The initial scene is a boy playing football in slow motion,
in an open frame, but the camera angle is a close up of the boy’s feet, with a
pan to follow the ball.
The camera then whip pans to show a mid-shot of several
groups, with the focus being on the groups and then out of focus elsewhere.
The camera then zooms in closer so that a close up is
achieved, with sudden changes of focus.
The camera then cuts to an extreme close up of a drill bit
being placed in the drill, and then cuts back to the playground as the camera
pans slowly between groups, changing focus but staying at an open frame and
mid-shot, which shows the chaotic environment of a playground.
The camera again shows an extreme close up of a closed frame
where a boy is putting on safety goggle and turns on the drill.
As switch / reverse / switch is used as two girls are having
a conversation about someone, then the camera whip pans across the playground
again to show another conversation again at a mid-shot in an open frame.
The use of the open frame, mid-shots and whip panning is
mainly to show the chaotic environment of a playground, which is achieved
through the hand held camera as if someone is watching the people, like a point
of view shot.
