System information
Markers are aligned with the start of captioning for paint-on captions or with the display time for pop-up
style captions.
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 Line 21 captions
Line 21 captions are supported during rendering when using a frame size of 720x486 pixels (or taller) and a
frame rate of 29.97 fps.
Please note that encoding line 21 captions for DVD is not supported. MPEG-2 video for DVD cannot
exceed 480 lines of resolution. DVD line 21 captions are embedded as metadata in the MPEG-2 video
stream and are not supported.
Importing or printing captions when using HD SDI
Importing closed captions over HD SDI
Vegas Pro reads embedded VANC closed captioning when capturing video over HD SDI.
n During capture, Vegas Pro creates an .SCC file in the media file's folder using the same base name
as the captured file.
n If capturing to XDCAM HD422 format, closed captions are also embedded in the captured file.
For more information, see "Capturing from an SDI Card" on page 122.
