I went to prepare my Nuendo project to export an AAF for Pro Tools yesterday. I first started by going to File → Export → AAF, set my media folder for the AAF to a DIFFERENT location (than project) and did a test export. Next, I tried splitting out my 5.1 wave file events to new mono tracks (so I can retain the metadata event names in the AAF). I then went to re-export a second AAF and was going to clear out the AAF folder contents before doing so, and noticed an ‘Audio’ and ‘Images’ folder containing all of the split channels.
TLDR ISSUE:
Split Channel Render path appears to use a recent AAF Media path instead of defaulting to project path under certain circumstances. I did not notice this issue using the ‘Render in Place’ command.
