Digital Remastering
Remaster refers to changing the quality of the sound or of the image, or both, of previously created recordings, either audiophonic, cinematic, or videographic. The terms digital remastering and digitally remastered are also used. Mastering A master is the definitive recording version that will be replicated for the end user, commonly into other formats (e.g. LP records, CDs, DVDs, Blu-rays). A batch of copies is often made from a single original master recording, which might itself be based on previous recordings. For example, sound effects (e.g. a door opening, punching sounds, falling down the stairs, a bell ringing) might have been added from copies of sound effect tapes similar to modern sampling to make a radio play for broadcast. Problematically, several different levels of masters often exist for any one audio release. As an example, examine the way a typical music album from the 1960s was created. Musicians and vocalists were recorded on multi-track tape. This tape w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Album
An album is a collection of audio recordings issued on compact disc (CD), Phonograph record, vinyl, audio tape, or another medium such as Digital distribution#Music, digital distribution. Albums of recorded sound were developed in the early 20th century as individual Phonograph record#78 rpm disc developments, 78 rpm records collected in a bound book resembling a photograph album; this format evolved after 1948 into single vinyl LP record, long-playing (LP) records played at revolutions per minute, rpm. The album was the dominant form of recorded music expression and consumption from the mid-1960s to the early 21st century, a period known as the album era. Vinyl LPs are still issued, though album sales in the 21st-century have mostly focused on CD and MP3 formats. The 8-track tape was the first tape format widely used alongside vinyl from 1965 until being phased out by 1983 and was gradually supplanted by the cassette tape during the 1970s and early 1980s; the populari ...

Generation Loss
Generation loss is the loss of quality between subsequent copies or transcodes of data. Anything that reduces the quality of the representation when copying, and would cause further reduction in quality on making a copy of the copy, can be considered a form of generation loss. File size increases are a common result of generation loss, as the introduction of artifacts may actually increase the entropy of the data through each generation. Analog generation loss In analog systems (including systems that use digital recording but make the copy over an analog connection), generation loss is mostly due to noise and bandwidth issues in cables, amplifiers, mixers, recording equipment and anything else between the source and the destination. Poorly adjusted distribution amplifiers and mismatched impedances can make these problems even worse. Repeated conversion between analog and digital can also cause loss. Generation loss was a major consideration in complex analog audio and video ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4K Resolution
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K Ultra-high-definition television, UHD) is the dominant 4K standard, whereas the digital cinema, movie projection industry uses 40962160 (Digital Cinema Initiatives, DCI 4K). The 4K television market share increased as prices fell dramatically during 2014 and 2015. 4K standards and terminology The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p". While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 ...

2K Resolution
2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels. In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines 2K resolution as . For television and consumer media, is the most common 2K resolution, but this is normally referred to as 1080p. Resolutions Standards and terminology In the cinematography industry, 2K resolution traditionally refers to a digital scan of 35mm film with a resolution around 2000 pixels wide. Typically this is done at , but the exact dimensions vary based on the aspect ratio and size of the scan area. Another common 2K resolution in cinema is . This is the resolution of the 2K container format standardized by DCI in their Digital Cinema System Specification in 2005. The resolution of the encapsulated video content follows the SMPTE 428-1 standard, which establishes the following resolutions for a 2K distribution: * (full fr ...

Blu-ray
The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format. It was invented and developed in 2005 and released on June 20, 2006 worldwide. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The polycarbonate disc is in diameter and thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-l ...

Loudness War
The loudness war (or loudness race) is a trend of increasing audio levels in recorded music, which reduces audio fidelity and—according to many critics—listener enjoyment. Increasing loudness was first reported as early as the 1940s, with respect to mastering practices for 7-inch singles. The maximum peak level of analog recordings such as these is limited by varying specifications of electronic equipment along the chain from source to listener, including vinyl and Compact Cassette players. The issue garnered renewed attention starting in the 1990s with the introduction of digital signal processing capable of producing further loudness increases. With the advent of the compact disc (CD), music is encoded to a digital format with a clearly defined maximum peak amplitude. Once the maximum amplitude of a CD is reached, loudness can be increased still further through signal processing techniques such as dynamic range compression and equalization. Engineers can apply an incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HowStuffWorks
HowStuffWorks is an American commercial infotainment website founded by professor and author Marshall Brain, to provide its target audience an insight into the way many things work. The site uses various media to explain complex concepts, terminology, and mechanisms—including photographs, diagrams, videos, animations, and articles. The website was acquired by Discovery Communications in 2007 but was sold to Blucora in 2014. The site has since expanded out into podcasting, focusing on factual topics. In December 2016, HowStuffWorks, LLC became a subsidiary of OpenMail, LLC, later renamed System1.

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitrate
In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). The non-standard abbreviation bps is often used to replace the standard symbol bit/s, so that, for example, 1 Mbps is used to mean one million bits per second. In most computing and digital communication environments, one byte per second (symbol: B/s) corresponds to 8 bit/s. Prefixes When quantifying large or small bit rates, SI prefixes (also known as metric prefixes or decimal prefixes) are used, thus: Binary prefixes are sometimes used for bit rates. The International Standard ( IEC 80000-13) specifies different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Films
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
