System information
When the captioning markers are read, Vegas Pro creates an .SCC file in the media file's folder using the
same base name as the media file. The .SCC file is used when you use the media in the future so the
application doesn't need to scan the media again.
When you're finished editing your project, you can promote the embedded captioning markers to the
timeline:
1. Select events with captions.
2. From the Tools menu, choose Scripting, and then choose Promote Media Closed Captioning.
The markers appear as command markers on the timeline, and you can move and edit the markers
as needed:
Rendering captions
You can export captions in rendered media and in standalone .SCC files.
n When you render to XDCAM HD/XDCAM HD422 MXF formats, captioning markers are embedded
in the media file. An .SCC file is also created using the base name of the rendered media file.
n When you render to MPEG-2 format, captioning markers are encoded in ATSC format.
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.
