Working with Avid Media Composer and Symphony
1 Specify the MXO2 General settings, and if applicable to your Matrox
hardware, specify the
Genlock settings (see Chapter 7, “Configuring Your
MXO2 System).
2 In Avid Media Composer/Symphony, open the project that you want to play
back.
3 When using an MXO2, MXO2 LE, or MXO2 Rack SDI output for playback,
you can choose to play back Matrox 4VANC AFD (active format
description) or closed caption data that is stored as an audio track, and
restore the data to your video's VANC (vertical ancillary data space) on
output. For more information on Matrox 4VANC, see “Matrox 4VANC
capture and playback” on page 68.
¦NoteMatrox 4VANC is not available on Matrox MXO2 Mini.
To play back the Matrox 4VANC AFD and/or closed caption data, in Avid
Media Composer/Symphony, click
Settings in the Project window, and
then double-click
Audio Project. In the Audio Project Settings dialog
box, in the
Output pane, click the Mix Mode Selection button to select
Direct or Direct, surround tracks in SMPTE order, depending on your
version of Avid Media Composer/Symphony. Then assign the audio track
that contains the Matrox 4VANC AFD data to output as audio channel 15,
and/or assign the audio track that contains the Matrox 4VANC closed
caption data to output as audio channel 16. For information on how to
maintain Matrox 4VANC AFD and closed caption data when exporting your
project to a file, see “Specifying settings for exporting Matrox 4VANC AFD
and closed captioning to a file” on page 122.
¦NoteTo preserve the integrity of the AFD and closed caption data for
playback, do not manipulate the audio tracks that contain the AFD and closed
caption data in any way. For example, do not adjust the audio gain or balance,
or add audio effects to the tracks.
4 In Avid Media Composer/Symphony, click Settings in the Project window,
double-click
Video Output to open the Matrox Utilities preferences
window, and specify your Matrox video output settings as described in
“Specifying your video output settings” on page 60. If you’re playing back
Matrox 4VANC AFD and/or closed caption data, you must enable Matrox
4VANC playback in the
Matrox Utilities preferences window as described
in “Matrox 4VANC capture and playback” on page 68.
5 In Avid Media Composer/Symphony, play back your project.
