The ability to use regular expressions to filter out unwanted instances within subtitled text
For example: “-（ルドリス）トゥンムー！ -（モモ）いや 怒ってんじゃん”
I’d much rather have a cleaned version similar to: “トゥンムー！ いや 怒ってんじゃん”
Useful examples of regular expressions
([\(（]([^\(\)（）]|(([\(（][^\(\)（）]+[\)）])))+[\)）])
Remove names enclosed by parenthesis to indicate speakers (e.g. “（山田） 元気ですか？”)
(.*)\n+(?!-)(.*)
Some subtitles are split in several lines and this regex forces them into a single line. For this filter to work, you must also put $1 $2 in the “Subtitle regex filter text replacement” field.
NB: When using this regex pattern in combination with other patterns (using the | operator, see below), place this pattern at the end. This ensures that all other regex transformations are applied first, and then the results are finally combined into a single line.
-?\[.*\]
Remove indications enclosed by square brackets that sound or music that is playing (e.g. “[PLAYFUL MUSIC]” or “-[GASPS]”)
^[\-\(\)\.\s\p{Lu}]+$
As an alternative to the above, filter out descriptions written in capital letters, but without the square brackets (e.g. “PLAYFUL MUSIC”). If your language has additional letters with diacritics, you feel free to add them to this list.
[♪♬#～〜]+
Any combination of symbols on their own that represent playing music (e.g. ♪♬♪)
Combining regexes
Regular expressions can be combined with the character | (no spaces needed in between). E.g., if you want to use the two regexes from the list above, you can use -?\[.*\]|[♪♬#～〜]+. You can combine as many regexes as you wish this way.
