98 Chapter 5 Capturing Source Clips and Connecting Them to the Database
Calibrating the Timecode Offset
Even when your deck and video capture interface are genlocked together, if you are
going to use serial device control instead of FireWire device control to capture, it is still
essential to calibrate the capture offset (found in Final Cut Pro’s Device Control Preset
tab) prior to capture. To use serial device control, you need to make this setting once
per deck, per computer. For more information, see the section on calibrating the
timecode signal in the Final Cut Pro documentation.
Considerations Before Capturing Audio
Before you capture your audio with Final Cut Pro, you need to take into account
the following:
 If you have an audio deck that can adjust the audio speed to sync to your editing frame
rate when necessary, use the audio deck to do this before you capture the audio into
your computer. See “
Determining How to Prepare Source Clips for Editing ” on
page 109 to find out how you might need to adjust your audio speed.
Note: If you don’t have an audio deck, there are other ways you can adjust the audio
after capturing. See “
Making Adjustments to Audio Speed ” on page 123.
 If you will be editing at 24 fps (the same frame rate at which the film was recorded),
capture the audio at the speed at which it was recorded.
 Before capturing an audio clip that you plan to sync to a video clip, make sure your
device-controllable audio deck is genlocked to a video capture interface installed in
your computer. (See the Final Cut Pro documentation for more information about
genlocking your audio deck to a video capture interface.) Also, in Final Cut Pro, select
the “Sync audio capture to video source if present” option in the General tab of the
User Preferences window.
