Calibration Operations
Overview of Calibration Operations
Color Calibrator performs calibration in conjunction with the “Camera and Display Plugin” Unreal Engine plugin.
For details about the plugin, refer to the Camera and Display Plugin manual.
Calibration operation workflow The basic operation workflow for calibration is shown below.
Calibration Types
Color Calibrator performs calibration to match the display mode (HDR or SDR) of the display and the luminance management operating mode (Mode A or Mode B).
It supports the following four types of calibration according to the combinations of the display mode of the display and the luminance management operating mode.
- HDR & Mode A
- HDR & Mode B
- SDR & Mode A
- SDR & Mode B
Display mode of the display
Select the type of calibration to match the display mode (HDR or SDR) of the display used when shooting.
HDR
When the display mode of the display is HDR, display an HDR image (color chart) and measure the color characteristics of the display and camera.
This mode enables you to calibrate color reproduction characteristics that include HDR high luminance characteristics.
SDR
When the display mode of the display is SDR, display an SDR image (color chart) and measure the color characteristics of the display and camera.
This mode enables you to calibrate SDR color reproduction characteristics.
[Note]
With SDR, calibration performance may not be obtained, depending on the display characteristics of the display.
If calibration performance is not obtained, it is recommended to adjust the display settings of the display or switch to HDR operation.
Luminance management operating mode
Select the type of calibration to match the operating mode (Mode A or Mode B) set using [Sensitivity Simulation] of a Virtual Camera actor of the Camera and Display Plugin.
[Note]
In Mode B operating mode, a lens with T value indicator and RDD18 metadata are required. In Color Calibrator, Mode B can be selected only when importing an X-OCN file or when inputting an SDI output signal that has RDD18 metadata.
The Mode B functionality is in beta. This is an experimental feature, so conduct sufficient testing before operating in Mode B.
Mode A
This is an operating mode where the deviation in optical luminance between an actual display and camera is included in a Virtual Camera actor.
In Mode A, the brightness of the output video from a Virtual Camera actor changes in thesame way as the actual shooting environment, depending on the type of display used in the virtual space.
Mode A calibrates the luminance and color of the output video of a real camera so that it matches the output video of a Virtual Camera actor.
Mode B (Beta)
This is an operating mode where the deviation in optical luminance between an actual display and camera is not included in a Virtual Camera actor.
In Mode B, the brightness of the output video from a Virtual Camera actor does not change, depending on the type of display used in thevirtual space.
Mode B calibrates the luminance and color of the output video of a real camera so that it matches the output video of a Virtual Camera actor.
[Note]
In Mode A, the brightness of the display (inner frustum) does not change when the 3D LUT for calibration is applied.
Use Mode A when not using a Virtual Camera actor in the pre-vis process or when there is no need to calibrate the luminance of a Virtual Camera actor and a real camera.
In Mode B, the deviation in optical brightness between the actual display and the camera is included in the 3D LUT for calibration, so applying the 3D LUT changes the brightness of the actual display (inner frustum).
Basic Operation
Color Calibrator and the On-set Camera component of the Camera and Display Plugin are used for calibration operations.
The calibration procedure will vary depending on the calibration type. Perform the calibration to match the type.
For details about calibration types, see “Calibration Types” (page 9).
For details about calibration when using a system camera (HDC series), see “System Camera Calibration Operation” (page 15).
“HDR & Mode A” Type Calibration Operation
Use the following calibration procedure when the display mode of the display is HDR and the luminance management operating mode is Mode A.
- Set the calibration chart to “W100” in the On-set Camera component.
The W100 chart appears on the display.
For details, see “Displaying Color Charts on the Display” (page 21). - Check the display settings.
The display must be set to the appropriate settings for successful calibration.
Check that the display is configured as follows.
• Color space setting of the display controller matches the color chart.
• W100 chart is displayed at 100 nits emission (check by measuring the display using a spectral radiance meter or other device).
For details, see “Configuring a Display” (page 23). - Check the camera settings.
Check that the camera is configured as follows.
For details, refer to the manual for the camera.
• Input Color Space:
“S-Gamut3.Cine/SLog3” or “S-Gamut3
SLog3”
• Recording Format:
X-OCN video format
• ND Filter:
“Clear”
• White Balance:
“6500K” On cameras that cannot be set to “6500K,” set to the value closest to 6500K.
• Exposure Index:
VENICE 2 8K (CineAltaV 2 8K) / BURANO (CineAltaB): “800EI”
VENICE 2 6K (CineAltaV 2 6K) / VENICE (CineAltaV): “500EI”
For other cameras, set to match the “Base ISO” setting.
• Base ISO:
VENICE 2 8K (CineAltaV 2 8K) / BURANO (CineAltaB): “ISO 800”
VENICE 2 6K (CineAltaV 2 6K) / VENICE (CineAltaV): “ISO 500”
For other cameras, set the Low “Base ISO” setting.
[Notes]
• When an output signal from a BURANO (CineAltaB) is input via SDI connection, set the codec to XAVC.
• There are no restrictions on the “FPS” and “Shutter” settings, but at high shutter speeds, flicker may occur if the display and camera are not synchronized.
• When operating using a display with a color temperature other than 6500K, set “White Balance” to match the color temperature of the display. - Check the camera viewfinder settings.
The camera viewfinder must be set to the appropriate settings for successful calibration.
Check that the viewfinder is configured as follows.
• Zebra function of the viewfinder is enabled.
• Zebra display of the viewfinder is set to zebra 2 (display level of 61%).
• Output video of the viewfinder is set to Log.
For details, see “Configuring Camera Output” (page 25).
[Note]
If the zebra function cannot be used, use a waveform monitor or the [Waveform] window of Color Calibrator. Input the camera output video (Log) to the waveform monitor or Color Calibrator and check that the signal waveform is displayed. - Adjust the exposure by shooting a W100 chart using the camera.
Set the exposure (61%) appropriate for shooting a color chart in S-Log3. Adjust the shutter and iris to set the exposure so that the zebra appears on the W100 chart when viewed in the viewfinder.
The zebra is displayed when the exposure is 61% or higher. When the exposure is set such that the zebra starts to appear, the W100 chart will be captured at 61% exposure.
[Note]
If the zebra function cannot be used, check the camera output signal in a waveform monitor or the [Waveform] window of Color Calibrator, and adjust the shutter and aperture so that the W100 chart luminance level is 61% or 100 nits in nits display mode. - Set the calibration chart to “HDR1” in the On-set Camera component.
The HDR1 chart appears on the display.
For details, see “Displaying Color Charts on the Display” (page 21).
[Note]
Check that the color space setting of the display controller matches the color chart. - Shoot and record the HDR1 chart using the camera.
Shoot the HDR1 chart using the camera and record to a file in X-OCN format.
Observe the following when shooting the color chart.
• Turn off all lighting in the shooting location and do not use any lighting other than the display.
• Check that nothing is displayed in the outer frustum surrounding the chart display area. If anything other than the chart is displayed, it may be reflected onto the chart and affect the accuracy of calibration.
• Place the chart in the center of the display screen, leaving some space around the chart. When shooting, this helps suppress the effects of peripheral light reduction of the lens.
• Make sure that the chart is not in focus. If you are focused on the display surface, moiré may occur.
When an output signal from a camera is input to Color Calibrator via SDI connection
Calibration is performed by direct input of the video captured by the camera, so there is no need to record to a file.
