Playing back Matrox 4VANC closed captioning
During playback, MXO2 retrieves the closed caption data from the Matrox
4VANC audio track that is assigned to audio output 16, and outputs it using
MXO2’s SDI or analog output. To play back Matrox 4VANC closed
captioning:
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 on
your timeline to audio output
15 + 16, and then use the Pan/balance
control
to set the balance completely to the right (channel 16). If there is
another audio track assigned to
15 + 16, you must set the balance for that
audio track completely to the left (channel 15). Audio track 15 can be
used for Matrox 4VANC AFD data (see “Working with Matrox 4VANC
AFD” on page 94).
¦NoteTo preserve the integrity of the closed caption data for playback, do
not manipulate the audio track that contains the closed caption data in any
way. For example, do not adjust the audio gain or add audio effects to the track.
d Specify your playback settings as detailed in “Defining your playback
settings” on page 84.
e Enable playback of Matrox 4VANC closed captioning in the Matrox
Utilities
preferences window (see “Closed caption capture and playback”
on page 70).
f Play back your sequence.
