Io HD Installation and Operation Manual — Using The AJA Control Panel
User Bits—for monitoring variable frame rate (VFR) timecode (for example,
Varicam), you may wish to monitor the user bits embedded in the timecode. If
you set this checkbox, Io HD will detect and interpret the user bits and display
them next to the checkbox.
Output
Use QuickTime Timecode—when checked, this directs Io HD to output timecode
from the QuickTime timecode track. When not checked, Io HD 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 Final Cut Pro (or any other
application that has timecode offsets that are user-controlled). In FCP, go to
“Timeline Options” and locate the “Starting Timecode” value. Use that same
value here as the “Output Timecode Offset” 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.
Timelapse Tab
Screen
This Tabbed screen is used for the Io HD timelapse feature. To use the timelapse
capability, choose the "Enable Timelapse Capture" checkbox. This functionality is
enabled for all QuickTime capture applications (Final Cut Pro, VTR Xchange, etc.)
Set the "Capture" and "For Interval" parameters as desired. Launch a capture
application like Final Cut Pro, select the desired Easy Setup for the video format
desired. You will not need to change anything within the application; the timelapse
feature will produce QuickTime files with the framerate specified by the Easy Setup
used. The resulting timelapse clip can be used without additional rendering.
