If you make a change to the existing setting it will only be saved and used when the Apply
button at the bottom of the Codex screen is clicked.
Clicking the Reset button, located next to the Apply button, restores the factory default
settings.
Note: Similar controls can be found in the KONA plugins for Adobe Premiere Pro CS5 and
Adobe After Effects CS5 rather than in the Codex application.
KONA DVCProHD Support
AJA includes a DVCProHD codec for capture and editing with the KONA card. The KONA
installer includes Adobe Premiere Pro project presets specifically for use with DVCProHD
compressed files. These project presets have raster sizes that match the non-standard
resolutions and pixel aspect ratios of DVCProHD. They are especially useful when the bulk of
the project media will be DVCProHD.
KONA Capture DVCProHD compressed Quicktime files can be captured from HD-SDI or analog sources using
either AJA’s Machina, or Adobe Premiere Pro CS5 (see Capture setup instructions for the
specific application). All normal capture instructions apply except for the following:
• “File Type” must be Quicktime
• “Video Subtype” must be DVCProHD
• “Primary Video Format” should be set to the real HD raster size
For example, if capturing from a 1920x1080 source, that same raster should be selected in the
“Primary Video Format” control in the capture settings. The encoder will automatically scale
the video down to the appropriate DVCProHD resolution. When using KONA DVCProHD
project presets, these settings will already be preset.
Once capture is completed a Quicktime file will exist on the specified hard disk. If capturing in
Adobe Premiere Pro, the Quicktime file will automatically be imported into the current
Premiere project bin.

AJA’s Hardware
Scaling Support Most AJA hardware has built in hardware-based scaling support that allows for DVCProHD
resolution up-sampling and down-sampling to be done in real-time, with very high quality.
This hardware-based scaling is done during capture and during playback or output from the
editing timeline. The KONA LHi and the KONA 3 both have this support built in.
Codec
Requirements The DVCProHD support included with KONA for PC requires the presence of the KONA card,
and works only in the applications using the card. Quicktime files captured with KONA can be
used in other applications, and even on other platforms, but they require the presence of a
third party DVCProHD Quicktime codec like the one included in Final Cut Pro, or the
standalone Quicktime decoder by Calibrated Software
