Vegas Pro 16 does not automatically scan for embedded closed captions

Jas710 wrote on 7/4/2019, 6:32 AM

Our previous Vegas Pro was 13, and we recently installed 16. The pc is a 64-bit Windows 7 Pro machine. It works well, except when a video clip known to contain closed captions is dragged into the timeline, it doesn't detect the cc, thus doesn't generate the usual overlay. I am aware of the hidden options menu and the true/false setting for the reading function, and have tried to go false and back to true again, restart, etc, but it doesn't fix the issue.

(It does partially work however. If there happens to be an existing scc file with a video, such as a leftover after running it through 13, 16 knows to grab the file and adds the cc overlays no problem.)

Additionally, if I decide to go back and put the same video in 13 (which is still installed on the same pc; I kept it installed in case there were any issues with 16, such as this one I'm posting about), 13 is still able to scan for the closed captions and loads the overlays as expected.

I've tried searching and most of what's out there are either how to import/export/render CC's, or how to turn off the reading function.

Has anyone experienced this issue on 16? Any suggestions on what may be causing this, and what might resolve it would be appreciated.

Thanks!

I also need a solution for the same problem. I have tried it on 4 computers with the same issue.

Which kind of video clip containing closed captions do you use (file type and codecs) and which standard for closed captions is used in these files?

Hi Marco,

In my case, it's mpg1/2 (mpgv), with both the EIA608 and EIA708 cc standards. Odd that in Vegas 13, the file is immediately scanned and a scc file is generated once it gets dropped into the timeline, but if I perform the same steps in 16, it doesn't do it at all. I also recently tried testing on Windows 10 as well, and it still didn't scan for/generate an scc file.

I just tested with VP13, VP16 and VP17. For the MPEG-2 media file with closed captions I have available, in all these Vegas Pro versions I need to use the given script "Promote Media Closed Captioning" to make the Vegas preview show the closed captions.

Did you try running this script?

Yes, I've tried it, but it has no effect since it needs an scc file to make the initial orange cc overlays to work with. If I can get those, then the 'promote media closed captioning' script works fine, with the blue markers and previews and all that. It's just that it seems like Vegas 16 doesn't want to create an scc file for me to get to that point, like Vegas 13 could.

I see. Yes, I tested with a file which already had a SCC file beside.

Could you share such a sample MPEG-2 file with embedded CC for download?

That is an apple codec. Maybe you need to enable QT support? I don't have V17 but from what I have read. QT support is disabled by default.

It's not an apple codec, it is a MPEG-2 video stream (MPEG-1 Layer 2 audio stream) wrapped as MPG. It doesn't work with VP16 either. The closed caption scan simply doesn't work in VP16 and VP17.

I will send a bug report now.

I see it still works fine if the Closed Captions are embedded into MXF XDCAM HD. But it does no more work for CC embedded in MPG MPEG-2.

I was going by his description which was "mpg1/2 (mpgv)". this is an apple mpg codec.
