The procedure for extracting subtitles using ProMedia Carbon is described in the following steps:

2. Go to the "Advanced" options

3. Click on Target -> Add and the select the video filter(s) to be used depending on whether you are extracting VBI or VANC captions:

CEA-608 (VBI) - Line 21 extraction
Teletext (VBI) - Teletext Data Extraction
CEA-708 (VANC) - Captions Ancillary (436M) to 708

Description : Creates an XML file containing 608-style closed captions

Profile - System\STL exporter from teletext input
Description : Creates an STL file containing teletext closed captions
