Frequently Asked Questions

What subtitle formats does this tool support?

The editor works with common subtitle formats like SRT and VTT, which use timestamps to sync text with specific points in a video.

Why are my subtitles out of sync?

Sync issues usually come from a mismatch between the video's frame rate and the subtitle's timing, or timestamps that weren't adjusted after trimming the video. Double-check the start and end times against the actual video.

Is this subtitle editor free to use?

Yes, it's free with no sign-up or usage limits.
