UFO Sighting in Twin Lake, Michigan

Object appeared to my left in the sky above my house. At the very beginning of the video you can see one at the top left and one coming in from the right over my house, the one on the left flashes a few times and then shoots straight up. The other one comes in moving very erratic moving forward, back, up, and down several other small flashes appear all over the frame, but they are only flashes.
