Working with Matrox 4VANC closed captioning
MXO2 lets you capture and play back video with digital closed captioning using
the Matrox 4VANC tool. This section details how to capture and play back
Matrox 4VANC closed captioning using Adobe Premiere Pro. You can also use
Premiere Pro to export a sequence with Matrox 4VANC closed captioning to a
file for playback using Premiere Pro. For more information about any of the
features mentioned in this section, see your Premiere Pro documentation.
¦NoteMatrox MXO2 Mini does not support closed captioning.
Capturing Matrox 4VANC closed captioning
When using MXO2’s SDI input for capture, Matrox 4VANC lets you
preserve the closed caption data from your video’s VANC (vertical ancillary
data space) by capturing the data as an audio track.
If Matrox 4VANC capture is enabled in the
Matrox Utilities preferences
window, Matrox MXO2 uses audio track 16 to preserve the closed caption
data during capture in Premiere Pro. The resulting file is an uncompressed
24-bit 48 kHz audio file that contains the closed caption data. The Matrox
4VANC audio track that contains the closed caption data can then be used in
Premiere Pro to play back closed captioning through MXO2’s SDI or analog
output (see “Playing back Matrox 4VANC closed captioning” on page 97).
Because audio track 16 is used for capturing closed captioning, that channel
will not be available for capturing audio. To capture Matrox 4VANC closed
captioning:
