SMPTE-TT Image Based Subtitles

Please note that the exported image files will be created with the font and presentation attributes as they are currently specified in the Project Settings and the individual subtitles.

 

Title, Description and Copyright

Title, Description and Copyright are automatically filled with the appropriate values from the file details if the source subtitle file is an .ezt or .eztxml.

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.

No Region

The language identifier tag consists of two parts Language ID + Country ID. For example, if we select "English (United States)" from the drop-down, the corresponding language tag will be: xml:lang="en-US".
For compliance with other applications or equipment, however, only the Language ID may be required. In this case, activating the No Region checkbox will output the following: xml:lang="en".

Recut/Offset

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.

Timing Information

Specifies how the time is expressed in the output file. By specifications the time base should always be Media, i.e ttp:timeBase="media", and the available time expression options are as follows: HH:MM:SS:FF, HH:MM:SS.NN (10 miliseconds), HH:MM:SS.NNN(miliseconds), Frames, Seconds, Miliseconds and Ticks.

Image Format

By specifications image-based subtitles can be saved as either 8bit or 32bit PNG images.

Prefix

The text value in this field together with the subsequent subtitle numbers forms individual image names.

Crop images to actual size

This option specifies that output images should be reduced to the size defined by the area occupied by the subtitle's text only.

XML file name

The name of the XML file, which contains the In- and Out-cues, image placement, subtitled material title and other information, that will be exported along with the PNG image files.

Create .ZIP archive

By activating this option, all output files will automatically compressed into a single .ZIP file that will reduce the export's size.
