Frequently asked
How do I know which way to shift?+
Watch the video and pick a moment where someone speaks. If the captions appear too late, use a negative offset (e.g. -1.5 seconds). If they appear too early, use a positive one. Match the lag visually, then download.
What's the smallest shift I can apply?+
You can type any decimal — 0.05s (50 ms), 0.001s, anything. The output preserves millisecond precision in SRT and VTT.
Will negative shifts clip the start?+
Cues that would land before 00:00:00 are clamped to zero. If you have a long lead-in to remove, that's usually what you want.
Does it handle both .srt and .vtt input?+
Yes — paste or upload either. The parser auto-detects WebVTT (header / dot timestamps) vs SubRip (comma timestamps).
What if my drift increases over time?+
A constant offset only fixes constant lag. If subtitles drift further off as the video plays, you have a frame-rate mismatch (e.g. 23.976 vs 25 fps), which needs resampling — not a shift.
