Flying object in Brazil clip: insect or something else?

The poster uploaded an enlarged version of a short clip to make it easier to view. A landscape appears in the frame, along with what the poster calls the flying thing from the Brazil incident. The poster asks whether it is an insect or something else.

The object is not clearly visible, and there is no information verifying the footage. The clip therefore does not establish what the object is or reliably connect it to a particular incident in Brazil.
