Splits dialog lines into one subtitle per speaker (subtitleedit#14917):
00:00:01,000 --> 00:00:04,000 00:00:01,000 --> 00:00:01,738
- Andro! → Andro!
- Ben, I've been oozed.
00:00:01,762 --> 00:00:04,000
Ben, I've been oozed.
Built on Avalonia and the shared Plugin-Shared library.
The same rule as Subtitle Edit's own dialog helper: a line starting with a dash
(-, ‐, – or —) starts a new speaker when the line before it ends a
sentence (., !, ?, …, ♪, ), ], an interruption like foobar--,
...). So all of these split:
- Andro! Andro! - How are you?
- Ben, I've been oozed. - Ben, I've been oozed. - I'm fine, but I would
have been better with candy.
Unlike Subtitle Edit's check it is not limited to two or three lines - a
subtitle with three speakers becomes three subtitles. A double dash (--and then) is a continuation, not a speaker.
Uncheck Only split where the line before the dash ends a sentence for languages without sentence-ending periods, or subtitles that leave them out.
- The dash is removed from every part.
- The time is shared out by text length, as Subtitle Edit's Split does: equal halves when the parts are about as long, otherwise weighted, with no part getting less than a quarter (for two parts) of the time.
- Gap between lines (ms) is left between the parts (default 24, Subtitle Edit's default minimum gap).
- Formatting carries over:
<i>- Hi!/- Hello.</i>becomes<i>Hi!</i>and<i>Hello.</i>, and ASSA override tags such as{\an8}are repeated on each part. - Advanced Sub Station Alpha and Sub Station Alpha files are edited in their own format, so styles, actors, layers, margins and comments are kept. Other formats are edited as SubRip, like the other SE5 plugins.
A preview with one row per dialog line: checkbox, line number, the line before (with its start time) and the new lines after (with their start times). Select all / Select none toggle every row; Apply splits the checked lines and registers a "Split dialogs" undo entry. The two options are remembered between runs.
Split dialogs supports Subtitle Edit's Batch convert (Tools → Batch convert → Run plugin; needs a Subtitle Edit version with plugin batch support).
- Configure... opens the window without a subtitle to set the two options (Only split where the line before the dash ends a sentence and Gap between lines (ms)). They are the same remembered options as in a normal run.
- During the batch every dialog line in each file is split without showing the window - the same as clicking Apply with every row checked (the window's default). Files without dialog lines are left as they are.
