Split a subtitle file
Cut a subtitle file at any timecode, divide it into equal parts, or keep just one range. Each part can restart at zero. Nothing is uploaded.
Splitting is the job you have when the video was split first: a film that arrives as two files, a lecture cut into chapters, a three-hour recording being published as episodes. It is also how you pull one scene out of a long transcript. The interesting decision is not where to cut — you know that — but what happens to the line being spoken across the cut, and whether each part should be timed from the start of its own video or keep the numbers it had in the original.
Worth knowing
- The cue that straddles a cut goes to the part where it starts, whole. It cannot be in both parts without the line being spoken twice, and dropping it would lose dialogue outright.
- "Restart each part at 00:00" is what you want when each part has its own video file: part two is re-timed so its first cue sits where it belongs in part two's video. Turn it off to keep the original timeline, which is what you need if the parts are going back together later.
- Splitting into equal parts divides by the clock, not by the number of cues — a talky first half and a quiet second half still cut at the midpoint of the running time, because that is where the video was cut.
- A part with no cues in it is listed as empty rather than quietly skipped, because an empty part means a cut point landed before the first line or after the last one, and you probably want to know.
- Cut points can be stamped from your own video: play it, find the moment, and the timecode is filled in for you — no arithmetic on a timecode you read off a player.
FAQ
I split my file and part two starts an hour in. How do I fix that?
Switch on "Restart each part at 00:00". Without it, every part keeps the timing it had inside the original file, which is right when the parts will be recombined and wrong when each part has its own video starting at zero.
How do I keep just one scene and throw the rest away?
Choose "Keep one range" and give a start and an end time. Cues that begin inside the range are kept whole — including one that runs past the end — and the result is re-timed to start at zero so it matches a clip exported from the same range.
Can I split a file that is not SRT?
Yes. Anything the site reads can be split — VTT, ASS, SBV, MicroDVD, TTML, SAMI, LRC, JSON and CSV — and each part can be saved in any of those formats, not only the one you started with.
