"TEncoder is a multithreaded video and audio converter that uses
MEncoder, MPlayer and FFMpeg. It can convert almost every video and
audio type to each other. Subtitles with same name as video can be
hard-coded into video. Up to 8 simultaneous encoders can be run so
encoding time decreases. You can select between multiple audio and
subtitle tracks. Extracting video or audio content is possible. Edit
