In this excerpt from a webinar, Larry Jordan gives a detailed overview of Closed Captions in Premiere Pro. He discusses how Closed Captions are different from Open Captions and Subtitles, and explains four Closed Caption file formats. This is a very informative video and will give you a good understanding of Closed Captions and how they are used.
Closed captions are intimidating! But, closed captions are also vital to understanding a movie for anyone who has trouble hearing or speaks a different language. The problem is that creating closed captions is not easy, even though captions are required for more and more media projects today. —Larry Jordan
