Embedding Closed Captions in a single video file for broadcast

[Anonymous]

Help. We are trying to get back on the air after a 15 yearhiatus. We’ve upgraded all of our cameras, cabling, switching, capture and editing to HD. I chose to use Sony Vegas Pro for my editing because it can render our final video file in HD format andembedcaptions in the file. The problem i’m having is trying to produce a file that the tv station we are trying to air on can view. I’ve tried MXF files, MP4’s, MOV’s, AVCHD, and just about about every HD format exportable by our software and the station has yet to give us an “OK” on viewing the file and captions. They are also not very forth coming in giving me details as toexactlywhat formats they CAN accept and what they know works for sure.

I’d like to ask you guys, the professionals, what software/formats do you KNOW to work in delivering HD and Captions in a single file. I really don’t want to spend another $20,000 on a deck to deliver content on tape when usb drives are muchcheaper.

I’m using Vegas Pro 11 right now butI’vealso tried Adobe Premiere and Final Cut Pro.. those do not seam to support this feature.. or at least not that I’ve found.

what format has the station asked for? Are they downconverting to SD?

I’ve gotten several different responses.. And no straight answer if they are down-converting.. but they do have a 1080i hd signal that i can pick up at home.

So far they have said:

>John, Just spoke with our engineering dept. and they are saying to sent it in this format H.264. Thanks!!

>Hey
John its Edward in production to answer your questions, engineering has
informed me that 708CC1 is best for HD keep the file formate of your video at
the same specs as you first sent to us the XDCAM MXF file formate

NO
we can not use the SCC/MCC files in the VR the only option is to have the Close
Caption In-bedded into the XDCAM as per the test files you sent our VR did not
accept them so please do not step away from the first formate you sent us or
change any options.

My advise to you is keep your video formate constant
and have your software vender figure a way to in-bed the close
caption hopefully I answered your questions

>John,
When sending HD video we need you to use XDCAM 50mb/sec. Also when
sending long format video use H.264 compression using high quality
setting. When working with embedded Closed Caption data internal to
FCP system use ProRes 422 codec.
