Strange Anomaly speeding through the sky over Osijek, Croatia

The last months, the eyewitness had seen unidentified aerial phenomena in the sky over Osijek, Croatia. On September 11, 2020 when searching the sky again for UFOs and Spheres he accidentally recorded a bullet-like object that flew through the sky at an incredible speed.

It is not clear if it is a (Tic Tac) UFO something else like an insect or bird since it looks like the anomaly flies close to the camera, making it appear as if the object is flying at a very high speed, but I could be wrong. The photographer sent the video to Mufon for further investigation.

The anomaly moves from left to the right and can be seen right at the start of the video, followed by a slow motion clip of the object.
