Different kind of subtitles

1) Burned-in subtitles (or "hard subs")

Which can be compared to "hot iron cow branding" Now that they're burned in the image, there is no way to make them disappear properly, as they're totally part of the image. These burned-in subtitles won't appear in VLC subtitle menu and there is no way to hide them

2) Soft subtitles

Imagine our movie is a single AVI file. Those "soft" subtitles are hidden somewhere within the AVI file, but they're not burned in the image. You may find different languages for these soft subtitles (for example up to 8 different languages in the same AVI !) Those soft subtitles will appear in VLC subtitle menu (one menu bar = 1 language) and you can tick the one you want (or untick all if you don't want to see any subtitle) At least, you know they are embedded in the movie and you can make them appear or disappear at your wish.

3) External subtitles

These are external individual files: most usual are .srt files (which contain only 1 language) or the couple of files .sub + .idx that may contain up to 32 different languages !)


If you want those external subtitles files to be opened automatically when you double click a movie in Windows Explorer, then you'll have to give those external subtitles files the same name that your movie, for example :

Dark Star.avi <= the movie file

Dark Star.srt <= the external subtitle file

If both names match, then VLC will automatically open the subtitle file and display subtitles, as soon as you double click the movie file name. This 3rd kind of subtitles (external files) will appear in VLC subtitle menu, and you can tick /untick them, at your wish.

For more information see how to enable / use subtitles


Subtitles formats

There are a lot of different types of external subtitle files. Most contain textual data. That is the subtitle and a timestamp at which this subtitles is to be shown. Some of these allow for additional formatting, others don't.
