon 5 series, which was the first television series to use CGI for all its visual effects. Thornton and his team won an Emmy award in 1993 for their work in the field. During his career, Thornton also worked with teams providing visual effects for many major science fiction productions, including Doctor Who, Blake's 7, Star Trek, and Buffy the Vampire Slayer.
