En este junio y julio, alguna novedad en uhd? Que sean nuevas no remasterización de otras.
Saludos
En el caso de Netflix, la propia aplicación de la tele seguramente soportará HDR, pero si, la Nvidia Shield te permitirá ver también Netflix en HDR.Me acabo de hacer con un televisor con HDR y tengo dudas. En casa sólo consumimos Netflix y MKV. Con estos últimos, ¿podré ver HDR con una Shield?
Hola majos.
No se si esto va aquí o en otro hilo...

Yo también tengo un NAS, y desde red mi tele se lo traga todo en hdr. Seguro que te funcionará.Pero yo lo tengo todo en un NAS, tiene que ser por red...
Dolby Vision Workflow
As most people reading this know, mastering in high dynamic range (Dolby Vision in this case) opens up the possibility of working within a significantly expanded contrast range and wider color gamut over Rec.709 standard for traditional HD. Lost in Space was mastered concurrently for both, which required Ferstl to use Dolby’s workflow. And this involves making all corrections for the HDR version and then allowing the Dolby hardware/software to analyze the images to bring them into the Rec.709 space for the colorist to do a standard-def pass.
Ferstl, who worked with two Sony X-300 monitors, one calibrated for Rec.709 and the other for HDR, explains, “Everyone is used to looking at Rec. 709. Most viewers today will see the show in Rec.709 and that’s really what the clients are most concerned with. At some point, if HDR becomes the dominant way people watch television, then that will probably change. But we had to make corrections in HDR and then wait for the analysis to show us what the revised image looked like for standard dynamic range.”
He elaborates that while the Dolby Vision spec allows the brightest whites to read at 4000 nits, he and the filmmakers preferred to limit that to 1000 nits. “If you let highlights go much further than we did,” he says, “some things can become hard to watch. They become so bright that visual fatigue sets in after too long. So we’d sometimes take the brightest portions of the frame and slightly clamp them,” he says of the technique of holding the brightest areas of the frame to levels below the maximum the spec allows.
“Sometimes HDR can be challenging to work with and sometimes it can be amazing,” he allows. Take the vast vistas and snowcapped mountains we first see when the family starts exploring the planet. “You have so much more detail in the snow and an amazing range in the highlights than you could ever display in Rec.709,” he says.
“In HDR, the show conveys the power and majesty of these vast spaces beyond what viewers are used to seeing. There are quite a few sections that lend themselves to HDR,” he continues. But as with all such tools, it’s not always appropriate to the story to use the extremes of that dynamic range. Some highlights in HDR can pull the viewer’s attention to a portion of the frame in a way that simply can’t be replicated in Rec. 709 and, likewise, a bright highlight from a practical or a reflection in HDR can completely overpower an image that tells the story perfectly in standard dynamic range. “The tools can re-map an image mathematically,” Ferstl notes, “but it still requires artists to interpret an image’s meaning and feel from one space to the other.”
That brings up another question: How close do you want the HDR and the Rec.709 to look to each other when they can look very different? Overall, the conclusion of all involved on the series was to constrain the levels in the HDR pass a bit in order to keep the two versions in the same ballpark aesthetically. “The more you let the highlights go in HDR,” he explains, “the harder it is to compress all that information for the 100-nit version. If you look at scenes with the characters in space suits, for example, they have these small lights that are part of their helmets and if you just let those go in HDR, those lights become so distracting that it becomes hard to look at the people’s faces.”
Such decisions were made in the grading theater on a case by case basis. “It’s not like we looked at a waveform monitor and just said, ‘let’s clamp everything above this level,’” he explains, “it was ultimately about the feeling we’d get from each shot.”
Con dolby vision??

Serán full uhd tal cual del disco original
Habrá que verlas jejejeje

Pienso que hasta que una gran base importate de usuarios finales (consumidores) no tengan un televisor HDR, éste seguirá siendo un nicho de frikis. Pero poco a poco se irá imponiendo, porque no es otra moda más, es como la evolución del blanco y negro al color. Es un hecho que sucederá.
