--apply-offset-seconds does not seem to function as expected. E.g., I set it to 107, i.e., 1 minute and 47 seconds, and the subtitles begin syncing to 1 minute and 37 seconds.

The video file begins with a review of the last episode, while the subtitle file ignores the dialogue in the review. I noted that the actual dialogue which corresponds to the subtitle file begins at 1 minute and 47 seconds, and therefore thought the --apply-offset-seconds would begin syncing from this point on, but it does not seem to function this way.

Also, this can be fixed easily by using another program to manually offset the subtitles by the correct amount and then running ffsubsync while omitting parameter --apply-offset-seconds. In this case all I did was use an external program to offset the subtitles by +105 seconds instead of +107 (the original subtitle file begins at the ~2 second mark) then run the standard ffsubsync file.avi -i subtitle.srt -o subtitle.s.srt.
