Hello, Looking for some help on a Project I am doing. 

I am taking a Video that is full edited and adding Closed captions that were done by a third party. Video is on V1 and Closed Captions on the CC Channel. 

 

I go to Export- Format is MXF OP1a and Codec is XDCAMHD NTSC 720p

Once exported I check it in VLC and i dont see captions. I also bring it back into Premiere and Dont see captions. 

I did a test with a prores export and added the Embeded captions and it worked no problem.... I could not see the captions I added in Premiere but i could see them in Quicktime. 

what am I doing wrong with the MXF File. 

Thanks in advance.

Stan Got it to work! A few things... the captions must be a 608-1 format to export out as a MXF. 

 

Also you having me turn on the "include captions on import" worked... but I had to restart PR for it to kick in. Once I did that I was able to check my clips and they worked. 

THanks for the help,

Shawn

Others say you can do it, but I have never been able to see embedded captions in VLC. Test by importing back to PR. And by looking at the file with Mediainfo or similar.

I am adding the captions in PR and then trying to check them in VLC. I cant see them. Because I cant see them there I have tried to bring that same clip back into PR to see if i can see them and I still can not. 

 

Not sure what i am doing wrong.

Thanks for responding and for providing the detailed information.

 

The PR properties do not show captions even if they are present. I was not sure about that until I just checked in response to your question.

 

In preferences, check Media -> Include captions on import. Be sure you have this checked. For a time, we thought it was not working (captions were imported whether checked or not), but I just confirmed (in 22.5) that it must be checked for mxf embed caption to be imported.

 

Drag the imported file to the new icon to be sure it creates the correct sequence.

 

If that is not it, we'll move to the next troubleshooting tests.

 

Stan

Look at the file in media Info. But QuickTime seems to confirm you embedded the Captions

Sorry; forgot Media Info is windows only. But if you can see the captions in QT, they must be there. Be sure you won't have a matching srt filename....

 

What format captions? They must be 708 or 608, or embed wouldn't show as an option in the export screen.

 

Not seeing the problem yet....

I cant play this MXF file in quick time.... I did a seperate test export as a prores just to see if i could see them on anything at all. I took that ProRes clip into quick time it works. 

The MXF file is what i need to work for boardcast. All of the ways I ahve shown you to try to check if it has the captions- have not worked. I have on it 708 format.

Shawn, excellent! In the end, I have no explanation for why it now seems to work.

 

a) Your file worked for me. It has 708 and I imported it successfully to PR.

 

b) There was a bug regarding the "import captions with file" preference, fixed prior to  your version 22.3 (I think). However, the fix required that the media cache be cleared, possibly only for files that had been previously imported. In any event, I did not try testing the preference issue it again until the current release version 22.5, and I thought it was still broken. I cleared the cache, and it started working. I am not suggesting that was your problem, but as an example of odd things that may make it appear there is a problem.

 

But create the file with a file name you have not used before and see if that imports.

 

c) 708 can be embedded in mxf, as can 608, and both 608 and 708. In PR at least, only 608 can be embedded in QT.

 

d) Yes, I'm PC and you're Mac and that can make troubleshooting harder.

 

e) The only reliable test for embeds for me so far is Telestream Switch. I tested the free version 5.0. In the free version, captions text is not displayed, but an “upgrade needed” message shows that the captions are there.
