Baylands, take T2 (cycling, 4K100), 20 seconds from the drones' own pixels

How it's made. A 3D body fitted on every frame to all three drones gives the shape. Each pixel of it is coloured from the drones' 4K frames at that instant, from whichever drones see that point best. Nothing is generated. The body's outline matches the athlete in every drone view (silhouette overlap 0.94–0.97). The field and tree line are built from the same footage with the athlete and their shadow removed; the shadow you see follows the real sun.

Where it breaks. The free camera is limited to the heights the drones covered; hands and other small, fast parts are the least accurate. Drone 3 has no pose for the first 4.6 s, so early frames use two drones. The field is flat by construction, so anything standing on it apart from the athlete is flattened.
