DynaCaption uses a DCAP file made by AutoCaptionTM to control your subtitling hardware.  The DCAP file works like a script or EDL (Edit Decision List) to tell DynaCaption when each caption needs to appear.

Inserter/Encoder Compatibility

Compatible with nearly all line 21 closed caption inserters that have a RS-232 interface and are suitable for real time stenocaptioning applications.

We recommend and have confirmed our system's compatibility with closed caption encoders made by Norpak and Ultech.  Other line 21 encoder manufacturers are EEG, Evertz, SoftTouch, and Link Electronics.  Links to inserter/encoder vendors...
