Specifying your genlock settings
¦ Note This section does not apply to Matrox MXO2 Mini.
You can select the source to which you want to genlock all devices connected to
your MXO2 system, as well as adjust the timing settings for all video outputs
from MXO2. For examples of how to connect an external sync source to your
system, see
“Typical Matrox MXO2 connections” on page 19 , “Typical Matrox
MXO2 Rack connections” on page 28 , and “Typical Matrox MXO2 LE
connections” on page 37 .
¦ Note These genlock settings are used during playback only. During capture,
MXO2 genlocks to your selected video input source.
° To specify your genlock settings:
1 Click the Settings tab in the Project window, and then double-click Video
Output .
2 In the Matrox Playback Settings dialog box, click the Genlock tab.
3 Under Genlock Source , select one of the following:
$
Internal Genlock to MXO2’s internal reference signal. Select this
option only if you don’t have an external sync generator or other reliable
external video sync source.
$
Black Burst Broadcast Quality Genlock to an external analog sync
source connected to the reference (REF) input on MXO2. This must be a
stable sync source, such as an external sync generator (bi-level black burst
for SD or tri-level sync for HD), or a source VTR that has a built-in TBC.
