Setup Overview
This Chapter discusses the KONA features that are common across all its plug-ins and the
Machina application. Here you’ll find a basic overview of how KONA operates and is
configured, from making source and format selections to capturing, previewing, and playing
back video and audio.
Selection of Primary & Secondary Formats
In KONA’s operation, the Primary Format is that which is written to disk. The Secondary Format
is set to match the format of the input device (if the Primary Format is a conversion) or to
match the format that is set for an output monitor if you’re monitoring a conversion and the
Primary Format is the format on the input device.
Note: The KONA Secondary Format nomenclature places (O) or (I) at the end of the signal
format: (O) indicates the selected secondary format is for output only. (I) indicates the
format selection is that of an input only.
The Secondary Format isn’t used if there are no conversions. In all of the applications
supported by KONA, you can set these formats. In the Adobe applications (Premiere Pro, After
Effects, and Photoshop), the KONA plug-ins provide similar ways of making these choices. In
each application, though their interfaces may differ, these choices are virtually the same. .
The Primary Format menu allows you to select the video format to be used in the current
project. Analog output is always available and performs a conversion, if necessary, based on
the Primary or Secondary Format.
Note: No frame rate interpolation is applied for conversions from one frame rate to another.
