SRT Time Shift

Sync the SRT file with your video by shifting the timecodes of your subtitles.

How to sync SRT file with video?

  1. 1. Upload your SRT (.srt) subtitle file.

  2. 2. Provide the offset in seconds.

    Write down the offset you want your subtitles to shift. Make sure that the first character is a "+" (adding) or "-" (subtracting). For example, +1.20 means adding 1 second and 200 milliseconds to every timecode.

    Click on "Shift SRT Subtitles" to sync your subtitles with the provided offset.

  4. 4. Download your new SRT file.

Frequently Asked Questions

When should I use the SRT Time Shift tool?

You should use this tool when the subtitles of a movie are out of sync with the movie. This happened when the subtitles were created using a different version of the movie. For example, when the version has a longer intro than the current version.

What are the supported time units?

We currently only support shifting by seconds (s) and milliseconds (ms).

How do I determine the offset?

You should start the offset with either a "+" (adding time to) or "-" (subtracting time from). Then, write your offset in seconds and, if you need to use milliseconds, you add them after the decimal separator "." (dot). For example, to subtract 200 milliseconds, you write "-0.2".

My subtitles were fine, but it said, "Your subtitles have a line without start time"?

If your subtitles were correctly timestamped, it could be that your file was not in the correct file encoding. For our subtitle timeshifter to work, you need to convert your file to UTF-8.

  • Great product!
    I'm just starting a podcast and the transcript was invaluable in helping me create notes to go along with the video. The accuracy was better than I expected. It was helpful to also have the timecode noted. I highly recommend this product.

  • A great time saver
    A great time saver Happy Scribe works increadibly fast. My file is transcribed in 10 minutes. The only thing is when I try to correct some things, it takes a long time for the program to show the changes. But overall a great time saver!
