Settings for exporting Matrox 4VANC closed captioning
To maintain the Matrox 4VANC closed caption data when exporting a clip to a
file for playback using Final Cut Pro or Matrox Vetura Playback (see Chapter 11,
“Using Matrox Vetura Capture and Vetura Playback”), you must observe the
following criteria:
• If you want to play back the exported file with closed captioning using
Matrox Vetura Playback, assign the audio track that contains the Matrox
4VANC closed caption data on your timeline to audio output 16. To do so,
choose
Sequence > Settings, and on the Audio Outputs pane, enable 16
channels of audio for your sequence by selecting
16 from the Outputs
menu. Set tracks 15 and 16 as
Dual Mono, and then assign the audio track
that contains the Matrox 4VANC closed caption data on your timeline to
audio output 16.
¦NoteTo avoid having to render a part of your sequence when working with
more than eight audio tracks, set the
Real-Time Audio Mixing option to 16
in
Final Cut Pro > User Preferences.
• The audio must be set to
24-bit 48 kHz, and the audio configuration must be
set to
Discrete Channels.
• Use a lossless or uncompressed audio format. Compressed audio formats are
not supported.
¦NoteUse the File > Export > QuickTime Movie export option to set your
