Chapter 9, Using Matrox MXO2 with Supported Programs
°To configure your Matrox device control settings:
1 In Premiere Pro, choose Premiere Pro > Preferences > Device Control.
¦NoteWhen exporting to tape, Matrox uses a preroll of five seconds. This
value is hardcoded and cannot be changed. The
Preroll and Timecode Offset
options available in Premiere Pro are ignored when using Matrox device
control for export to tape (see “Exporting your sequence to tape” on page 103).
2 From the Devices list, select Matrox Device Control.
3 Click Options to display the Matrox Device Control Options panel.
4 From the Port list, select Matrox RS-422 Port. If the list contains more
than one
Matrox RS-422 Port option, which occurs when your system has
more than one serial device control connection, select the option
corresponding to the desired connection.
¦NoteFor MXO2 Mini users, if you’re using a third-party serial adapter to
connect the serial device port on your source device or recorder to your
computer, the adapter must be connected to your computer before starting your
system for it to appear in the
Port list.
5 From the Time Source list, select the time source to be used for controlling
your device:
$ LTC Longitudinal Time Code recorded on a track adjacent to the video.
This type of time code can be read at all tape speeds, except still.
$ VITC Vertical Interval Time Code that is recorded onto the vertical
blanking interval of the video. This type of time code can be read
whenever an image is displayed, but not usually during high-speed
operation.
$ LTC+VITC Select this if you want your device to decide which type of
time code to use in different operational modes (recommended only if
you’re sure that the two types of time code match on your tape).
