About SRT Time Shift
Welcome to the SRT Time Shift tool - the easiest way to fix out-of-sync subtitles. Whether your subtitles appear too early or too late, this tool lets you shift all timestamps forward or backward with millisecond precision. Upload your .srt file or paste the content directly, specify the time adjustment, and get perfectly synchronized subtitles instantly.
What is SRT Time Shifting?
SRT time shifting is the process of adjusting all timestamps in a subtitle file by a fixed amount. This is commonly needed when:
- Subtitles appear too early: You need to shift them forward (delay them)
- Subtitles appear too late: You need to shift them backward (advance them)
- Different video versions: When subtitles were made for a different cut of the video
- Encoding issues: When video was re-encoded with different timing
Quick Tip
To find the exact shift amount: Note when someone starts speaking in the video, compare it to when the subtitle appears, and calculate the difference. Use positive values to delay subtitles and negative values to advance them.
Understanding SRT Format
SRT (SubRip Text) is the most common subtitle format. Each subtitle entry consists of:
Timestamp Format Breakdown
- HH - Hours (00-99)
- MM - Minutes (00-59)
- SS - Seconds (00-59)
- mmm - Milliseconds (000-999)
The format is HH:MM:SS,mmm (note the comma before milliseconds, though periods are also accepted).
How to Use This Tool
- Upload or paste: Either drag and drop your .srt file onto the upload zone, click to select a file, or paste your subtitle content directly into the text area.
- Enter shift values: Specify how much to shift using hours, minutes, seconds, and/or milliseconds. Use positive numbers to delay (shift forward) and negative numbers to advance (shift backward).
- Use presets (optional): Click quick preset buttons for common adjustments like +5 seconds or -1 second.
- Set start number (optional): If you want to renumber subtitle entries, enter a starting number.
- Process: Click "Shift Timing" to apply the changes.
- Review and download: Check the comparison table, copy the result, or download as a new .srt file.
Common Scenarios
Subtitles Appear 5 Seconds Too Early
If the subtitle shows before the person speaks, you need to delay it. Enter +5 in the seconds field to shift all subtitles 5 seconds later.
Subtitles Appear 2.5 Seconds Too Late
If the subtitle shows after the person speaks, you need to advance it. Enter -2 in seconds and -500 in milliseconds (or -2500 in milliseconds alone).
Fine-Tuning by Milliseconds
For precise adjustments when subtitles are almost in sync, use millisecond values. For example, +250ms or -150ms for minor tweaks.

Tips for Best Results
- Test with a small sample first: If you have a long subtitle file, test the shift amount with a few entries before processing the entire file.
- Use video playback position: Most video players show the current timestamp - use this to calculate the exact offset needed.
- Consider variable sync issues: If subtitles drift over time (getting more out of sync as the video progresses), you may need a tool that supports linear correction rather than a fixed shift.
- Keep a backup: Always keep your original subtitle file in case you need to try different adjustments.
