NewTek 3Play™ is a member of the NewTek family of video production systems and software, and enjoys a proud heritage. A bona fide video pioneer, NewTek is justifiably proud of its record of innovation, ongoing commitment to excellence and superb product support.
NewTek 3Play™ 4800 is a multi-channel high definition video device supporting simultaneous recording, display and smooth slow motion replay of as many as eight audio and video sources . 3Play’s outputs include professional quality connections capable of distributing two fully independent video channels (designated Channels A and B) to external video systems, such as live broadcast switching equipment. Alternatively, these two primary outputs support a video switcher style program-preview workflow, complete with transitions. Too, 3Play supports selectively publishing data to internal and external file storage, ftp and social media platforms on the fly.
