I’m experiencing a repeatable export issue in Premiere Pro Beta 27.

When I export a sequence, Premiere is creating two separate files instead of one completed video file:

• 04 Social.mp4 — video
• 04 Social219ef3b2-e0b6-4d97-9bfb-7ccdfe61236f.aac — audio

Expected Behavior

Premiere Pro should export one MP4 file containing both the video and audio together.

Actual Behavior

The export finishes, but Premiere creates the MP4 and AAC audio as separate files. The AAC file is also being given a long automatically generated string of characters after the original file name.

This is happening repeatedly when exporting from Premiere Pro Beta 27, so it does not appear to be a one-time failed export.

I have attached a screenshot showing the two files that Premiere creates after the export.

Please investigate whether this is a current Beta export/muxing issue. I would be happy to provide my export settings, project information, or additional testing information if needed.
