The advantages of using the KONA 3 as an input/output device extend beyond its 2K
HSDL functionality. Not only can users ingest 2K data as simultaneous 2K DPX files
and QuickTime files, edit this information, and then output 2K data, but users can also
elect to ingest 2K data and output simultaneous HD from a crop directly derived from
the 2K media. An SD downconvert of this HD video can also be created
simultaneously, if so desired. For review of 2K data on HD and SD monitors, and for
some mastering scenarios, the KONA 3 card can be used as a very flexible and effective
tool.
Existing 2K data files in the Cineon and DPX file formats can be “wrapped” into 2K
QuickTime Reference Movies via AJA's DPXToQT Translator application so that users
can take advantage of the aforementioned flexibility without writing any new data to
their drives. QuickTime reference movies only point back to the source original DPX
files from which they are derived. The main advantage of this, beyond not writing any
new data to the drives, is that the cumbersome sequence of potentially thousands of
frames can be consolidated non-destructively to a single file.
Furthermore, once media exists as a 2K QuickTime movie, it can be converted back
into sequential DPX files that can be given to facilities using software or hardware, such
as film recorders, that do not accept QuickTime files. This conversion can be
accomplished via the AJA QTToDPX Translator application. This process, it should be
noted, does require writing new data because it may reflect creative changes to the
images that the user desired, such as effects.
Note: The QTToDPX Translator and DPXToQT Translator are both available from
the AJA website in the KONA 3 support area:

AJA Video Systems, Inc. along with other 2K HSDL device manufacturers, has seen the
growing need for a high quality image source, like 2K, in an evolving data-centric
workflow. A 2K source can be used to derive the high quality film, digital cinema, HD
and SD deliverables without compromise outside of a cumbersome leap to 4K. 2K
capable devices, like the AJA KONA 3 card, will help facilities and filmmakers enter a
data-centric workflow that results in a universal mastering environment.
The KONA 3 2K Process—Ingest to Output
The following step-by-step procedure outlines the task of bringing in 2K material from
telecines or other HSDL devices connected to the dual SDI inputs on the KONA 3
card. The 2K ingest process requires the use of the AJA VTR Xchange software and
configuration of the AJA KONA Control Panel.
The procedure for ingest of 2K is as follows:
1. Connect the telecine with HSDL output (or other HSDL output capable device) to the
KONA 3's two SDI inputs. (If you already have 2K DPX or Cineon files on storage
capable of 300MB/sec., you can elect to use the AJA DPXToQT Translator
application to “wrap” the sequential DPX or Cineon files to QuickTime Reference
Movies. If this is the case, skip ahead to step 6 of these instructions.
2. Configure the AJA Kona Control Panel as follows:
A. For the Input tab of the KONA Control Panel, make certain that Dual Link
is selected for Video Input.
