Audio Level

Choose between +6 dB (US) monitor level and +0 dB (EBU).

Timecode Input

Select the type of timecode used by the source video machine—RS-422, Embedded SDI
(RP188) or choose to input an External LTC timecode source input via the KONA RS-422 port.

Note: SMPTE RP 188 defines a standard for the transmission of time code and control code in

the ancillary data space of a digital television data stream. Time code information is
transmitted in the ancillary data space as defined in ANSI/SMPTE 291M. Multiple codes
can be transmitted within a single digital video data stream. Other time information, such
as realtime clock, DTTR tape timer information, and other user-defined information, may
also be carried in the ancillary time code packet instead of time code. The actual
information transmitted through the interface is identified by the coding of a distributed
binary bit. Equipment manufacturers can use the meta data for different purposes.

Desktop Display Options

Select one of four modes of desktop display:

Off

Display while idle only (this mode is suggested)

Display during capture only

Display Always

Display to Desktop uses system resources and could affect performance. Choose Capture
Speed, Width, and Height as appropriate for your system capabilities.

Desktop Speed:

Full Speed – Every frame is displayed to desktop during playback

Half Speed – Every other frame is displayed to desktop during playback

Quarter Speed – one out of every four frames is displayed to the desktop

Half Speed and Quarter Speed will reduce the system load that the Display-To-Desktop is
using to draw video to your computer.

Desktop Capture Width and Height:

These selections allow you to reduce the

resolution of the desktop capture display. The captured file will be full-resolution. Only the
displayed image is reduced to save processing resources during capture. The choices
available are:

Full Resolution

Eighth Resolution

Half Resolution

Sixteenth Resolution

Quarter Resolution
