A3D (Aureal 3-Dimensional) is a technology developed by Aureal that delivers sound with a three-dimensional effect through headphones, two or even four speakers. Many modern sound cards and PC games used to support this feature, but this number has stopped growing due to Aureal's demise. ...more on Wikipedia about "A3D"
Aaton is a motion picture equipment manufacturer, based in Grenoble, France. Aaton was founded by Eclair engineer Jean-Pierre Beauviala, whose efforts have been primarily focused on making quiet, portable motion picture hardware suitable for impromptu field use, as for documentaries. A theoretical model for all motion picture cameras they have produced is the "cat-on-the-shoulder," a small, light, quiet motion picture camera easily operated by a single cinematographer. ...more on Wikipedia about "Aaton"
The Academy ratio of 1.37:1 is the standard aspect ratio of a 35mm film frame when used with 4-perf pulldown, and was standardized by the Academy of Motion Picture Arts and Sciences as the standard film aspect ratio in 1932, although it was used as early as 1928. ...more on Wikipedia about "Academy ratio"

Anamorphic widescreen is a cinematography and photography technique for capturing a widescreen picture on standard 35mm film. It can also refer to a related technique for maximizing picture quality in DVD video recordings. ...more on Wikipedia about "Anamorphic widescreen"
A motion picture camera specially adapted for frame-by-frame shooting animation or stop motion, also called a rostrum camera. It consists of a camera body with lens and film magazines, a stand that allows the camera to be raised and lowered, and a table, often with both top and underneath lighting. The artwork to be photographed is placed on this table. ...more on Wikipedia about "Animation camera"
The Arriflex D-20 is a film-style digital high definition movie camera made by Arri first introduced in November 2005. The camera's unique advantage is the size and type of its sensor. Instead of a standard CCD, the new Arriflex uses a single CMOS sensor, which also has the size of a 35mm negative frame. The 35mm frame means that identical lenses yield the same field of view and depth of field as that of a “regular” 35mm ARRI film camera. The camera supports 1080p (1920x1080), variable shutter angles, and a range of speeds (3-60 FPS). The optical components of the camera were essentially bastardized from other Arri film camera models (most notably the Arricam, 435 ES, and 535), which enabled quick design on proven parts. The electronic processing units are modularly constructed into three separate sections which will allow for the bodies to be upgraded by Arri as new technologies emerge without needing to design a new model camera from scratch. As of yet, Arri only plans to rent the camera out. ...more on Wikipedia about "Arriflex D-20"

Back porch refers to the portion in each scan line of a video signal between the end (rising edge) of the horizontal sync pulse and the start of active video. It was originally allocated to allow the slow electronics in early televisions time to respond to the sync pulse and prepare for the active line period. ...more on Wikipedia about "Back porch"

Bluescreen (also known as Chroma Key) is a term for the filmmaking technique of shooting foreground action against an evenly-lit monochomatic background for the purpose of removing the background from the scene and replacing it with a different image or scene. The term also refers to the visual effect resulting from this technique as well as the colored screen itself (although it is often not blue; for example, with greenscreen). ...more on Wikipedia about "Bluescreen"
Bolex is a Swiss company that manufactures motion picture cameras and lenses, the most notable products of which are in the 16 mm and Super 16 mm formats. Bolex cameras were particularly important for early television news, nature films, documentaries and the avant garde, and are still favoured by many animators today. Whilst some later models are electrically powered, the majority of those manufactured since the 1930s use a spring-wound clockwork motor. ...more on Wikipedia about "Bolex"
Burnt-in timecode (often abbreviated to BITC by analogy to VITC) is a human-readable on-screen version of the timecode information for a piece of material superimposed on a video image. BITC is sometimes used in conjunction with "real" machine-readable timecode, but more often used in copies of original material on to a non-broadcast format such as VHS, so that the VHS copies can be traced back to their master tape and the original time codes easily located. ...more on Wikipedia about "Burnt-in timecode"
The camera control unit (CCU) is installed in the production control room (PCR), and allows various aspects of the video camera on the studio floor to be controlled remotely. The most commonly made adjustments are for white balance and aperture, although almost all technical adjustments are made from controls on the CCU rather than on the camera. This frees the camera operator to concentrate on composition and focus, and also allows the technical director of the studio to ensure uniformity between all the cameras. ...more on Wikipedia about "Camera control unit"
The Computer Animation Production System (CAPS) is a proprietary collection of software programs, camera systems and custom desks developed by The Walt Disney Company together with Pixar in the late- 1980s.

Celluloid is the name of a class of compounds created from nitrocellulose and camphor, plus dyes and other agents, generally regarded to be the first thermoplastic. Easily molded and shaped, there are suggestions that celluloid was first made as an ivory replacement. Celluloid is highly flammable and also easily decomposes, and is no longer widely used. ...more on Wikipedia about "Celluloid"
A channel 3/4 output was a common output selection for most audiovisual devices intended to be connected to a TV using a Radio frequency (RF) signal. This channel option was provided because it was rare to have broadcast channels three and four used in the same market. The choice allowed the user to select the unused channel in their area so that the connected device would be able to provide video and audio on an RF feed to the television without excessive interference from a broadcast signal. ...more on Wikipedia about "Channel 3/4 output"
A character generator (CG for short) is a device or software that produces static or animated text (such as crawls and rolls) for keying into a video stream. Modern character generators are actually computer-based, and can generate graphics as well as text. ...more on Wikipedia about "Character generator"
A chroma key is the removal of a color (or small color range) from one image to reveal another image "behind" it. The removed color becomes transparent. This technique is also referred to as "color keying", " colour-separation overlay" ("CSO"), "greenscreen" and " bluescreen". It is typically used for weather forecasts. The presenter appears to be standing in front of a large map, but in the studio it is actually a large blue or green background. ...more on Wikipedia about "Chroma key"
