Frequently Asked Questions

How do I know if subtitles are early or late?

If subtitles appear before the dialogue, they're early (use positive shift to delay). If they appear after, they're late (use negative shift to advance).

What does positive vs negative shift mean?

Positive values (e.g., +2000ms) delay subtitles, making them appear later. Negative values (e.g., -2000ms) advance subtitles, making them appear earlier.

Can I shift only part of the subtitles?

Currently, the shifter adjusts all subtitles equally. For partial adjustments, consider using video editing software.

Will this change the format of my subtitles?

No, the output format remains the same as the input. Only the timestamps are adjusted.
