• Remember that the Progressive Playback menu parameter needs to be
configured for Progressive for HDMI output.
1.68 HDMI/EDID Override
This parameter determines whether the HDMI Output is auto-negotiated with the
receiving device via EDID (extended display identification data) or via a specified
output type.
These are the options:
• Auto (default) – The HDMI output is negotiated automatically with the
receiving device via EDID
• 8-bit RGB – Configures the HDMI output for 8-bit RGB
• 4K 4:2:0 (High FR)
NOTE: Typically, you will want to simply leave the selection configured for Auto so that
the negotiation between the devices is handled automatically.
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 12G's ProRes recordings, overwriting any HDR metadata that may
already be present on the incoming signal.
The HDR related settings do NOT affect the output signals on the
Ki Pro Ultra 12G's SDI BNC connectors (including Monitor BNC). No info frame data
is included on any of those BNC 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 12G front panel monitor supports Standard Dynamic
Range. HDR menu settings or incoming HDMI metadata will not change the
Ki Pro Ultra 12G's built-in monitor display characteristics.
To successfully use the Ki Pro Ultra 12G HDR menus you will need to know the
HDR information associated with that specific video material:
• HDR Mode
• Color Gamut
• Mastering Display information
• Program Luminance Levels
You then select the HDR operating mode and adjust the associated HDR menu
parameters to match the information to be included in the HDMI output signal.
