Description

Merli1-2.avi.2023-08-27-20-23-48.tar.gz
--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.

Research direction

Reproduce the report using the attached Merli1-2.avi.2023-08-27-20-23-48.tar.gz file, the subtitle input, and --apply-offset-seconds 107; then trace the command entry point and option handling. Done means the synchronization starts at the requested offset rather than approximately 10 seconds earlier, with the behavior verified against this example.
