Chapter 9, Using Matrox MXO2 with Supported Programs
Specifying settings for Matrox 4VANC AFD
¦NoteMatrox MXO2 Mini does not support AFD.
MXO2 lets you capture the AFD (active format description) data stored in your
video’s VANC, along with your video, and restore the AFD data during playback,
using the Matrox 4VANC tool (see “Matrox 4VANC AFD capture and playback”
on page 70). This section details the settings for capturing and playing back
Matrox 4VANC AFD using Final Cut Pro. You can also use Final Cut Pro to
export a clip with Matrox 4VANC AFD to a file for playback using Final Cut Pro
or Matrox Vetura Playback (see Chapter 11, “Using Matrox Vetura Capture and
Vetura Playback”). For more information about any of the features mentioned in
this section, see your Final Cut Pro documentation.
Settings for capturing Matrox 4VANC AFD
When capturing using MXO2’s SDI input, MXO2 uses audio track 15 to preserve
the AFD data from your video’s VANC (vertical ancillary data space). Prior to
capturing, you must enable track 15 in Final Cut Pro as follows:
1 Open Final Cut Pro, and load an MXO2 Easy Setup (see “Loading a Matrox
MXO2 Easy Setup” on page 85).
2 Choose File > Log and Capture.
3 In the Log and Capture window, click the Clip Settings tab.
4 In the audio area of the Clip Settings tab, enable track 15.
¦NoteSee also “Ensuring frame-accurate capture and edit-to-tape” on page 92
for general capture settings for Final Cut Pro.

MXO2 Easy Setup” on page 85).
