I have a 43' plasma screen I am using to correct and grade for a feature film. I'm a bit confused about Rec 709. What I think I understand is that it is a standard color gamut used across many displays, including my plasma screen. I've gone in to the color settings under display on my computer and found that I can change the display profile of my plasma screen. The display was set to HD-709-A by default it seems. Is this safe or should I choose another option like HDR HDTV Display (Rec 709) - EOTF SMPTE 2084 or HDTV Display (Rec 709) - EOTF Rec. 1886 (Gamma 2.4) OR should I calibrate the display? If so, under what parameters (white point, gamma, etc.)? Another issue I have is that I don't know if I should grade on a Rec 709 display if the film will be largely distributed over streaming services to be viewed on home computers. Or if I should make two separate grades, one that is sRGB friendly and the other Rec 709. Any advice on this matter is welcome and much appreciated! Thanks, Nick
Canon's 30-Inch 10-Bit IPS LCD Display Features a 16:10 Aspect Ratio, 4096 x 2560 Resolution Full RGB-Array Scanning, and a Backlit Panel to Deliver Precision Color and DCI Standards Compatibility MELVILLE, N.Y., November 6, 2013 – As motion picture, television and commercial production continues to transition to ever-higher resolution digital video and CGI (computer graphic imaging) formats, color-grading and postproduction professionals increasingly rely on reference displays with exceptional detail, color and gradation accuracy. Developed in response to this trend is the new DP-V3010 4K Reference Display from Canon U.S.A., Inc., a leader in digital imaging solutions. The Canon DP-V3010 4K Reference Display measures 30 inches wide diagonally by 7.4 inches deep to help minimize space requirements and provides a 2000:1 DCI-compliant contrast ratio, uniform brightness, very wide viewing angles in all four directions, internal color calibration and additional advanced features. Designed for use in color-grading, digital intermediate (DI), CGI/animation/visual effects (VFX), and editing/finishing suites, as well as digital imaging technician (DIT) workstations on production stages and on-location "video villages," the Canon DP-V3010 4K Reference Display provides full-screen 4096 x 2560 resolution with extremely high levels of color accuracy and fidelity. "We are proud to continue the Canon tradition of providing our customers with complete solution technologies, providing them the option to work within a Canon ecosystem from input through output, and maintain the quality and reliability of our brand," noted Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A. "These displays are the result of the enthusiastic response we received to the Canon Cinema EOS System of cameras and lenses, and we look forward to continuing to demonstrate our commitment to these markets with outstanding technology, quality and reliability to help creative professionals deliver and tell the stories as they envision them." The DP-V3010 4K Reference Display features a 16:10 aspect ratio for the display of video signal information essential to VFX creation. With a tightly packed "pixel pitch" of 157.5æm, the Canon DP-V3010 4K Display provides high-accuracy tonal gradations between darkest and brightest areas, with 1024 shades in each color channel. The technology enabling such performance is a new and proprietary display engine developed by Canon that helps maximize color accuracy and brightness uniformity. The actual panel employed by the DP-V3010 4K Display is an IPS (in-plane switching) LCD with full array RGB LED scanning backlight technology that delivers excellent color accuracy, and crisp video imagery without the perception of motion blurring between frames. By featuring an IPS LCD panel with polarizing and filtering film layers to prevent changes in color and contrast, the DP-V3010 4K Reference Display enables image viewing within a wide viewing angle, top to bottom and left to right. Industry Compatibility The Canon DP-V3010 4K Reference Display is compatible with the five major color gamut standards - SMPTE-C, EBU, ITU-R BT.709, DCI, and AdobeRGB - as well as conforming to DCI standards for 4K display. These DCI standards include a 2000:1 contrast ratio, which the DP-V3010 4K Reference Display evidences in its faithful reproduction of detail in the shadows and accurate highlights. This high contrast accuracy is essential for critical assessment and mastering of high dynamic range cinematic imagery. Also supported by the Canon DP-V3010 4K Reference Display is the ASC CDL (American Society of Cinematographers Color Decision List) format. The display controller provided with the DP-V3010 4K Display includes a dedicated CDL button. Color settings made at the shooting location can be stored on a USB flash drive and imported into the user's color-grading system, which can then relay color correction parameters directly to the DP-V3010 4K Display in the ASC CDL format using slope, offset, power, and saturation parameter adjustments to the overall RGB image and/or separately to the individual R, G, and B channels. The importation of LUT (Look Up Table) data created by third-party color-grading systems is also supported by the DP-V3010 4K Reference Display. The Display allows both 1D and 3D LUTs to be easily imported by operating the menus of the unit itself. This enables accurate color matching between displays and the ability to import customized "looks" created in third-party applications. In this way, the unique colors and gradations intended by producers can be easily reproduced. Ready to support the wide dynamic range of Canon Log gamma video data recorded by the popular Canon EOS C500 and EOS C300 Cinema cameras, the Canon DP-V3010 4K Reference Display also comes pre-installed with the Cinema EOS Canon Log viewing LUT allowing those cameras to be integrated with the DP-V3010 4K Display for linear conversion and display in real time. Furthermore, using 1D/3D-LUT data, the display will be able to provide support for ACESproxy output from Canon's EOS C500 digital cinema camera. A wide variety of the full HD video production format resolutions, typically used for TV dramas, commercials and other TV content, can also easily be displayed by the new Canon DP-V3010 4K Reference Display. To accommodate HD formats, the DP-V3010 Display offers upscaling modes offering smooth and accurate rendering up to 4K resolution of DCI 4K (in up to 12 bit 4:4:4 color), 2K, 1080p, 1080i and 720p. Inputs include 3G-SDI, HD-SDI and DisplayPort connectors for compatibility within many different production, post and VFX workflow environments. Calibration and Convenience Each Canon DP-V3010 4K Reference Display undergoes high-precision calibration before shipment to help ensure high color uniformity between all units. Color accuracy is further improved by the Canon DP-V3010 4K Display's control system, which continuously monitors internal conditions of the display which might affect color, uniformity and performance accuracy, like heat or aging of internal components and make corrections to help ensure long-term image stability and exceptional color consistency. External calibration of the Canon DP-V3010 4K Reference Display can be performed without the need for a dedicated PC application through the use of a third-party spectroradiometer. Use of such an external sensor allows users of the DP-V3010 Display to maintain factory calibration settings as well as help adjustment for specific display applications or account for variations in ambient lighting. The DP-V3010 Display features an easy-to-navigate on-screen display that can be controlled using the included display controller. Built-in carrying handles allow the display to be easily transported and positioned on top of a desk or a counter, or attached to a VESA-compliant bracket for easy wall or rack mounting. The accompanying display controller is designed to be used as both a desktop control device or to be rack-mounted for easy integration into suites, control rooms or mobile vehicle applications, such as HD sports production trucks. Markers, time code display and test patterns are provided within the Canon DP-V3010 4K Reference Display. A variety of markers (aspect, safety zone, grid, and center) and test patterns (pluge, grayscale [20%], white, five-step, ramp, color bars, and black) are also built into the DP-V3010 Display. The Canon DP-V3010 4K Reference Display is scheduled to be available in the first quarter of 2014 for a suggested list price of $40,000.
