How to fix SRT subtitle timing with a time shift

If a subtitle appears before someone speaks, or stays consistently behind the dialogue, a timing offset may be enough to fix it. Cadava’s SRT Subtitle Editor can shift all cues by the same amount. It edits an existing subtitle file; it does not listen to audio or generate a transcription.

Decide whether the delay is constant

Check a subtitle near the beginning, middle, and end of the video. If all three are about two seconds early, a constant shift is a reasonable starting point. If the mismatch grows from one second to ten seconds, that is drift. A single offset moves the whole file but cannot stretch its timing to fix drift.

Different cuts of a video can also have missing scenes, extra introductions, or other changes. In those cases you may need cue-by-cue adjustments in a video-aware subtitle editor. This browser tool has no synchronized video preview, so check the result in your player.

Understand an SRT cue

A standard cue has an index, a start and end timestamp, and one or more text lines. Blank lines separate cues:

1
00:00:01,000 --> 00:00:03,000
Here is the first subtitle.

The comma separates milliseconds: 01,500 means one and a half seconds in the seconds position. Keep hours, minutes, and seconds separate, and ensure each cue ends after it starts. The editor accepts UTF-8 SRT files and rejects unsupported timestamp syntax rather than silently guessing.

Apply a shift in the correct direction

1. Open your .srt file in the SRT editor, or paste its contents.
2. Select Validate SRT to check the structure.
3. Enter a shift in seconds. Use +2 for subtitles that need to appear two seconds later, or -2 for two seconds earlier.
4. Select Apply time shift, then download the SRT.

The shift applies to the current text. Applying it twice shifts twice. If an earlier shift would put a timestamp below zero, the operation is rejected. Keep a copy of your original subtitle file so that you can restart easily.

Review before publishing

The editor checks basic structure and flags overlapping or out-of-order transitions. It does not judge reading speed, subtitle accuracy, or whether each line matches the speaker. Downloading renumbers cues in their existing order; it does not sort them. Watch several sections of the video after making changes.

For creating text from recordings on Android, Scribe offers an offline speech-to-text workflow with SRT export according to its store listing. Always review generated text and timing before sharing subtitles.
