Premiere 25.5 won't send embedded captions through to AME

[Michael374429816sex]

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.

@Michael374429816sex,

Are you using a custom preset? If not, what is the name of the preset you are using? I assume MXF OP1a?

What OS? I am on Win 11 PR 25.5.0, and tested with MXF OP1a XDCAM HD 50 NTSC 60i. With my arbitrary source media, I could not get 60i, so modified.

But I get embedded captions with PR and AME, testing by importing back to PR. I assume you have Preferences -> Media -> "Include Captions on Import" on, since you got  your source with embedded captions in.

Hi Stan, yes I'm using the MXF OP1a XDCAM HD 50 NTSC 60i preset, simply modified with the "Embed in Output File" option in the captions drop-down.  But this behaviour also happens using a custom h.264 export with burnt-in captions (for client review).

Yep, captions import is enabled and they come into Premiere just fine.  MacOS Sonoma 14.7.6.  A colleague found the same behaviour on his Windows machine (OS 11, presumably).

Hi @Michael374429816sex, 

Welcome to the Premiere Pro forums and thank you for reporting a problem.

What format are the embedded captions? If I'm understanding correctly, the issue isn't the captions being embedded, rather it's that the original media itself is showing up as offline and not exporting when sent to Media Encoder? 

Sorry for the frustration, 
Dani

No problem.

Captions are 608/708 within an MXF OP1a wrapper (XDCam HD422, 29.97fps interlace).  A fairly bog standard broadcast deliverable.

Yes, the captions import correctly, are visible within the caption tracks in the timeline (and the program monitor).  But under PP 25.5 they wouldn't translate to AME on export.  Media offline.  When turning off the aforementioned setting "Import sequences natively", the media would appear in AME but without the embedded captions.  Rolling back to 25.1 has solved this for now.
