Traveling Matte
Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting. In film and stage, mattes can be physically huge sections of painted canvas, portraying large scenic expanses of landscapes. In film, the principle of a matte requires masking certain areas of the film emulsion to selectively control which areas are exposed. However, many complex special-effects scenes have included dozens of discrete image elements, requiring very complex use of mattes and layering mattes on top of one another. For an example of a simple matte, the director may wish to depict a group of actors in front of a store, with a massive city and sky visible above the store's roof. There would be two images—the actors on the set, and the ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norman Dawn
Norman O. Dawn (25 May 1884 – 2 February 1975) was an early American film director. He made several improvements on the matte shot to apply it to motion picture, and was the first director to use rear projection in film production. Dawn's innovations in glass and matte shots Dawn's first film ''Missions of California'' made extensive use of the glass shot, in which certain parts of the intended image are painted on a piece of glass and placed in between the camera and the live action. Many of the buildings which Dawn was filming were at least partially destroyed; by painting sections of roof or walls, the impression was made that the buildings were in fact, still whole. The main difference between the glass shot and the matte shot is that with a glass shot, all filming is done with a single exposure of film. Dawn combined his experience with the glass shot with the techniques of the matte shot. Up until this time, the matte shot was essentially a double-exposure: a section o ...

Young Sherlock Holmes
''Young Sherlock Holmes'' (also known with the title card name of ''Young Sherlock Holmes and the Pyramid of Fear'') is a 1985 American mystery adventure film directed by Barry Levinson and written by Chris Columbus, based on the characters created by Sir Arthur Conan Doyle. The film depicts a young Sherlock Holmes and John Watson meeting and solving a mystery together at a boarding school. The film is notable for being the first full-length movie to feature a completely computer-generated character, created by Lucasfilm's Graphics Group. This was a historical landmark in special effects history and influenced other CGI future films such as Pixar's ''Toy Story''. At the 58th Academy Awards for films produced in 1985, the film was nominated for Best Visual Effects ( Dennis Muren, Kit West, John R. Ellis, and David W. Allen). Plot Following the closure of his old school in the countryside, a young John Watson enrolls at London’s Brompton Academy, where Sherlock H ...

Analog Signal
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., ''analogous'' to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves. In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values. Digital sampling imposes some bandwidth and dynamic range constraints on the representation and adds quantization noise. The term ''analog signal'' usually refers to electrical signals; however, mechanical, pneumatic, hydraulic, and other systems may also convey or be considered analog signals. Representation An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, ...

Optical Printer
An optical printer is a device consisting of one or more film projectors mechanically linked to a movie camera. It allows filmmakers to re-photograph one or more strips of film. The optical printer is used for making visual effects for motion pictures, or for copying and restoring film material. Common optical effects include fade outs and fade ins, dissolves, slow motion, fast motion, and matte work. More complicated work can involve dozens of elements, all combined into a single scene. History The first commercially available, although not mass produced, optical printer appeared in 1927 and was called the Depue & Vance Daylight Optical Printer. It was mainly used to reduce standard prints to 16mm and allowed for operation without a darkroom except for loading the positive film magazine. In 1918, the cinematographer Carl Gregory came upon a printer made by G. J. Badgley of New York, designed to produce copies of a standard film using domestic size film stock. Realizing the p ...

Alpha Compositing
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated '' matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-linear Editing System
Non-linear editing (NLE) is a form of offline editing for audio, video, and image editing. In offline editing, the original content is not modified in the course of editing. In non-linear editing, edits are specified and modified by specialized software. A pointer-based playlist, effectively an edit decision list (EDL), for video and audio, or a directed acyclic graph for still images, is used to keep track of edits. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited. A non-linear editing system is a video editing (NLVE) program or application, or an audio editing (NLAE) digital audio workstation (DAW) system. These perform non ...

Motion Control
Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner. Motion control systems are extensively used in a variety of fields for automation purposes, including precision engineering, micromanufacturing, biotechnology, and nanotechnology. The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators. Motion control may be open loop or closed loop. In open loop systems, the controller sends a command through the amplifier to the prime mover or actuator, and does not know if the desired motion was actually achieved. Typical systems include stepper motor or fan control. For tighter control with more precision, a measuring device may be added to the system (usually near the end motion). When the measurement is converted to a signal that is sent back to the controller, and the controller compensates for any error, it becomes a C ...

Petro Vlahos
Petro Vlahos (; August 20, 1916 – February 10, 2013) was an American engineer and inventor, considered to be one of the pioneering scientific and technical innovators of the motion picture and television industries. He is remembered in particular for creating the Ultimatte process, which refined the colour process known as chroma keying (i.e. "bluescreening"). In recognition of his contributions, he was awarded multiple Oscars, as well as an Emmy Award. Early life Vlahos was born in Raton, New Mexico, the son of Greek immigrants. He showed an early aptitude for electronics and ham radio, and in 1941, he gained his Engineering degree from the University of California at Berkeley. He worked as a designer for Douglas Aircraft in World War II, and later as a radar engineer at Bell Laboratories. After the war, he moved to Hollywood and worked for MGM.

Academy Award For Best Visual Effects
The Academy Award for Best Visual Effects is presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS) for the best achievement in visual effects. It has been handed to four members of the team directly responsible for creating the film's visual effects since 1980. History The Academy of Motion Picture Arts and Sciences first recognized the technical contributions of special effects to movies at its inaugural dinner in 1929, presenting a plaque for "Best Engineering Effects" to the first Best Picture Oscar winner, the World War I flying drama '' Wings''. Producer David O. Selznick, then production head at RKO Studios, petitioned the Academy Board of Governors to recognize the work of animator Willis O'Brien for his groundbreaking work on 1933's '' King Kong''. However, the Academy did not have a category to acknowledge its visual achievements at the time. It was not until 1938 when a film was actually recognized for its effects work, when a "Special Achieve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
