Chapter 11, Using Matrox Vetura Capture and Vetura Playback
CC track If your clip contains Matrox 4VANC closed captioning,
Vetura Playback will play back the closed captioning along with the
video for output on MXO2, MXO2 Rack, and MXO2 LE. In order
to output closed captioning, the closed caption data must be on
audio track 16. If the closed caption data in your clip was not
assigned to audio track 16 when the file was exported from Final
Cut Pro (see "Settings for exporting Matrox 4VANC closed
captioning" on page 89), you must indicate which audio track
contains the closed caption data. To do so, enable CC track by
clicking the LED, and select the audio track in your .mov file that
contains the Matrox 4VANC closed caption data.
When this option is enabled, Vetura Playback retrieves the closed
caption data from the specified track and re-assigns it to audio track
16. As a result, any audio track that comes after the specified track
will shift down by one track number. The number of available
tracks are limited to the number of audio tracks that are in your clip.
To output closed captioning from MXO2's SDI or analog output,
set the appropriate settings as explained in
caption capture and playback"
¦ Note Any changes that you make to this option in the
Vetura Playback interface will override the closed captioning
settings in the Vetura Playback preferences (see
Vetura Playback preferences"
Mute Audio Playback
Vetura Playback can play back up to 16 channels of audio.
¦ Note If playing back a clip with closed captioning or AFD
data, audio playback must be enabled.
