About .TTS File Format
To work with TTS files in Anycount, let’s get to know a little more about this format.
TTS is the proprietary subtitle format of the TurboTitler subtitle editor. The program was designed for the Amiga computer, and is discontinued, but a number of media players and subtitle editors, like MPlayer and Subtitle Workshop, currently support the format.
