How do I split long subtitle cues into multiple readable lines?

Upload your subtitle file, configure maximum characters per line (e.g. 37 chars) and maximum lines per cue (e.g. 2 lines), and click 'Auto Split'.

Why should subtitles not exceed 2 lines on screen?

Subtitles with 3+ lines block too much video area and overwhelm viewers. Standard broadcasting limits subtitles to 2 lines.

Does the splitter respect natural grammar and sentence breaks?

Yes. Splits text at natural punctuation marks, commas, and conjunctions rather than breaking words arbitrarily.

Can I split a long movie subtitle into CD1 and CD2 parts?

Yes. Split by timestamp threshold to divide subtitles across disc parts.

What formats are supported?

Supports SRT and VTT subtitle files.

Is processing done locally?

Yes. All text processing runs in your local web browser.

Formula Variables Explained:
Partitions cue arrays into independent timestamp ranges with normalized timing.
