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 analog Betacam, Betacam SP and Digital Betacam, 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 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 identify which format has been inserted.

The cassettes are available in two sizes: S (short or small) and L (long or large). 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 format supplanted the three-quarter-inch U-Matic format, which Sony had introduced in 1971. In addition to improvements in video quality, the Betacam configuration of an integrated professional video camera and recorder led to its rapid adoption by electronic news gathering (ENG) organizations. DigiBeta, the common name for Digital Betacam, went on to become the single most successful professional broadcast digital video tape format in history. However, by 2008, although Betacam remained in use in the field and for archiving, new tapeless digital products had led to a phasing out of Betacam products in television studio environments.
