German Jet, Bird and another thing?

I took it out of the window today on April 10th, 2024 at ~3:30 p.m. in Hessen, Germany. I actually just wanted to record the fighter jet until I saw the black object on the video, which turned out to be a bird at low speed of the video. But what is at the beginning the object high above the jet and much further away, which shoots extremely quickly through the clouds and at the end the black dot in the upper left corner, which is just came across, which is why it is either an object in the airspace or just an insect that just flew onto the window. Your Opinions?
