subfix

SubFix is a small program for manipulating subtitle files.

Currently it can only handle .srt and .sub formats, though others may be supported later on.

Validation

You can validate a subtitle file by providing a filename as subfix's only argument.

subfix movie.srt

Timing

SubFix can adjust the timing of a subtitle file easily. If you want to delay the subtitles 5.4 seconds, set the time shift (ts) flag:

subfix --ts 5.4s movie.srt

If you instead want to hasten the subtitles just add a minus, like -5.4s.

Format

To convert one format to another, say .sub to .srt, it's as simple as:

subfix --outfile movie.srt movie.sub
