Voody Blue Subtitler is a suit of programs that allows you to manually synchronize a text file with a video stream, thus creating a subtitles file. It consists of a master client (to do the sync), a slave client (projector), a relay server, and a configuration utility. It runs on Linux and Windows (all except the relay server), supports video output via GStreamer (Linux and Windows) and MPlayer (on Linux only), and supports GTK+ 2 and 3 (decided at compile time).
