FREE VIDEO WORKFLOW TOOLS
Subtitle time shifter
Move every cue earlier or later by an exact offset. Preview before downloading.
Free · no sign-up · runs in your browser. Your input is not uploaded or stored by this tool. Up to 1 MiB UTF-8 text / 5,000 plain-text cues.
How to use it
- Open plain SRT or VTT and identify a known line against your video.
- Enter an offset in seconds: positive for later, negative for earlier.
- Preview every changed timestamp and download the new file. Check another line near the end.
What to check
One offset repairs a constant delay, not drift that grows over time. Existing overlaps or out-of-order starts require review first. If any cue would become negative or exceed 24 hours, the whole export stops; no cues disappear.
