When I first saw one of the ATR 72s I speculated that with that long fuselage, there would need to be a fairly careful series of checks so as not to inadvertently shift the C of G outside of the safe operating range - especially the aft limit. It would seem ever more critical with the narrow chord wing. This one seems to have had a full list of passengers so there's nothing to see there in terms of passenger loading. However in the early stages of the video, the nose high position is suggestive of an aircraft at the aft C of G limit or beyond. No-one else has made any observation along these lines, so I'm typing very softly here - it seems likely that everything was in order there as it should be. And yet, I continue to wonder if something was overlooked. The report will tell us I'm sure.
