Chapter 9, Using Matrox MXO2 with Supported Programs
$ To preserve the integrity of Matrox 4VANC AFD or closed caption data
for playback (see “Defining your playback settings” on page 116), 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.
3 MXO2 lets you map any audio track in Avid Media Composer/Symphony to
any MXO2 audio output. For information on how to enable and configure
audio mapping in MXO2, see “Specifying your audio output settings” on
page 64.
¦NoteFor surround sound HDMI audio output, the Enable audio mapping
option in the
Audio Output pane of the Matrox Utilities preferences window
must be disabled.
Exporting your sequence to tape
You can record your sequence onto tape using device control or manually as
explained in your Avid documentation. Before exporting to tape, set your desired
playback settings as explained in “Defining your playback settings” on page 116.
For a list of the supported video output formats, see Appendix D, “Matrox
MXO2 Supported Output Formats.”
To export to tape without device control, simply play back your sequence and
record the output from any of the available outputs on your MXO2 system.
If your recorder supports RS-422 device control, you can connect the RS-422
connector on Matrox MXO2, MXO2 Rack, or MXO2 LE to the RS-422 serial
control port on your recorder (see “MXO2 RS-422 serial connection” on page 19,
“MXO2 Rack RS-422 serial connection” on page 30, or “MXO2 LE RS-422
serial connection” on page 39). On Matrox MXO2 Mini, you must use a suitable
adapter to connect the serial device control port on your source device or recorder
to your computer. For a list of supported device control adapters, see the Matrox
MXO2 Support section of our website at www.matrox.com/video/support.
¦NoteWhen using an analog RS-422 device on MXO2, MXO2 Rack, or
MXO2 LE, you must genlock to an external broadcast-quality analog sync
source. If you’re using an SDI RS-422 device and you don’t have an external
broadcast-quality analog sync source, you can set your genlock source to the
MXO2 internal reference and configure the setting on your deck to genlock to the
SDI video input. For details on how to set your genlock source, see “Specifying
your genlock settings” on page 56.
To record the output from your MXO2 system using device control with the
Digital Cut tool, make sure that the Output Mode is set to Real-Time. Also,
when configuring your deck in the
Channel window, make sure that Direct is
selected from the
Channel Type list, and Matrox RS-422 is selected from the
Port list.
