Io XT/4K v12.4
Figure 25. AJA Control Panel, Timecode Screen
This feature is for Final Cut Pro 7 (or earlier), VTR Exchange, and AJA TV only. When
checked, it directs Io XT/4K to output timecode from the QuickTime timecode track.
This pulldown selects whether the timecode value is displayed in a "burned-in" window
in video output. 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 for all of the
Io XT/4K outputs. This can be useful for synchronizing, choosing edit points, dailies, and
many other purposes.
When QuickTime timecode in disabled, this text entry field allows you to generate a
timecode based on the offset entry. You can select a framerate from the pulldown menu
at the right side of the pane. Use that same value here as the source video to ensure the
timecode is synchronized.
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 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.
After configuring the AJA Control Panel screens, you can then save all your settings as a
snapshot for later recall—called a preset. In this way, you can organize presets for all your
typical tasks, eliminating time-robbing manual reconfiguration each time. To save a
preset, simply go to the Presets screen and click "Save Preset". A dialog will be presented
asking you for a name; enter a meaningful name and click "OK". Thereafter the preset will
be available under the Control Panel "Presets" list.
