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.

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.
