System information
Closed Captioning
Vegas Pro software supports adding closed captions to video files and rendering those files as XDCAMHD
and XDCAMHD422 MXF files. You can also add captions to video files and render as Windows Media
Video for use in Windows Media Player.
Adding Closed Captioning to Video Files
Closed captions help make your video productions accessible to a wider audience. Closed captions are
widely used by viewers who are deaf or hard of hearing, those who are learning to read, or who are learning
a second language.
Closed captions can be turned on or off by the viewer (unlike open captions, which are always displayed).
Closed captions display spoken dialogue and sound effects as on-screen text.
Notes:
n Vegas Pro supports CEA608 captions and CEA708 containers containing CEA608 captions.
n When rendering to XDCAM HD/HD422, CEA608 data is uplifted to CEA708 format so that
CEA608 and CEA708 captions are available when playing via HD SDI. CEA608 CC1 is uplifted
to CEA708 Service 1, and CEA608 CC3 is uplifted to CEA708 Service 2. Please note that
caption positions can be slightly different after uplifting to CEA708.
n When you render to a format that does not support embedded captioning markers, an .SCC
file is created using the base name of the rendered media file.
Importing or rendering closed captions in an MXF or MPEG-2 file
Importing captions
Vegas Pro supports closed captioning embedded in XDCAM HD/XDCAM HD422 MXF and MPEG-2 files.
ATSC and SCTE formats are supported when reading captions in MPEG-2 files.
When you add media to the timeline or Trimmer, embedded captioning markers are displayed as media
markers:
Markers are aligned with the start of captioning for paint-on captions or with the display time for pop-up
style captions.
