708 Closed Captioning

jmclauchlan1 wrote on 7/3/2018, 4:39 PM

We have run into a problem and only one software company can solve it. We have more and more stations wanting 708 Closed captioning and i have followed along with the forums before Magix even got a hold of Vegas and it seems that it gets mentioned but yet does not get answered. Will Magix be putting complete support for embedded 608 and 708 Closed Captioning into mpeg-2 video files. I only know of one software that will do this and that is MacCaption and i would rather stick with Vegas since i have been using Vegas since version 6. We do all of our own captioning and Vegas up to this point has been able to work. Please let me know if this is going to be fixed or do i need to jump ship and go with a different company and NLE.

Vegas already does this. It's been years since I had to do it, but I used to use Vegas to add closed captions to my videos when I had my TV show. You enter them in as markers on the timeline, with the caption being the name of the marker. Vegas puts out a file along with the mpeg 2 clip that you then can merge (the TV station did that part for me). This was back in Vegas 12-13 era, so I'm sure it can still do it.

Well... one of the reason I upgraded to V13 was to be able
to produce 708. It looked like it
worked, showed in the file that it was there.
But, no TV station could get it to work.
Last project I hired a company that specializes in CC to finish the job.

Not sure if it works
in V15 but I would not hold my breath.

If V16 included WORKING CC 708 it would be worth the
upgraded cost for that alone.

608 in SD works fine. j

We managed to get it working somehow, but I do not know what they had going on their end... I just know I had to give them a Mpeg-2 file, which I encoded at 1080p, as well as the file that was output alongside it with the subtitles, and they were able to merge them somehow and get it working.

Although it claims to encode 708, I have Version 12 and have not been able to do it. Frosty, it sounds like whoever you provided the file and the sidecar file actually encoded the CC. Vegas probably did not. I hope someone else says I am wrong, but I have not been able to get the CC encoded.

See that is the problem, the station I am working with does not have the capability to use a sidecar file. I have been doing closed captioning 608 for at least 7 years now I need 708 embedded. If it is outputted as a sidecar file then it is not embedded. believe me I have been working with this station for over 2 months and they are very specific about what they need.

I have been trying to get the 608 to 708 uplift that vegas claims to do working for years. Magix claimed they would address and fix this problem years ago but so far I have seen no progress on this matter. You can open a vegas rendered MXF file in adobe premier and see the encoded 608 information, but with Vegas13..(last time I tested it) you only got garbage in the 708 track. I just got Vegas 16 and am going to do a test file and see if the 708 captions work or not. For now,,,Adobe Premier can convert the Vegas 608 captions to 708. There is a youtube file that shows you how to do it....

...so I created a test MXF file from Vegas 16 and loaded it into Adobe Premier to see if the 708 captions were correct, and they still have problems and are not acceptable to broadcasters... The included picture shows the 608 and 708 tracks, and as you can see the 708 track does not reflect the information in the 608 track....

I'm not sure if this is a useful solution for anyone, but I've been able to use this software ($900) to take an SCC from Vegas, and generate an MXF with 608 and 708 captions:

I do also utilize this free software to re-wrap the individual essences (video/audio/CC) into a more compatible MXF:

It's a little more work/cost, but it does the job.
