I have performed an AAF export of audio from the same sequence, from the same project using Premiere Pro CC 2015 and 2017.
The AAF from CC 2015 gave me the file names in the left column in the image below. The export from CC 2017 gave me the file names in the right column of the image below.
Is there a setting somewhere which tells the AAF export to do this?
As along with changing the names to hex strings instead of the merged clip names, it has also stripped the meta-data from the audio files.
Meta data such as scene and take number and channel name.
I can't think of what this setting would be called, and therefore can't find it in any forum posts.
Searching for AAF turned up unrelated issues.
