If you have a .sub file, but no .idx file, this tool will not work. But there is a chance that your .sub file is a MicroDVD file because they share the same file extension. To find out if it is a MicroDVD file, you can try converting it using the convert to srt tool.
Sub/idx type subtitles use pictures of text to display subtitles on the screen. This works great if you want your subtitles to work on every tv in the world, regardless of what font or text encoding the tv uses. This converter tool can be used to convert VobSub subtitles to srt so you can use them on any device.
Sub/Idx files can contain multiple languages. This tool will extract every language that is inside the file. It is not possible to only select the specific language you want, so you'll have to wait until all the languages that come before the one you want are done processing.
