Subtitle Types and Properties

To encode your subtitles as Closed Captions you need to first choose Closed Captions for Target Type and then decide if you need to encode them as CEA 608 or CEA 708 compliant captions. Please mind that the content of the Plug-in's configuration dialog will change according to what you've selected here.

NTSC Television Closed Captions (608)

CEA-608 captions are encoded directly in the signal's VBI for NTSC videos only.

The only decision you need to make in this case will be whether the captions will be encoded in Field 1, Channel 1 and 2 respectively, or in Field 2 - Channel 3 and 4.

Closed Captions specific styles like Pop-on, Roll-up and Paint-on should be previously set with the Closed Captions file you are going to use. Otherwise the text will appear as Pop-on captions on the TV screen.

Digital Television Closed Captions (708)

CEA-708 captions fully comply with the CEA-708-D recommendations of Federal Communications Commission (FCC) and are considered for use only in Digital Television. CEA-708 captions will be encoded directly into the MPEG stream.

Considering that they are intended for Digital Television, CEA-708 captions provide additional options to customize their appearance on the screen.
