Improved Equipment Linkage with Cinema EOS Cameras
4K RAW DeBayer Support
You can now perform DeBayer processing of 4K RAW video shot by an EOS C700 or EOS C700 GS PL, and show the results on the DP-V2420 4K Reference Display. Output through a single 3G-SDI cable is possible when the frame rate is below 30P, or through two 3G-SDI cables when the frame rate is at or above 30P.
This eliminates the need for external DeBayer equipment, and reduces complicated wiring schemes of the camera and display, ultimately increasing mobility when shooting on set.
Metadata Linkage Support
When a DP-V2420 4K Reference Display is connected to an EOS C700, EOS C700 GS PL or EOS C300 Mark II, you can now obtain and display the camera's meta information*.
The ability to now see the camera metadata information on the display side, in addition to on the camera viewfinder, allows more than one person to participate in tasks such as preparing the camera at the filming location and checking the camera information during shooting, improving convenience. Camera confirmation can also be confirmed onsite or near site with this function.
*EOS C700 / C700 GS PL: on all output signals
EOS C300 Mark II: on signals other than 3G-SDI RAW (3G-SDI RAW already supported)
Camera Quality Sync
When the DP-V2420 4K Reference Display is connected to an EOS C700, EOS C700 GS PL or EOS C300 Mark II, image quality settings on the camera and display are automatically synced. This feature helps ensure minimal error by syncing camera setting in real time. For example, if the camera picture mode is set to "Cinema EOS System", the display quality switches automatically based on the meta information. Furthermore, by setting “Automatic Adjustment” to “On”, you can select whether to sync other settings such as “Color Temperature”, “Gamma”, or “Color Gamut”.
The information that can be viewed includes color gamut, gamma, ISO, color temperature, F value, resolution, shutter speed, frame rate, anamorphic, camera state (recording vs. playback).
Anamorphic Lens Support
Video taken with an anamorphic lens* to obtain a special visual expression can now be “de-squeezed” and displayed on the DP-V2420 4K Reference in its original aspect ratio. This allows for quality checks to be confirmed without compression – allowing the user to review actual capture during filming.
*A lens with a special oblong rear lens element that compresses wide-screen width video, shrinking it to about half size.
Additional HDR-compatible LUT Preset
For an ARRI camera’s Log C signal and general Log signal in broadcast, the DP-V2420 4K Reference Display is now preset with an HDR-compatible LUT for displaying HDR images captured with an ARRI camera. You can check the quality of the HDR video just by connecting a camera, without the hassle of importing a special LUT.
Additional HDR Functions / Performance Improvements
ITU-R BT.2100 ICtCp Format Support
The ICtCp format was added to the DP-V2420 4K Reference Display’s supported signal formats. ICtCp is a new format from Dolby Corporation aimed at reducing color reproduction errors. By inputting a signal in the new format ICtCp to the display, you can display SMPTE ST 2084(PQ)/Hybrid Log-Gamma video precisely to specification.
Dual-screen Display Function (4K Input Support)
The DP-V2420 4K Reference Display already supports left-right split-screen display for comparing HDR/SDR by conventional 2K/HD video. This firmware update now supports split-screen display function for 4K video inputs.
It is now possible to display normal 4K/2K video input on the left side of the screen, and HDR support functions (peaking, false color, monochrome, display of areas outside of BT.709 color gamut, etc.) on the right side of the screen. It is also possible to display a compressed brightness range on the left side of the screen, and a clipped brightness range on the right side of the screen.
Additional functionality also includes:
- Video can be split in halves during 4K/2K video display to show a different image quality on the left and right sides
- 4K Video can be split on left and right sides, showing different image quality on each side. For example: HDR (left side) vs SDR (right side)
- Improved usability of function to display 2K video on two screens, showing a different image quality on the left screen and right screen
Comparing video by displaying them simultaneously on the left and right gives the user a great advantage when shooting. This function allows the user, to see at a glance, the brightness ranges, exact tones, and differences in brightness - improving efficiency during HDR filming.
False Color Function (HDR Display Support)
In addition to traditional false color feature, you can now display colors on the DP-V2420 4K Reference Display that vary according to the brightness of the SMPTE ST 2084 (PQ) and Hybrid Log-Gamma input signals. In addition, you can check the brightness level more visually since the colored areas are displayed with a gradient.
This function utilizes the specific HDR ranges that are used with SMPTE ST 2084 (PQ) and Hybrid Log-Gamma to make it easier to visualize the exposure state in HDR shooting, for example by displaying the areas in the HDR range or greater in red and the areas in the SDR range in blue. The width of the red portion of the scale changes depending on how the HDR range is set.
Function to Display Area Outside of the BT.709 Color Gamut
Now when “Color gamut: BT.2020” is set on the DP-V2420 4K Reference Display, it is possible to see colors that cannot be reproduced in the BT.709 color gamut by having them appear red. (The other areas are shown in monochrome.) This makes it possible to visually identify colors that cannot be shown when video captured in the BT.2020 and is viewed in BT.709.
HDR-Compatible 4K Waveform Monitor
The waveform monitor on the DP-V2420 4K Reference Display has been enhanced to utilize specific ranges defined by the scale types of ST 2084 (Full), ST 2084 (Limited) and Hybrid Log-Gamma.
Added “SDI Full” Color Range Setting
In addition to Full and Limited color range settings, an SDI Full color range setting has been added to the DP-V2420 4K Reference Display. The SDI Full color range setting has a black level of 4, a white level of 1019 and 10-bit color depth.
