X2Pro can't cover XML to AAF

I'm not sure what you were searching for in the fcpxml. If it was the file path, then you have to percent encode the file path before you search, which in your case means replace the spaces with "%20".

If I search for "/Volumes/4GOT10%20Edit/4GOT10%20SOURCE%20/VIDEO/DAY%2011(2:18:15)/URSA(A)0030/Blackmagic%20URSA_3_2015-02-18_2321_C0031.mov", I find it on line 3784, and I can see that it is used in 2 places in your project, and in both cases the clip's name is "78AK_2_MOS"

Are you able to provide that MOV file so that we can take a look at it here?

Hi,
I'm having trouble creating an AAF from an XML in X2ProLE.
Here is the error message:
Writing AAF file
Adding assets to AAF file
Adding essence for asset [78AK_2_MOS] to AAF file
Adding essence data to AAF file for portion 0 of asset [78AK_2_MOS]
Reading audio data from audio extractor : 699050 samples
Failed to read 699050 samples
Error Reading audio data from asset [-50] [error in user parameter list]

Suggestion: Try transcoding this file and any other files of the same audio format:
[/Volumes/4GOT10 Edit/4GOT10 SOURCE /VIDEO/DAY 11(2:18:15)/URSA(A)0030/Blackmagic URSA_3_2015-02-18_2321_C0031.mov]

No AAF file has been generated.

I've tried searching for the code when opening the XML in Text Edit and it can't seem to find the code. I've attached the XML for your perusal.
I'm on a very tight deadline and any help would be greatly appreciated.
Thanks!
