Adobe Premiere Pro CS5.5 adds the ability to attach a closed captioning data file to a sequence and preview the closed captions in the Program Monitor panel or on an external video monitor.
To preview the closed captions on an external video monitor, closed caption display must be enabled for the monitor. To preview the closed captions in the Program Monitor panel in Premiere Pro, choose Closed Captioning Display > Enable in the Program Monitor panel’s panel menu (the little icon in the upper-right corner of the panel).
Premiere Pro can send closed captions to a DV monitor without any additional plug-ins. To send closed captions to other devices, you must use a third-party device and plug-in to read the closed caption data associated with a sequence and write that data into the video frames on output. Third-party hardware partners are adding support to send closed captioning data to their hardware output. At the time of this writing, MOTU and BlackMagic Design have already announced products to perform this task.
The closed captioning data that Adobe Premiere Pro CS5.5 can attach to a sequence can be in either .mcc files for CEA-708 data (for high-definition TV) or .scc files for CEA-608 data (for standard-definition TV). For information on closed captioning formats, see the “Closed captioning” page on Wikipedia.
Adobe Premiere Pro does not create closed caption data.
Additional information about the closed caption features of Premiere Pro CS5.5 is provided and discussed in this thread on the Premiere Pro user-to-user forum.
