Timecode Screen
The Timecode Screen selects the timecode stream read for applications that use
it (for example, when the timecode source is set to “Use control panel setting,”
AJA Control Room will read the selected stream). It is also used for monitoring the
RP-188 timecode embedded in the digital data stream.
Options
Source
In RP-188 timecode (SMPTE 12M-2) there can be multiple timecode types in the
data stream. Use this pull-down to select the one you wish to monitor:
• RP188 LTC (Linear timecode)
• RP188 VITC (Vertical Interval timecode)
• LTC Port input
The selection will be displayed in the timecode value to the right of the pull-
down.
User Bits
Select from Raw or VFR. For monitoring a variable framerate (VFR) timecode
(such as Varicam), you may wish to select VFR for User-bits. KONA will detect and
interpret the user-bits and display them next to the checkbox. You will see the
original framerate (30 fps in the figure below) followed by the adjusted frame
padding (two digits reporting discarded and retained frame padding).
