Video prompt: an incredible view of a man running on a field, possibly during a track and field event, as he leaps over the finish line and jumps in the air. The scene is captured from above and showcases the runner's impressive performance.
Defect: Deformation (any reason involved with a movement)
Explanation: The athlete’s running posture on the track appears highly unusual: their legs occasionally distort and merge together as they swing and cross over, resulting in a twisted, deformed stance. This creates an overall blurred and unnatural appearance, with the legs seeming to fuse and move in an odd, contorted way.
