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.
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.
