Preserving HD Closed Captioning and Ancillary Data
1100
• You can control which types of ancillary data you capture through the Capture Settings tab
in the Media Creation tool or by using Console commands. The data you capture is the same
as the data you output.
• Four data slots are available, and the maximum size of the four data slots combined is 256
bytes, of which 7 bytes per enabled slot is for Avid control data. You might need to disable
some data slots in order to have enough space for the data you need to preserve.
• 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.
• Ancillary data is not supported when crossconvert or downconvert is enabled.
• You cannot playback a D-track in Legacy mode.
