# Shift subtitle timing: fix SRT and VTT delay
Cutshed Timing shifter is a free browser tool that runs on this device. Offset or scale SRT and VTT timestamps and download the result.
Shift subtitle timing when an SRT or VTT is early or late. This is the fix for an SRT delay: add an offset, or scale the timestamps, then download the file. Nothing is uploaded. Write the captions on Subtitles , translate them on the subtitle translator , or turn speech into a transcript when you do not need cue times.
## How to use it
- Open an SRT or VTT. The file is read in the browser and is not uploaded.
- Set the offset in seconds. A positive offset makes every cue later. A negative offset makes every cue earlier. A cue that would start before zero starts at zero, and its end stays at least 0.05 seconds after the start.
- Set the scale when the video speed changed after the captions were written. Scale multiplies the timestamps before the offset. Leave scale at 1 when you only need a subtitle timing shift.
- The words stay the same. Press Shift timing, then download the SRT or the VTT.
## Tips
- Find one line you can hear, measure how early it is, and use that as the offset for the file.
- Scale and offset together are easy to overdo. Shift first. Scale only when the drift grows through the file.
- If one scene is wrong and the rest is right, this tool will move the scenes that were already correct. Split the file.
## FAQ
- How do I fix subtitles that are out of sync?
If the whole file is early or late, shift the subtitle timing. Enter an offset in seconds and press Shift timing. Use a positive number when the captions are early, and a negative number when they are late. If the gap grows through the file, set the scale as well. This page does not change the words.
- Is my file uploaded?
No. The SRT or VTT is parsed in the page. Nothing is uploaded, and no model runs.
- What happens to a cue that would start before zero?
The start becomes 0. The end is kept at least 0.05 seconds after the start.
- Does this translate the words?
No. It only moves timestamps. The translator is a separate page, and it leaves the cue times alone.
## License
Timestamp shifting is original code in this site. No third-party model is used.
