Srt to DCP subtitles converter

Adding subtitles to a DCP

SrtToCPSubs script creates supplemental package (VF) for original DCP with added subtitles. Currently it is available for download only for Windows. Contact me via email at the bottom of the page if you need Linux or command line version.

It can output subtitles in Interop and SMPTE format, although SMPTE format can be currently selected only on Windows. It has support for multiple reels and automatically adds empty subtitles at the start and beginning in a case of SMPTE subtitles. Input subtitles must be in a UTF-8 encoded SubRip (.srt) format. Output is a SMPTE mxf file or Interop xml file alongside with CPL, PKL, ASSETMAP and VOLINDEX files.
It can read SubRip format with following tags: <b>-bold, <i>-italic, <u>-underlined and <font color= > -font color.

Example of input SubRip subtitles:

1
00:00:12,000 --> 00:00:15,123
This is the first subtitle.

2
00:00:17,000 --> 00:00:21,000
Another subtitle demonstrating tags:
<b>bold</b>, <i>italic</i>, <u>underlined.</u>
<font color="#ff0000">Red text.</font>

 -c "D:\DCP\OV\original_cpl.xml" -o "D:\DCP\VF\\"

You can start the script with -h switch to get a list of all options.
If paths contain spaces, they should be quoted. In that case the backward slash at the end needs to be doubled. You can also use forward slash for path separator. Make sure that created files and folders have appropriate permissions!
