Apple Final Cut Pro 7 - Manual (Page 215)

7 If you are using a blackburst generator, choose Final Cut Pro > User Preferences, and in
the General tab of the User Preferences window, make sure that “Sync audio capture to
video source if present” is selected.
8 If you’re using Final Cut Pro to control your audio deck, make sure that the device control
switch on the equipment is set to Remote.
For more information, see “Choosing Settings and Preferences.”
9 Once your deck and video capture interface are genlocked together, you still need to
calibrate the timecode capture offset (found in the Device Control Presets tab in the
Audio/Video Settings window) prior to capture.
For more information about calibrating timecode for capture, see “Device Control Settings
and Presets.”
Connecting Remote Device Control
Device control enables communication between your VTR or camcorder and Final Cut Pro,
allowing you to remotely control your video deck for capturing and output. A VTR can
tell Final Cut Pro where a tape is currently positioned, and Final Cut Pro can tell the VTR
to cue the tape to a new position, pause, rewind, fast-forward, and even record during
output. Positional information is conveyed via timecode recorded on the tape. Also,
timecode information is sent via a device control connection. This is critical for logging,
batch capturing, and frame-accurate output to tape.
DV FireWire for Device Control
In addition to video and audio data, DV devices can transfer timecode and device control
via FireWire. This makes connecting DV devices to your computer as simple as connecting
a single FireWire cable. For more information, see
“Confirming Remote Device Control
Between Final Cut Pro and Your DV Device.”
Using RS-422 Serial Remote Device Control
For professional equipment, device control data is transferred between a serial port on
your computer and a 9-pin D-subminiature (D-sub) connector on a professional video or
audio device. Mac computers have two types of serial ports: USB ports and internal modem
ports. With the appropriate adapters, either of these ports can be used to send and receive
device control information via serial RS-422 or RS-232 protocols.
