Chapter 8, Defining Your Adobe Premiere Pro Settings
¦NoteIf you experience dropped frames when capturing embedded SDI
audio on Axio LE, you can set your audio capture source to
SDI (embedded
audio) - One pair only
. This improves the capture performance by processing
only one audio pair for the capture.
5 Under Capture Format, select the bit-depth for your captured audio files. If
you’re capturing from a DV-1394 device, the
Capture Format will be set to
16-bit.
6 If you don’t want the VU meters to be displayed each time you configure
your Matrox Axio capture settings or open the
Capture panel to start a
capture, clear
Show VU meters. This option is selected by default. For
details on using the VU meters, see “Monitoring audio levels for capture” on
page 103.
7 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. If you’re
capturing an .m2v clip, the
File Type will be set to Stereo.
$ 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 Matrox Axio 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.
Remarks
$ 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. When you
import your .avi file to the
Project panel, the clip’s separate .wav files will
also be imported, and the embedded audio in the .avi file will be ignored.
The clip’s .avi file and first associated .wav file, however, will appear as a
single Movie clip in your project. The embedded audio in the .avi file will
be used only if the .avi file does not have any associated .wav files.
Therefore, if you perform audio post processing on your .avi files, make
sure you delete the associated .wav files so that only the embedded audio
in the .avi files will be used in your project.
$ When performing an audio-only capture, Matrox Axio supports capture of
only one stereo pair. Your first stereo or first two mono channels will be
