Witnessed a shimmery/metallic object move at a high rate of speed from right to left, left to right, and then sit stationary

The object was very abnormal. I’ve seen plenty of planes, helicopters, weather balloons, and I enjoy watching the night sky. This was nothing of the sort. The object had a chrome shiny exterior, and reflected light as if it were a mirror. It moved much faster than the planes I’ve seen, and seemed to change direction in an instant. The object stopped and remained stationary, so I grabbed my phone and began recording. I was in a work van that was pretty dirty so getting good footage was hard. I noticed the object began shimmering, before moving southwest and disappearing. My boss was the driver of the vehicle. He is a church minister, and a devoted Christian. He was the only other witness in the vehicle with me. He had trouble seeing it while driving. When I reviewed the video I took, (IPhone 13 Pro Max) I noticed a strange interference on the video that created blurry pixels on the objects near me in the video. The video is poor, but my eyesight is not.
