What is Betacam SP? Is it Still in Use?

Sony’s Betamax lost out to JVC’s VHS in the home video entertainment format war in the 1980s. This didn’t stop Sony from venturing into another ‘Beta’ format, namely, Betacam SP or Beta SP. SP stands for Superior Quality. Sony introduced this analogue video camera format in 1986.

Before Betacam SP was Betacam which was released in 1982 as the ‘pro version’ of Betamax. Betacam SP is an enhancement of the Betacam format.

The Betacam system was a 1/2-inch tape format (similar to VHS and Betamax) that needed a camcorder, video recorder, and tape. It was targeted at the professional market. It was meant to be an improvement on Sony’s 3/4-inch U-Matic tape format. Betacam tapes came in two sizes – Short (S) and Long (L). Betacam camcorders for consumers could only load the S version. Only broadcast stations with a complete Beta system could support both the S and L versions through recorders meant for editing. Betacam offered a horizontal resolution of three hundred lines. The tape used the same ferric oxide material used for the Betamax format that Sony introduced in 1975.

Betacam SP’s Features

Betacam SP also uses a larger tape that could record up to 90 minutes.

The Betacam SP tape is of the metal type. The metal tape technology prevents dropouts. The alumina-silica particle coating on it is ideal for long-term archival storage.

On top of that, there are specially developed lubricants that extend player/recorder head life. Its controlled surface roughness increases the signal-to-noise ratio for clearer images.

Betacam SP players will play back Betacam tapes. The reverse isn’t true.

Betacam cassettes are available for sale online.

There’s also a 5-minute cleaning cassette for Beta equipment Sony BCT-5CLN.

Resolution

Betacam SP’s resolution was upped to 34O lines. It is a component recording system through which luminance and chrominance signals are recorded separately.

S-VHS and Hi-8 formats offer better color resolution at 400 lines. However, Beta SP is still the pro’s choice because of its low noise, tape durability, and native component color space.

Betacam SP’s signal-to-noise ratio is 51 dB. For S-VHS it is 46 dB.

Luminance bandwidth is at 4.1 MHz.

Audio Support

Betacam SP supports 4 analog audio channels. Two are AFM channels (Channels 3 and 4) recorded with video.

There are two more standard audio channels recorded separately from video (Channel 1 and 2).

Channels 3 and 4 can’t be altered without affecting the video.

Channels 1 and 2 allow for erasing and rerecording without affecting the video.

Timecode

Betacam SP supports VITC timecode.

Betacam SP Players

There are no longer dedicated Betacam SP Players manufactured. If you wish to get hold of a Betacam SP player, you could go for an analog/digital players like the Sony J-10 Compact Betacam SP/SX Player and Sony J-1 Compact Betacam SP/SX Player.

Betacam SP’s Competitor

Betacam was the go-to format for pros. Competition, however, came in the form of MII. It was an extension of the defunct M format introduced by RCA in 1982.

MII was technically similar to Betacam SP, However, it couldn’t compete with Betacam SP and ended up a failed format.

Betacam SP’s Decline

Betacam was a profitable derivative of the failed Betamax format. Sony managed to sell over 450,000 units sold worldwide in 20 years.

In 2001 Sony announced that it is discontinuing the format owing to declining sales. Also couldn’t stand up to the cost-competitiveness of digital systems.

It also fell out of popularity after Digital Betacam was released in 1993 to replace Betacam and Betacam SP.

How to Digitise Glass Plate Negatives | Oxford Archiving

The Preservation of The Curnock Glass Plate Negatives Introduction Our services ( @OxfordDuplicat1 ) are highly recommended in the UK for specialist photographic film scanning. Trusted to our company, we are preparing The Curnock glass plate collection, held at Oxford Brookes University and part of the @MethodistGB collection. Almost all archives possess some type of photographic collection. Many individuals typically think of “photographs” as plastic-based negatives and slides; but these photographic techniques are relatively recent inventions. Prior to the invention of cellulose nitrate film in 1903, photographic emulsions were made on glass supports. These glass supports are typically referred to as glass plate negatives. The term “glass plate negative” refers to two separate formats: the collodion wet plate negative and the gelatin dry plate. Both of these formats consist of a light sensitive emulsion that is fixed to the glass plate base with a binder. Dozens of photog...

Vellum Document Deed Scanning in Oxfordshire

One of our most interesting orders came in today in the form of a vellum property deed dating back nearly 200 years. We were asked to prepare a digital copy so our client could preserve the original. After assessment we decided on which scanner to use and scanned the deed to a high quality Archival TIFF file before applying post production tone and sharpening. The results were stunning and a wonderful image produced. Interesting fact: To ensure you could prove a duplicate copy, some deeds had a defined curved wave cut out at the top. This meant the original's replica could be matched 100% to the original, safeguarding fraud. What is vellum? Vellum is prepared animal skin or "membrane", typically used as a material for writing or printing on, to produce single pages, scrolls, codices or books. The word is derived from the Latin word vitulinum meaning "made from calf". Typically deeds are folded and stored. Alth...
