Filmmaking
Filmmaking (film production) is the process by which a motion picture is produced. Filmmaking involves a number of complex and discrete stages, starting with an initial story, idea, or commission. It then continues through screenwriting, casting, pre-production, shooting, sound recording, post-production, and screening the finished product before an audience that may result in a film release and an exhibition. Filmmaking occurs in a variety of economic, social, and political contexts around the world. It uses a variety of technologies and cinematic techniques. Although filmmaking originally involved the use of film, most film productions are now digital. Today, filmmaking refers to the process of crafting an audio-visual story commercially for distribution or broadcast. Production stages Film production consists of five major stages: * Development: Ideas for the film are created, rights to existing intellectual properties are purchased, etc., and the screenplay is written ...

Touchscreen
A touchscreen or touch screen is the assembly of both an input ('touch panel') and output ('display') device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is opti ...

Playout
In broadcasting, channel playout is the generation of the source signal of a radio or television channel produced by a broadcaster, coupled with the transmission of this signal for primary distribution or direct-to-audience distribution via any network. Such radio or television distribution networks include terrestrial broadcasting (analogue or digital radio), cable networks, satellites (either for primary distribution intended for cable television headends or for direct reception, DTH / DBS), IPTV, OTT Video, point-to-point transport over managed networks or the public Internet, etc. The television channel playout happens in master control room (MCR) in a playout area, which can be either situated in the central apparatus room or in purposely built playout centres, which can be owned by a broadcaster or run by an independent specialist company that has been contracted to handle the playout for a number of channels from different broadcasters. Some of the larger playout cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Video Effects
Digital video effects (DVEs) are visual effects that provide comprehensive live video image manipulation, in the same form as optical printer effects in film. DVEs differ from standard video switcher effects (often referred to as ''analog effects'') such as wipes or dissolves, in that they deal primarily with resizing, distortion or movement of the image. Modern video switchers often contain internal DVE functionality. Modern DVE devices are incorporated in high-end broadcast video switchers. Early examples of DVE devices found in the broadcast post-production industry include the Ampex Digital Optics (ADO), Quantel DPE-5000, Vital Squeezoom, NEC DVE and Abekas A-51. By the mid-1980s, Grass Valley Group caught up with to the competition with their Kaleidoscope, which integrated ADO-type effects with their widely-used line of broadcast switching gear. DVEs are used by the broadcast television industry in live television production environments like television studios and outside ...

Wipe (transition)
300px, Examples of various wipe transitions In filmmaking, a wipe is a type of film transition where one shot replaces another by travelling from one side of the frame to another or with a special shape. If the wipe proceeds from two opposite edges of the screen toward the center or vice versa, it is known as a barn door wipe (named for its similarity to a pair of doors opening or closing). The following are some specific styles of wipes: * An iris slow is a wipe that takes the shape of a growing or shrinking circle. It has been frequently used in animated short films, such as those in the ''Looney Tunes'' and ''Merrie Melodies'' cartoon series, to signify the end of a story. When used in this manner, the iris wipe may be centered on a certain focal point and may be used as a device for a "parting shot" joke, a fourth wall-breaching wink by a character, or other purposes. Optional graphic (i.e. rips) occasionally overlay it to achieve a certain effect like an iris tearing trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Server
{{refimprove, date=September 2014 A video server is a computer-based device that is dedicated to delivering video. Video servers are used in a number of applications, and often have additional functions and capabilities that address the needs of particular applications. For example, video servers used in security, surveillance and inspection applications typically are designed to capture video from one or more cameras and deliver the video via a computer network. In video production and broadcast applications, a video server may have the ability to record and play recorded video, and to deliver many video streams simultaneously. Video broadcast and production In TV broadcast industries, a server is a device used to store broadcast quality images and allows several users to edit stories using the images they contain simultaneously. The video server can be used in a number of contexts, some of which include: * News: providing short news video clips as part of a news broadcast as ...

HDTV
High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs. Formats HDTV may be transmitted in various formats: * 720p (1280 horizontal pixels × 720 lines): 921,600 pixels * 1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). * 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP). ** Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame When transmitted at two megapixels per frame, HDTV provides about five times a ...

Standard-definition Television
Standard-definition television (SDTV, SD, often shortened to standard definition) is a television system which uses a resolution that is not considered to be either high or enhanced definition. "Standard" refers to it being the prevailing specification for broadcast (and later, cable) television in the mid- to late-20th century, and compatible with legacy analog broadcast systems. The two common SDTV signal types are 576i, with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems, and 480i based on the American NTSC system. Common SDTV refresh rates are 25, 29.97 and 30 frames per second. Both systems use a 4:3 aspect ratio. Standards that support digital SDTV broadcast include DVB, ATSC, and ISDB. The last two were originally developed for HDTV, but are also used for their ability to deliver multiple SD video and audio streams via multiplexing. In North America, digital SDTV is broadcast in the same 4:3 aspect ratio as NTSC si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instant Replay
Instant replay or action replay is a video reproduction of something that recently occurred which was both shot and broadcast live. The video, having already been shown live, is replayed in order for viewers to see again and analyze what had just taken place. Some sports allow officiating calls to be overturned after the review of a play. Instant replay is most commonly used in sports, but is also used in other fields of live TV. While the first near-instant replay system was developed and used in Canada, the first ''instant'' replay was developed and deployed in the United States. Outside of live action sports, instant replay is used to cover large pageants or processions involving major dignitaries (e.g. monarchs, religious leaders such as the Catholic Pope, revolutionary leaders with mass appeal), political debate, legal proceedings (e.g. O.J. Simpson murder case), royal weddings, red carpet events at major award ceremonies (e.g. the Oscars), grandiose opening ceremonies ...

Moving Image Formats
This article discusses moving image capture, transmission and presentation from today's technical and creative points of view; concentrating on aspects of frame rates. Essential parameters The essential parameters of any moving image sequence as a visual presentation are: presence or absence of colour, aspect ratio, resolution and image change rate. Image change rate There are several standard image-change rates (or frame rates) used today: 24 Hz, 25 Hz, 30 Hz, 50 Hz, and 60 Hz. Technical details related to the backward-compatible addition of color to the NTSC signal caused other variants to appear: 24000/1001 Hz, 30000/1001 Hz, and 60000/1001 Hz. The image change rate fundamentally affects how "fluid" the motion it captures will look on the screen. Moving image material, based on this, is sometimes divided into two groups: ''film-based'' material, where the image of the scene is captured by camera 24 times a second (24 Hz), and ...
