Blackmagic Design further optimizes its digital composer Ultimatte algorithm Ultimatte 12 incluye nuevos algoritmos, ahora con tecnolog a SDI 12G para contenidos UHD, adem s de una colorimetr a innovadora, ofrece un procesamiento de bordes excepcional, una mayor separaci n de colores, una fidelidad crom tica extraordinaria y una mejor eliminaci n del exceso de verde o azul.
Blackmagic Design ha dado a conocer en IBC 2017 el nuevo Ultimatte 12, un compositor digital que resulta ideal para superponer im genes con calidad profesional, a adir elementos de realidad aumentada a cualquier toma y crear escenarios virtuales.
El nuevo Ultimatte 12 no es simplemente un compositor digital, sino un procesador de vanguardia dise ado para la nueva generaci n de artistas gr ficos que permite combinar im genes en tiempo real. Incluye nuevos algoritmos, adem s de una colorimetr a innovadora, y ofrece un procesamiento de bordes excepcional, una mayor separaci n de colores, una fidelidad crom tica extraordinaria y una mejor eliminaci n del exceso de verde o azul.
La avanzada tecnolog a SDI 12G brinda a los usuarios la posibilidad de trabajar con im genes en alta definici n y, a su vez, estar preparados para procesar contenidos UHD. El tratamiento de cada subpixel en particular permite obtener texturas con una calidad sin igual. Adem s, es compatible con una amplia gama de equipos, de manera que es posible conectarlo a todo tipo de c maras.
Ultimatte 12 permite crear composiciones aut nticas y funciona tanto con c maras fijas y fondos est ticos como con escenarios virtuales automatizados. De este modo, es posible presentar informes meteorol gicos, programas deportivos, boletines de noticias y novedades sobre la industria del entretenimiento con superposiciones de calidad cinematogr fica. Adem s, Ultimatte 12 es ideal para producciones televisivas o cinematogr ficas, ya que ofrece a actores y directores la ventaja de poder ver en el estudio de grabaci n los escenarios virtuales que reemplazar n al fondo verde frente al cual se lleva a cabo el rodaje.
Cabe destacar, por otra parte, que el precio razonable del dispositivo (ronda los 10.000 d lares) brinda la posibilidad de adquirir unidades para una mayor cantidad de c maras, a fin de lograr una calidad superior. Por ejemplo, durante las tomas en directo con m ltiples c maras que filman desde diferentes ngulos, los fondos verdes o azules pueden presentar cierta variaci n. Las herramientas de composici n que ofrecen los mezcladores utilizan los mismos par metros para todas las unidades, lo cual compromete la calidad de la imagen y las superposiciones, ya que existe una ligera diferencia en la forma en que cada c mara capta el color verde. Ultimatte 12 permite resolver estos problemas con una tecnolog a extraordinaria y a un precio razonable, de modo que es posible contar con una unidad por c mara y realizar superposiciones con una calidad sin precedentes. Esto resulta ideal tanto en estudios virtuales como durante la transmisi n de boletines de noticias, informes meteorol gicos o programas deportivos.
Realidad aumentada
La realidad aumentada es un concepto que est cobrando gran popularidad. Ahora la persona que est al aire puede interactuar con diversos elementos, tales como gr ficas computarizadas, pantallas y otros objetos de color transl cidos en cualquier tipo de programa televisivo. Con un compositor com n, es pr cticamente imposible a adir este tipo de elementos, y la imagen no luce real, dado que es muy dif cil extraer el fondo verde o azul de un objeto semitransparente sin afectar su cromaticidad original. Sin embargo, Ultimatte 12 cuenta con un revolucionario modo de composici n que permite superponerlos a la imagen de fondo sin ning n tipo de problemas. Esto significa que los colores pueden verse a trav s de dichos objetos, e incluso es posible vislumbrar a una persona que camine detr s de los mismos, por lo cual la composici n final resulta muy veros mil.
Por otra parte, la tecnolog a de Ultimatte 12 brinda la posibilidad de analizar una escena y configurar autom ticamente m s de 100 par metros para lograr composiciones extraordinarias en tan solo un instante. Evidentemente, los usuarios deben comprobar de todas formas que la iluminaci n sea la adecuada y que el balance de blancos en las c maras sea correcto. El dispositivo cuenta con un bot n especial que permite realizar superposiciones r pidamente y con un m nimo esfuerzo, permitiendo a los camar grafos concentrarse en la calidad del programa.
Los extraordinarios algoritmos, la amplitud del espacio crom tico interno y la generaci n autom tica de m scaras hacen posible que Ultimatte 12 procese cada parte de la imagen de manera independiente. Esto equivale a emplear varios compositores simult neamente en una misma superposici n. Es posible ajustar detalles sutiles de los bordes en aquellas zonas donde es m s necesario, por ejemplo, alrededor del cabello, as como atenuar la transici n de un color a otro en los objetos presentes en la escena. El procesamiento matem tico de cada subpixel permite obtener una calidad sin igual, tanto en HD como en UHD.
New features
Asimismo, Ultimatte 12 ofrece nuevas prestaciones para procesar bordes y reflejos, a fin quitar el fondo y atenuar las transiciones entre distintas tonalidades sin afectar otros colores. Los algoritmos optimizados brindan la posibilidad de eliminar el exceso de verde o azul de cualquier elemento, incluso en reas oscuras o a trav s de objetos transparentes. De este modo, el dispositivo permite mantener y reproducir tonalidades con una fidelidad que otros compositores no son capaces de lograr, por ejemplo, un amarillo intenso frente a un fondo verde. A diferencia de otros compositores, Ultimatte 12 ofrece colores intensos, im genes reales y una nitidez sin precedentes.
Cabe se alar que el dispositivo se controla mediante un panel
