ERROR "Adding essence data to AAF file"

Gordon,

Thank you for the XML.
I wanted to ask if there was any more text to your X2Pro error message that you get?
Is there any sort of Suggestion information that comes after the "Error Reading audio data from asset [-50] [error in user parameter list]" line?

The error message could be caused by a few different things.
1. The clips could be on an NTFS drive that is not recognized by the Mac.
2. The MOV file could be referencing WAV audio that it does not know the path too or that X2Pro does not have access to.

Could you check to see fi there is any more details to the error message and post those if there are?
Second to that, if you could try removing the c_50_1 clip from your timeline and then re-editing it back it,in may fix the problem.

Please let us know how you get along.

sorry, your XML must have not been attached.

Here's my FCPX XML, thank you so much for responding....

Could you please provide us with your FCPXML,please?

Adding essence for asset [C_50_1] to AAF file
Adding essence data to AAF file for portion 0 of asset [C_50_1]
Reading audio data from audio extractor : 1048576 samples
Failed to read 1048576 samples
Error Reading audio data from asset [-50] [error in user parameter list]

I'm editing in FCPX with compound audio clips that are then compounded into another clip with two camera angles: one Black Magic 23.98 and one Canon 29.97 in a timeline that is 23.98.

"C_50_1" happens to be the Canon camera with camera audio but no external audio synced to it.

I have no Idea what this error message means.

I have X2ProLE but have upgraded (I guess? Supposedly?) to Pro.

Please advise, I cannot for the life of me manage to deliver my movie to my sound editor.
