Questions
How do I fix subtitles that drift?
Find two cues, one near the start and one near the end. Enter their cue numbers and the times they should start at. Every cue in between moves onto the same straight line.
What does the frame-rate change do?
It scales every time by the first rate divided by the second. Use it when subtitles were timed for one frame rate, like 23.976, and the video plays at another, like 25.
Is my subtitle file uploaded?
No. The text is read and rewritten in your browser, so the file never leaves your device.
Can it convert SRT to WebVTT?
Yes. Choose WebVTT under Save as. The times then use dots and the file starts with the WEBVTT line.
