Observed light moving in manner not consistent with aircraft

Light (white in color) appeared steady at times and appeared to move short distances in irregular pattern. At 1 point shape seemed to change from circular to a hexagon type shape. There was a distant aircraft in the long video that came into view briefly. I tried to keep camera steady, but did move it to accommodate the aircraft (blinking light) that came into the lower right of the frame. Unknown if aircraft was in position to observe unknown craft.
