Linux fansubbing aka subtitling

Fansubbing, a.k.a. fan subtitling, is the process of taking a video or movie in a foreign language and adding your own subtitles to it so that people who don’t know the original language can watch and enjoy the work. This guide describes how to produce DVD to DVD fansubs on the Linux platform using free software. Because I am only familiar with NTSC video, the discussion is restricted to the NTSC format only.
