Delaying Audio During Capture
Sometimes the source from which you are capturing provides an audio signal that is one or more
frames ahead of the video. For example, the Panasonic AG-DVX100 DV camcorder always records
audio one frame ahead of the video. Also, a timebase corrector (TBC) or other video processing
device on your input signal might introduce fixed frame delays of video.

If the input signal is not DV when you choose your IN point, the audio that lines up with the IN point
should remain in sync with the captured media. The video is what shifts in the captured media. If the
input signal is a DV signal however, then the audio shifts.
If the audio you are capturing is always at a fixed offset ahead of the video, use the Delay Audio
feature to correct this problem and produce a master clip with correct A/V sync.
To offset your audio:
1. Select File > Input > Tape Capture.
2. Select the number of offset frames from the Delay audio menu.
3. Capture your material.
4. Play the captured media to verify that the audio and video are in sync.
Working in Quick Record Mode
Quick Record mode allows the deck to control the capture of media into Avid editing systems. In
Quick Record mode, Media Composer starts capturing automatically whenever the servo-lock signal
is detected from the deck. When Servo Lock mode is detected (the deck is playing), capturing begins
and continues until play is stopped, at which point it will wait for the next servo-lock signal.

To use Quick Record mode, you must connect a deck that supports servo-lock signals to the system by
using a deck control serial cable and a serial adapter. For information about the cable connection,
see the setup information that came with your system.
If the appropriate conditions for Quick Record are not present, the messages in the following table
might appear. The second column recommends what you can do to be ready for the Quick Record
mode.
Message Cause or Action Required
