Media export problems
I am exporting 1080i 29.97 commercials for station dubs. I have an 8 core mac and monitor through a Blackmagic Multibridge Pro. My storage is a pair of Rorke fiberchannel arrays. The exported media often has errors like audio from earlier in the spot repeating at the end and dropped video frames. This happens when I export directly from Premiere, queue it through Media encoder or open the project in Media Encoder for rendering. It happens whether I export as the final dub format (mp2) or match the sequence settings. Any ideas?

What information can you provide on the audio files? Like format, sample rate,etc.

The source audio is 48K AIFF from ProRes422 source. The output is either the same or mp2 with the same results. Right now I work around it by re-doing the export. The errors occur intermittently and in different places. For example, audio from the beginning of the spot might be repeated in the middle but if I re-export the audio from the beginning may be repeated at the end. It does seem to be the same audio that is repeated.
If I XML the sequence to Final Cut 7 on the same system these problems do not occur.

I could be wrong, but I could swear that PrP didnt “like” AIFF audio and preferred wav.
Someones bound to chime in.

Update. This only applies to the PC and I just realized you must be on a Mac. Never mind 😀

Just to be clear I am not importing or exporting AIFF separately- it is part of the ProRes files.

First off, Premiere Pro has no issues with AIFF files either PC or Mac, we use them almost exclusively here for all audio.
The only time I’ve seen anything even remotely like you describe is when we use AME to export multiple versions of the same file simultaneously. You send a clip into AME and then add a few more presets to that same clip, hit “Render” and you’ll see multiple video boxes rendering simultaneously.
When we do that, we very often will get glitches in the video.
But exporting directly from Premiere Pro (30 second to 1 hour shows) we have no had anything where the audio suddenly jumps around or video glitches. Do you have multiple frame rate / frame sized video in your timeline?

A thread about AIFF issues in Premiere 5.02…
https://forums.adobe.com/message/2909230
It is an older thread and Adobe suggests the issue has been resolved but it sure sounds similar to your experience.
And another Adobe post on this issue …which they say is resolved in 5.02.
