Frequently asked questions

Can I shift all subtitles by 2.5 seconds?

Yes. Enter 2.5 in Shift All Subtitles and apply. Negative shifts are supported if no cue would start before zero.

Does validation fix overlaps automatically?

No. It reports overlaps and invalid ranges so you can review and correct them.

Yes. Parsing, editing, validation and downloads run locally in your browser.
