I think it was a bug, and only appeared to be going fast because it was close to the camera.
To be more specific, the camera had a light source, so this could have been a bug that was flying through the light that was being cast by the
camera's light source.
We know it wasn't "far away" in the sky because when it first appears, it is in front of a building. I think it was "very" in front of the building
-- i.e., close to the camera and its light.
EDIT TO ADD:
Here is the object (arrow added by me). As we can see, it is somewhere between the camera and the building.
