An update on this. After some cross global collaboration with Jude, it seems that if the movie opens in QT Player as 16:9 then the export/import works as expected. If you take a movie that wasn't flagged as 16:9 when it was created (opens in QT Player as 4:3), then the export/import doesn't work properly.
This is definitely a change from previous versions where the anamorphic flag at the clip level always took priority. Have reported it to Apple.
