Comment (by DonMoir):

 The original silent-boot.mov has a metadata rotate value of 180 degrees.
 It is up to any player or converter to take this into account. This
 rotation value orients the video to normal viewing. Sadly, some players
 and converters do not take this into account.

 It would even be worse if you manually rotated it and the metadata rotate
 value was left in place in the result output video. Now it would be upside
 down in programs that do respect the metadata rotate value.
