.sub File Extension

Developer: N/A
File type: Subtitle File
You're here because you have a file that has a file extension ending in .sub. Files with the file extension .sub can only be launched by certain applications. It's possible that .sub files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .sub file?

Files with the .sub extension are essentially text documents containing subtitle details of digital videos. Videos that will use these SUB files should be saved in the DivX or MicroDVD format, and there are other video formats with compatibility support for these SUB files. Aside from the subtitle text for a particular video, details of specific cue points must also be included in a SUB file. These cue points instruct the application used to view the video about the correct timing sequences specific subtitles should be displayed. This means video files developed with an associated file in the SUB format finds and use the associated SUB file when the user enables subtitles during video playback. MPlayer, both versions for Mac and Microsoft Windows, provide compatibility support for digital videos that use SUB files, while popular text editors like Microsoft Notepad and Microsoft WordPad can be used to open and view the content of a SUB file.

how to open a .sub file?

Launch a .sub file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .sub file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .sub files aren't yet associated with it. In this case, when you try to open a .sub file, you can tell Windows which application is the correct one for that file. From then on, opening a  .sub file will open the correct application.

MPlayer

MPlayer

The MPlayer software is a free media player application, and this program is usually categorized as freeware. However, the MPlayer application is actually an open source program, which means its source code (the foundation of its software) can be edited, improved or enhanced by anyone. The MPlayer program is also supported by major operating systems like Microsoft Windows, Apple Mac OS X and various Linux as well as UNIX distributions. OS/2, AmigaOS, Syllable, AROS Research OS and MorphOS are also implemented with support for the MPlayer application. This program can even work on Microsoft DOS (Disk Operating System) with the use of the HX DOS Extender (Microsoft Windows version only). The MPlayer software has also been ported to several devices with the use of third-party community plug-ins, including one for Amazon Kindle. The MPlayer program looks a little like the VLC Media Player application and has inherited the latter's ability to play any type of media content known to most users, and even save streamed media content to a file on the local machine. MPlayer also supports a companion application called mEncoder, which is primarily used for streaming content input and for transcoding it to several output formats, with a few additional video transformation processes implemented into its operations.

a word of warning

Be careful not to rename the extension on .sub files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .sub. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
