Which angle to film your bodyflying
1
Event and Training windtunnels - similar

Before training, stand the camera where will seats the main audience (or judges), or at least where it can capture the performance from that direction. If that’s not possible, place the camera in any other convenient location.

2
Event and Training windtunnels - different

If the entrance in your training wind tunnel is positioned differently from the one used in the event, if it possible and comfortable - set up the camera according to the layout of the event windtunnel.

This will help you adapt more quickly, as it will build muscle and visual memory aligned with the directions of elements, tricks, and combinations in the actual event environment.
