Embedded sequences dropping frames on export in Adobe Media Encoder

I have a timeline for a 30-minute show. In the timeline, there is raw video, audio, and for pre-done packages, there are embedded sequences. Playing back inside Premiere Pro there is no issue. Everything plays perfectly smoothly. When I render the show in Adobe Media Encoder (AME), some parts of the embedded sequences have major dropped frames. I noticed this only when I went to make the promo and the talent on green screen played fine, the video underneath, which was from an embedded sequence, was dropping frames, but only upon export with AME. Playing on the timeline was fine.

For the promo, I noticed that if I switched off "Import Sequences Natively," the render was fine. However, I could not do that when I had to re-export the show, as AME still has an issue where it keeps burning in the closed captions into the video regardless of settings.  So, my only fix was to render the shows back out directly from Premiere Pro.

 

Any Ideas?

Hi, so you mention two issues here. The dropped frames and the burn in of subtitles regardless of state. The latter I tried to repro with the latest beta version on AME but couldn't. 

My testing looked like this:

- in PPro create a project with a sequence containing a CC track

- save project and open / drag project into AME (import sequence natively)

- enter export settings and change "burn in captions" to "create a sidecar file"

- export

 

The result was (in my case) a mp4 and a seperate .stl sidecar containing the subtitles.

Does this also happen in direct export? Can you share a project and media? I can send you the instructions via private message in this forum.

Sorry, for some reason, replies keep getting blocked in spam.
The dropping frames was fixed in a subsequent version. ​@ChWard  was correct, I mistakenly placed two topics in my post. The problem that still persists is when importing media with closed captions (an MPEG 2 XDCAM MXF), the captions show up correctly in PPRO. However, if you export the project in AME, you can’t stop the captions from being burned in. Exporting natively works fine. I am currently working on so many project at the moment (broadcast TV station), I will have to re-open up that older project, or do a test with a new one to see if it is still a problem as it was a couple months ago. Sorry for the delay.
