What went in
the establishing frame — no additional references for this input
The skateboarder carves across the bowl and up the far wall, catches air at the lip and lands cleanly, while the camera whip-pans to follow him and then pulls back fast. Fast, coherent motion with no cuts. The sound of wheels on concrete, no music.
