Camcorder
A camcorder is a self-contained portable electronic device with video camera, video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens. The earliest camcorders were tape-based, recording analog signals onto videotape cassettes. In 2006, digital recording became the norm, with tape replaced by storage media such as mini-HD, microDVD, internal flash memory and Secure Digital, SD cards. More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures, whereas dedicated camcorders are often equipped with more functions and Electrical connector, interfaces than more common cameras, such as an internal optical zoom lens that is able to operate silently with no throttled speed, whereas ca ...

Panasonic M5
This is a list of Panasonic camcorders. Professional standard definition models (MiniDV) Panasonic AG-DVX100 (2002) Introduced in 2002, AG-DVX100 was Panasonic's first affordable 3CCD digital progressive scan camcorder. Equipped with a 10x Leica Dicomar lens, sensor was a 1/3 inch, 470,000 pixel 3CCD. DVX100 boasts better specs and picture quality than its physically larger predecessors like AG-DVC7 or DVC15. Includes 2 native XLR microphone inputs. Two revisions, namely DVX100A and DVX100B, were introduced in 2004 and 2005, respectively. Panasonic AG-DVC30 (2004) Introduced in 2004, AG-DVC30 was a 3CCD prosumer model. Essentially a step-down version of the renowned DVX100a, it is physically more compact, but uses a smaller (1/4 in.) CCD and lacks the true progressive scan mode. Also, XLR microphone input is not included by default; a 2-channel XLR adapter was offered as additional accessory.

Video8
The 8mm video format refers informally to three related videocassette formats. These are the original Video8 ( analog recording) format and its improved successor Hi8 (analog video and analog audio but with provision for digital audio), as well as a more recent digital recording format known as Digital8. Their user base consisted mainly of amateur camcorder users, although they also saw important use in the professional television production field. In 1982, five companies — Sony, Matsushita, JVC, Hitachi and Philips — created a preliminary draft of the unified format and invited members of the Electronic Industries Association of Japan, the Magnetic Tape Industry Association, the Japan Camera Industry Association and other related associations to participate. As a result, a consortium of 127 companies endorsed 8-mm video format in April 1984. In January 1984, Eastman Kodak announced the new technology in the U.S. In 1985, Sony of Japan introduced the Handycam, one of the ...

Videocassette Recorder
A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette, and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as '' timeshifting''. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings. VCRs declined in popularity during the early 2000s and in July 2016, Funai Electric, the last manufacturer of them ceased production. History Early machines and formats The history of the videocassette recorder follows the history of videotape recording in general. Ampex introduced the quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commerciall ...

Betamovie
Betamovie is the brand name for a range of consumer grade camcorders developed by Sony for the Betamax format. By "camcorder" is understood a single unit comprising a video camera and a video recorder. Betamovie records analog video on a standard Betamax cassette. A range of models was manufactured for the PAL and NTSC formats. The first model, BMC-100P (PAL) and BMC-110 (NTSC) was released in 1983 making it the first commercial consumer grade camcorder. While only standard beta units were available in PAL, several SuperBeta models were produced for the NTSC format. Due to constructional limitations, the Betamovie has no playback function. It is only capable of recording. This limitation, along with the decline of the Betamax format in the late 1980s, caused Sony to abandon the Betamovie line just a few years after its initial release in favor of its newly developed Video8 format. History As far back as the 1960s, cameras were available for the reel-to-reel portable VTRs of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Camera
A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but was gradually supplanted by optical disc, hard disk, and then flash memory. Recorded video is used in television production, and more often surveillance an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VHS-C
VHS-C is the compact VHS videocassette format, introduced by Victor Company of Japan ( JVC) in 1982, and used primarily for consumer-grade compact analog recording camcorders. The format is based on the same video tape as is used in VHS, and can be played back in a standard VHS VCR with an adapter. Though quite inexpensive, the format is largely obsolete even as a consumer standard and has been replaced in the marketplace by digital video formats, which have smaller form factors. The magnetic tape on VHS-C cassettes is wound on one main spool and used a gear wheel which moves the tape forward. It can also be moved by hand. This development hampered the sales of the Betamax system somewhat, because the Betamax cassette geometry prevented a similar development. VHS-C cassette was larger than Video8 cassette, but was compatible with VHS tape recorders, using a special adapter cassette. The adapter contains a standard full-size engagement hub for the VCR's takeup sprocket, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Phone
A camera phone is a mobile phone which is able to capture photographs and often record video using one or more built-in digital cameras. It can also send the resulting image wirelessly and conveniently. The first commercial phone with color camera was the Kyocera Visual Phone VP-210, released in Japan in May 1999. Most camera phones are smaller and simpler than the separate digital cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010 and decline thereafter. The concurrent improvement of smartphone camera technology, and its other multifunctional benefits, have led to it gradually replacing compact point-and-shoot cameras. Most modern smartphones only have a menu choice to start a camera application program and an on-screen button to activate the shutter. Some also have a separate camera button, for quickness and convenience. A few such as the 2009 Samsung i8000 Omnia II have a two-level shutter butt ...

Betacam
Betacam is a family of half-inch professional videocassette products developed by Sony in 1982. In colloquial use, "Betacam" singly is often used to refer to a Betacam camcorder, a Betacam tape, a Betacam video recorder or the format itself. All Betacam variants from (plain) analog recording Betacam to Betacam SP and digital recording Digital Betacam (and additionally, HDCAM and HDCAM SR), use the same shape videocassettes, meaning vaults and other storage facilities do not have to be changed when upgrading to a new format. The cassettes are available in two sizes: S (for Short) and L (for Long). The Betacam camcorder can only load S magnetic tapes, while television studio sized video tape recorders (VTR) designed for video editing can play both S and L tapes. The cassette shell and case for each Betacam cassette is colored differently depending on the format, allowing for easy visual identification. There is also a mechanical key that allows a video tape recorder to identif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betamax
Betamax (also known as Beta, as in its logo) is a consumer-level analog recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975, followed by the US in November of the same year. Betamax is widely considered to be obsolete, having lost the videotape format war which saw its closest rival, VHS, dominate most markets. Despite this, Betamax recorders continued to be manufactured and sold until August 2002, when Sony announced that they were discontinuing production of all remaining Betamax models. Sony continued to sell Betamax cassettes until March 2016. Original version Launch and early models The first Betamax device introduced in the United States was the LV-1901 console, which included a color monitor, and appeared in stores in early November 1975. The cassettes contain videotape in a design similar to that of the earlier, professional , U-matic form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
