True, normally you have to decide to just use the description to do metadata retrieval to link up the files and make sure that the Avid MC export is set to Copy all media.
That way the files will line up anyway as they will relate to the start of the files.
It is a mxf thing…
Avid MC in all mxf based workflows (you have to use mxf to be able tu use multiuser workflows using Avid servers) changes how the data is stored and read from the mxf wrapped files. And Nuendo can’t read that (yet). It is actually in the mxf files themselves, but not at all stored in the same way as in a regular bwav.
This is one of the reasons we still mostly use Audio EDLs and Titan to conform our dialog.
However field recorder audio import is a great time saver if you need to find a missing cannel or what n ot after all the mxf files have been replaced with the location sound files themselves.
