Film from the angle (front, side, rear) that best captures the event (most track and jumps events are best filmed from the side; some throws are best filmed from behind the throwing circle). If you feel you need to film from more than one angle that is ok.
Take a few clips of each event so you have a few to choose from
Plan a specific time to capture your clips and give your athletes notice that you are going to film them
Make sure you have the permission of the athlete and their parents to capture the athlete’s image
Save your clips and name them so they are easy to recall on the day of your evaluation.
