Ross Video enters the market of capture with a camera specifically designed for production with chroma La nueva Acid dispone de un camino de se al paralelo en la salida del sensor que transfiere nicamente la informaci n de color en una se al 0:4:4.
The Canadian manufacturer Ross Video ha vuelto a dar la campanada en este NAB 2016 al anunciar su entrada en el mercado de la captaci n. Su primer proyecto ha sido bautizado como Acid y se trata de una c mara Full HD pensada principalmente para producciones con chroma-key.
El CEO de la compa a, David Ross, ha comentado que vemos c mo los fabricantes anuncian cada vez m s resoluci n en sus c maras pero, sin embargo, cuando se trata de captar en una pel cula o una ficci n en televisi n escenas grabadas con un set virtual todo parece ser falso. Por eso nos hemos animado a resolver esta cuesti n con una soluci n realmente revolucionaria .
Para desarrollar esta c mara, Ross ha observado muy de cerca c mo se abordan en la actualidad este tipo de producciones que suelen utilizar fondos con un chroma de color.
Tras estas pesquisas, el equipo de desarrollo de Ross ha llegado a la conclusi n de que el problema radicaba en la cantidad de informaci n de color que recog a el sensor.
Las c maras funcionan bajo un patr n 4:2:2, algo que tiene sentido para filmaciones, pero no cuando la variaci n de color precisa ser extremadamente exacta. Por eso hemos desarrollado una c mara Full HD 4:4:4 , ha explicado Ross.
En el n cleo de esta propuesta encontramos un peque o truco que garantiza la integridad de la informaci n de color. La Acid posee un camino de se al paralelo en la salida del sensor que transfiere nicamente la informaci n de color en una se al 0:4:4. Esta se al tiene una salida dedicada en la c mara para mezclar posteriormente el patr n 4:2:2 y conseguir una total exactitud en la se al.

Junto con a Acid, Ross ha anunciado el Keyer Carbonite UltrachromeHR. Concebido como parte del nievo sistema de chroma, el UltrachromeHR cuenta con una entrada adicional para la se al 0:4:4 y realiza procesamiento de mezcla internamente para obtener el mejor resultado posible en t rminos de separaci n de color. Pese a que Ross lo ha concebido como un complemento para la Acid, UltrachromeHR funciona tambi n como un keyer para otras aplicaciones.
La nueva Acid estar disponible en dos modelos ACIDH200-UCHR y ACIDZ50-UCHR. La primera cuenta con tres sensores de 2/3 con 2.6 megap xeles UAIT MOS y un ruido por debajo de 64dB. En el segundo modelo, son tres sensores 2/3 de 1.1 megap xel CCD los encargados de recoger la imagen (60 dB de se al-ruido).
