If subtitles are consistently early or late by the same amount, a player subtitle-delay control can shift them. Use a recognizable line and make a small measured adjustment. First verify that the subtitles match the actual edition and language of the video. Use a line with a clear spoken start, note whether the text leads or follows it, and compare another scene after the change. If the gap varies substantially, stop adjusting a fixed delay and check for a different edition or timing-rate mismatch.
Keep audio separate
Subtitle delay and audio delay control different tracks. Keep the audio-video relationship unchanged while adjusting only subtitle timing. An audio-delay control moves speech against the picture and can create a new lip-sync error even if the captions then seem closer. Verify the selected subtitle language and edition first, because a translated phrase may not follow the exact word order of the speech. Use the beginning of a recognizable line rather than expecting every individual translated word to appear at its spoken instant.
Watch the sign
Players can label advance and delay differently. Read the player's wording for advance, delay and signed values before making a small adjustment. Some apps use seconds while others display milliseconds, and the sign convention is not universal. Replay the same line after each change rather than stacking rapid guesses. If captions appear too soon, select the documented operation that moves them later; do not assume that a plus sign always describes the same movement across applications.
Reset after the title
A correction for one asset can harm another. Check a later scene to confirm the same correction still works, then note whether the app remembers the value globally or only for that title. A persistent global offset can misalign perfectly good subtitles in the next programme. Restore the recorded original value when appropriate. If an added scene causes a sudden new mismatch, report the edition problem or use the correctly supplied track rather than applying a second increasingly large fixed shift.

An example to work through
Every caption appears two seconds early throughout the same edition, so a constant shift aligns them. Captions consistently appear about a second before the dialogue in several scenes. A documented subtitle delay aligns those scenes while the audio and picture stay untouched, whereas using the audio-delay slider would have changed the previously correct lip-sync relationship.
Questions about this topic
Will this fix a different cut?
Not when scenes or timing differ. A missing or added scene changes the timeline in ways one constant shift cannot repair throughout.
Does it translate captions?
No. The control only moves the supplied cue timing and does not change the language or words.
