Chapter 9, Using Matrox MXO2 with Supported Programs
Exporting Matrox 4VANC closed captioning to a file
This section details how to maintain the Matrox 4VANC closed caption data
when exporting your sequence to a file. The exported file can then be used in
Premiere Pro for playback (see “Playing back Matrox 4VANC closed
captioning” on page 97).
a In Premiere Pro, choose File > New > Sequence. In the New
Sequence
dialog:
• In the Tracks pane, select Multichannel from the Master list.
• From the Number of channels list, select 16, and then set the Track
Type
for each track in your sequence to Mono.
• In the Settings pane, under Audio, select 48000 Hz from the Sample
Rate
list.
b Set the remaining settings in the New Sequence dialog, and then click
OK.
c With your project files on the timeline, in the Audio Track Mixer, assign
the audio track that contains the Matrox 4VANC closed caption data to an
audio output pair (for example,
3 + 4), and then use the Pan/balance
control
to set the balance of the Matrox 4VANC track completely to the
left or right. If the selected audio output pair is assigned to another audio
track, set the balance for the other audio track to the other side. For
example, if the Matrox 4VANC closed caption audio track balance is set
to the left, set the balance for the other audio track that is assigned to the
same audio outputs to the right.
d Choose File > Export > Media.
e In the Audio pane, select a lossless or uncompressed Audio Codec.
Compressed audio codecs are not supported for use with Matrox 4VANC.
f Under Basic Audio Settings, select 48000 Hz from the Sample Rate
list.
g From the Channels list, select the number of audio channels to export.
¦NoteMono, 5.1, and Stereo are not supported when exporting
Matrox 4VANC closed caption data.
h From the Sample Size list, select 24 bit.
i Export your sequence to file. If you have an MXO2 product with MAX
technology, see Chapter 10, “Using the Matrox MAX H.264 Codec” for
information on exporting your sequence using the Matrox MAX H.264
codec.
