Split a Subtitle File

How to use the SRT Splitter

1. Drop a subtitle file. The info line shows how many cues and how long it is.
2. Choose how to split: at one time (two files), into N equal parts by duration, or every N subtitles.
3. Keep Restart each part at 00:00:00 ticked if each part belongs to a separate video file; untick it to preserve the original timeline.
4. Click Split file and download each part or all of them as a ZIP.

Split modes

• At a specific time — gives two files: everything before the cut and everything after. A cue that crosses the cut stays in the first part.
• Into N equal parts — divides the total running time; good for cutting an episode into thirds.
• Every N subtitles — useful for translation batches, e.g. 200 cues per translator.

Why restart each part at zero

If a movie was cut into two video files, the second file starts at 00:00:00 again. The subtitles for it must start at zero too, otherwise nothing appears until the equivalent time of the whole film has passed. Restarting shifts every cue in the later parts back by the start time of its part. If you want to keep one long timeline, for example for a translation job, untick the option.

Combining the process with other tools

1. Split a file at the point where the second video starts.
2. If the second part is still not matching, use the timing shifter.
3. If you later need one file again, use Join SRT with a gap between parts.

Formats

The output uses the same format as the input. ASS files keep their style header and fonts in every part.

Example: a 100-minute film on two discs

The first disc ends at 0:52:10 and the second begins at the start of the story again. Enter 0:52:10 as the cut time with Restart each part ticked. You receive part1.srt with everything up to 0:52:10 and part2.srt that starts at 00:00:00 — a cue originally at 0:52:30 becomes 0:00:20. If part two is a few seconds off afterwards, correct it with the timing shifter and not by splitting again.
