Defining your A/V Tools options
6 If you want the VU meters to be displayed each time you configure your
capture settings or start a capture in A/V Tools, select
Show VU meters .
This option is not available if you’re working with 1080i @ 29.97 fps video
and using a 10-bit video processing format. For details on using the VU
meters, see
“Monitoring audio levels for capture” on page 196 .
7 If you experience dropped frames during capture, select Disable audio
preview to disable the audio preview only while you’re capturing material.
8 Under Capture Files , indicate whether you want to capture to stereo or
mono audio files, and select which channels you want to save to separate
.wav files.
$
From the File Type list, select Stereo to save your captured audio to
stereo .wav files, or Mono to save your captured audio to mono .wav files.
$
From the Filename lists, select which stereo pairs or mono channels you
want to save to your .wav files (up to four stereo files or up to eight mono
files depending on the type of audio being captured). Select None for the
particular .wav files you don’t want to be created, or click the D (default)
button for each Filename list if you want to capture only channels 1 and
2. When A/V Tools saves each .wav file, it assigns a .Stereo.wav or
.Mono.wav suffix to the base name you gave for the associated video file.
For example, if you’ve named your video file MyFile.avi , the associated
stereo audio files would be named MyFile.Stereo1.wav ,
MyFile.Stereo2.wav , etc.
¦ Note The channels that you choose to save to the first stereo .wav file or first
two mono .wav files will be embedded in the associated .avi file.
