Captions can be prepared in several different styles.
- Placed Pop-On Captions: Captions are synchronized to the programming, and placed to visually indicate the speakers. They are timed and placed to synchronize with the program. Pop-on captions look similar to subtitling and can be positioned anywhere on the screen to help indicate who is speaking, or formatted to indicate “off-screen” dialog or sound effects.
- Stationary Pop-On Captions: Captions are centered at the bottom of the screen with speaker changes noted by a dash.
- Roll-Up Captions: Captions scroll onto the screen in a continuous flow and use chevrons (“>>”) to denote speaker changes.
