39 Setup & Configuration — Codex Utility
Codex Utility
When KONA software is installed, a utility application named Codex is put in the AJA directory
(Programs -> AJA -> Codex). This utility allows you to make global adjustments to the YUV/RGB
Matrix in both the QuickTime and AVI Codecs used by third-party applications. (Does NOT apply
to Premiere Pro CS5 and After Effects CS5.)
The Codex utility allows you to adjust the matrices used when YUV–RGB conversions are
performed by applications such as Fusion, and Combustion. These conversions occur during
YUV–RGB encoding/decoding when creating or opening QuickTime and AVI files using the AJA
AVI/QuickTime codecs.
Codex Application Screen
The pulldown menus in this screen are organized by the function being performed. Pulldowns
on the left are for AVI file decompression and compression and those on the right are for
QuickTime decompression and compression.
In each pulldown, the current setting is displayed. When you click on any of the pulldowns, the
choices available for each are all the same:
• 601 SMPTE
• 601 CGR
• 709 SMPTE
• 709 CGR
The 601 matrices govern Standard-definition component digital color scaling matrices and the
709 apply to High-definition color scaling matrices.
