Each clip is one punch on a heavy bag: 0.7 s before it until 0.7 s after, on a loop,
cropped to the boxer. Rate whether the punch is snapping (hits and snaps straight back) or
pushing (rests on the bag, pushes it, drifts back). The skeleton is drawn on the clip (the
Skeleton button hides it) and alone on the left, the punching arm in orange while it punches; the compass is the
boxer's facing angle seen from above, camera at the bottom. The timeline shows every punch on the clip, lead
hand on top, rear below; the one to rate is orange. Keep your scale the same throughout.
