Adding a voice-over to your sequence
Matrox Axio supports voice-over, which allows you to record audio tracks as
.wav files directly in the
Timeline panel to add commentary to video clips, such
as newsreels and documentaries.
Remarks
• To use Matrox Axio voice-over, you must have an audio input for the
voice-over as well as a valid video input. The video input is required only for
genlock purposes. It’s recommended that you genlock all the devices
connected to your Matrox Axio system to a reliable external genlock source.
For details on selecting your genlock source, see “Specifying your genlock
settings” on page 94.
• Matrox voice-over does not support pulldown. Therefore, this feature is not
supported for a 486p @ 23.98 fps project, or a 1080p @ 23.98 fps project if
your input format is set to 1080i @ 29.97 fps.
• Matrox voice-over supports recording to stereo or mono audio tracks only.
• Because Matrox voice-over uses the Matrox Axio audio output mapping
settings in the
Matrox Playback Settings dialog box, you must not use the
Audio Output Mapping settings in Adobe Premiere Pro’s
Preferences
dialog box to change your audio output mapping settings for the Matrox
ASIO driver.
