Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape could with relative ease record and playback audio, visual, and binary computer data.
DV is a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. It includes the recording or cassette formats DV, MiniDV, DVCAM, Digital8, HDV, DVCPro, DVCPro50 and DVCProHD. DV has been used primarily for video recording with camcorders in the amateur and professional sectors.
Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram.
S-VHS (スーパー・ヴィエイチエス), the common initialism for Super VHS, is an improved version of the VHS standard for consumer-level video recording. Victor Company of Japan introduced S-VHS in Japan in April 1987, with their JVC-branded HR-S7000 VCR, and in certain overseas markets soon afterward. By the end of 1987, the first S-VHS VCR models from other competitors included Hitachi VT-2700A, Mitsubishi HS-423UR, Panasonic PV-S4764, RCA VPT-695HF, and Toshiba SV-950. It has been standardized as IEC 60774-3 and IEC 60774-4.
Betamax 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.
Digital8 is a consumer digital recording videocassette for camcorders developed by Sony, and introduced in 1999. It is technically identical to DV cassettes, but uses physical Hi8 tapes instead.
A camcorder is a self-contained portable electronic device with 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 8mm video format refers informally to three related videocassette formats. These are the original Video8 format and its improved successor Hi8, 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.
MicroMV is a proprietary videotape format introduced in October 2001 by Sony. It is the smallest videotape format — 70% smaller than MiniDV or about the size of two US quarter coins; it is also smaller than a Digital8 or DV cassette and slightly smaller than an audio microcassette. It was the first helical scan tape system using MR read head introduced to the market. Each cassette can hold up to 60 minutes of video.
HDV is a format for recording of high-definition video on DV videocassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
VHS-C is the compact variant of the 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. An improved version named S-VHS-C was also developed. S-VHS's main competitor was Video8; however both became obsolete in the marketplace by the digital video formats MiniDV and MiniDVD, which have smaller form factors.
XDCAM is a series of products for digital recording using random access solid-state memory media, introduced by Sony in 2003. Four different product lines – the XDCAM SD, XDCAM HD, XDCAM EX and XDCAM HD422 – differ in types of encoder used, frame size, container type and in recording media.
AVCHD is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders.
Peep Search is feature available on many videocassette recorders and most camcorders, whereby the unit can show you what is on the tape during rewind and fast forward operations. For this feature to work seamlessly, the tape must be fully laced up during rewind and fast-forward operation, which is not usually supported on VHS decks and therefore makes VHS almost the only video tape format where peep search is not usually available.
Sony Corporation produces professional, consumer, and prosumer camcorders such as studio and broadcast, digital cinema cameras, camcorders, pan-tilt-zoom and remote cameras.
The Sony DCR-VX1000 was a DV tape camcorder released by Sony in 1995. A VX1000 was used to film the British hidden camera show Trigger Happy TV. It was also used by many skateboarders in the late 90s and early 2000s and therefore is an important part in the history of skateboarding culture. The VX1000 was based on Sony's earlier VX1 (PAL) and VX3 (NTSC) Hi8 camcorders, which were similarly intended as "prosumer" models, targeted at both high-end consumer and low-end professional users. In the mid-1990s, Sony began to move away from Hi8 tape in favor of the emerging DV format, and as a result the VX3 and VX1 were discontinued in 1995. However, their iconic form factor, with a distinctively-shaped stereo microphone array at the front of the handle, was reused by the VX1000 and numerous later Sony DV and HDV camcorders in the VX, PD, FX and Z lines.
A 3D camcorder can record 3D video.
