Recently upgraded, Premiere to v15.1 My CEA-708 captions are not appearing when I send them to a broadcaster. My spot was rejected, and I'm having to port all my outputs to v14 to get them out the door. Has anyone done this with success? Kind of a pointless interface upgrade if it's not working. Grrr!

By any chance are you using any of the options under the Effects tab in the Export Settings? We do have an open issue with effects applied via Effects tab in Export Settings (eg: Time Tuner, Video Limiter, etc.), that we are working on. A possible workaround is to apply the effect(s) in your Timeline, rather than Export Settings (eg: apply effect(s) to Adjustment Layer in Timeline)

One other open issue we are working on involves Sequences with non-standard frame rates (eg: Variable Frame Rate, 23.98 fps instead of 23.976, etc.). Possible workaround is to create Sequence with one of the available Timebase fps options or use one of the supplied Sequence presets.

Still working on deadline.

Nothing special in terms of effects/framerate. I got it to export out properly, and passed QC on a second attempt. I believe the secret sauce was, as suggeted above by jjc.tri, that everything needed to pre-rendered in the timeline.

I believe I successfully used direct export out of Premiere, and the failed version involved using Media Encoder. I'll try again later when I've got breathing room, as it's kinda important...

The Captions Track is set to 708, correct?

And, of course, you're exporting to something like MXF OP1a that supprot captions being embedded in the file?

This is Premiere Pro 15.1.0.

What program do you suggest to view the exported file with burned in closed caption? With media info I've confirmed I have a caption file in the .mxf file but in VLC or Quicktime the caption shows up and I don't want to send a visible caption by mistake.

Thanks

"Burned In" implies exactly that... It becomes an "Open Caption" aka Sub-Titles, which are a permanent part of the video. Think "Flattened". It's sometimes used to show clients a proof of the captioning, when they don't have the technical gear required to review actual captions. What you want is "Embedded" captions, which puts the CC into a special area of the file. VLC can show captions, but you should be able to turn them off: VLC - Play a DVD with Closed Captions (swtc.edu) QT Player will only show captioning if it's certain codecs, and you have "Show Captions When Availble" turned on. This is my Adobe Export template:

I don't think you can do both "Embedded" and "Burnt In" to the same file, at least in a single pass.

Are you saying that the CEA-708 captions were not embedded in your exported file? Could you provide the steps that you went through? This will help in diagnosing.

Thank you.

I had the same problem. You'll have to render 1st, then add captions and rerender. Not a huge deal if you are using QTProRes. It won't re-transcode the video just embed the captions. Then use MediaInfo to check if they are embedded.
