About High Dynamic Range and Wide Color Gamut
High Dynamic Range (HDR) and Wide Color Gamut (WCG) are relatively new
ways to present video programming that gives brighter highlights, more
detailed shadows, and additional colors with smoother gradients and increased
saturation. HDR and WCG are display oriented features, dependent on the
capabilities of the device presenting the video material.
When HDR Mode is On, the selected HDR metadata is added to the Ki Pro Ultra's
ProRes recordings, overwriting any HDR metadata that may already be present on
the incoming signal.
The HDR related parameter menus do NOT affect the Ki Pro Ultra's HDMI output
signal, or the output signals on the Ki Pro Ultra's SDI BNC connectors (including
Monitor BNC). No info frame data is included on any of those outputs.
HDR parameter settings do not change any actual video image data. These
settings are only used to add HDR identifying information (metadata) to the
signal. HDR capable HDMI displays use this information to identify and properly
process the signal to match the display's capabilities, optimizing the HDR video
shown on that specific HDMI device. The HDR information is placed in an HDMI
Dynamic Range and Mastering Infoframe and contains the static metadata
descriptors as defined in CTA-861.3 and HDMI v2.0a.
NOTE: The built-in Ki Pro Ultra front panel monitor supports Standard Dynamic Range.
To successfully use the Ki Pro Ultra HDR menus you will need to know the HDR
information associated with that specific video material:
• HDR Mode
• Color Gamut
You then select the HDR operating mode and adjust the associated HDR menu
parameters to match the information to be included in the HDMI Infoframe.
1.69 HDR Mode
The HDR Mode menu is used to indicate a High Dynamic Range (HDR) mode and
gamma curve.
Off (default)
HDR-10 (SD 2084/PQ)
HLG (Hybrid Log Gamma)
Trad Gamma SDR
Trad Gamma HDR
NOTE: When enabled, the associated HDR menus listed below become available.
1.70 HDR Color Gamut and White Point
Identifies the video color gamut and white point. Color gamut defines the
locations for the three vertices of the color primaries, as well as the white point
within the x-y plane of the CIE 1931 color space and, for HDR, the SMPTE ST 2086
color volume.
DCI-P3 D65 (default)
BT.2020
Ki Pro Ultra File Based Recorder/Player v3.3r1
HDR menu settings or incoming HDMI metadata will not change the Ki Pro Ultra's
built-in monitor display characteristics.
