[Greg Buzzell]"Can I embed an SCC closed caption file to a video? When it is embedded, what format can I export it as so that the CC will be embedded in the video for broadcast?"
Yes. When you render to XDCAM HD/XDCAM HD422 MXF formats, captioning markers are embedded in the media file. Also when you render to MPEG-2 format, captioning markers are encoded in ATSC format. Those are the only two formats that support embedded closed caption with Vegas Pro. I would use Sony MXF HD422 1080p 50Mbps for broadcast delivery.
Thanks for the info. However, I need to render either to MOV or MPEG2. I have noticed that Vegas has trouble rendering to MPEG2 in 1080i when you try to do 20mbytes for a bit rate. Any suggestions on that?
