The Video Home System (better known by its abbreviation VHS) is a consumer-level analog recording videotape-based cassette standard.Several improved versions of VHS exist, most notably Super-VHS (S-VHS), an analog video standard with improved video bandwidth. S-VHS improved the luminance resolution to 400 horizontal lines (versus 250 for VHS/Beta and 500 for DVD). The audio-system (both linear and AFM) is the same. S-VHS made little impact on the home market, but gained dominance in the camcorder market due to its superior picture quality. Another variant is VHS-Compact (VHS-C), originally developed for portable VCRs in 1982, but ultimately finding success in palm-sizedcamcorders. The longest tape available for NTSC holds 60 minutes in SP mode and 180 minutes in EP mode. Since VHS-C tapes are based on the same magnetic tape as full size tapes, they can be played back in standard VHS players.
Also called Beta, and referred to as such in the logo, is a consumer-level analog videocassette magnetic tape recording format.
The format is virtually obsolete, though an updated variant of the format, Betacam, is still used by the television industry.
The 8mm video format refers informally to three related videocassette formats for the NTSC and PAL/SECAM television systems. 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.
DV was originally designed for recording onto magnetic tape. Tape is enclosed into videocassette of four different sizes: small, medium, large and
extra-large. All DV cassettes use tape that is ¼ inch (6.35 mm) wide.
Small cassettes, also known as S-size or MiniDV cassettes, had been intended for amateur use, but have become accepted in professional productions as well. MiniDV cassettes are used for recording baseline DV, DVCAM as well as HDV.
This a format for recording of high-definition video on DV cassette 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.
Conceived as an affordable high definition format for digital camcorders, HDV quickly caught on with many amateur and professional videographers due to its low cost, portability, and image quality acceptable for many professional productions.
Betacam SP or BetaSP (SP for "Superior Performance") became the industry standard for most TV stations and high-end production houses until the late 1990s. Despite the format's age Betacam SP remains a common standard for video post-production.
U-matic is an analog recording videocassette format. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various Reel-to-Reel or open-reel formats of the time. Four decades after it was developed, the format is still used for the menial tasks of the T.V. industry, being more highly specialized and suited to the needs of production staff than the domestic VHS, although as time passes it has been replaced at the bottom of the tree of tape-based production formats by Betacam and Betacam SP.
