Netflix has completed a worldwide technology upgrade that improves video quality for Premium subscribers viewing 4K HDR titles. The move is being hailed as welcome news in the wake of a price hike to $22.99 from $19.99 for U.S. Premium customers. Netflix used the “dynamic optimization” video encoding method to implement an HDR variant of the company’s VMAF (Video Multimethod Assessment Fusion) quality metric. The new HDR-VMAF is the result of a collaboration between Netflix and Dolby Laboratories that employs “subjective tests with 4K HDR content using high-end OLED panels,” according to Netflix.

Netflix has the largest global audience of any paid streaming service and produces the most original content, optimum position to recommend camera specs and photographic best practices. Netflix requires that at least 90 percent of a program’s content be captured using hardware from its “approved camera list,” which currently includes 51 models from seven manufacturers. There are some exceptions, mainly for documentaries. But the care the company takes in vetting the list — with input from creatives, camera manufacturers and global experts — makes the five-year-old tradition respected guidance for video professionals. Continue reading Netflix-Approved Camera List Has Expanded to 51 Models

Netflix has updated details for approved camera systems as part of its content delivery requirements. “While capturing at a higher resolution is certainly important to image quality, we know it’s not everything,” Netflix camera systems specialist Kris Prygrocki shared, emphasizing that other attributes include dynamic range, color accuracy, noise performance, sensor readout speed, compression, chrome subsampling and bit depth. Other considerations are post-production software support for the recorded file format, proper color management and metadata options, Prygrocki said. Netflix has had camera standards since 2019.

At Baylor University’s Research and Innovation Collaborative (BRIC), Baylor film and digital media professors Corey Carbonara and Michael Korpi and senior research scientist Gary Mandle introduced 6P Color, the fruits of three years of research into exploring the creation of a wider color gamut image. The daylong virtual and in-person event was also the flagship launch of SMPTE+, the organization’s new channel for content and networking, introduced by SMPTE president Hans Hoffman and executive director Barbara Lange. “Expanding the Color Universe: The Next Frontier in Imaging” was the inaugural event in the new SMPTE+ Series. Continue reading Baylor Launches 6P Color Imaging System at SMPTE+ Event

TMS Consulting president Jim DeFilippis, who co-chaired the 6P Color program with Baylor University senior research scientist Gary Mandle as part of the SMPTE+ Series, moderated a discussion about the limits of the RGB color system. XStream member Gary Feather focused on display technology, noting that manufacturers have solved brightness and resolution issues for displays, but not color gamut. “It’s complex,” he said. “But color gamut has headroom to expand” to offer a better toolset for storytelling. “Let’s take that step to move beyond the [RGB] triangle,” he urged.

Nvidia unveiled the first big-screen TVs designed for gamers this week at CES. The company’s “Big Format Gaming Displays” (BFGDs) are 65-inch, 4K screens that tout impressive features such as HDR, low latency, 120Hz refresh rates, full-array backlighting, full DCI-P3 color gamut support, and Nvidia’s G-SYNC technology for smooth game performance (it minimizes screen tearing). “Nvidia is partnering with Asus, Acer and HP to build these displays,” reports Engadget. “With their built-in Shield support, they’ll do everything Nvidia’s set-top box can, and they’ll also come with the company’s remote and gaming controller.” Continue reading Nvidia Introduces Big Format Gaming Displays to Las Vegas

University of Central Florida researchers have developed a technology that could triple resolution for TVs, smartphones and other devices. On today’s video screens, color is produced by red, green and blue subpixels for each of the many thousands of pixels. UCF’s NanoScience Technology Center has discovered a way to, instead, tune each subpixel through differing electrical voltages, enabling them to turn a red subpixel blue, for example. That means subpixels are no longer necessary to display full RGB color. Continue reading Breakthrough Could Triple Resolution for TVs, Smartphones

At the HPA Tech Retreat in Indian Wells, Walt Disney Studios executive/HPA founder Leon Silverman opened the discussion with a look at PLF (premium large format) cinemas. “We have unprecedented levels of quality and immersiveness today,” he said. With the new technologies in resolution, color gamut, dynamic range and brightness, however, comes more work in post production houses. “For the people in the [post production] ecosystem, there’s now an exploding variety of color versions,” he said. The panel also addressed trends in theatrical distribution, exhibition, virtual reality and more.

A Power Session at this week’s HPA Tech Retreat, organized by Disney post production executive Annie Chang, focused on every nook and cranny of high dynamic range and its application in production, post and even displays. The topic is of such interest to Hollywood engineers and technologists that it drew many of the industry’s top experts to speak on their experiences. The Power Session got a start with a short but important HDR primer presented by OneRiver Media owner Marco Solorio, who defined what HDR is and is not. Continue reading HPA Tech Retreat: Production Experts Talk High Dynamic Range

A conversation during CES about the future of 4K UHD TV quickly settled on a single point: 4K without HDR is not a winning proposition. “4K married with HDR will be adopted a lot faster than just plain 4K,” said Technicolor executive Mark Turner. “4K is a binary function: you either have 4K or you’re at 1080p. 4K hasn’t really fired passions in the creative community. HDR does, because then you have a wider color palette and have more detail in the shadows and more highlights.” But both 4K and HDR present challenges.

Philips has joined Panasonic and Samsung in announcing a 4K UHD Blu-ray player with support for high dynamic range. The BDP7501 offers upscaling for non-4K content and includes HDMI, Wi-Fi and Ethernet for connectivity. It also includes built-in support for HEVC and VP9 codecs, which should make it ideal for streaming 4K content from services such as Netflix and YouTube. What may set it apart from early competition, however, is its unique compact design, more akin to a set-top box than a standard disc player. The BDP7501 is expected to ship this spring for under $400. Continue reading CES: Philips is Third Manufacturer to Unveil 4K Blu-ray Player
