Betacam SP (Superior Performance) was an analogue broadcast video cassette format, introduced in 1986 as a improvement on the original Betacam.
It used metal-formulated tape and offered increased horizontal resolution of 340 lines. Betacam SP became the industry standard for most TV stations and high-end production houses until the late 1990s.
Betacam SP came in two sizes, with the S-size based on the original Betacam shell and intended for use in camcorders, and the new L-size intended for video editing machines. Whereas Betacam was limited to 30 minutes recording time on the S-size cassettes, the L-size Betacam SP cassette allowed for up to 90 minutes.
