Closed Captioning

[Aaron Star]

Captioning in Vegas is not that hard. I am not sure if Quicktime supports CC embedded into the video file. you may need to provide a side text file along with the video file.

Broadcast codecs like XDCAM have the CC embedded into the file.

Files like AVC require a side text file for the CC.

CC marking is as easy as selecting where you want the CC, and hitting C. Then select the CC format you want, and type the caption. You can then embed the CC with XDCAM, or export the CC as a file. Make sure to turn on the overlay in the Preview Monitor for the CC version you are editing.

Finally able to get back to this problem. I have a commercial that I loaded in Vegas, and it shows the captioning tags on the time line. However, the captions do not show up in preview. I have selected CC1 on the drop down in the preview monitor. Also when I render it out to an MOV, the captions are not there. Any help?

Did you read my post? You just asked the two questions that I already answered. I’ll answer them again:

[Greg Buzzell] “I have a commercial that I loaded in Vegas, and it shows the captioning tags on the time line. However, the captions do not show up in preview. I have selected CC1 on the drop down in the preview monitor. “

You must select that event and use the script under Tools | Scripting | Promote Media Closed Captioning to generate the close caption markers that Vegas Pro needs on the timeline for preview and rendering.

[Greg Buzzell] “Also when I render it out to an MOV, the captions are not there. Any help?”

You cannot do this with Vegas Pro. Vegas does not support closed captioning in a QuickTime MOV container. What Vegas Pro will do is create a QuickTime movie and a Scenarist .SCC file that you can use with Apple Compressor on a Mac to add captioning to the MOV file. You will, however, need a Mac to do this. I know of no way to do this on a PC.

Thanks for the answer. I guess I missed the previous one. Is there a format that Vegas will render to that will retain the CC? Thanks.

[Greg Buzzell] “Is there a format that Vegas will render to that will retain the CC?”

For HD, when you render to XDCAM HD/XDCAM HD422 MXF formats, captioning markers are embedded in the media file.

For SD when you render to MPEG-2 Program Stream format, captioning markers are encoded in ATSC format.

All other formats will not contain embedded captions and you will only have the external .SCC file.

We have discovered that the “Promote” option does not always work correctly (because Vegas does not always put the embedded markers in the correct location).

I have a video where Vegas reads the markers and places the first one at the 0 second mark when the first marker is actually at 10 seconds so all subsequent markers are 10 seconds off. However, if you load the SCC file that Vegas created when reading the markers, the markers are placed in the correct location. This is in all versions of Vegas I tested.
