Totally stumped on this one. Exporting a :60 piece for a client and notice that the last 3 seconds of audio are completely cut off in the export. It plays PERFECT in FCPX, this is only happening on the export.

Tried restarting
Tried trashing preferences
Tried rebooting
Tried getting rid of any fades
Exported several different ways (through compressor, not through compressor)
duplicated the project and regenerated render files
converted the audio file from an AIFF to a WAV and dropped it in, still did the same thing.

Exported separate audio roles and it's the dialog that cuts out. When put together, it seems to cut out all the audio all together.

So I'm wondering if anybody has had this issue or has any suggestions on how to troubleshoot and what to try next?

Much obliged. This one really has me perplexed.

Wow, not seen this one in awhile. A couple of updates ago. Try adding a Gap Clip and making it longer than necessary, extending the length of the whole piece.

Or try trashing the render files for both the Project and referenced Events.
