I didn’t hit the ball. Why did the app detect a swing? (Blast Vision)

• The app is looking for small objects that move like a hit ball, but sometimes it gets confused by other movements. For example, a practice swing, pitched ball, walking in front of the camera, background movement, or shadows on the ground can all appear as a moving ball. We’re continually working to minimize false detections, but if they do occur, simply delete the false swing from your session.
