I noticed that PM does not show some vital (at least for me) info for movie files (shot with the Nikon D4). The missing info is a.o. the model name and the lens used. The info is present in the file itself, (exiftool finds it just fine), but not found by PM. It would be great if you could add this :-)
As a side note, I also noticed that PM creates a .xip file with (to my knowledge) no important info. A .xmp file is created as well, but I guess this one is required as PM is unable to embed the IPTC info into the .mov file?
If you need a sample file, just let me know and I'll create a dummy file.
