P: Problem with Caption encoded file exported from Premiere Pro to Encoder.

Recently went through this issue and figured I should report it here:

I was working on a project recently using a source master with embedded captions (XDCamHD50 NTSC 60i).

I did some graphics work/title overlays, but needed to preserve the captions when re-exporting to the same format (XDCam50 w/embedded CC).

Sending the sequences to AME resulted in the underlying footage from the source master as appearing offline.  Graphics and slate showed up no problem.  Disabling the AME setting "Premiere Pro/Import sequences natively" would bring the media in, but not the embedded captions.

Note that I could export using the same preset directly from Premiere Pro with captions embedded, without issue.

The only fix I found was rolling back Premiere and AME to 25.1. So this may be a bug with 25.5.

Hi. I have the same problem. I received Apple prores files that have captions in them. Exporting from Premiere is fine, but when I load it into Media Encoder, it says "offline media detected".

Windows 11

Premiere 25.2.3 (build 4)

Media encoder version 25.2. (build 141)

Replicated and upvoted. PR 25.2.3 and AME 25.0.0. Win10.

I imported a VERY short MXF file previously created in PR with embedded 608 and 708 captions. New icon to create matching sequence, and exported to MXF OP1a with captions set to embed. It exports correctly from PR. When queued to AME, it shows the warning to the right of the queue entry, indicating my source file as the missing asset. When ignored, it creates a file with embedded captions, Media offline visual, and no audio. When reimported to PR and a sequence created, it has both 608 and 708 captions embedded. I had "import natively" set, and if changed, I saw no warning, but it encodes with Media offline visual, no audio, and only 708 captions on reimport to PR.

Same result in Beta PR 25.3.0.59 with Beta AME 25.3.0.55. I filed a bug report there. I suspect this is an AME bug, but they'll sort that.

Yes captions are embedded in the file.  If the file doesn't have captions embedded, there are no problems in Encoder.

Yes they are already embedded.  This has never been a problem in the past, exporting a sequence with clips in it that have embedded captions in them.

@scottm52994640,

By "caption encoded" do you mean you have set the captions to embed? Or are they already embedded when imported to PR?
