Chapter 9, Using Matrox MXO2 with Supported Programs
When using MXO2 with Avid Media Composer/Symphony, your source material
is captured to your project’s video format. You can also preview the captured
video using the Matrox MXO2 outputs. When previewing the captured video, the
output video format will match your project’s video format. For a list of the
supported input and capture video formats, see Appendix C, “Matrox MXO2
Supported Input and Capture Formats.”
¦NoteThe SD channel video output setting is not supported on MXO2 during
capture. To preview the captured video,
Main channel must be selected for the
MXO2 outputs in the
Video Output pane of the Matrox Utilities preferences
window (see “Specifying your video output settings” on page 60.
If you want to capture material using RS-422 device control, you can connect the
RS-422 connector on Matrox MXO2, MXO2 Rack, or MXO2 LE to the RS-422
serial device control port on your source device (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.
Remarks
• To capture video on Matrox MXO2, your project’s color space must be set to
YCbCr.
• Matrox MXO2 supports the
Audio tool so that you can monitor and adjust
your audio input levels for capture.
• Capture on Matrox MXO2 is not supported for a 24p NTSC, 24pPAL, or
720p/29.97 project.
°To specify your capture settings:
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 Open Avid Media Composer/Symphony and create a new project (see
“Creating a new Matrox MXO2 project” on page 116). Your source material
will be captured to your project’s video format.
3 In the Capture tool, make sure that Matrox is selected as the Video and
Audio input sources.
4 When using an MXO2, MXO2 LE, or MXO2 Rack SDI input for capture,
you can choose to capture the AFD (active format description) or closed
caption data that is stored in your source video's VANC (vertical ancillary
data space) by using the Matrox 4VANC tool. For more information on
Matrox 4VANC, see “Matrox 4VANC capture and playback” on page 68.
