From Azine Software:
TitleLab allows to open .srt, .ssa and .sub subtitle files and convert them to QuickTime text tracks or DVD Studio Pro subtitles. It also allows you to change the text, style and timing on each subtitle and has a load of utilities that allow you to synchronize the subtitles to a movie, and allows batch manipulation of subtitle timings.
What's new in this version:
- changing the font in the Preferences now automatically updates the fonts in all open windows
- opening avi and mp4 (possibly others) movies for syncing should work now
- fixed a NilObjectException with the duration transformation
- fileformats are now recognized "intelligently" (ie, not solely through the file extension), since many .sub files actually appear to be .srt files.
- some other minor changes
