Exporting Closed Captions

The following closed captions file formats are supported on export: Scenarist Closed Caption Format (SCC) and SMPTE-TT CEA-608 Captions (.xml).

Depending on the type of the captions file you wish to export to, you will be asked to adjust some of the following settings.

Export channel	Depending on your choice for Channel, the prepared subtitle file will be inserted in one of the two data channels used with the Closed Captions.
Export upper case	Will output a file which text contains only UPPER-case letters.
Double control codes	The control characters are duplicated to ensure correct transmission.
Extended charset	Enables the use of characters from the Line 21 extended character list set. If not selected and there are extended characters in the captions you will receive an error message.
Blank between pop-ons	The default value is 2 frames.

Is Bold	Exports all subtitles text as bold.
Script version	Select "CEA-608" to export standard SMPTE-TT or "Crackle ver 1.1" to export subtitles compatible with Crackle specification.
Font size	Vertical and Horizontal width are used to define the text's precise position on the screen. Values of 80% are considered default because they correspond to the CEA-608 requirements for positioning the text in the 32x15 grid. We suggest you using the defaults unless something else is required.
Time Format	When exporting "CEA-608" file, timing in the output will be expressed as Media Time, whilst when exporting "Crackle" compatible, timing will be exported as SMPTE Timecode.
Tunnel 608	By clicking on the Tunnel 608 Data, raw closed captions data will be exported in the <Head> section of the output SMPTE-TT file in order to preserve the original CEA-608 closed captions stream.
Export channel	Depending on your choice for Channel, the prepared subtitle file will be inserted in one of the two data channels used with the Closed Captions.
