Timecode Screen Settings
Input
RP-188 Timecode —in RP-188 timecode (SMPTE 12M-2) there can be multiple timecode
values in the data stream. Use this pull-down to select the one you wish to monitor. The
selection will be displayed in the timecode value displayed to the right of the pull-down.
User Bits—for monitoring variable framerate timecode (for example, Varicam), you may wish
to monitor the user bits embedded in the timecode. If you set this checkbox, KONA 3 will
detect and interpret the user bits and display them next to the checkbox.
Output
Use QuickTime Timecode—when checked, this directs KONA to output timecode from the
QuickTime timecode track. When not checked, KONA uses the Output Timecode Offset
value plus the number of frames into the movie.
Note: not all QuickTime applications use or support timecode tracks, so sometimes the
QuickTime timecode is missing or not meaningful.
Output Timecode Offset (entry field and FPS pull-down)—this text entry field allows you to
specify a timecode offset for use with your video editing application that has timecode
offsets that are user-controlled. Use that same value here as the "Output Timecode
Offset" to ensure the timecode is synchronized.
Timecode Burn-in—this pulldown selects whether the timecode value is
"burned-in" on video output from KONA 3. If set to "OFF", timecode
will not be keyed over the video. If set to "timecode", then the
timecode value will be keyed over the output video. This can be useful
for synchronizing, choosing edit points, dailies, and many other
purposes.
Note: SMPTE RP 188/SMPTE 12M-2 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 real time 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.
