It doesn't look like dropsy to me. Not from either video or the stills. Unfortunately, IMHO, the fish has been out through unnecessary medication, which isn't a good thing. Notwithstanding the poster who claimed to have a fish with dropsy that was very active, when I had a fish with dropsy, she was very inactive, and only moved to try and get food.
As Colleen has pointed out, dropsy is caused when the fish's internal organs have failed. I don't believe that any living being that has suffered the failure of its internal organs is likely to be behaving normally.
IMO, that is a very healthy, very pregnant fish.
