Definição do conceito
[POR] Betacam SP | Betacam SP (1986-2001) : Possuía uma maior quantidade de linhas de resolução (500 linhas) e fitas revestidas com partículas de metal Alumina-Silica, gerando uma qualidade de imagem superior. | .../... | Betacam é uma família de formatos de videoteipes profissionais de meia polegada (1/2") criada pela Sony em 1982. | Todos os formatos utilizam o mesmo tipo de fita magnética, que é o que define a Betacam, com a mesma largura e forma de fita. Suas distintas variantes o tornam um sistema altamente compatível e com uma ampla evolução. Os videoteipes Betacam têm dois tamanhos diferentes: "S" (do inglês small, pequeno) e "L" (do inglês large, grande). Porém, as câmeras Betacam suportam apenas o tamanho "S", enquanto que os aparelhos de videocassete suportam ambos os formatos. Os cassetes e caixas possuem cores diferentes, dependendo do formato específico em questão. Betacam incorpora uma chave mecânica que permite ao aparelho de videocassete identificar a que sistema pertence a fita inserida nele. | FONTE : Betacam. in: Wikipedia.

[SPA] Betacam SP | Betacam / Betacam SP : El primer formato ´Betacam´ fue lanzado en 1982. Es un sistema analógico de vídeo por componentes, que almacena la luminancia (Y) en una pista y las señales de crominancia (R-Y, B-Y) en otra distinta. La separación de las señales proporciona una calidad suficiente para un entorno de teledifusión con 300 líneas verticales de resolución. | El Betacam original utiliza cintas magnéticas, que son exactamente las mismas que su versión doméstica, el Betamax, creado también por Sony en 1975. Las cintas vírgenes Betacam se pueden usar en magnetoscopios Betamax y viceversa. La diferencia entre ambos formatos consiste en que Betamax graba una señal de vídeo compuesto (al igual que otros formatos como VHS, U-Matic y el formato C de 1 pulgada), mientras que Betacam usa una señal por componentes y una mayor velocidad de paso de cinta, lo que proporciona mejor calidad de audio y vídeo. Una cinta L-750 permite 3 horas de grabación en Betamax y sólo 30 minutos de grabación en Betacam, pero con una calidad muy superior. | El sistema Betacam SP (Betacam Superior performance, Betacam de rendimiento superior) fue creado en 1986, y mejoraba su resolución a 340 líneas verticales y añadía dos pistas de audio AFM, además de las 2 longitudinales ya existentes. Betacam SP se convirtió en el estándar de vídeo para las cadenas de televisión y la producción de gama alta hasta la entrada de los formatos digitales a partir de mediados de los años 90. Aunque los tamaños y duraciones de cinta son iguales, las cintas de Betacam SP usan recubrimiento de metal puro, de menor calidad, por lo que no se puede utilizar el mismo soporte. En la práctica hay una variación en la duración de las cintas en PAL, puesto que las marcas comerciales indican la duración para NTSC. Por cada 5 minutos de cinta se añade uno adicional; así, una cinta Betacam vendida como de 30 minutos, en PAL durará 36 minutos. | Toda la gama Betacam está diseñada para ser compatible entre sí, pero solo con versión anteriores y generalmente en lectura. Esto significa que un equipo Betacam SP podrá leer cintas Betacam, pero no podrá grabar con ellas y Betacam no podrá leer Betacam SP. Según Sony ha ido incorporando formatos con el sistema Betacam, ha ido manteniendo está compatibilidad. Por tanto, existen magnetoscopios MPEG IMX que leen Betacam, Betacam SP, Betacam Digital, Betacam SX y MPEG IMX. Esta es una de las grandes ventajas que han permitido el éxito de la gama Betacam, puesto que no hace necesario repicar/convertir el archivo guardado en versiones antiguas. | Betacam y Betacam SP suele utilizar cintas de color negro o gris. | FUENTE : Betacam. in: WIkipedia.

[ENG] Betacam SP | Betacam SP : In 1986, Betacam SP (commonly referred to as Beta SP) was developed, which increased horizontal resolution to 340 lines. While the quality improvement of the format itself was minor, the improvement to the VTRs was enormous, particularly in quality and features. In addition to the existing cassette a larger cassette (25.3 × 14.4 × 2.5 cm)[3] was introduced with 90 minutes of recording time. Betacam 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 remained a common standard for standard definition video post-production into the 2010s. The recording time is the same as for Betacam, 30 and 90 minutes for S and L, respectively. Tape speed is slightly slower in machines working in the 625/50 format, increasing tape duration by one minute for every five minutes of run time. So, a 90-minute tape will record 108 minutes of video in PAL. | Betacam SP is able to achieve its namesake "Superior Performance" over Betacam in the fact that it uses metal-formulated tape as opposed to Betacam´s ferric oxide tape. Sony designed Betacam SP to be partially forward compatible with standard Betacam, with the capability that Betacam SP tapes recorded on Betacam SP decks can be played in oxide-era Betacam VTRs (such as the BVW-15 and BVW-40 mentioned earlier), but for playback only. Betacam SP-branded tapes cannot be used for recording in consumer Betamax VCRs like oxide Betacam tapes, due to Betacam SP´s metal-formulation tape causing the video heads in a Betamax deck to wear prematurely, which are made of a softer material than the heads in a standard Betacam deck. However, Betacam SP tapes can be used without a problem in ED Beta VCRs, since the ED Beta format uses metal-formulated tape as well. | SOURCE : Betacam. in: Wikipedia.

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 an L-size intended for video editing machines. Whereas Betacam SP was limited to 30 minutes recording time on the S-size cassettes, the L-size Betacam SP cassette allowed for up to 90 minutes. | A digital version, Digital Betacam was launched in 1993, and subsequently, Betacam SX was launched in 1996 as a cheaper digital alternative. | SOURCE : MUSEUM OF OBSOLETE MEDIA.
