Another option is to get SubRip from here. This essentially creates text files though the .srt extension. To create your own subtitles, the best software is a spanking new one called Aegisub, so grab it here.
There used to be the famous Substation Alpha software, which is not being updated anymore, though it deserves a mention in any subtitle article. The file type it generates is .ssa (again a text), and the mentioned Aegisub supports it. Further, .srt files and many others are also supported.
The last, and easiest, thing you can do is download .srt or .sub files from the Internet.
Adding Subtitles
There are two types of 'subbing': hard and soft. Which do you need? Wait, before that, what do they mean? Hard subbing means permanently adding the subs to your video (it will be in the pixels), whereas soft subbing lets you view the video with separate subtitles files being called by the codec, mainly in MPEG 4 part 2 and part 10 file types like DivX, Xvid, and H.264. But if your DVD player doesn’t support DivX and you have only a VCD option, hard subbing is mandatory.
Soft subbing is actually a misnomer; you have to just download the subtitle file, install Vobsub, place the file in the same directory, and watch the clip on something as generic as Windows Media Player. Don’t forget to rename the file to the movie’s name. Even if you create your own subs with Aegisub, you can export and save as normal .sub or .srt subtitle files and view them. Aegisub can be used to do timing and resynching edits, adjust frames per title, adjust colors of the subtitle, and every other small whim. The learning curve is quite flat too.
