You can adjust the timing offset for an external text-based subtitle. You can not change the offset of a subtitle embedded in a video file or image based subtitles.

Tip!: It is not possible to adjust the offset for subtitles that are embedded in/part of the video file itself. Only for text-based external/”sidecar” subtitles. e.g. .srt files.
