Create an AAF in Media Composer, take one .mov file (from ASWF samples), transcode it to an MXF file, add it to a sequence in Avid and export an AAF.
Now try a round-trip with otioconvert -i punchline.aaf -o punchline.otio followed by otioconvert -i punchline.otio -o punchline2.aaf then punchline2.aaf should conform and link the media via Avid UID as-is?
Dumping the original AAF and observing the AAF metadata in the .otio file there seems to be a discrepancy with the MobIDs.
