Swift: Binary subtitle format to DVD

[jacquezzz]

I'm trying to attach binary subtitles, generated by the subtitling application Swift, to a DVD.

Swift's manufacturer Softel sells a seperate inserter application for this purpose, but it is ridiculously expensive ($8000+, seriously!). And since Swift can already export to BMP's, together with an ASCII timecode file, I figured maybe I could work a way around.

I was thinking about writing a script to convert the timecode file to another, more compatible format, (like SST, and convert the BMP's using photoshop droplets if necessary?) so we could burn DVD's using free or at least affordable software.

I've attached some example output generated by Swift (the TC file carries a .CG extension).

Any advice on which subtitle format I should convert to, and perhaps a description of that format, would be greatly appreciated!

Many thanks!!
