Description: Download SubDialog from the official site
Description:
This software edits the way dialogues in subtitles are presented. When lines from two characters are shown at the same time, the first and the second line should begin with a hyphen. This is not always the case; sometimes the first hyphen is omitted, particularly in subtitles created by laymen or translated from another language.
SubDialog can fix this by inserting a second hyphen where needed. It is actually a two-way converter so if you prefer the dialogues with only one hyphen (in the second line), it can be done as well.
For the application to run, the Microsoft .Net Framework must be present on the computer. Usually it is already there, since many newer applications install it silently, e.g. the ATI drivers.
