SubExtractor v1.0.3.1

SubExtractor converts subtitles from DVDs and PGS (Bluray .sup) files into Advanced Substation Alpha (ASS) or SRT text format using a simple OCR.

Extract subs from (non-encrypted, on hard drive) DVDs and convert to Advanced Substation Alpha format. It can also convert sup (PGS) and sub/idx formats to same. Might require DGIndex, VLC, Aegisub.

It's a wizard-style app, allowing you to pick program chains, angles, audio and subtitle tracks from a DVD folder and create mpg, d2v and bin (its own data format similar to sub/idx) files for each. DGIndex is used to help line up the subs to the video since DVD programs often have discontinuities that mess up sync. If you already have the subtitle track in a separate file(s), you can skip ahead and begin at the OCR step of the wizard.

The OCR is basic but accurate: exact pattern matching of the characters for DVDs, with some fuzzy logic added for High Definition subtitles. The starting OCR database is quite large so most DVDs should require manual matching of just a few characters. Some characters like l, I, 1, o must be manually matched for every DVD since they have a lot of false positives.
