Delaying Audio During Capture
266
To capture media while protecting Dolby E information:
1. In the Main tab of the Audio Project Settings dialog box, Click Keep Dolby E Material Safe,
and select Yes.
2. Select Tools > Capture.
The Capture tool opens.
3. Check to make sure the Dolby E Safe button displays blue.
If the Dolby E Safe button displays yellow, reset the Dolby E Safe settings in the Audio
Project Settings dialog box (see “Selecting Dolby E Safe Settings” on page 264
).
4. Capture your media using the appropriate capture method. For more information, see
“Capturing Media” on page 222.
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 Tools > 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, your Avid editing application 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.
