Video Editing
Video editing is the post-production and arrangement of video shots. To showcase excellent video editing to the public, video editors must be reasonable and ensure they have a thorough understanding of film, television, and other sorts of videography. Video editing structures and presents all video information, including films and television shows, video advertisements and video essays. Video editing has been dramatically democratized in recent years by editing software available for personal computers. Editing video can be difficult and tedious, so several technologies have been produced to aid people in this task. Overall, video editing has a wide variety of styles and applications. Types of editing Though once the province of expensive machines called video editors, video editing software is now available for personal computers and workstations. Video editing includes cutting segments (trimming), re-sequencing clips, and adding transitions and other special effects. * Linear ...

Video
Video is an Electronics, electronic medium for the recording, copying, playback, broadcasting, and display of moving picture, moving image, visual Media (communication), media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types. Video systems vary in display resolution, Display aspect ratio, aspect ratio, refresh rate, color capabilities, and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcasts, magnetic tape, optical discs, Video file format, computer files, and Streaming media, network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mecha ...

Real-time Video Editing
Real-time video editing is a system of editing video where it takes no longer to render a video than the length of that video clip itself. Live video editing is where there are various cameras at various angles and position, capturing single or multiple subjects and the footage is routed through a vision mixing device and edited and transmitted in real-time. Broadcasters traditionally used large, disparate computer systems for real-time video editing with multiple CPUs, multiple gigabytes of RAM and high-powered hard drives. Some had additional hardware components designed to enhance the performance of the specific video editing software being used. Other approaches used to ensure real-time playback included continuous background rendering, and using multiple networked computers to share the rendering load. These systems would allow broadcasters to edit and render a video clip in 30 minutes. These systems are now outdated thanks to the instantaneous nature of social media platforms ...

Guillotine
A guillotine ( ) is an apparatus designed for effectively carrying out executions by Decapitation, beheading. The device consists of a tall, upright frame with a weighted and angled blade suspended at the top. The condemned person is secured with a pillory at the bottom of the frame, holding the position of the neck directly below the blade. The blade is then released, swiftly and forcefully decapitating the victim with a single, clean pass; the head falls into a basket or other receptacle below. The guillotine is best known for its use in France, particularly during the French Revolution, where the revolution's supporters celebrated it as the people's avenger and the revolution's opponents vilified it as the pre-eminent symbol of the violence of the Reign of Terror. While the name "guillotine" dates from this period, similar devices had been in use elsewhere in Europe over several centuries. Use of an oblique blade and the pillory-like restraint device set this type of gui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Razor
A razor is a bladed tool primarily used in the removal of body hair through the act of shaving. Kinds of razors include straight razors, safety razors, disposable razors, and electric razors. While the razor has been in existence since before the Bronze Age (the oldest razor-like object has been dated to 18,000 BC), the most common types of razors currently used are the safety razor and the electric razor. History Razors have been identified from many Bronze Age cultures. These were made of bronze or obsidian and were generally oval-shaped, with a small tang protruding from one of the short ends.Warwickshire County Council: New Prehistoric Archaeology Objects "Even further awa ...

Ferrofluid
Ferrofluid is a dark liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended inside a carrier fluid (usually an organic solvent or water). Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of tiny nanoparticles is weak enough that the surfactant's Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually do not retain magnetization in the absence of an externally applied field and thus are often classified as " superparamagnets" rather than ferromagnets. In contrast to ferrofluids, magnetorheological fluids (MR fluids) are magnetic fluids with larger particles. That is, a ferrofluid contains primarily nanoparticles, while ...

Quadruplex Videotape
2-inch quadruplex videotape (also called 2" quad video tape or quadraplex) was the first practical and commercially successful analog recording video tape format. The format uses magnetic tape and was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. The first videotape recorder using this format was built the same year. This format revolutionized broadcast television operations and television production, since the only recording medium available to the TV industry until then was motion picture film. Since most United States network broadcast delays by the television networks at the time used kinescope film that took time to develop, the networks wanted a more practical, cost-effective, and quicker way to time shifting, time-shift television programming for later airing in Western time zones than the expensive and time-consuming processing and editing of film. Faced with these challenges, broadc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Tape Recorder
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio signal, audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. Beginning in 1963, videotape machines made instant replay during televised sporting events possible. Improved formats, in which the tape was contained inside a videocassette, were introduced around 1969; the machines which play them are called videocassette recorders. An agreement by Japanese manufacturers on a common standard recording format, which allowed cassettes recorded on one manufacturer's machine to play on another's, made a consumer market possible; and the first consumer videocassette recorder, which used the U-matic format, was introduced by Sony in 1971.

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 ...

Linear Video Editing
Linear video editing is a video editing post-production process of selecting, arranging, and modifying images and sound in a predetermined, ordered sequence. Regardless of whether it was captured by a video camera, tapeless camcorder, or recorded in a television studio on a video tape recorder (VTR) the content must be accessed sequentially. For the most part, video editing software has replaced linear editing. In the past, film editing was done in a linear fashion, where film reels were literally cut into long strips divided by takes and scenes and then glued or taped back together to create a logical sequence of film. Linear video editing is more time-consuming, and highly specialized, and tedious work. Still, it is relevant today because of these reasons: * The method is simple and inexpensive. * Mandatory for some jobs: for example, if only two sections of video clips are to be joined together in sequence, it is often the quickest and easiest way. * If video editors learn linea ...

Film Editing
Film editing is both a creative and a technical part of the post-production process of filmmaking. The term is derived from the traditional process of working with film stock, film which increasingly involves the use Digital cinema, of digital technology. When putting together some sort of video composition, typically, one would need a collection of shots and footages that vary from one another. The act of adjusting the shots someone has already taken, and turning them into something new is known as film editing. The film editor works with raw footage, selecting Shot (filmmaking), shots and combining them into Sequence (filmmaking), sequences which create a finished Film, motion picture. Film editing is described as an art or skill, the only art that is unique to cinema, separating filmmaking from other art forms that preceded it, although there are close parallels to the editing process in other art forms such as poetry and novel writing. Film editing is an extremely important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-production
Post-production, also known simply as post, 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 traditional first part of the post-production process, non-linear (analog) film editing, has mostly been replaced by digital or video editing software, which operates as a non-linear editing (NLE) system. The advantage of non-linear editing is the ability to edit scenes out of order, thereby making creative changes at will. This flexibility facilitates carefully shaping the film in a thoughtful, meaningful way for emotional effect. Once the production team is satisfied with the picture editing, the editing is said to be ''locked''. At this point the turnover process begins, in which the picture is prepared for lab and color finishing, and the sound is ''spotted'' and turned over to the composer and sound desi ...
