Digital compositingDigital compositing is the process of digitally assembling multiple images to make a final image, typically for print, motion pictures or screen display. It is the digital analogue of optical film compositing. It is a part of VFX processing.
Chroma keyChroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two or more images or video streams together based on colour hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video — particularly the newscasting, motion picture, and video game industries.
Digital imageA digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively. An image can be vector or raster type.
Computer-generated imageryComputer-generated imagery (CGI) is a specific application of computer graphics for creating or improving images in art, printed media, simulators, videos, and video games. These images are either static (i.e. still images) or dynamic (i.e. moving images). CGI both refers to 2D computer graphics and (more frequently) 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects (in films, television programs, commercials, etc.).
Natron (software)Natron is a free and open-source node-based compositing application. It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived. Natron supports plugins following the OpenFX 1.4 API. Most open-source and commercial OpenFX plug-ins are supported.
Surface weather analysisSurface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale features such as weather fronts.
Computer graphicsComputer graphics (CG) deals with generating images and art with the aid of computers. Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science.
Weather presenterA weather presenter (also known as a weather girl, weatherman or weather broadcaster) is a person who presents the weather forecast daily on radio, television or internet news broadcasts. Using tools such as projected weather maps, they inform the viewers of the current and future weather conditions, explain underlying reasons, and relay weather hazards and warnings issued for their region, country or larger areas.
Multiple exposureIn photography and cinematography, a multiple exposure is the superimposition of two or more exposures to create a single image, and double exposure has a corresponding meaning in respect of two images. The exposure values may or may not be identical to each other.
Live actionLive action is the most common form of cinematography or videography, which uses a camera to record living actors, by a camera operator under the supervision of a cinematographer. Live action is used to define film, video games or similar visual media. Live action is in contrast with animations. Some works combine live action with animation to create a live-action animated feature film.
Georges MélièsMarie-Georges-Jean Méliès ( , French:; 8 December 1861 – 21 January 1938) was a French filmmaker, actor, magician, and toymaker. He led many technical and narrative developments in the early days of cinema, primarily in the fantasy and science fiction genres.
Television studioA television studio, also called a television production studio, is an installation room in which video productions take place, either for the production of live television and its recording onto video tape or other media such as SSDs, or for the acquisition of raw footage for post-production. The design of a studio is similar to, and derived from, movie studios, with a few amendments for the special requirements of television production.
