Preserving HD Closed Captioning and Ancillary Data

Data Track Method
The Data Track method stores ancillary data as a separate MXF file. A D (Data) track is added to
your sequence, along with the video and audio track. You can edit clips on the
D track, just as you would any other clip.
When you use the Data Track method, ancillary data preservation is subject to the following
requirements and limitations:
• You can capture and output the MXF media using Avid Nitris DX or Avid Mojo DX
input/output hardware only.
• You can control which types of ancillary data are captured through the Capture Settings tab
in the Media Creation tool. The data you capture is the same as the data you output.
• Four data slots are available, and the maximum size is selectable.
• To view and monitor ancillary data, you must connect an ancillary data capable device to the
output of your Avid hardware.
• You can AMA link to XDCAM and MXF media that store ancillary data. For more
information, see “Ancillary Data and AMA” on page 1096.
• You cannot add an effect to the Data track.
• Ancillary data is not supported when crossconvert or downconvert are enabled.
• You cannot patch a Data track.
• Multicamera (group clips) is not supported with a Data track.
• A Data track is not allowed when you use mixed rate clips.
• You cannot transcode a data clip.
• You must output through the HD-SDI port of your Avid input/output hardware. Ancillary
data is only supported through the HD-SDI input/output of your Avid hardware.
• There is no support for a Data track in the Avid FilmScribe application.
• At this time, the following resolutions/projects are not supported with a data track: RGB,

• Data tracks are supported when you export a sequence to a playback device through the
Transfer > Send to Playback option (exporting a sequence with Data tracks to an Avid
Interplay Transfer environment). For information about Send to Playback with a Data track,
see your Avid Interplay documentation.
• At this time, there is no support to export a sequence with a data track through the
File > Send To template options, for example, ProTools.
