Important Note about 2K: Operational procedures and information for working with 2K
workflows are presented in Appendix C at the back of this manual. 2K workflows are unique
and require the use of KONA's VTR Exchange and Final Cut Pro, in conjunction with the 2K
Crop features of the AJA Control Panel (discussed in Chapter 4-2K Crop Screen). To begin
working with 2K, please read Appendix C.
For more information on 2K and the use of the AJA KONA 3G card, users should download the
AJA whitepapers on this specific topic on our website (www.aja.com).

Workflow Support
For RED
When working with footage produced by the RED One camera, there are many possible
workflows due to the flexibility of the camera and the hi-resolution images it produces.
Outlined in this section are three possible workflows that Final Cut Pro and AJA KONA 3G
users might elect to implement.
Workflow using RED proxy files
RED recordings produce. R3D files as well as proxy files. These proxy files (which are essentially
QuickTime reference movies) are denoted with an underscore and then a letter designation
that denotes their quality, such as A004_C011_080224_H.mov; this file represents a half
resolution proxy of the source 4K file. Half resolution proxy files reside with the source.R3D
files and are at a 2048x1024 frame size in the REDCODE codec. These half resolution 2K files
can be imported into Final Cut Pro if the RED QuickTime codec has been installed on the
system. For the RED QuickTime codec, visit www.red.com/support.
Red Files
Once proxy files are imported into Final Cut Pro, they can be used in a Final Cut Pro timeline. If
the files are added to a new sequence, the sequence settings dialog prompt will appear. Users
should select the “yes” button in the prompt so that the sequence is set appropriately. Since
the proxy file is essentially a QuickTime reference movie based on the source.R3D wavelet
compression file, it requires some processing overhead to playback seamlessly within Final
Cut Pro and out of the KONA 3G video outputs.
For optimum playback results, the timeline RT settings should be switched to:
•
Unlimited RT
•
Playback Video Quality = Dynamic
•
Playback Frame Rate = Full.
