Export Subtitles > Timed Text Formats > Apple iTunes Timed Text (.itt)

This export is created according "iTunesTimed Text Package Specification" specification.

The exported .itt files are of great use to add captions videos in the iTunes platform. Before saving the file you may need to make some adjustments:

Apple iTunes Timed Text Export Configuration

Bold	If this one is clicked, then all subtitle will be exported in Bold.
Override Font Color	By clicking this on, you can override the text color with the one selected from the color palette.
Language	Language will be filled automatically if it's been read and recognized from the source file or it can be selected manually from the list.
Export secondary subtitles track as Forced Narratives	Subtitles from the secondary subtitle track will be considered as Forced Narratives and will be exported as a separate file, according to iTunes Package Film Specification: https://help.apple.com/itc/filmspec/#/apdATD1E32-D1E1A1303-D1E32A1126 The option becomes available only if the loaded file contains two subtitle tracks.
Offset Timecode	Allows you to Recut/Offset the subtitles during the export. From the drop-down menu you can choose between the following options: None - doesn't recut or offset the subtitles and they will be exported with their original timing. Manual - allows you manually specify the offset for the recut. Auto - automatically offsets the timing using the first subtitle's In-cue. All timecodes are offset backward with the first subtitle's In-cue rounded down to the closes hour. For example if the first subtitle originally starts at 10:00:32:21 after applying the recut it's start time will become 00:00:32:21. Programme Start TC - automatically subtracts the value of the Programme Start TimeCode metadata parameter if available in the input file. Note that this parameter is supported for EBU STL, EBU-TT, EZT or EZTXML file formats only. Video Start TC - automatically gets video's start time from the input EZT or EZTXML file and uses it to recut/offset the subtitles.
Recut/Offset subtitles	Allows you to Recut/Offset the subtitles during export. This may be required for subtitle projects that do not start from 00:00:00:00, they are offset by an hour or more. Most video players assume the video always plays from 00:00:00:00 which creates synch issues with subtitles that are offset. The Offset Timecode option above adds a few options to automate the process as needed.
Write Offset Timecode in <div> element	Instead of recuting/offsetting the subtitles, Apple's iTunes format allows the offset to be specified in a <div> element inside the iTT file itself. The offset will then be read and interpret by the end-processor.
