I need to sync a subtitle with a video.
By trial and error, I figured out that the subtitle needs a delay of 3 seconds, every 30 seconds. Is there an automated way to do add this delay? I am somewhat familiar with Aegisub and have used it in the past for minor delay corrections - does it have some advanced options to do what I need?
The subtitles are in SubRip Subtitle (SRT) format.
