FAQ

Helpful answers

What is an SRT file?

SRT (SubRip Subtitle) is the most common subtitle format. It contains numbered entries with timestamps and text that sync with video playback.

How does timing shift work?

Enter a positive or negative millisecond value to shift all subtitle timings forward or backward. This fixes sync issues without editing each entry.

Can I edit individual subtitles?

Yes. Each subtitle entry has an editable text field so you can modify the content directly.
