Post-production
Post-production is part of the process of filmmaking, video production, audio production, and photography. Post-production includes all stages of production occurring after principal photography or recording individual program segments. The first part of the post-production process is the traditional non-linear (analog) film editing at the outset of post-production has mostly been replaced by digital or video editing software that operates as a non-linear editing (NLE) system.
Ambisonics
Ambisonics is a full-sphere surround sound format: in addition to the horizontal plane, it covers sound sources above and below the listener. Unlike some other multichannel surround formats, its transmission channels do not carry speaker signals. Instead, they contain a speaker-independent representation of a sound field called B-format, which is then decoded to the listener's speaker setup. This extra step allows the producer to think in terms of source directions rather than loudspeaker positions, and offers the listener a considerable degree of flexibility as to the layout and number of speakers used for playback.
Stereophonic sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term stereophonic also applies to systems with more than two channels or speakers such as quadraphonic and surround sound.
Sound localization
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or intensity difference) between the ears, and spectral information.
Auditory processing disorder
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome or auditory disability with normal hearing (ADN), is a neurodevelopmental disorder affecting the way the brain processes sounds. Individuals with APD usually have normal structure and function of the outer, middle, and inner ear (peripheral hearing). However, they cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech.
Cocktail party effect
The cocktail party effect is the phenomenon of the brain's ability to focus one's auditory attention on a particular stimulus while filtering out a range of other stimuli, such as when a partygoer can focus on a single conversation in a noisy room. Listeners have the ability to both segregate different stimuli into different streams, and subsequently decide which streams are most pertinent to them. It has been proposed that one's sensory memory subconsciously parses all stimuli and identifies discrete pieces of information by classifying them by salience.
3D rendering
3D rendering is the 3D computer graphics process of converting 3D models into 2D images on a computer. 3D renders may include photorealistic effects or non-photorealistic styles. Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. Several different, and often specialized, rendering methods have been developed.
Production company
A production company, production house, production studio, or a production team is a studio that creates works in the fields of performing arts, new media art, film, television, radio, comics, interactive arts, video games, websites, music, and video. These groups consist of technical staff to produce the media, and are often incorporated as a commercial publisher. Generally the term refers to all individuals responsible for the technical aspects of creating a particular product, regardless of where in the process their expertise is required, or how long they are involved in the project.
Subpixel rendering
Subpixel rendering is used to increase the apparent resolution of a computer's display. It takes advantage of the fact that each pixel on a color liquid crystal display (LCD) or similar is composed of individual red, green, and blue components — subpixels — with different locations, so that the color also causes the image to shift in space. A single pixel on a color display is made of several subpixels, typically three arranged left-to-right as red, green, blue (RGB).
Pre-production
Pre-production is the process of planning some of the elements involved in a film, television show, play, or other performance, as distinct from production and post-production. Pre-production ends when the planning ends and the content starts being produced. Filmmaking#Pre-production Pre-production formally begins once a project has been greenlit. It involves finalizing the script, hiring the actors and crew, finding locations, determining what equipment is needed, and figuring out the budget.
